Firmware 2.80 to 2.71 downgrader for TA-079 - TA-086 PSPs *UPDATE*

PSP


Adding to the huge list of hacks and exploits in the last few weeks is another piece of work by 0okm, this time a firmware 2.80 to 2.71 Downgrader for TA-079 - TA-086 PSPs. What this means is that 2.80 people who're stuck with a TA-082 or TA-086 PSP can now downgrade to 2.71, and from there, downgrade to 1.5 using Dark_AleX's TA-082 downgrader. Once on 1.5, it has been proven that everyone - including TA-082ers - can upgrade to 3.02 OE-B and have all the fun that the rest of the PSP public is having.

But just like the last downgrader by 0okm, don't expect it to be as easy as a downgrader by Dark_AleX. He seems to be not releasing the downgrader in public: You have to mail him and ask for it. While it would take me two minutes to mail him and obtain the downgrader and post it here, I will respect his decision of not releasing this in public.

To ready yourself for the downgrade, here's a list of things you need:
  • The latest PSARDumper.
  • Firmware 2.71 Update Eboot.
  • PBP Unpacker.
  • The actual downdater. (Available on request)
Download links to all of these are at the bottom of the article. Once you have all these things ready, you'll need to find a friend who has a PSP (with firmware 1.5/2.71 HEN-D/2.71 SE/3.02 OE), which can run PSARDumper and extract the DATA.PSAR file.

Here are the steps you need to take:
  1. Open Firmware 2.71 Eboot in PBP Unpacker.
  2. Extract the DATA.PSAR file somewhere on your PC and move it to the root of your Memory Stick. (On helper PSP with 1.5/2.71/2.71SE/3.02OE firmware)
  3. Extract and run the latest PSARDumper on the helper PSP.
  4. Press Circle when in PSARDumper to dump encrypted without sigcheck and dump reboot.bin.
  5. Once the DATA.PSAR file has been dumped, move the newly created folder to the PSP which you want to downgrade.
  6. Obtain the Downdater from 0okm and use the noobz team's xLoader to run the Downdater.

UPDATE: 0okm is finally releasing the "golden" downgrader file (as regarded by not a few) to the public. According to him, his inbox was flooded by requests for the file. So to avoid having sore fingers replying to every single request, he just made it available for everyone. Still, as 0okm himself warned, just get it if "if you know HowTo use and can take the Risk."

Why are'nt they realesing it for public? I think there will be to much requests. Is there a special reason why they don't do it?

 » shut up
0okm contributes loads..
i assume he is making people email him for it as lots of people bricked because THEY did it wrong last time.
in a way emailing him is proving that you accept responsibility.

Yes, only 2.81, 2.82, 3.0 and then my 3.01 to exploit now. It looks like a collaboration has been made between D_A and ookom as ookom is using D_A's Downgrader to help downgrade to 1.5. Good job, but plz release it in public, let those dumbasses brick their psp's it's their own fault.

I would give the file to whoever needs it but i already got banned by qj forums for distributing the 1.50 files for the 2.80 Downgrader (NOT THE THE TA-082~TA-086 ONE THE ONE FOR NON TA-082 PSPS)

But if u want it go to:

http://treo-gaming.awardspace.com and look at the bottom of the page for the email link. Then email me and I might send them. (Depending on the space on my memory stick)
