UPDATE- ITS A FAKE - TA-082 downgrader

- eloader cannot load prx's
- The file 271se.thug is just a 2.71 sony updater
- When choosing to downgrade to 2.71 sec... it just writes that file to the output directory
- Where are the 1.50 files then? where are my systemctrl's prx which are the core of SE? where is the recovery of SE?
- The txt file that it generates with supossed keys, doesn't seem to be used at all by anything
- The guy that created this scam: the first result in google, a virus page
- He also said something about having a 2.81 TA-082 with UP which cannot
- The program should just crash eloader, but not brick any psp

Created by dark_thug, this downgrader is for 2.50 TA-082 PSPs.

If you are a TA-082 user with a 2.60 or 2.71 PSP, you can downgrade back to 2.50 using the DAX generic downgrader.

So users of 2.50, 2.60 and 2.71 can all downgrade to 1.50… Or 2.71 SE-C!! You can choose 1.50 or SE-C. dark_thug gives a warning though: SE-C may lock-up while playing some games.
The catch? On 1.50, trying to change settings menu gives a Blue Screen of Death. (Read 4a. on the instructions for a possible fix)
This means you can simply not change your Video options, System settings, etc.

Homebrew, USB, Music, Videos, Pictures, Games; all remain.

On a brighter note, the BSoD could theoretically be fixed, using an app like X-Flash to flash a new system reg from a 1.50 user! Or, while making the dump, switch the 2.50 reg with the 1.50 reg. This is risky however.
The TA-082 Boards can also be downgraded to 2.71 SE-C! The BSoD will be gone. The catch again, you may not be able to return (to 1.50). If you can, it will most likely use the same update made to downgrade from 2.50. That still has not been tested.

Last thing, 0okm mentioned this before. Doesn’t matter if you choose SE-C or 1.50, you CANNOT upgrade to 2.50 or down. It will most likely brick your PSP! But you CAN upgrade to 2.60+!

UPDATE: If you downgrade to SE-C, you can still go to 1.50! Simply use the TA-082 program to make a 1.50 update folder, and use SE-C’s RECOVERY Mode to run the update!

I can not stress this enough: If you do not know what you are doing, don’t attempt this! There is a high chance of bricking your PSP! Use at your own risk! I would love to thank dark_thug for the downgrader, and 0okm for the work he has but into TA-082 PSPs!

And of course, to xPSPx Skull xPSPx from PSP-Hacks for being brave enough to test this!
