PSP Downgrader - Downdate Final Version For v2.50/v2.60 PSP Firmware

[wraggster]

The Downgrader for v2.5 and v2.6 PSP Consoles by Dark_Alex, Mathieulh, and Yoshihiro has been updated to a Final working version. Remember that unless you know and are confident of what you are doing then do not use this downgrader,

Heres whats new in this release:
- Added a checking for the AC adaptor. Now it's necessary in order to begin the downgrade.

- Removed the logs, they could cause problems with people with 32 MB memsticks.

Also i want to explain a couple of things:

- The "Disc cannot be read" problem. This is caused because the hardware restart that the downdater does, doesn't restart the umd device. There were a more proper way to reinit the psp, but it wasn't working in this exploit. Not a big problem really, since after you restart manually the psp, the problem is gone.

- DO NOT USE dumps of other firmwares. As important as the files, is the IPL (Initial Program Loader), which is written by a library of the Sony 1.50 updater, that is hardcoded to write the 1.50 IPL.heres a guide that Freeplay wrote:
Here, have a guide:

FOR 2.50/2.60:

Get the appropriate ZIP file from the very first post in this thread. password -

I_Use_It_At_My_Own_Risk

(copy and past, password is case sensitive)

There should be an EBOOT.PBP file in the ZIP file.

On your memory stick, go to PSP, then GAME. Make a folder called DOWNDATERTEST.

Put the EBOOT.PBP file in DOWNDATERTEST.

If you have a 1.50 dump, copy the DOWNDATER folder to the TOP LEVEL of your memory stick.

IF YOU DO NOT HAVE A DUMP, DO NOT EVEN ATTEMPT TO RUN THIS PROGRAM. YOU MAY BRICK YOUR PSP.

For example, if your memory stick is O:\, copy it there.

This folder should contain two folders and two files:
DOWNDATER\DUMP\ (containing the 1.50 dump)
DOWNDATER\PRX\ (containing the 1.50 UPDATE .PRX files)
DOWNDATER\inputfl.bin
DOWNDATER\outputfl.bin

IF THIS IS ALL OK, YOU SHOULD BE SET:
* The two files and two folders mentioned above
* PSP\GAME\DOWNDATERTEST\EB OOT.PBP
* eLoader
* GTA
* A PSP THAT DID NOT COME WITH 2.60 PRE-INSTALLED

Now... Go into GTA, go into eLoader, and run "DOWNDATER TEST".

The Memory Stick light will blink for about 2-3 minutes.

Afterwards, your PSP should reboot.

You should get the blue "Reset to defaults" screen. Press O.

The PSP will reboot again. You will have to define basic settings again.

You might notice a "Disc could not be read" error.

If you do, take the battery out, put it back in, and reboot.

Good luck, folks!Make sure you dont have a PSP version TA-082 which can easily be spotted by opening the UMD Drive and looking in the top-right corner for the text "IC1003" If you see those digits you cannot downgrade or even use the PSP Modchip.

As always my adivce is do not use if your not 100% sure and confident

[dtothabreezy]

for any body that hasnt done it yet the succes rates about a 100% but still do it at your own risk

[YourStillWithMe]

how would you know that? its not like you did it more than once. . .? Anywho this downgrader looks ultra sketchy my friends if i was at 2.50 or 2.60 i probably still would not try it. the risk is definitely higher than the 2.00 version thats pretty clear

[acn010]

good :)

[gunntims0103]

well i ahd a successful downgrade so im good:D

Sony is going to release a firmweare update mark my words in less than a week

I agree about sony and a new firmware...I say before the months up and the upgrade is gonna be crappy!

[\/oid]

the final version woked 4 me:)
no problems at all...

[Bubby_the_Tour_G]

Will this work fine on a 32mb memory stick? And also, I need someone to completely walk me through this, and can I use the firmware dump from Catfish from the original PSP-hacks downgrader pack?

And one more thing? Do I delete all of my savegames too and only leave the gta eloader save, or can I keep my gta saves in because all I have is a 32mb stick!!!

[F9zDark]

I'll give it a shot with my 1.5. It has about 5 -2.0->1.5 downgrades under its belt(after being 1.5 by default).

Let you know the results.

back them up on pc...... then put them back once ur done downgrading

[mike03$$$]

can someone teach me and help with the links to this dump and the output, input bin things

[imdickie]

I have tried the noted password on the rar'd files in every iteration I could possibly think of including a cut an paste. Did the password change?

[stotheamuel]

why would sony update? it doesnt work on 2.7 so there would be no point... unless... they updated with some pretty impressive stuff?

[dtothabreezy]

the way i did it was just download the kit from pspupdates or hacks its one of those and put those files on the root of the memory stick start up gta

and lit it do its thing make sure its plugged in and theres gonna be a minute or 2 when u dont know wats goin on itll reboot after its done so dont turn it off if you get disk read error take out battery and put it back in (i got disk read error and that worked)

yes it will work on 32 meg make sure u reformat the memory stick then put everything on thatll make sure you have enough space and as an extra security percouation i went to systems and rest default:D hope it works for every body and i hope this helps

[Bubby_the_Tour_G]

back them up on pc...... then put them back once ur done downgrading

That doesn't really help me at all... :(

I mean do I leave only the eloader save, and I also need to know about my other questions too.

[xiringu]

yeah, I think Sony needs to add impressive stuff to a new FW to make people want it.

just a stupid video/music/web browser new option won't make anyone want to lose the homebrew

[Gamer8174]

This downgrader does indeed work. I now finally have a 1.5! But, this cant be stressed enough, make sure you understand every step of the instructions before attempting this.

[Bubby_the_Tour_G]

I need to be sure that the final version of the downgrader does not write any logs on the memory stick, because 32mb is all i have :(

[dtothabreezy]

it writes logs but i have a 32 meg 2 and after i was done i just reformated my memory stick and it was good as new jus make sure all you have on it is eloader and the downgrader and ill hope youll be fine

[no_pulse]

I managed to downgrade successfully with the previous version, the success rate does seem to be reasonably high although there were a few bricked PSPs.

Thanks to all the guys which worked on the downgrader and to Blazed247 for his instructions(page 17 of previous release's thread) it helped me a lot!!

[eliteflyer]

I am kind of new here and i really need firmware version 1.5 for my PSP. I have downloaded the 'downdater_final.rar' file and i was reading the read me and came accross, 'needs 1.5 dump'. I don't know anybody who has a 1.5!! Although could i download this 'http://www.psp-hacks.com/file/9' and use this instead of finding someone who has 1.5. Or am i just being really dumb and i don't need any of this?? Thanks for the help.

[RetroGoth]

is anyone ever going to help us factory 2.6 users? it's not fair you are ignoring us.

[no_pulse]

Its not that they're ignoring you its that its not possible for them to help you at the moment. Just be patient and wait for an eloader with full kernel access to be released.

just drag and drop all the files from the downgrader

[eliteflyer]

So i don't need to find anyone who really has a 1.5 and copy thier files??

[no_pulse]

So i don't need to find anyone who really has a 1.5 and copy thier files??

[mr_nick666]

I think the second hand PSP market is going to speed up once again now! - No more scrabbling for 1.5s ;)

Its like the tooth fairy... Everyone says shes just a myth and then you see her! :o (or something like that! - And they said they didnt think a downgrader was possible!) :D

[gotmilk0112]

so this is what i do:

1.unzip the RAR file

2.put the "DOWNDATER" folder in the root of my mem stick

3.put the DOWNDATERTEST folder in my GAME folder

4. run the program

is the "DOWNDATER" folder the same folder as if the person with 1.50 copied it?

[acn010]

yup

[gotmilk0112]

ok

[xsimmonsx]

Ok silly question, sorry if its been asked with in this thread.

I know most of my stuff when it comes to psp, I downgraded to 1.5 from 2.0.

My young ones got my old psp which was 2.5 from the box, yet its been upgraded to 2.6. So will this work seeing as its been upgraded to 2.6?, as I see on various forums that people are saying a 'factory set 2.5/2.6' wont work, which is what this started out as.

[MHB_1990]

Too bad for me I've upgraded my psp to 2.71 and I'm stuck the bad thing that the downgraders doesn't come in time.

[mike03$$$]

sucess i ran up the wall it worked i had used the auto installer with files already in it

mine came as 2.5, but i never upgraded to 2.6....

i reckon you are probably ok to downgrade with this version.... although i'd check the number inside the UMD drive inside if i were you (mine says ic6001 - apparently if it ends in "3" you cant downgrade)

[Decarbonizer]

ok so i downloaded it but get a password
i cant find it so could someone help me here :)

[Ari]

god, I feel like an idiot now! I just upgraded to 2.7 from 2.6 a few weeks ago...

I_USE_AT_MY_OWN_RISKS

Also great downgrader, I did it yesterday with release 5 and I'm loving 1.5.

[F9zDark]

What I'd like to know is, why is TA-082 PSPs unable to downgrade? Has anyone figured this out yet?

I really hope Sony doesn't start this trend in future PSP production lines; making it impossible to run homebrew due to the motherboard rather than software means.

To go back to what I was saying earlier about testing, I haven't had a chance yet. Will do though once I have a few moments to myself. (Using the PSP to entertain some family members with music via the Nyko Theater Experience)

[DCtest]

ok so i downloaded it but get a password
i cant find it so could someone help me here :)

The password has been changed for downdater_final.rar

Have a look there http://www.sonyxteam.com

Thank all of the PSP community for this great "utility"
and for the professional help in drowngrading.
Thank you very much.

Great Job !

[chaos-is-me]

I havn't written in these forums much recently with all the stuff that's going on with my band at the moment but I saw this and just had to test it out..

It worked! OMG I have longed for a 1.5 PSP ever since I got into homebrew. Finally I have one!

It was pretty nerve racking but it went smoothly. Can't wait to test out some homebrew without having to boot up GTA:LCS first!

Thanks to the people behind this and to DCEMU for letting me know of it's exsistance! ^_^

[Bubby_the_Tour_G]

No one has answered my question yet, I wanted to know if this final release of the downgrader does not write anything onto the memory stick and it works 100%, as I only have a 32mb stick :(

[**1_Man_Matrix**]

This is very cool. Downgraded without a hitch.

1 question though, because I was on 2.6 for so, so long I got out of touch with what's available on 1.5, and all my UMD's are 2.5/2.6's.
I know what Devhook does, and I'm learning up on it. Just 1 thing...

How would I go about getting my copy of Syphon Filter to work on my new 1.5? Nothing dodgy, I own an American UMD of it, I just want to boot it. I know that 2.5 games can be booted on a 1.5...

So anyone, got a SF-DM on 1.5 success story? :D

Thanks all

[Kramer]

it doesnt write anything onto the stick but it does not work 100% no downgrader ever will

[gotmilk0112]

i hope my PSP dont brick. crossing every body part that i can cross xD

Syphon Filter UMD works great with Devhook. It'll be hard to find a UMD that doesn't.

Kramer: It does write (1KB) logs to the memory stick whenever an operation is executed.. it generates quite a few, but much less than any memory stick should have free. The main deal is that it works perfectly. ;)

[Bubby_the_Tour_G]

Kramer: It does write (1KB) logs to the memory stick whenever an operation is executed.. it generates quite a few, but much less than any memory stick should have free. The main deal is that it works perfectly. ;)

Well ok... but I mean in comparison to the beta...
How many logs do they both write in comparison to each other? Does the beta write a shitload and the final write, maybe a few kb?

I ask this because I don't wanna end up with a $200 paperweight just because I only had a 32mb dinky stick... I don't have a problem with formatting the ms, but i just want to be safe.

[phazi]

i think some one asked this but why dosnt it work and will there ever be a way for a new psp that comes with 2.6 to downgrade or no chance at all

[kcc86]

"- Removed the logs, they could cause problems with people with 32 MB memsticks."


I'm not sure what that means, but I successfully used the beta version of the downgrader, so my question is, what kind of problems will the logs cause to 32mb sticks? Does it cause problems with the memory stick or with the psp? I should have just waited for the final release cause I'm all paranoid now...

[**1_Man_Matrix**]

Awesome! Thanks heaps, sounds like a very well made app :)

[F9zDark]

Worked beautifully. Absolutely no problems.

I started with a 1.50 PSP, made my own 1.50 dump, then updated to 2.60. Then downgraded to 1.50. Quite a marvelous feat.

Now this got me thinking... Anyone who has a 1.0 and tried the 'downgrader' for that(the one that only works on the system it made the dump from)... I wonder if that can be used in conjunction with this or the 2.0 downgrader.

[kschewe]

I read that people where downgrading their factory 2.6 psp successfully to 1.5. Anyone on here try? I bought mine used and I am assuming it was 2.6 factory. I dont think there is a way to tell

[MUDD]

damn i feel so stupid asking this ,

i have a psp that i updated to 2.60
can i use this downgrader ?

from what i have read ,the answer is no
but now im reading these comments
and im not sure anymore .hope beyond
hope that im missreading the readme
wrong and i can.

you know i want to so bad .but if i cant
thats cool to .wont sleep till i know
for sure ,god aint this great!

[Sharkey]

Yes you can downgrade.
You pretty much have to update first if you had anything below a 2.5 to use this anyway.

As long as you didn't buy a 2.6 version psp your good to go.

One of my psps is a 2.01, I missed downgrading last time by one small update so I have been looking forward to this.
Odd that the device hook almost coincided with the release of this, someone loves us.

The password listed on the front page didn't work for me btw, I'm not bothered because I have the beta.
Just a fyi, is it because of the caps?

[johnston829x]

what is a 1.5 dump??? and is it ok if i have ic6001 .....i updated from 2.0 also

[**1_Man_Matrix**]

what is a 1.5 dump??? and is it ok if i have ic6001 .....i updated from 2.0 also

I'm no Charles Babbage (That guy would have rocked the PSP scene with a Homebrew Abbicus app).
But I believe it's the raw files that make up the 1.5 update... It's a 'dump' of the update and what's in it... Sound alright?

cheers :D

so should i do it?

[MUDD]

ahh ok i see thanks Sharkey,after reading
your help i had another look at the readme
and now i can see what it says clearly .

if its still the factory set you cant ,but mine
was updated to 2.60 so im good .
ok yeah i see it now .strange how i
missunderstood it so completly maybe
my mind just couldnt grasp the possibility .

EVERYONE IS GREAT .I LOVE YOU ALL
(stop laghing damn it these are real tears)

[stotheamuel]

hahaha thanks to this baby... (before it gets big and well know and obvious) im going to buy 5 psps... 2.6 while i still can (1000 dollars) then im going to downgrade.. and sell them for 300 dollars... thats 500 dollar profit

[firestorm]

PSP-1000, FW2.5 JP (factory)... will this work or do i need to update to 2.6 (i read something bout factory fw = bad)

[**1_Man_Matrix**]

so should i do it?

Well, you will have to if you are thinking of using the downgrader. After all, your trying to downgrade to 1.5, so it will need the 'dump'ed files from it.

I'm not sure about all the legal mumbo jumbo and I don't want to step on any toes, but you can pull one off a PSP that has 1.5 installed, you can download the eboot and do it yourself, or I think there's copies on the net already dumped, but like I said, I dunno if that is ok to do, morally and such.

Anyway, don't attempt the downgrader until you have it. Or it will look for the 1.5 dump... Not find the 1.5 dump... Then roll over and play dead, and your PSP with it. :(

Have fun! :D

[ryan_rocks29]

so should i do it?
I say if you know exactly what your are doing (not a newbie) and have the 1.50 dump, go for it like I did. If you don't know exactly what to do, don't try and wait for the new eLoader. This is just my opinion so if you are very desperate, go ahead and downgrade.

[Mr. Shizzy]

I'll try on my friends 2.6 and get back with the results. Man, if it bricks her PSP she is gonna kill me..

You don't need the EBOOT, you need the 1.5 firmware 'dump' which is all the files in the EBOOT. You can find the firmware dumps from some sites such as psp-hacks.

First, you make the folder DOWNDATER in your GAME folder, put the EBOOT in there. Then, you copy the DOWNDATER folder to the root of your memory stick. Put the firmware dump files in the DOWNDATER folder on the root of your memory stick and your all set.

[MUDD]

thats all i needed to hear ryan_rocks29 ty and im now a proud owner of a 1.5 .very fast very clean .
fubed up i couldnt sleep till i had this done ,so thanks for the fast reply .now i can go to bed at 2 in the morn and get up in a few hours and go to work a very happy man ,

thanks for everyones help and thank you thank you for being so fast to help ,i hope i can be as helpful to others some day ,

[Sterist]

if yall are wondering why sony would want to release another update, it's because sony didnt know about that exploit till now, so apon the event that another unpatched savedata exploit or wutever is found, it will still be usable. there is no extra security to block it in 2.70/1

My Europe PSP 1004K was in the begining version 2.01
and i uppgraded it in december last year to 2.6 could i downgrade it, if could somebody tell me where to find the files from the 1.5... Please... Someone

Yup!!!

i think go to psp-hack.com and download the 1.5 firmware...

[dilbert]

well i ahd a successful downgrade so im good:D

hi mate. i tried downloading the .rar file and extract it with this pw= I_USE_AT_MY_OWN_RISKS

its giving me an error message. and the files isnt there. ??

[scottyboynow]

does anyone have a ZIP file of it

Do I Need A 1.5 Psp To Get The Downdater Folder?

[caseyhalone]

" I_Use_It_At_My_Own_Risk " IS THE PASSWORD

ITS NOT IN ALL CAPS LIKE THE FIRST POST SAYS

[razero.we]

It worked!!! Its fu**ing unbelivable!

[cyclonus002]

My psp was 2.5 and I upgraded to 2.6 would I be a candidate for a fairly successfull downgrade?

[KriMe]

Where would someone begin to look for the "Downdater" files/folder if they did not have access to a 1.5 Psp?

[Bubby_the_Tour_G]

I would like to know how much space the FINAL version of the downgrader takes up and how much free space is left on the memory stick as I only have a 32mb

I already have the neccessary dumps and files & shit, I just need that question answered before I can go on.

[123]

I want to downgrade my 2.6 but I don't know anyone who has a 1.5 PSP. All of my friends have 2.71 PSP's. Also I have one question why is it against the law to put the downdater file on the web sony is already giving it out in the 1.5 update.

[eliteflyer]

It would be really helpfull if someone could make a step by step video tut! That would make it soo much easier for people like me who don't know much about the PSP :)

And for the people looking for a 1.5 dump and who do not have access to a 1.5 PSP, the final.rar version already has it. DOWNDATER_FINAL>DOWNDATER. Hope this helps :)

[The_It]

where can I find a 1.50 firmware dump to use in this downgrader? The final version at the beginning of this forum doesn't have the downdater folder in it.

[cyclonus002]

The downdater folder is 18kb is this right? Do I even need the actual 1.5 firmware dump folders or just the downdater and downdater test folders?

[The_It]

Can someone tell me how to install the dump files from http://www.psp-hacks.com/file/8 to my psp? I neet to know where to put all of these files, like where to put the prx files.

[chaos-is-me]

People people people! Instead of being lazy and asking all these questions just look it up for yourself. That's what I did, that's what everyone else has done.

I will help you out by saying to get this downgrade off psp-hacks as it includes the DOWNDATER folder.

[d3v1l]

ANYONE WANTING THE COMPLETE PACKAGE TO DOWNGRADE, PM me.. i made a folder for my friend, all u need is a memory stick with eloader on it ,n my rar, then ur all set! my friend had a factory 2.5 , n now its a 1.5:D pm me for the rar..

AmI being ignored here? please help

[The_It]

Ok... how do I use the downgrader from http://www.psp-hacks.com/file/598 . do you just drag the downdatertest file to the games section and downdader to the root of the memory card? And is it bad if there are any extra files in the downdater folder? there are a lot of extra files without file extensions in the rar file.

[Elsid]

great news for the 2.5 and 2.6 users

Not that there is any reason at the moment for me to do this, but is it possible to install the fanjita eloader into my psp (devhook) 2.5? after devhook is launched? (and get it to work of course)

does anyone know if the downgrader from this website will work perfectly if you do everything correctly?

[Teuras]

Where can I get the files from 1.5 (because I don't know anyone who has 1.5 and could do it...)

I mean the DOWNDATER folder and those...

[gotmilk0112]

it comes with it. the "DOWNDATER" folder is the sam thing as if a 1.50 user made it.

[gotmilk0112]

does anyone know if the downgrader from this website will work perfectly if you do everything correctly?

out of 535 people who did it there were only 3 bricks, 1st one was because power was too low, the 2nd was because of not enough mem stick space and the 3rd one i dont know.

[Teuras]

it comes with it. the "DOWNDATER" folder is the sam thing as if a 1.50 user made it.in the "src" folder? What do I have to change in it? The README file confused me...

(I have FW 2.6)

[KriMe]

I wanna do it but im scared :-( I dont wanna $200 paperweight. I think im gonna do it when i get home, Ill video it so you people can see how to do it...or how not to do it if i mess up. ;-) Any advice?

[Forsak3n]

Ok i need a bit of help...
Can i use my 32 mb

Next
i need a complete walkthrough of each little step to do.
I have 2.6 FW, and I want a walkthrough, because the one given isn't exactly promising to me.

[Samball91]

yeah, i cant see my numbers for my PSP in the top right corner. Is there any other way so i dont brick my psp? If it bricks i might explode...

ADD:

would it be possible to use another FW and rename it so the PSP is flashed with a 1.0?

[fistikuffs]

OH YEAH!!! I just did it, I have a 1.5 PSP!! Homebrew here i come!!!!

[Shilo]

No more crappy 2.5! I got a 1.5 PSP now :) I'm happy :D

[cyclonus002]

Ok I'm a bit confused. I can see two slightly different versions of tutorial. Do I need to put the prx files and the 1.5 dump in the downdater folder or is the thing all ready to go? Its 18kb just to be sure...please someone let me know...

[Forsak3n]

i know what you mean, there isnt a clear tutorial of what to do, we need steps.

[fistikuffs]

i'll post later on exactly how i did it maybe it might help you guys

[buffy]

Could someone please post a few pics of how it needs to set up on memory stick , this would make it clear for everyone as i read a few post of how it needs to be setup and there are a few differance's in what they say.

thanks in advance

[r00t]

I have a few questions mates. I have a 2.5 PSP. I noticed in the read-me it says "A PSP THAT DID NOT COME WITH 2.60 PRE-INSTALLED" Now what I wanna know is, is this gonna work with 2.5.

Sorry if this question has been asked one hundred times before but i'd rather find out through you guys that through myself.

Cheers!

[D0N]

You are going to have to upgrade to 2.60 and then downgrade. Make sure your PSP hasnt got a TA-082 motherboard

[r00t]

So, upgrade from version 2.5 to version 2.6 then, use the downgrader? Also, I checked my motherboard make, the code i see is; R10-1. So im guessing, i'm all ok? Also...another thing, where can I find a 2.6 firmware update file and a 1.5 dump? I'm sorry once again if you've awnsered these questions alot already..

[borikua_rocks]

You are going to have to upgrade to 2.60 and then downgrade. Make sure your PSP hasnt got a TA-082 motherboard

Im actually having some trouble with finding this out. See mines actually comes with numbers, but there not as easy to see as it shows in the video. its actually behind the UMD Disc holder. You can only see the top half of the numbers. Those this pose a problem? In the video, there numbers are easily shown on the top right corner. Mines is on the left hand corner, hidden behind some metal works for the UMD's.

[bullhead]

that was the same for me, you can only see half of the words. It worked like a charm for me. (For IC6001)

I Can Only Get The Files With Just Empty Folders? Any One Help?

[grit]

I'm a happy black psp 1.50 (2.00 -> 1.50) owner.
But those white ones do look sexy, don't they? ;)

So I want a white one but not 2.60 (2.60 is almost the same as a bricked one, for me).

First thing in the morning I went to the store (Portugal), checked that it wasn't a TA-082 board, Checked the letter on the box (it is has an "I", reported as 2.50).
Got home, charged it a bit, power up, saw the RSS icon and thought "NO!!!, It's a factory 2.60.." :mad:

First UMD it ran : GTA.
Second app: Fanjita's magic stuff.
And then : Alex breakthrou code..

Result: A brand new white psp FW 1.50!!:D :D

Thanks Alex!!

So, it worked perfectly on a factory 2.60. Eat that Sony!


@ Sony: Trow the towel to the floor! You can not win this battle. And I doesn't need to be a war.
Open up that FW. Stop breaking the nice piece of hardware you created. You will not regrát.
And you own Alex one: If it wasn't for the Alex downgrader I wouln'd buy a second PSP in the first place..

NO, I will not upgrade for the PS1 emu.. :p

Yes upgrade from version 2.5 to version 2.6 then use the downgrader. Yep the code is alright. For the 2.60 update go to psp-hacks.com and go to downloads section then firmware and look for it in there. As for the dump go to psp-hacks.com and look for the 2.6 downgrader package as it includes all the files necessary. It doesnt matter if i have already answered these questions. I was once like you...:)

[grit]

But I've eard of others factory 2.60 success, in fact a lot of people stated that it worked great on TA-082..

RockON! ;)

[acn010]

i think those are early models, same as yours, mine is an old model cause mine is the first ones that it came out with the free SPIDER-MAN 2 movie, i was like YAY!!!!!
so yeah,
make sure dont upgrade it cause who knows that the psp will react when downgrading again

[grit]

Yeah. They tryed to sell me the box with LocoRoco.. :p
And told me that by the end of the week new PSPs were to arrive...

Now, one question: Would it be wise to upgrade to 2.00 and then downgrade it again to 1.50 just to be safe? Or is it redundant?

[acn010]

1.50-2.00 it is safe from now. but upgrading to 2.50 or 2.60 is a bit too risky for you

[D0N]

I think it is wise if you upgrade to 2.00 and then downgrade it back to 1.50

[SINIStER]

I think it is wise if you upgrade to 2.00 and then downgrade it back to 1.50
Why do this?
Im just curious.

[D0N]

Because downgrading from 2.60 may make 1.50 buggy and downgrading from 2.00 is perfect and has no bugs and many people have downgraded from 2.00

[acemang]

Hi guys

I just got my psp with 2.01. how do i downgrade.
will this work, without upgrading

[bullhead]

I did the 2.0 upgrade then used the MPH downgrader, just to be sure. No problems as of yet, so im chuffed to say the least...

[zx-81]

It works perfectly with a factory 2.5FW (europe) :).

[grit]

I think it is wise if you upgrade to 2.00 and then downgrade it back to 1.50

Yes, that's what I thought, thanx.

And I've just done that, but I got a little scared because the downgrader (I mean the version changer) didn't create the index.dat.bak file as it should.. Still, I as able to upgrade to 1.5, but..
What do you think?

In the end it seems that everything went OK..

[r00t]

Yes upgrade from version 2.5 to version 2.6 then use the downgrader. Yep the code is alright.

What I wanna say is if I as able to upgrade to 1.50 the version changer worked regardless of the index.dat.bak file creation, right?
This file doesn't have nothing to do with the downgrader itself, right?

All seems fine, I just want to be sure..

TIA for an answer. :)

[amoeller]

This downgrader worked perfect without any problems!
My PSP originally came with v1.0! So i guess that's why it worked so good. Just the problem is some of my new games are 2.6 games and Splinter Cell doesnt work with the UMD emulator so i went back to 2.6 for now until they fully crack 2.6 firmware so it will work. Is there any problems with upgrading and downgrading multiple times that can mess my PSP up?

Thanks.

[mike22303]

please help......if someone can send me the needed 1.5 dump it would be greatly appreciated....im going nuts trying to find it with no luck.... e-mail [email protected]

[ph14258]

just confirming to some readers that the downgrader has worked ok for me.
i purchased my psp 2.6 version second user off ebay, i had no idea of it's history, whether it had been upgraded or was original 2.6 version.
there was no printing at all on the psp's board where told to look before attempting downgrade so i took a chance. it worked fine for me.
whole process from start to finish took around 4 minutes.
i used the downgrader 2.50/2.60enfull.exe file with the talk through guide on pc.

[leon poole]

Mine keeps saying wrong password when i try to unzip it

[nahpxela]

Another success here downgrading it to 1.5 with a NON TA-082.

Updated FACTORY 2.5 -> 2.6, then from 2.6 -> 1.5. Checked system firmware and its now 1.5:D

Good luck!

[Samball91]

my letters are in the top right of the mobo but i cannot read them, should i automatically assume that it is a TA-082 and screw it or should i take my PSP apart and look/ try and decipher the numbers?

[DaVo^^]

What does this "1.5 DUMP" mean?

[steven1980cad]

Hi All,

Downgrading yes it works.

I recently downgraded my factory 2.5 to 1.5 using Downgrader2.50-2.60ENFULL.exe from psp-hacks.
The 1.5 dump is already there, and i didnt upgrade to 2.6 before downgrading.

This does the file transfers for you so i reconmend it.

I also used devhook042a.rar to play my GTA UMD that req`d fw2.5.

At the moment everything is working perfect,

Overall its fantastic,
Thank you to all the coders. I know thats a lot of coders who`s ideas came together to make this work.

[grum1982]

Alright folks.
Had a Jap white (factory) 2.5 PSP. upgraded to 2.6 then downgrade using Downdater final to 1.5. Everything working perfect. Class!

When you bought your psp did the 2.5 firmware come preinstalled or did you upgrade it from a previous version?

[Viralmind]

worked the first time i tried it.
nice, and pretty easy to do.

only thing is, every time i reboot, it says "to start, you must update the system software."

i can just bypass that by clicking ok, but it is kind of annoying.

[lnknman11]

i feel really dumb asking this, but do you need grand theft auto:liberty city stories to use the downgrader, or can you use any game?

[horacehogarth]

Can anyone point me to where i can get the update to Firmware 2.6 file?

So i can upgrade to 2.6 before downgrading to 1.5 i mean.

go to www.psp-hacks.com and "search for 2.5/2.6 downgrader final" download either the 2.5 or 2.6(whatever one u have) rar file this will have everything u need the just drag and drop the folders to where it tells u in the README, ur psp needs to be at 100% battery life and the ac adapter plugged in aswell

[helperdude]

When he said that the downdater cannot be used when those numbers are in the top right hand corner. I have nothing there. But when I open it.... on the top of the inside silver thing, I see half of numbers, what then?

Hi there, I registered just to post this: reporting 100% success in downgrading UK (PSP-1003) black PSP with factory 2.50 FW. I first upgraded to 2.60 (which is CRUCIAL and not documented enough) then used Easy Downgrader FULL version. Once downgraded, I used the auto installer for DevHook 0.46 and all the ISOs I have are working perfectly without playing around with settings etc..., even recent games such as Loco Roco.

Little things I gathered from different forums:
-You need to upgrade your PSP at least ONCE before using the downgrader. If you have a factory 2.60, I recommend you DO NOT downgrade as the risk of bricking it are too high.
-When updating to 2.60 FW, don't worry about where the FW install files are from (USA, JPN, EUR are all identical)
-Same thing for ISOs.
-Make sure you are sober when downgrading.

Thanks to all involved in making the downgrader, as well as all the good samaritans helping out on the user forums.

I first upgraded to 2.60 (which is CRUCIAL and not documented enough) then used Easy Downgrader FULL version. Once downgraded, I used the auto installer for DevHook 0.46 and all the ISOs I have are working perfectly without playing around with settings etc..., even recent games such as Loco Roco.

Little things I gathered from different forums:
-You need to upgrade your PSP at least ONCE before using the downgrader. If you have a factory 2.60, I recommend you DO NOT downgrade as the risk of bricking it are too high.
-When updating to 2.60 FW, don't worry about where the FW install files are from (USA, JPN, EUR are all identical)
-Same thing for ISOs.
-Make sure you are sober when downgrading.

Thanks to all involved in making the downgrader, as well as all the good samaritans helping out on the user forums.

2.5 is downgradable, no need to update to 2.6. Also, a factory 2.6 is most likely a TA-82 motherboard, of course the risk of it bricking is high. Just a little info for ya.:)

Fair enough, however I have heard of a few brick reports involving factory 2.50FW. To make sure I would still recommend upgrading to 2.60 first.

Cheers!

make sure you dont have a TA-082 motherboard just in case. to do that, open your umd drive and look at the top right corner where theres a little green. if you see writing there, you have a TA-082, if you dont see writing there, then its ok to downgrade

hi i need a bit of help were can i get the 1.50 dump from?

[gtgpeople]

has anyone tried this downgrader with a 2.6 psp. my psp was repaired 2 times and is not a ta-082 psp. when i first got my psp it was v1.5 then i had to get it repaired do you think sony fix my psp or just replaced it with a new one. it is still safe to downgrade it? someone plz help!

[Subliminal]

Is that ZIP file on the first post all I need to downgrade? I don't know anyone that has a 1.5 psp.

[Kramer]

yeah that and a 1.5 dump just search on google and you should find a dump

[Subliminal]

I'm scared to search google for dumps because what if they are fake or have viruses? What is the approximate size of the 1.5 dump?

[Kramer]

alright go here www.psp-hacks.com (http://www.psp-hacks.com) they have the full downgrade pack in the download section ive used the one from there twice so dont worry about bricking.
have you made sure you dont have TA-082

[Subliminal]

Thanks so much mate.

[Kramer]

thats cool dude

[jluxe]

hey guys, could someone pm me or email me about the 1.5 dump?
thanks

i downgraded mine without any problems at all.
yesterday i downgraded my friends psp. and we tried to have a WLAN multiplayer game of QUAKE on our PSPs. but for some reason his game crashes when he tries to activate the WLAN and it fails the connecton test, the green light wont even come on. the thing is we dont know if this problem has occured in the downgrading process or not. we played GTA multiplayer a few times before we downgraded. So i dont know what is wrong. Has anyone else had a similar problem? it seems the PSP recognises that the WLAN switch is on, it attempts to connect, just nothing happens. :confused:

[Kramer]

try upgrading to 2.0 then downgrading that might fix the problem

[Physicist]

we did that. but then couldnt find a downgrader for 2.0 to 1.5, well i found one eventually. it was a bit more complicated than the easy downgrader. and it actually said that the downgrade failed, but it still works as 1.5.
his WLAN still wont come on. :confused:

[Method Man]

to downdate i need this:
DOWNDATER\DUMP\ (containing the 1.50 dump)
DOWNDATER\PRX\ (containing the 1.50 UPDATE .PRX files)
DOWNDATER\inputfl.bin
DOWNDATER\outputfl.bin
right? where i can get it from?
can u send it to my email adress:
[email protected]

sorry 4 possible misstakes, but I am a german one

[my3awds]

Hi, I just wanted to make sure this is a plausable way to downgrade. A friend bought a used PSP with no numbers on the motherboard (no IC) and it had a version 2.00. So I wanted to upgrade his psp to version 2.6 or 2.5, then use this downgrade to get 1.5. Should work, right?

[Video_freak]

yes. it should.

[my3awds]

Thank you for confirming. Worked like a charm.

can somebody answer my question?

[rip_la]

Please someone tell me where the root form my memory stick is. I don't know what a root is.

[binary]

IF THIS IS ALL OK, YOU SHOULD BE SET:
* The two files and two folders mentioned above
* PSP\GAME\DOWNDATERTEST\EB OOT.PBP
* eLoader
* GTA
* A PSP THAT DID NOT COME WITH 2.60 PRE-INSTALLED



I see that the instructions say this downgrade CANNOT be run on a PSP that came with 2.60 pre-installed.

Is there any way to downgrade a PSP that had 2.60 pre-installed?

[dejkirkby]

Please someone tell me where the root form my memory stick is. I don't know what a root is.
When you first link up your psp to your pc and you click on the removable disk icon the root is what comes up (it contains all the files on your psp on the first level.

Ok, I'll answer my own question.

I did some research on other forums and it seems that a downgrade of a factory 2.60 will be successful as long as that factory 2.60 does NOT come with a TA-082 motherboard.

Apparently most factory 2.60 PSPs come with a TA-082 motherboard but SOME DONT.

If the factory 2.60 DOES NOT come with a TA-082 motherboard then apparently it will work fine. Other forums are posting successful downgrades using factory 2.60 PSPs that dont have a TA-082.

I do believe that the instructions tell you where to look. (inside the UMD "door") or something along those lines. I didn't use this particular downgrader.

[Mohsins16]

:(
"I would like to know how much space the FINAL version of the downgrader takes up and how much free space is left on the memory stick as I only have a 32mb

I already have the neccessary dumps and files & shit, I just need that question answered before I can go on."

Help, please?

Are you sure your version of GTA isn't patched?

[-Outlaw-]

My psp is version 2.50 but it does not have a code just inside the umd door. Is it safe to downgrade?

[uudem]

[uudem]

[JD/]

yup but if I was you I would upgrade to 2.0 and downgrade back to 1.5 because there are some bugs when you go straight from 2.6 to 1.5

Currently, its not possible as the GTA UMD is required for the exploit to work.

A new exploit is being worked on so there's still hope!

[Jimiboni]

damn! dont know where can i get the game..they are all sold. tnx anyway for the information

[S-B]

Just finished downgrading, worked a charm. Highly recommended to well, everyone with a 2.50 or 2.60 PSP.

[CoachMonkey]

so if i have a ta-802 motherboard, i won't be able to downgrade it at all

basially i gotta go get a psp without one?

and another question

i got the dump folder, but when i put it in my mem stick and accessed it in the psp, it would say corrupt file, any idea why?

[razorak]

u got a copy of an unpatched gta monkey? u'll need to use the GTA eloader unless u wanna upgrade to 2.71 and use the downgrader that doesn't need the gta eloader

and btw there is no downgrader released for ta-082s yet =(

[CoachMonkey]

no i don't have a unpatched gta :-/, and i tried to upgrade it this morning to 2.71 but when i put in the file to upgrade it, my psp would say corrupt data, so i couldn't upgrade

so what should I do?

return this current psp, and hope to get one that isn't ta-082? and then rent an unpathed gta and just downgrade?

[madvirus]

Great effort to mention the steps to downgrade PSP... but I a mlooking for the rar password of the file...

[rwithtfallen]

what was the password again?
i could'nt get it to work...

[Sk8.4.Life]

Does the downgrader still work with the new TIFF version of eLoader? I'm just curious because I'm going over to a friends house tomarrow to help him downgrade his 2.6.

[Video_freak]

This downgrader works with GTA...

[Sk8.4.Life]

I just scrolled through the last few pages and I found someone saying GTA is required to run the downgrader, so I'll just take my copy over there I guess...

[Video_freak]

Make sure it only asks for the 2.0 update. ;)
