View Full Version : MY PSP got Partially Bricked!!! HELP!!



Apoklepz
June 5th, 2006, 19:10
To begin with, I own a genuine 1.50 PSP. I was using Flashmod today to install some fonts, and that worked like a charm. Later I decided to mess around with the menu names through patching of a file named topmenu_plugin.rco through the Menu name change program by Loco...And Dammit!!! I did everything right and later used flashmod to flash the menu names with the patched file I used...Now my PSP will only play UMD's when inside the UMD slot...If there's no UMD, it just loads normally as it always does, freezes at the menu background (the Icons never show) and then crashes....FAAAAAAAAAAAAAACCCCCCCCKKKK!!!! I'm such a dumbass! I knew this day would come if I kept messing around with hacks. I'm really pissed!
Sorry for the language Wraggster but I never curse here, and I think you'd understand how I feel.

Is there any way out of this nutshell? I need some help. I'm desperate!

My PSP is now oficially the equal of a game boy...Meaning it only plays games. There's no way of going into the flash, as I can no longer access it thorugh USB or homebrew...I can still re format my Memory stick through my PC but that won't change anything...I don't have access to system settings, so that's not gonna help either...
Any ideas or opinions??? Please help me out here if you know of a fix.

Tampering with your flash is never a good idea, maybe you could try updating to 2.0 off a UMD.

damn dude that sucks i dont know about changing the fonts or startup sounds but i would like to learn how to if you find a way out of your problem could you pm and help me change or edit my psp

Thats unfortunate. I feel so bad, i wish I could help!
This post is really just to say hello to you, longtime! Hope everything else is well with you man. Try an update through umd as the last guy said. Things cant be that simple though!

Apoklepz
June 5th, 2006, 19:29
How can I upgrade to 2.00 via USB? I can't access anything in the menu, not even the USB port. Please explain.

****Sorry I read it wrong**** I will try to update through UMD...I guess it's my only chance.

Hi Bullhead....yeah man I'm really pissed...

I'll have to try a UMD version 2.00 update once I get home, I don't have any of those games on me right now. I do have the audioslave concert though and that has a 2.00 update, but It's not even letting me through after I power on the PSP. I'm simply getting the background freeze.

bullhead
June 5th, 2006, 19:51
gta has a 2.0 update.

Apoklepz
June 5th, 2006, 19:57
Yeah I know, I have it at home...I'll try later. Right now I happen to have on me 4 UMDs:

Lumines - no update on it
Coded Arms - 1.50...which I already have installed
Pursuit Force - 2.50...No way, unh uh...It's not working either, anyways
Audio Slave concert in Cuba - 2.00...but it ain't working

So considering I've tried two UMDs with higher updates already, and I've gotten squat, I think I'm stuck in the same place....UUUUUUGGGGGGGHHHH!!!

How much does a flash memory go for?? Anyone know? Do they sell them with firmware 1.00 or 1.50 already installed by default?

BTW guys, thanks for the moral support...as you might already know, I am having a really sheety day.

Apoklepz
June 5th, 2006, 20:09
Can anyone confirm me something... When you highlight a UMD update through the menu, are the other menu icons still visible? Specially if it's a 1.50 PSP with a 2.00 UMD in-slot....I just wanna know, can't remember right now.

The thing is, since my "topmenu_plugin.rco" is probably corrupted, I am not able to see anything past the PSP boot screen that reads
"Sony Computer Entertainment" (except the background pic)when you turn on a PSP. So the only way would be to access the update without any text showing in the PSP menu desktop....and I don't think that's even possible.

Although, my security settings were on, I get the message to input password at startup...I don't really have a password, it's just a way of deciding if you want to play the UMD or go straight to the homebrew instead, when I start the PSP....Now I really miss homebrew.

Apoklepz
June 5th, 2006, 20:13
Something just occured to me!
I think I'll try the UMD swap method trick!
I'll run Lumines and then swap it with the Audioslave UMD.... I'll post back if anything.

Aw shucks... Didn't work either...it just crashes into a black screen after the MS light flickers for a few seconds.

Sorry to hear it man :p
try updating the eboot way

Apoklepz
June 5th, 2006, 21:17
I can't access any eboots.
Now I simply have a PSP 1.50 that plays up to 1.50 version games, and a PSP 2.70 which I bought two months ago... I guess this is just how SONY would have wanted it.

Can someone please confirm my #8 post query. Please.

try using links 2 (the homebrew web browser for psp 1.5) to download all necesary homebrew/updated and see if that works

also, try to use links to download a new topmenu_plugin.rco

Hopefully the modchip will fix your problem.

Apoklepz
June 6th, 2006, 17:43
Yeah I know, the modchip fix is the only thing I've thought about, thanks for pointing it out...

But I'm curious...Is there any way a homebrew shell application, like say IR shell, Psix or Artillery can boot from startup, instead of the regular PSP menu?

What I mean is, this would allow me to bypass the PSP default menu and be able to load a flash custom app like Flashmod, and then I could restore the original "topmenu_plugin.rco" and get my PSP to function normally again...I hope.

what happens if you put in a game which requires an update, i know you cant update from the disc initially, as that needs to be done via the XMB, but maybe if you load up a game it will then take you back to the update symbol. also try UMD movies and Music, as they cant boot on startup.

if that doesnt work, my only guess is serial port access, but i know nothing about it other than you get direct access to the psp files

try using links 2 (the homebrew web browser for psp 1.5) to download all necesary homebrew/updated and see if that works

also, try to use links to download a new topmenu_plugin.rco

Please explain, because my dilemma here is that the main PSP menu got corrupted. That means, I cannot acces anything, not even the settings, except a UMD in the UMD drive.

Also, any UMD's that require an update higher than 1.50 will not load, not even the update prompt, resulting in a freeze followed by a system forced shutdown... So, I'm limited to playing my four 1.50 UMDs that I already beat a long time ago. Save works fine, too.

Apoklepz
June 6th, 2006, 17:58
My video UMDs don't even load. I have two 1.50 movies: Spiderman 2 from the initial bundle pack, and Hellboy. I tried both and I just get the background freeze into a system forced shutdown.

OK...Just to clear things up a bit for people who are first timers to my shameful thread:

- I own a 1.50 firmware PSP with few games (6 to be precise)

- Yesterday, the GTA style customs for PSP came out, and I've always wanted to have that GTA font for some crazy reason.

- Soooo... I took the fonts for a spin with Flashmod v0.3 with font customization, and it worked like a charm.

- Then I got all curious about the whole deal with changing the PSP's menu text names and I thought I'd give it a try...you know, just for kicks.

- I did my research through various forums and found out it could be done with the same flashmod application, but first you had to patch a file called "topmenu_plugin.rco" with Loco's PSP Menu edit. Having that done all that was left to do was put the patched file on the root of your MS and run it through flashmod...Simple, right?

- To my complete horror, I now have a partially bricked PSP that only plays 1.50 games...Kinda like a Gameboy but whith better graphics XP. So it Sucks for me. Thank you.

- My PSP's current functionality depends on a 1.50 or lower UMD to actually be able to at least play SONY PSP games. I do not have any access at all to the PSP desktop menu interface (were the icons first appear) or as veterans might call it, the XMB.

-This means it cannot access anything other than the UMD inside the UMD slot. No Photos, No Videos, No Music, No Homebrew...not even a perfectly functional Memory Stick....All I get is my customized desktop background to freeze, and after 9 seconds the PSP automatically forces a shutdown.

+++ This also means I have no access to the PSP through the USB cable, since I cannot trigger it. But I can still put stuff in and out of the MS through my PC's card port.

So I'm currently open to any suggestions and opinions that might help me on my quest to find those precious features like homebrew again.

Thanks.

The modchip will have to wait. I need to know if it will operate straight from the psp interface or from a second disk, kinda like a dos mode on PCs. If it runs right off the PSP menu interface, then I'm screwed either way, if I get to spend money on actually buying it....But there's always hope, right? At least I don't have a complete brick like some people have suffered, already. My brick plays games!

I'll do my research on the serial port thing and I'll post back with my findings. But while I'm at it, I'd appreciate it if someone with any knowledge on serial port access could help me out. Even a link would help. Thanks.

Send your PSP to Sony and say that your PSP died while updating.

Heh. That's clearly not an option for me. I don't want to end up with two 2.70 PSP's or a higher update when they send it back to me... And second, they'll probably notice that I've tampered with the device enough, seeing as my warranty was voided personally by me while doing the Dpad mod three months ago...

Being that the file needs to be executed from the PSPs internal flash memory, it is useless to have it in the root of the Memory Stick, unless you run it through a homebrew application like flashmod...But I can't access homebrew or anything else anymore.

Don't feel stupid, it's good to ask...It's one of the two ways you learn stuff.

...But, don't feel bad. After all there's still means of hope through what the U.P. Modchip can offer when it's finally tested by someone. So it just come down to waiting for me.

BTW this sunday is my birthday and I won't have any homebrew or emulators to play with:(
But I'm glad I'm going to enjoy a nice Lobster and some Stone Crab with my wife at our favorite local seafood place, Monty's... Then we'll probably got whatch X-men 3 which I haven't been able to see yet because of recently moving to a new house.

So my PSP can wait.:D

Do you know of any good source where to get one?

June 8th, 2006, 18:24
my advice - and i know its not helpfull so sorry - is just wait till this modchip gets released. it claims to be able to restored bricked psp's which yours is. its also the cheapest option you have right now except possibly sony support but they will put 2.71 on it so....anyway good luck with it - dont know what i would do if that happened to me.

you could try ebay for a psp with a broken umd drive or mem stick slot

broken psp systems should sell cheaper than a new one

then you could just take the flash memory out of there and put in your psp

Especially at Monty's were they keep em coming! They even put a bib on your neck while you munch your way through them... It can get quite sticky and smelly, you know! LOL.

Yeah, I'm fully loaded with thesis midterms too, I barely have the time to watch the Fifa Cup and the NBA Finals...but this weekend I'm just gonna Shlax (combination of shut up and relax), because it's my birthday!.... I'll cry if I want to, though. meh.

Hey everyone! Thanks for the kind words! As for the modchip, I'm still waiting for visual proof that it can fix a brick, before I buy it. Bullhead and Accordian boy, the best of luck to both of you with those exams!

Anger
June 12th, 2006, 23:38
well that is a good suggestion, however correct me if im wrong but doesnt flashmod write the fonts to flash0 not flash1?
if thats the case this idea wont work. it is however worth a try. i have to admit its something i never thought of. if flashmod writes the fonts to flash1 this may well be a fix for everyone that has been having this issue. ill have to go find out where flashmod writes the fonts to.

*EDIT*

ok did my research - it does write the fonts over the psp's originals so it is my belief this trick wont work. let us know if it does.

Apoklepz
June 13th, 2006, 16:51

Yes sir... I just get the parental control password check (no imput needed really, I just use it for means of not loading the inside UMD I have in the PSP & going straight to the homebrew).
From there I either press X to run the UMD or O to go to the XMB, but O freezes and the XMB never shows up, then the PSP just powers off after ten seconds.

If I try to run any 2.00+ UMD game or movie I just get the background freeze to the PSP forced shutdown.

June 13th, 2006, 23:13
actually i think what he meant is when you turn on your psp and just before the text loads after the background (and i presume where it crashes/freezes on yours) i think thats when to remove the battery because just before the text loads the psp reads from flash1 - removing the battery then may corrupt the flash1 and force it to restore defaults. thats what i think he meant.

also never remove the battery while firmware updating - you WILL get a brick for your trouble.

jman420
June 14th, 2006, 07:08
wait, so you also changed your background?? to have custom background and special font?? is it any wonder it bricked, you cant mess with that much stuff in your flash, its your own dam fault you got it bricked, let this be a lesson to everyone...

I have a 1.5 f/w psp, 3 games, 6 movies, every single good speed emulator, with original background (incliding the colors change each month), original font, and nothing changed other then downgrading it from 2.0 a few times...

I dont mean to be mean, but I cant feal pity for someone that changes the system in ways a psp is not to be changed... its basicly overwriting the font already on your flash, and if it overwrites and isnt the same size, it will either leave bits of information at the end of the file, or overwrite the files in front of it..

A flash rom chip is somthing that doesent automaticly re-organize all the bits of each file, thats why it will overwrite somthing that isnt the same size... but! the F/W made by sony compleetly re-writes the flash, all files get copyed over and changed.. without leaving any overwriten bits, nor any gibberish bits...

thats why when you remove your battery while its re-writing the flash (updating the F/W), it doesent get all the files, its gets some, and still only partly copys over the other files already on your flash chip..

the new modchip would probobly fix your psp, if you have the skill to install it.. and obviously, if you can afford it..

but yeah, good luck getting it back up and working.. it definatly would suck for me to break my psp, especialy with the Resident Evil remake and all :p

Apoklepz
June 14th, 2006, 19:06
Well thanks. Changing the background is not a big deal as changing the font or customizing the XMB menu names for the icons. Background customizing has been made easy since the first days of PSP hacking. Some might remember homebrew applications that would help you modify your monthly backgrounds like, PSpersonalize and others done by WAB and Team Emergency Exit... All it requires is you have 24bit BMP format images with a resolution no bigger than 300X170 in the root of your Memory Stick, and name them respectably after each month...January would be 01.bmp and so on. It's a pretty old hack known by many 1.5 PSP users, and even though if you mess up with the resolution, there's no chance of corrupting the flash, as the results seem to only affect ICON0.png files for homebrew...a fault that can be corrected by re-editing the custom background's resolution correctly.... So this hack in no way messes up the PSP's flash.

The font hack is much trickier, and even though I have managed to execute it without damage to the flash, I will not post the how-tos for it here, because some of you here might not follow directions correctly and end up bricking your PSP... I've already heard about a few people in the forums that have completely bricked their PSP's flash with this hack.

Now, what messed my PSP's flash and bricked it from acessing anything other than 1.50 games is the third hack I will mention in this post. MENU NAME CUSTOMIZATION
There is a file in the PSP's flash called "topmenu_plugin.rco" wich I guess it's the command file that allows to display every single word that goes in the main menu of the PSP. I learned that this file can only be manipulated via Loco's menu edit application for windows. Everything is intricately placed in this file, so that means if you go along and mess with it through word pad or any other PC text editor, then flash it through your PSP, you can go ahead and forget about viewing movies, listening to music and playing homebrew on your precious little handheld.

I still don't know what went wrong that day when I was editing that file, but if it helps, these are the custom menu names I was going to add(btw, I did this after having already sucessfully installed the GTA font):
-Photo would become Images
-Music would become Tunes
-Video would become Flicks
-Games would become Play

And just when I was gonna go play some Lua...I couldn't. At least that modchip is coming out soon, and I finally have the money saved up.

I now It's my damn fault. Of course it is. That's one of the reasons why I started this thread, so people would see the downside of hacking your system...It not always ends up how you want it too, that's my opinion.

On the subject of backgrounds...

I created a super small background for my 1.50, 1kb instead of 6kb saving loads of memory for firmware fiddling.
I made it 1 pixel wide by 272 pixels high.
The psp then stretches it to fullscreen.

Stretched example below.

I know its bit minimalistic...but i prefer the horizon effect.

Well yeah...I mean, I don't wanna sound like a prick or anything, but if you read in the first pages of this thread, I already tried updating with both 2.0 UMD's that I own...GTA and Prince of Persia, and they both end up in a forced crash...I suspect the background icons need to show up when the PSP asks you to update, and that's why it crashes.
But hey, thanks for stopping by and helping out.

Well thanks, that WOULD help a lot, wowzors. And as to how it would fix a brick or not, here's what that old article said about that:

"Since U.P. provides a secondary flash which the PSP can boot from, it can even be used to restore a PSP which has been "bricked". "

How? I have no clue...but I've come to the conclusion that since you'll actually have a second "working" flash memory, which is the UP Modchip, then your PSP will "work" again if it was bricked and non working...But as to the UP modchip actually fixing the PSP's original flash memory and runing both flashes...I still doubt it, and that's why I haven't bought it yet...Guess we'll have to wait and see...

Remember, my only doubts here are on how the UP modchip can fix the original "bricked" PSP chip.

i would say they could do it one of 2 ways.

1. copying the files from u.p. to psp's flash either using an inbuilt function or by using a homebrew app that can manually copy all the files to the psp's flash.

2. (and this is more likely) being able to run the sony updater program after botting from u.p. and then switching to the psp's flash for the updater to do its thing.

number 2 is most likely because from what i understand of the updating process the updater prepares the flash in a way so that the psp knows exactly where each file is in the flash memory (kind of like preparing a boot sector on a floppy/hdd). now i may be totally wrong here but it is probable that this is what needs to happen.

ill be interested in knowing exactly how it can be done in case i decide to buy/install the u.p. myself so someone who has it please let us know.

theres software that lets you flash a psp with the up mod chip so i think thats how it lets you unbrick the psp besides the secondary flash

June 29th, 2006, 12:55
from my understanding that software is only for flashing u.p. however i could be wrong. would be very cool if it can flash the psp,s flash too.

Basically a bricked psp is where whatever program that caused it has edited/rewritten the flash in the psp so that it will not operate as it should do (not work!). So the modchip physically replaces this now unusable flash module. And with a new flash in the psp that has the correct code... hey presto, i works again.

Anger
June 29th, 2006, 19:59
so basically what your saying is - a bricked psp even with u.p. - cannot have dual flash features.
im sorry but the ads say it can fix a bricked psp.

i see why you might assume that it replaces your psp's flash but it doesnt actually - it operates alongside your psp's own flash.

Gizmo356
June 29th, 2006, 20:04
it does unbrick it because it reaplaces the old flash and gives you a secondary flash so you buying two

Anger
June 29th, 2006, 20:14
thats not quite what i mean - i understood the advert to mean you can repair a bricked psp not just use u.p. instead of the psp's own flash.
of course i could have been wrong but there must be some way to actually fix the psp's own flash with it otherwise those with bricked psp's will not be able to use that new bios thats coming out if u.p. doesnt actually repair the bricked psp's flash.

Apoklepz
June 29th, 2006, 20:34
OK, I read elsewhere that the current bios supported by the U.P. mod chip only serves to make the UP chip function as a regular PSP 1.00 or 1.50fw would, it depends on whichever version of the current bios you choose to install. They claim they will release their next bios called "Epsilon" soon, and that this bios will be the one that will not only have 2.00+fw features and still play homebrew, but it'll restore the "bricked" PSP flash through a shoulder button "flash switch" method. So I guess this at least prooves everything discussed here already about the UP mod chip. But I'll still wait for a video.

No, that won't work. Unless somebody knows a game that will let you update without returning to the menu first? Don't think one exists...

I have the exact same problem as you, Apoklepz. I am currently looking into a way to flash the PSP through the serial port adapter (look here (http://nil.rpc1.org/psp/remote.html)) but so far nobody seems to know how. Sony tech people apparently flash the system through the serial port, but again, no info on how.

There has to be an easier way to do this. We just need some way of accessing flash0. If there was an exploit within a 1.5 UMD game it would probably be much easier. That's probably the first step to a non-hardware solution to this problem.

But hey, I'm open to hardware if it'll fix it, just not an overly expensive modchip that is too difficult for me to solder. I'd just buy a broken PSP and hope for an older firmware before I did that.

What about buying a new motherboard?

cptmarginal
July 1st, 2006, 23:08
I have thought of buying a new motherboard, but they usually run about 100 USD. Still a bit much for me...

I think buying a broken PSP and taking out the working motherboard would be cheaper. I'm thinking of sending it off to this guy (http://secure.llamma.com/catalog/product_info.php?cPath=66_90&products_id=542) and letting him take care of it, as it would be a bit cheaper.

Not before I watch eBay for a few days and look for a deal on a broken PSP, though...

youre best off getting a modchip. The modchip's firmware loads by defautl, so it will work here. And then from the modchip firmware, you can flash a working topmenu_plugin.rco to the fash and fix it also

hate to be pestimistic, but youre probably not going to find any other solution

cptmarginal
July 3rd, 2006, 19:21
Also, the horribly over-priced and difficult to install modchip hardly seems like the best solution to me, especially when the motherboard can just be replaced.

It seems to me that it would be quite easy to unbrick a PSP (afflicted this way) if someone was to code a save-game exploit for a 1.5 UMD game.

bullhead
July 3rd, 2006, 20:09
The motherboard is obsolete now with the new downgrader being released. Newer psps with the new motherboards dont work with the downgrader, and they are not compatible with the mod chip either.
And with developments of Devhook its only going to get worse for the modchip.

Apoklepz
July 6th, 2006, 22:27
OK, I just thought I'd bump my thread because of all the recent downgrading going on recently, thanks to a lot of hard working devs out there...Even though I still hold a brick in my hands, I'd like to share my utmost respect to all these great guys/gals working hard for the community.

Now that being said, I thought about a lot of possibilities that could help us "bricked" PSP users.

IS IT POSSIBLE TO PLAY HOMEBREW ON A BRICKED PSP AND MAYBE EVEN POSSIBLY RESTORE IT'S FLASH?

As we all know, the answer is "NO". But think about it...If somebody could work an exploit through a 1.50 or 1.00 UMD (a la GTA:LCS) we could indeed play homebrew on partially "bricked" PSPs (meaning they only play inserted 1.00 or 1.50 UMD) and possibly restore the flash through running any PSP Flash alternate applications like Flashmod and a bunch of others.

Can somebody please give this some thought? Now that downgrading 2.6 and 2.5 PSPs to 1.5 is possible....anything is possible...just my two cents.

i remember fanjita saying wipeout was a likey candidate for an exploit. but nothings been done.

sorry if this has been mentioned, but, if you put a game in which requires an update, and only close the drive just as the psp boots up, so it doesnt have time to load the umd, do you get to see the umd icon?

Apoklepz
July 6th, 2006, 23:03
Wipeout, huh? Here's to wishing somebody answers my prayers soon...

Hey, if it's been mentioned or not, it is still helpful to newcomers to the thread...no problem.

The problem I have with my PSP is that I messed up the text in the main menu, so I really can't see no icons either... Once the background loads after "$ONY COMPUTER ENTERTAINMENT" shows up, it either freezes at the background, with no icons or text showing, only a faint battery icon in the top right corner...or loads the inserted UMD...but only if it's a 1.50 or less UMD.
If the UMD is more than 1.50, then I just get the background freeze into a forced shutdown.

Anger
July 7th, 2006, 00:08
i think your case is unique. heres my thinking behind this.
your problem was caused by trying to change the text on the xmb right? well i think that even if they find an exploit it will not be of any use to you. the reason is that to save/load you are dropped back partially to the xmb which performs the save/load. now if you can save/load without problem then an exploit will help you. if thats the case then the damage done to the xmb is confined and any game exploits through save/load will work.

people have been looking for exploits in games since day 1, thats why the only one that exists is gta. it isnt just because its the best game its because it was badly coded. now thats not to say there isnt other possible exploits, im sure there is, but finding one and then being able to use it will take time. your fastest and best hope is a new motherboard or the modchip.
sorry to be the dampener but i think your out of luck unless someone finds an obvious hole in a game and manages to exploit it.

now just a thing to try - what happens when you hold the down key while starting the xmb without a disk in the drive? if you hear the click sounds there may be a way to get to the update. if you dont then nothing ventured nothing gained.

Apoklepz
July 7th, 2006, 00:20
Yes, I can save and load without any problems. Yes, the problem only relies on the XMB and trying to get past that. Sorry, no clicking sounds...I've tried it.

Apoklepz
July 17th, 2006, 17:29
I suppose you could, but how would you flash your current firmware in the first place if you can't access any applications? The only way I've thought of is thru a UMD game save exploit, kinda like how GTA works homebrew for 2.60 firmware PSP's...If this could only be done through a 1.50 UMD (the only ones we can play on our half bricks right now) then I'm sure we could load any of the flash alternate homebrew applications and possibly restore our PSP's. But I do not know that this could be done yet...Somebody mentioned earlier in this thread of a possible WipeOut pure Exploit that supposedly Fanjita himself had talked about...But since everybody can play homebrew on 1.50, the urge to work on such an exploit is pointless....If only they knew how many bricks they could save and prevent at the same time.

Anger
July 17th, 2006, 19:16
the custom firmware concept is an idea that has been put to pratical use. it has a failsafe that allows you to trick your version into thinking its a 1.0 so you can run the 1.5 update. it is of no use to those who have already bricked there psp's but for someone who likes to protect there investment its a godsend - needless to say i am using it myself.

Apoklepz
July 17th, 2006, 19:29
Oh so what you're saying is I didn't care about messing up my "investment" in the first place when I altered my flash? If that's your point, you must take to consideration that I did indeed do my careful research before doing so...I didn't just go ahead and messed it up because I'm rich, snotty and could care less for it because I can buy another one....cause I'm really not...I have an average salary of $15 an hour and have to pay rent, car, power, water, cable ,food and college loans...so, it's not like I could just afford putting my PSP to waste in the first place....I however do own a second PSP, but that was a joint collaboration between one of my neighbours and me, so I didn't pay for it fully.

Please understand I'm not madly ranting off at you, I just want to make it clear that I just didn't go along and brick my PSP just for the Heck of it...I did my research first, and overlooking the steps, I still don't know what went wrong.

What I'm talking about is a second alternative of an exploit for 1.50 that hasn't yet been implemented...but it supposedly has been thought of, after the GTA exploit through game save method came out...I don't know...maybe it'll never be done, but I do consider it a possibility that'll help unbrick my PSP, since I can run a 1.50 or less UMD and save data too on my PSP.


however since the change of firmwares by sony the hackers have been concentrating on 2.x firmware hacks so maybe noones looking for a 1.5 hack anymore.

the eloader boots through the gta load screen(i think, ive never used it) but wipeout automatically loads its updates ( extra level packs) during its normal load screen(it takes forever when you have them all on there!!)
im guessing the update packs are the biggest chance of an exploit as the game is meant to run external data... which possibly could be swapped for an eloader

Hya everyone.

I just thought I'd bump my thread to share these news I found at Eurasia ... The Epsilon BIOS has been released, and it claims to unbrick your PSP's original flash...read on for the full skinny. BTW, for those of you wondering, I still don't have a modchip...It appears my contact got confused and fetched a PS2 modchip instead of a PSP's...I'm glad I hadn't payed for it yet...Oh, well...here's the article:

[source: Eurasia / EpsilonBios-UsersGuide.pdf]

Epsilon BIOS is a custom flash "replacement" for the Sony PSP which unleashes the full potential of your handheld, allowing you to both use homebrew software and run UMD ISO games from your Memory Stick on the latest firmware releases while also enjoying the impressive features built into the operating system such as RSS feeds, WMA support etc. Currently the 2.71 firmware release is supported. It is important to note that Epsilon BIOS is not standalone firmware replacement but more like a bootloader. It works using the dual-firmware system provided by the Undiluted Platinum hardware modification by loading when the PSP is initially powered on, then once running executes and "piggybacks" the real firmware stored in your PSP flash memory. Due to the way this works it is NOT possible to use Epsilon BIOS unless your PSP has an U.P. hardware modification installed.

Features

- Runs alongside 2.71 firmware, so you get all the features of 2.71 such as RSS feeds, web browser etc combined with the advantages of homebrew software and ISO loading.
- Allows execution of homebrew software in kernel mode, removing all limits previously in place while running homebrew on firmware versions above 1.50.
- Ultra reliable, near transparent UMD emulation allowing users to run their games from a Memory Stick with ease, including games which require 2.0+ firmware without rebuilding the ISO or relying on nasty hacks.
- Support for compressed ISO files for UMD emulation, allowing you to fit more games onto your Memory stick at one time.
- Built-in recovery menu which can be used to update your Epsilon BIOS installation or restore your PSP flash contents if it becomes "bricked".

Functional Description

As described above, Epsilon BIOS can be compared to a "bootloader". It is stored on the U.P. flash memory and executed when your PSP is powered on. Once Epsilon BIOS is running it loads and "piggybacks" the real firmware from the PSP flash. Currently only 2.71 firmware is supported, you must upgrade your PSP onboard firmware to 2.71 in order to use Epsilon BIOS. If you attempt to boot Epsilon BIOS with an unsupported firmware version you will be taken to the recovery menu where you can upgrade the PSP firmware. The great thing about Epsilon BIOS is that since the "bootloader" always runs before the real firmware we can apply whatever patches are necessary to disable - whatever protection Sony tries to add in the future, making a U.P. modified PSP using Epsilon BIOS very future proof.

With Epsilon BIOS you can run homebrew software (EBOOT files) directly from the OS main screen. Kernel mode applications are also supported meaning there are no limits when it comes to homebrew software. Both 1.00 and 1.50 style EBOOT's are supported.

UMD emulation is handled almost transparently. You do not need to launch a separate application in order to load your UMD games from the memory stick, all the ISO's you have stored on your Memory stick are listed alongside your homebrew applications in the "Game-Memory Stick" screen and executed from there. Copying new games to your Memory stick is easy, simply enable the USB connection and copy ISO's to the "ISOS" directory in the root of your memory stick. Please note that each time you change the contents of the ISOS directory a cache file containing the icons etc for each game must be updated, and this will cause a slight delay while viewing the "Game-Memory Stick"
screen.

Compressed ISO's are supported for UMD emulation using our own custom format, "Epsilon ZIP". Using the "Epsilon ZIP Tool" included in the archive you can convert UMD ISO files into EZIP files and vice versa. Simply copy the EZIP files into the same location as normal ISO files in order to play them.

Epsilon BIOS includes a recovery mode which can be used to update the PSP onboard firmware, restore a bricked PSP or upgrade your Epsilon BIOS installation. If there are any problems while booting then you will be presented with the recovery menu. To forcefully enter the recovery menu, hold SELECT+START when you power on the PSP.

Installation

Epsilon BIOS is broken into two distinct parts: the bootloader and the core. The bootloader is programmed to U.P. flash from the PC and is what actually takes control of the system when you first power on your PSP. The bootloader attempts to load the core installed in U.P. flash; if the core has not yet been installed or there is another problem you will be taken to the recovery menu. When you first program the Epsilon bootloader onto your U.P. you will need to install the core separately since it is not bundled inside the bootloader flash image. However, whenever an Epsilon BIOS core update is released you simply copy the update file onto your Memory Stick then use the recovery menu to update the core. This system is much safer and more user friendly than having to reprogram the U.P. flash from the PC each time you update which would be required if the bootloader and core were integrated.

Installing the Bootloader

1. Turn on the PSP while holding LEFT to enable U.P. programming mode
2. AFTER the PSP has turned on, connect the USB cable to the U.P.
3. Program the bootloader flash image (epsilonBootloader*.flash) to U.P using the flashing tool
4. Cold restart the PSP by cycling power

Installing/Updating the Epsilon BIOS Core

Updates and the initial installation of the Epsilon BIOS core are handled through the Epsilon recovery menu. To enter the recovery menu hold SELECT+START while you power on the PSP. The procedure to install/upgrade the BIOS is as follows:

1. Copy EBUPDATE.BIN to the root directory of your memory stick. This can be done via the
recovery menu by selecting "Memory Stick USB" or with a card reader, PSP XMB etc
2. Select "Update Epsilon BIOS", then hit X to confirm
3. Once the installation/update is complete the PSP will power off.

Notes Regarding Homebrew

As the majority of homebrew software currently available is designed to run on the 1.50 kernel we decided that for compatibility reasons it would be best to have Epsilon BIOS load the 1.50 kernel instead of 2.x when running homebrew software. This is possible since the Epsilon BIOS bootloader is actually based on the 1.50 firmware so when running homebrew software the kernel is loaded from U.P. flash rather than PSP onboard flash. The only known issue with this method relates to wireless network configuration - since the 1.50 kernel does not support WPA encryption you will need to configure your PSP to use WEP if you wish to use WIFI enabled homebrew software.

Recovery Menu

To forcefully enter the recovery menu hold SELECT+START while you power on the PSP. The Epsilon BIOS recovery menu from the 1.0 bootloader has the following menu selections:

1. Memory Stick USB – Enables the USB connection between the PSP and PC for transferring files. This is the same as the USB connection in the PSP XMB.
2. Update Epsilon BIOS – Installs an Epsilon BIOS core update from the memory stick. The update file must be named EBUPDATE.BIN and placed in the root directory of the memory stick.
3. Launch Firmware Updater – Launches an official Sony firmware updater EBOOT stored on the memory stick at /PSP/GAME/UPDATE/EBOOT.BIN. You may use this feature to both upgrade and downgrade your PSP onboard firmware version. Please take note first of the following important facts:

a. Epsilon BIOS releases are only compatible with certain firmware versions. If you flash your PSP to an unsupported version you will be taken to the recovery menu by the bootloader until such time as a supported firmware version is installed.
b. In order to downgrade your firmware certain files must be modified in your PSP onboard firmware so the official Sony updater *thinks* you have a very early firmware version installed. There are always risks involved with modifying your onboard firmware and such an action can be potentially hazardous to your data. Please note that when upgrading the firmware version no files need to be edited so this warning does not apply.

4. Restore onboard NAND – Used to “un-brick” a PSP by programming a known good flash dump (such as a dump of 1.0 or 1.50 firmware) to your PSP onboard NAND flash. The flash image must be a file called “nandImage.flash” in the root of the memory stick, in the same format used by the UP flasher tool (512bytes user + 16bytes extra for each page, interleaved).
5. Shutdown PSP – self-explanatory :)

FAQ

Q: Why do I get a 0x86660000 error when I try to launch a Sony firmware upgrade?
A: Epsilon BIOS blocks you from trying to install firmware versions that are not supported by the installed core. If you wish to upgrade to a new firmware, you might first need to upgrade Epsilon BIOS to a version which supports said firmware.
Q: From firmware 2.6 and up, PRX files are protected with a new encryption method. How did you figure out how to decrypt these files?
A: As most people will now be aware, the discovery of the 2.6 kmode exploit lead to decryption of modules using the new encryption method. However when we started working on this the kernel mode exploit was unknown so we took a different approach to reach our goal, one that doesn’t rely on exploits so should allow us to easily hack new firmware releases in the future once Sony changes the encryption method again. Here’s how we did it - warning: this is a bit technical, which unfortunately is required to give a proper answer. Since we couldn't get a dump of kernel memory from a PSP running the 2.6 firmware, the only way to figure out how to decrypt the 2.6 PRX files was to disassemble the IPL and see how this decrypted the files while the PSP is booting. Unfortunately, Sony used a clever trick in the 2.6 IPL to prevent hackers disassembling it. They read out some data from the reset vector and use it to decrypt the main portion of the IPL code. The problem here is that by the time we can run code on the PSP, any attempt to read out this data will be in vain as it gets scrambled inside the IPL. However, through some hardcore trickery we found a way to dump the data at the reset vector which enabled us to decrypt the main portion of the IPL code and then use this to figure out how the 2.6 PRX files were encrypted. The same encryption method and keys are used in 2.7 and 2.71, so when 2.7 came out we had this dumped and decrypted very quickly. There is nothing left now they can use to hide the IPL so when the 3.0 firmware eventually comes out its highly likely the encryption will have changed again but it shouldn’t take too long to figure it out. Sorry to give you the bad news Sony.. the hackers win another round, you cannot hide your firmware from our eyes anymore ;)

It's likely that there will eventually be a way to run an exploit on a different game - and it also seems likely that people looking for such an exploit would look in a game that lots of people have - so a v1.5-compatible game would be a likely choice.

However - it also seems likely that any exploit that included a way to fix your PSP would also need to have some sort of access to your XMB to set it up, or at least get it onto your memory stick.

I'd guess that your best bet is to look into the hardware unbricking methods - otherwise, you'll be waiting for an exploit to come along that might or might not help, and it looks like the odds are against you on that.

Hey thanks for the informative post, Mr. Fanjita. It's quite an honor for me to finally have your say about this in my thread.

I think with the way I'm sitting down money-wise right now, it's likely for me to be patient and wait for such an exploit....I recently got a new car and I've been forced to put my consumer hungry manners away for a long while...Thank god for emulation on my PC.

About my PSP...I'd like to add, that I do have access to the memory stick, but not directly through the XMB, of course...So, given that I can save and load data for 1.50 UMD games on my partial brick, is it possible to make an exploit of that kind? You know, a kind of exploit that would load through a game save....or even through one of those Wipeout Pure content Packs?

Also, it would be no problem at all for me to put the exploit to the memory stick, I recently purchased both the card adapter and the card dock adapter for a measily $10 U.S.

hey cant there be like an exploit to load dev hook? then you could emulate your firmware, then update then downgrade? cause from what i understand the eloader doesnt work for you?

Apoklepz
August 2nd, 2006, 19:24
Well yeah, eloader is not intended for 1.50 firmware which I have, and word is that Devhook is considered ilegal by Sony right now, so my chances are kinda slim for that part...I really don't know what could be done there.

apparently only devhook 0.43fix is illegal according to sony...
weird

August 2nd, 2006, 20:41
Yeah...What Sony doesn't understand is that both hackers and pirates alike will do whatever they want with the PSP until the day Sony stops pushing updates and allows official homebrew functionality...which will probably never happen.

that version may be the only one there after right now but it hasnt stopped ookm from removing devhook completly from the japanese site that usually hosts devhook. at least thats the way i read the news post. and if they find a reason to remove all devhooks they will - there requesting to speak to booster regarding this so i think devhooks future is in serious doubt.
