TA-082 Downgrader Released
Posted on December 16th, 2006 in Site News by Chaos Zero from psp-haxors.com

Created by dark_thug(pinoy programmer in bahrain), this downgrader is for 2.50 TA-082 PSPs.

Other than the generic 2.50 TA-082 Downgrader name, I’m nick naming it the TA-082 “Kick-ass” Downgrader!
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!
