Finally! Yup I "upgraded" my PSP-1000 (or phat) to custom firmware 5.0 M33-6.
I always wanted to but was too sceptical, afraid of "bricking" the PSP. So with the newer PSP-Go! coming out this fall (which I am getting), it wouldn't hurt much if I did brick my PSP (not knowing there's an unbricker, ironically). With my PSP updated with the latest official firmware, 5.30, I had to make a Pandora's battery and Magic Memory Stick. The battery is just basically a regular battery but 1 wire snipped. One small wire amoungst other small fragile wires. Get where I'm going? So I tested my surgeon skills and tried to seperate that wire. The battery itself was a killer to open with electrical wire attached to it. After picking, cutting, prying, gnawing, biting at the cover, I forced it open with a screw driver. I isolated the correct wire and starting to saw at it. After I was certain the two ends seperated, I taped it all up and tried to reboot. Anti-climatically, it failed.
So I just lost a good Sony OEM battery. But why now, I was too intrigued to let the PSP go to waste. I bought a Pandora's battery and PSP battery for $40. Set up and installation was tricky at first, because you don't know wtf you are doing. Needless to say, it was well worth it.
TG-16!!
