I had bricked my psp and used pandoras to unbrick it. But now im stuck on 3.52m33-4 any firmware i try to dpgrade to it gives me the cta800025 error. So i guess i cant fix this problem because i dont have a backup of the keys. Will all my isos still play with 3.52m33-4 or will i have to get a loader or something?

CTA80000025 = region key (0x100) is damaged or missing (irrecoverable unless you have a backup)

http://forums.maxconsole.net/showthread.php?t=96911

you should have made a backup of your keys or nand, bacause somehow you have screwed up key 0x100, and you cannot fix this broken key...
this usually happens if you flash someone elses nand to your psp (hence overwriting your own keys...not good)

I AM NOT RESPONSIBLE IF YOU TRY THIS BELOW:

very risky step (DO NOT TRY): you could try flashing someone elses key 0x100 from the same model psp but this is NOT RECOMMENDED since keys are unique to each psp. some people seem to have had partial success (I cannot confirm their reports)with this but often things like UMD drives stop working due to incompatibility

very risky step (DO NOT TRY): one or two people seem to have had limited success flashing key 0x120 to 0x100 (if 0x120 is different to 0x100)but again I do NOT RECOMMEND THIS and cannot confirm their reports
