Sembra incredibile, ma è stato rilasciato un downgrader-funzionante-per le PSP aventi la scheda madre TA-082.

Ragionevolmente ancora una volta si raccomanda massima cautula anche se sembra che funzioni a dovere.

Ecco le prime impressioni, feauture ed istruzioni per l'uso.

Citazione:

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. 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 again. It will most likely brick your PSP!

Instructions

1. Use the DAX generic downgrader to change your ver. to 2.50 if it isnt already.
2. Downloaded the 2.50 TA-082 Check & Dump v1.20 to dump your firmware.
3. Enter your settings in the executable.
4. It will generate the downgrader. Copy the folder ‘UPDATE’ (the folder it makes) to x:/PSP/GAME
5. download eLoader and put it on your PSP. Load it from the photo menu.
6. Choose ‘UPDATE’ from the eLoader menu. This wil begin the downgrader. It will patch your bootstrap to make it a 1.5.
7.Reboot your PSP AFTER it has finished COMPLETELY! You should get a blue screen. Hit O and restore your settings

EDIT Sembra ci siano dei problemi, questi:

Citazione:

- 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
