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.

Download Link: [eLoader 0.995 "Kriek" Windows Installer] (for xLoader)
Download Link: [eLoader 0.995 "Kriek" ZIP Files]
Mailto: [0okm00@gmail.com]

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."

Maybe this will stop people from talking trash about him, when in reality he is a great dev? If you have to ask him for the downdater he took time and effort to create, you will not only notice he is a PERSON just like everyone else, ans also appreciate what he has done for you and your PSP.

he doesnt make it public because he is going to hold the carrot in front of your nose and make yo beg while he cashes in, which is his right, as long as he is the one that holds the gold, he rules. I would wait wait until the DAX Team throws a downgrader together before I got excited.

Some people are born to be raving retards. With the sheer amount of recent developments happening lately, one could certainly hope for a more updated downgrader. But I'll hope for a more stable, idiot-proof downgrader first. I'd hate to brick my unit because I spaced for a second.

0okm is wierd - he always does things very strangely. I don't get it either. And why didn't he make it downgrade to 1.5?

   Re: Enlightened...? (Unregistered) - 2007-01-02
 » I never know what to put as a subject
Because a 2.80->1.5 downgrader has already been made, but a ta-082 can't downgrade to 1.5 normally.
If you mean a 2.80->1.5 downgrader specific to ta-082 using dark_alex's newly released source code, its probably cuz that would take alot of work, with relatively little tangible benefit.
And either way, 0okm seems to be more the type to get it done quick and dirty, rather than slow and refined.

You're not any closer to being able to downgrade just because 2.80 can. 2.81 doesn't have any usermode exploit yet, but once (if) one if found, we have automatic kernal access (which means downgrader) because of an exploit recently found, we just need some usermode access to launch a dger

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.


   Re: FreePlay (Unregistered) - 2007-01-02
 » Collaboration? Uh, no.
They actually dislike each other quite a lot. In fact, when D_A and Mathieulh released their TA-082 downgrader, 0okm went so far as to say it didn't really exist.

This is about as much collaboration as there would be between me and Microsoft for the fact that I use their OS.

   Re: Snarg (Unregistered) - 2007-01-02
 » .
He still hasn't proven anything.
He just took D_A's downgraders, and combined it with the other 2.8 downgrader. That doesn't prove that he was ever able to do anything on a ta-082

   Re: FreePlay (Unregistered) - 2007-01-02
 » LOL
"Proven?" My ass. 0okm said that a TA-082 that was downgraded through software would NOT be able to use a regular update EBOOT. He also said that downgrading would require that he get a RAM dump from the TA-082 and create a special, unique firmware dump BY HAND.

None of this ever turned out to be true. There's a universal TA-082 downgrader for 2.71 that doesn't require any of that garbage, and you most certainly CAN upgrade after downgrading.

This was posted by him before new year's eve, and it was about the previous downgrader by dark_thug. This one was ACTUALLY fake

"posted by 0okm @ 12/31/2006 11:58:00 PM"

That's not before New Year's Eve.

Dark_AleX's downgrader came out on the 27th. Dark_thug's fake came out on the 17th, and had already been disproven long before Dark_AleX's was released. It makes no sense to think 0okm was referring to Dark_thug's fake.

You don't need balls to try to find a 2.81/2 exploit, if you just ***** around, the worst that can happen is your PSP crashes, as long as you don't modify your flash memory. If you screw around on devhook emulating 2.81/2, there's probably 0% chance of bricking
