Ok, long story short it was mine but I gave it to a friend of mine roughly 5 - 6 years ago & he has absolutely no knowledge of hacking/modding where as I have moved on to Android since then so I'm a little rusty now, my question is: Can I update an old PSP2001 (dated July of 2001; looking under the battery.)? It is already modded running 5.50 GEN-D3 but, again, this was years ago when I did that. He has a 2 & a 4 GB SanDisk memory card, the charger & PSP to computer USB cord but he can't find the jig-kick battery I made to mod it & neither of us have nor ever did have a Pandora battery in the first place. Would it still be possible to update the software to another, up-to-date custom firmware or an up-to-date official firmware then re-mod but w/ just the above listed items? He has just the one battery so no, I am not going to cut it open just to turn it into another jig-kick, IF that method or the Pandora one are still the only way to exploit it, I don't know anymore, please help me to refresh my memory.
