It is now possible to downgrade or unbrick any current PSP using Pandora's Battery.
However, a homebrew-enabled PSP is required to set it up.

The following downgraders do not require another PSP.

2.80 Downgrader
2.80 Homebrew Enabler (HEN)

3.03 Downgrader
3.03 HEN

Note that the 3.03 downgrader (and HEN) requires an original, unpatched Grand Theft Auto: Liberty City Stories UMD to run.
However, you will only need the UMD once for the actual downgrade, you will not need it afterwards.

3.50 Downgrader (includes 3.50 HEN)
3.50 Exploit: "Illuminati" exploit found by Noobz.eu and Archaemic

3.11 HEN and Downgrader (corruption free)

Note that the 3.50 and 3.11 downgraders (and HEN) requires a real, original Lumines UMD to run.
However, you will only need the UMD once for the actual downgrade, you will not need it afterwards.

If you downgrade to 1.50, you will be able to install 3.40 OE-A (or any other custom firmware).
Here's a (non-comprehensive) feature list for 3.40 OE-A:
- play real UMD games (which require up to 3.40 firmware)
- play real UMD videos (and region-free)
- play ISOs (backed up UMD games) from the Game section of the XMB (and NO-UMD)
- run homebrew that uses the 3.40 kernel (put it in "ms:\PSP\GAME\", where "ms:" is your PSP memory card drive letter)
- run homebrew that uses the 1.50 kernel (put it in "ms:\PSP\GAME150\"); almost all homebrew goes here
- watch MP4 videos (put it in "ms:\VIDEO\" and it will come up in the Video section of the XMB)
- browse the web using the Internet Browser
- play PS1 games using the official Sony emulator
- prevents accidental firmware updates
- recovery mode (hold the "R" shoulder button when booting)
- plug-ins for extra functionality

Nice to see you found my info useful g4m30v3r.

If a Mod reads this, please make it a sticky/pinned topic on as many of the sub-forums as possible.
I cannot count the number of times I have said on here that 2.80/2.81 is undowngradable and cannot run DevHook.

I think it's because they get their psp, upgrade it to the highest firmware available, THEN find out about homebrew!

Silly n00bs...

yeeah = ] i quoted you.. it says from adw888 = ]

hey...i understand there is nothing out yet
but the only thing i would like answered is,
is there any hope like will someone be able
to crack this version you guys reckon?

There is always hope; even if there's nothing in development at the moment, someone might just stumble over something.

yes true say...http://www.pspx.ru/forum/showthread.php?t=18678

that forrum is a bit nutty but i think theres a couple people working
on 2.81

very helpful for the ppl who are getting scammed by fake downgraders

anyone know whats going on in this video?>>> http://www.youtube.com/watch?v=tsb9bWAeI4k
dunno if its just bullshit or perhaps a solution help please

I doubt we'll see either of these things come out till the 2.8 eloader's released at the very least

NEVER trust anything on YouTube, EVER.
I watched the video and all he has done is use DevHook to boot 2.71 or below and change the text to say 2.81.

If there was any slightest chance of a solution, it would be all over the front pages of the PSP sites.

ok man thanks for your help guys

good advice to noobs

is there no way to downgrade a 2.8 psp?

there is currently NO way to downgrade a 2.8 psp

i think this is a good sticky and that people will benefit from it

rofl.. my retarded friend decided he wanted to update me from 2.71 to 3.03. What an arsehole....

Updated by me

thanks harry!

sorry man i was on vacation! missed all these good news!! ahhaha

= D

Well ive got nothing to contribute. However, ive never noticed this before. I'd just like to say good work to the three of you. No doubt we will still get many questions on this topic though.

Too bad Im currently using 2.81 and upgraded to 3.03.

Should have bought 1.5 which my friend's using it and all goes well.

Ok, my bother has a TA-082 with 2.81, what can be done. I am willing to wait, it says u can run Devhook, can u downgrade it????

It also says its not out...

So if I wait he can run Devhook? Wat about downgrade, or duz that take longer??

dude u retarded? it doesnt say that.. your brother cant do shit wit ta-082 2.81

Hey dont flame!



Anyways, is thsi for 2.81 NON TA-082???

Nice post. I have a friend who just got a 2.81, so I will keep an eye on this one.

thanks

So this thread is the thread to look for the annocuement?

As well as the front page and news, yes.

ill keep looking...

I've updated the first post with links to the 3.03 downgrader and 3.10 OE-A.
In fact, I practically rewrote the post as, with all the edits, it was getting a bit messy.

Any idea when the 3.10 downgrader will be out? Thanks for all the info =), now i dont have to search all over the forums for the info =).

There's really no way of telling when a 3.10 downgrader will be out.
It is dependant on when (and if) and exploit is found for 3.10, allowing the running of unsigned code.
This could be tomorrow, next week, or next year; it is almost impossible to tell.

Man, I have 3.11 firmware... ugh... All my friends have the Version 3.03 OE-C and I feel dumb... ugh... But this time I am going to wait it out till the next exploit... yep yep

Alternatively, you could try selling your PSP and buying one with a lower firmware version.
There's really no telling how long until (or if) an exploit for 3.11 will be found.

very intresting really...i wanna see a 3.1 downgrader so i can use it for my buddy that has 3.1 haha..he says he wants to do homebrew now amazing huh?

what about 2.81
sorry im just a confused newb

Yes, it is possible to downgrade 2.81. However, you need a real, unpatched GTA:LCS UMD.
If you have one, then you can upgrade to 3.03, then downgrade to 1.50.

You should add 3.30 OE in there! Or maybe close this it's kinda old!

[Updated 20070624 with 3.50 Exploit]

3.50 was decrpyted, but No OE yet, they are working on it. Hopefully a downgrader comes too!

[Updated 20070824 with Pandora's Battery]

i've been reading here, there and i got confused and a question, do i still need liberty city stories or lumines to downgrade a psp with sony firmware, or only with the custom battery and the files in the memory stick???

The custom battery and files on the memory stick will downgrade any firmware version, but you will need someone with a homebrew-enabled PSP to set it up.
Using Pandora's Battery, you do not need any UMDs.

The GTA:LCS and Lumines UMDs are if you don't have access to a homebrew-enabled PSP or can't get hold of Pandora's Battery, and still want to be able to downgrade.

ok now i get it, now it's possible to downgrade without the games and able to revive bricked psp, the two things, only with the custom battery and the files, got it thanks

[Updated 20070910 with 3.11 Downgrader]

Um im running the 3.40 OE or w.e by DARK_ALEX and when i try to run .CSOSit doesnt work
Says "The game could not be started. (8002032)"

can anyone help???

Hi Fir3x, and welcome to Console-Spot.

Which game are you having problems with? (if it's a newer one then it might need above 3.40 OE-A)
Have you tried changing the No-UMD settings in the Recovery Mode? (full power off and hold R when turning on to get to Recovery)
