Downgrade 3.71M33 to 1.50 without pandora

[wraggster]

News/release from Samhain;694755:


This is how I've downgraded my FAT PSP with CF 3.71M33 to 1.50 Original FW:

* Copy the entire content of the attached file to PSP\GAME folder.
* Rename Original FW 1.50 file to UPDATE.PBP and copy it to PSP\GAME\UPDATE folder.
* In the Game menu launch "Update to X.Y.Z."
* Follow the onscreen instruction and it's done in a while.

I got a FAT PSP with motherboard prior to TA082. I've no responsibility if you damage your PSP with the above procedure.

Works on TA-079 and TA-082

Nice!

[pt9087]

Awsome! :thumbup:

[CaptainMorgan4]

Hey I'm currently bricked on 3.71 M33 and only can access the recovery menu, could I launch this from recovery and go back to 1.5?

[Anonymous D]

in theory yes to the above, but itd have to be put in the folder as sepcified by the recovery i forget whart thst is now.

[CaptainMorgan4]

So what your saying is if I rename this folder to "Recovery" and throw it in the GAME folder and put the 1.5 firmware in it and name it to UPDATE and then run the recovery from thing from the recovery menu it will work? Can someone here that knows for sure if it will work please tell me because I really don't want to go through the whole Pandora thing if this is a solution. I hate being BRICKED I want my PSP back!

[Nikolaos]

Who would want to downgrade from 3.71 M33 :D

[CaptainMorgan4]

People like me who bricked, and you know maybe a couple RARE people who like 1.5 kernal.

[240-185]

Me.

I used to launch some homebrews which don't work in 3.71M33. Most of them are emulators... Also PimpStreamer and IRShell.

Not the most important, eh?

[jak66]

People like me who bricked, and you know maybe a couple RARE people who like 1.5 kernal.

i think what you need to do is as above, then copy (not move) the eboot to the RECOVERY folder inside GAME

[ab88]

I thought noobs couldn't wait for their 3.71 M33 (More like demanded it to be done) :rolleyes:
Maybe this is a lesson to STFU next time, be patient and READ THE README (or the news post for that same matter)

Changes in 3.71 M33:
- Now uses 3.71
- VSH Menu is not longer launched using HOME key, but using SELECT now. This is to not interfere with the XMB function of home, which is now more useful in this firmware.
- Psp Slim: umdcache was allocating memory even when homebrew was launched, wasting memory that homebrew programs may want to use. Now umdcache module is stopped before it can allocate any memory, only in the case homebrew is launched. Also, memory is unprotected for user memory usage by M33 core (only when homebrew is launched). Developer, for a sample of how to use the extra memory, see the extra ram sample of the M33 sdk.
- Both version boot now from 3.XX ipl, and are independent of 1.50. The main installer will not install 1.50 kernel anymore. A 1.50 kernel addon for 3.71 M33 that will install inside 3.71 M33 will be released in a few days (for fat only)

[Sterist]

isn't this the normal downgrade process, but from the XMB instead of recovery ... ?

[DarthPaul]

Hm... we couldn't do this before?

Oh, thinking about it... no. Thanks! Awesome.

[jak66]

ahahaha, awesome...this is 'teh noobz' 3.52 downgrader, not a new one for 3.71 at all

[CaptainMorgan4]

Jak66 I'm not sure what your talking about could you elaborate? Ok I put this folder in my GAME folder after renaming it to RECOVERY. I then put the 1.5 firmware in there after renaming it to UPDATE. Then I put the new RECOVERY folder in my GAME folder and ran it. I got a black screen and nothing happened. So then I took the eboot from the old recovery folder (from 3.02 OE) and replaced it with the eboot that came with this downgrader. This time after running it it acted like it was going to work but then after I clicked X to accept the license it just gave me errors the whole time SO it didn't work. Lastly I then took the whole old RECOVERY folder and put THIS eboot that came with this file in there and I just got a black screen. SOMEONE HELP ME PLEASE I DON'T WANT TO DO PANDORA BECAUSE IT'LL TAKE ME AT LEAST A COUPLE DAYS TO GET ANOTHER PSP TO DO THE PROCEDURE. Please to whoever coded this project PLEASE make it runable through the recovery menu PLEASE I want my PSP back. Anyone else here have any ideas of how to get my PSP working again????

[240-185]

I switched back only because the kernel 1.50 takes a lot of time to develop. Even more when I know that D_A wants to unbrick first some customized PSPs.

He was so tough with all these noobs who couldn't wait for 3.71M33... But when they break their toys with some dumb customizing, they still must be served first? I don't get the point.

I always followed the updates of the custom firmwares, but here, it is the first time I switched to an anterior custom firmware...

[pspuser1993]

use pandoras battery to recover

[Broadus]

SWEET! Finally, a downgrader! I'm so tired of crappy 3.71 M33.
Thanks, Samhain! Though I haven't actually tried this downgrader yet...

[CaptainMorgan4]

Please anyone know how to get this to work through recovery menu, I'm bricked so please someone help me out. I can do Pandora but it will take me some time to get another homebrew PSP to get it to work. Question though guys, when I do the Pandora procedure will I have to delete the stuff off it or can I just make it a magic stick with my stuff on it and then just delete the Pandora stuff manually when I'm done?

[cyclonus002]

Works perfectly...

[Broadus]

This worked perfectly! Thanks.
If you want to make your memory stick a magic stick, CaptainMorgan4, just take all of your stuff off, follow the normal format procedures that Pandora so desires, then put all your stuff back on.

[CaptainMorgan4]

Yeah I'm getting my friends PSP tomorrow so hopefully I'll be back.

[pedalsLFC]

it ses the game could not be started 80020148

[pedalsLFC]

me so i can get a custom firmware i dont hav 1

[Excko]

I'm very very happy to say that this worked like a charm.

[JPJunkie]

I don't have a clue what my motherboard is how do I tell

BTW I no how to tell if its TA-082

[XxunknowxX]

it works nice and i used a regular mother board didnt need to have a TA-082

[JPJunkie]

So does this work on any psp?

[Null Replica]

Thanks Man! I really needed this since i don't have a pandora. been a big help dude!:thumbup:

[CaptainMorgan4]

Hey is there anyone here that has experience with the Pandora procedure? I have a working 3.52 M33 PSP and my bricked 3.71 M33 PSP and I tried twice using the Pandora steps and something just wasn't working each time. I would appreciate it if someone could help me and maybe walk me through it since obviously I couldn't get it to work last night. I meet all the requirements so PLEASE anyone that can find it in they're hearts please PM me or talk to me on here.

If it did not boot then your ipl is not bootable.

If you live in england i could unbrick it for you.

[Sterist]

For those who dont feel like waiting for your battery to charge to 75%, hold L + Triangle from gameboot till the disclaimer

I do not recommend if the XMB reads your battery as 20% or lower. (even though the entire process takes about 0.5% to 2%, depending on your screen brightness)

[CaptainMorgan4]

No I don't live in england, no there was this one step that wouldn't go right so I think that was the problem. I'm currently getting help from Darth Paul so.

[xzeldafan92x]

Thanks so much, man!

[ForgotenDynasty]

Rename Original FW 1.50 file to UPDATE.PBP and copy it to PSP\GAME\UPDATE folder.
where can i get this

[CaptainMorgan4]

They have firmware downloads at psp-hacks.com and I'm sure if you searched you could find one on here some where.

[sebastien1990]

can u help me
wen i started the update it showed me a message saying the game could not be started
get bak to me asap

[poofacetherisen]

you also cant use some plugins (most)

[CaptainMorgan4]

*!!PLEASE someone report this bug!!*
The 4gb Sandisk Ruby Red and quite possibly all the 4gb memory sticks (need further testing) are not compatable to be made into Magic Pandora Memory Sticks.

[camcorderdoctor]

I can confirm that 4g memory sticks will NOT work!(using pandora installer) When you try to re-partition and format the stick it goes right into the set-up of 1.5 firm and then wants to set the msipl file, when it does and exits it says there is no memory stick - this is wrong, it should tell you to re-boot the psp at the end of format -- 1g and under (as long as it's a pro stick) WILL work.

[CaptainMorgan4]

I think the 2gigs work I heard that somewhere, so yeah looks like 2gig and under WORK.

[i3ipolar]

exellent i been looking all day for just such a program

Have you tried using the Windows tools for formatting the stick and writing the IPL?

[Ratatella]

Hey Ya'll,

Don't know or I'll help people with this one,.. but it did make me verry happy. :D

I wrote a readme for how to recover a bricked 3.71 M33 PSP FAT from inside the recovery mode.
(back to 1.50)

EDIT:
link where you can download downgrader provided by Samhain incl. my unofficial readme
http://www.megaupload.com/?d=PZSCNT8S


peace.

[CaptainMorgan4]

This could unbrick me but I'm gettin the 1gig today from my cousin so I'll be having Pandora ready today, but this being your first post makes me suspicious.

edit: Looks ok now that I looked at it but I will try this before Pandora today, if this works I'm going to be so pissed because this is what I was looking for, for days!

[Ratatella]

joow CaptainMorgan4,

I'm sorry if I make you pissed :confused:
Only posting it for people who would read and need it.
I'm not the whole day on the net looking for people who have problems with there psp.
I just found this trick out myself after hours trying and searching.
It made me very happy cause it unbricked my bricked 3.71 M33 psp FAT.
So I thought... let's share the knowledge!!

Well anywayz,.. hope you unbrick your psp... and can be happy again. :)

Peace Bro..

im getting "the game could not be started" help please i know others have had this problem too.

[bmasti]

when i try to downgrade my 3.71 to 1.5 its showing me this game can not be play error can any one tell me whats wrong ?

[xxhiroshi21xx]

Are you running custom firmware? Or official sony firmware?

Gearing to downgrade mine from 3.71M33, only because IRShell is incompatible with 3.71, and I enjoyed running my games from my PC.

LoL it works, nice. Knew it worked when it auto-booted into my UMD. XD

[kjetil1991]

im going back to 3.52 no flash themes working for 3.71 =( sorry sony i dont like your themes LOL! i think 3.71 was meant only for the slim the fat is not doing good on 3.71 it becoms boring =(

[xxhiroshi21xx]

Yeah..successfully downgraded, and upgraded to 3.52M33-4 no problems at all. Yeah, it would have been better honestly, if I had a larger memory card, being only at 1GB cuts me kind of short, so I gotta run most of my games from USBHOSTFS, and load my homebrew from the card.

[Unlogik]

Hi would it be possible to downgrade my PSP thats running 3.52 official with this trick? Can any1 answer this realyl quickly please because Im about to buy a Pandora battery

[SpooForBrains]

Hi would it be possible to downgrade my PSP thats running 3.52 official with this trick? Can any1 answer this realyl quickly please because Im about to buy a Pandora battery

If you're on 3.52 official then a pandora's battery and magic memory stick are the only method that you can use to downgrade.

Don't buy a pandora's battery. Just get a regular battery (this one (http://www.amazon.co.uk/gp/product/B000A6CD04?ie=UTF8&tag=fanjitasplace-21&link_code=as3&camp=2506&creative=9298&creativeASIN=B000A6CD04) is cheap and confirmed to be compatible) and convert it yourself. It's a simple process.

[Unlogik]

and how do I do that? the soldering method? if so, I havent got ANY soldering skills and I havent even got a soldering iron.
Any other way m8?

[SpooForBrains]

http://www.noobz.eu/joomla/news/unbricker-for-all-firmwares.html

That link will tell you all about Pandora. The readme included with the download includes instructions for using the tools. It requires no soldering. All it requires:

1. a homebrew capable PSP*,
2. a machine running Windows 2000, XP or Vista,
3. an official sony "fat" battery (ie. not the one shipped with the slim) or the one I linked to,
4. A memory stick that's larger than 32 and smaller than 8GB. A 512MB is ideal, and can be bought from picstop.co.uk very cheaply.

* Why do you need a homebrew capable PSP? Because you need to create the files necessary to make the memory stick, which will end up containing Sony copyright code, so distributing an already created one is illegal.

If you don't have or have access to a homebrew capable PSP, this page:

http://www.noobz.eu/joomla/news/information-for-ebay-buyers.html

has links to pages where you can find a volunteer who will help you.

SOMEONE HELP MEE!!!!…..i installed 3.71M33 on my fat psp, and it worked fine. And then i installed the 1.50 kernel thing, and it worked fine. But after, like and idiot, i tried insalling a theme with slash n flash. And now my psp is messed up. SOMEONE HELP!!!!

[banner362]

I only made a backup of my flash before i installed the 1.50 kernel thing. So im guessing i need a backup flash of a psp with 3.71m33 AND 1.50 kernel. PLZ REPLY!!! I CANT USE MY PSP

[Saracchini]

You have an Pandora battery or access Recovery Menu ?
If you have why you dont reinstall 1.50 then 3.52 M33 and after 3.71 M33 +add-on ?
Or if you have a backuped nand of your PSP when it was 3.71 M33 just reflash it and install 1.50 add-on again.
Flashing the nand of another PSP can give you serious problems .

Hey banner362,

I had exactly the same problem as you and found a trick to fix it.

download this AND READ the readme I wrote myself.

http://www.megaupload.com/?d=PZSCNT8S

that should downgrade your psp back to 1.50. From there you can go to a CFW again.

goodluck.

yes, you need to download the 1.5 firmware eboot, name it 150.PBP and put it in the root of the memory stick.

Hi, I'm new to this and was just wondering if someone could help me out. I've had a psp since the day it launched in the U.K and have been able to maintain the 1.50 firmware. However the latest Roms won't play with Devhook, fastloader etc..

So I upgraded to that new custom 3.51. All my roms work fine, but before, whenever I restarted the psp it would always revert back to 1.50. This time it seems stuck on 3.51!!

Not a problem as it still plays all my games, however I was wondering if someone could explain to me what has actually happened to my psp, and if I have lost my 1.50 firmware forever????

Thanks.

nice these forums use "newbie" as a title that's funny, my site just drops an article on the main page called "newbalicious"

Anyhow I'll look about.

News/release from Samhain;694755:


This is how I've downgraded my FAT PSP with CF 3.71M33 to 1.50 Original FW:

* Copy the entire content of the attached file to PSP\GAME folder.
* Rename Original FW 1.50 file to UPDATE.PBP and copy it to PSP\GAME\UPDATE folder.
* In the Game menu launch "Update to X.Y.Z."
* Follow the onscreen instruction and it's done in a while.

I got a FAT PSP with motherboard prior to TA082. I've no responsibility if you damage your PSP with the above procedure.

Works on TA-079 and TA-082

Dude! i've breaked my psp slim
but thank tou god that i already had pandora slim and magic memory stick and had nund-dump.bin file

i wanted to downgrade 3.71 M33-4 to 1.50 kernel

i've ned this because i have clients who want versions like 2.60 and e.t.c.

but my MMS and Pandora slim battery only installs 3.71 M33-2

Could this be used to downgrade from 3.90 M33 to 1.50? Maybe replacing the 3.71 files with the 3.90 files? Maybe? In theory?

[SkyscraperXD]

@TazJGC
The answer: NO. Sony changed the NIDs and stuff of all the homebrews and etc, so the devs needs to make a new downgrader.

EDIT: Haha... very funny. Error code DADADADA. Apparently, my psp (TA-82) think this is a offical update or something. What now?

I made a pandora last night haha!
