I see..One of the first C releases, but B did as well, and so did the 5.x firmwares, etc. The current B and C ones are fine.
If you can downgrade it to 6.20, it can perm (still no brick recovery/pandora, that stopped working halfway through the 2000 series).
Can you give me a refresher then. What do I have to do to brick the PSP. I assume that with 3000s, once they're bricked they're bricked for good unless I'm Sony. I never messed with flash 0 or anything before. Only emulators, psx and backups.
