Hey guys / gals. So, I was hacking a friend's PSP today following Rydian's guide (which is Awesome, btw (A thousand thanks, dude)). The PSP was running a hacked v5.00 M-something (I forgot which one to be precise), so I ran HellCat's Recovery flasher. After the Flasher was done, I took out the battery and then put it back in, but the PSP didn't want to boot. I tried it twice, with no luck. So, I took my PSP's battery and put it into the other one, and it worked. I wondered what may be wrong with the first battery, that the PSP didn't boot. I put that battery into my PSP, and got the same result, my PSP didn't boot. I'm speculating that battery has been Pandorized before, as my friend bought it at some weird store and it was used. Can anybody help me?? I need to know if there's some way find out if the battery's been pandorized, and if so, how can I de-pandorize it, if possible. Btw, my PSP's currently hacked with the 6.20 Pro hack on Rydian's guide. Thanks in advance to anyone who can provide any kind of info or help. Cheers.
