Well, I wanted back in to the whole PSP 'brew scene (I remember the good old days of the Swaploit... :Punk: left around the time of 3.71-M33). So, I bought a used PSP-2000 from my friend.
It's a God of War edition -- TA-088v2. In other words, it can be hacked, but can't make Pandora's Batteries. I used my falling-apart PSP-1000 with an almost entirely shattered screen to turn my phat battery into a Pandora, and hacked the Slim. Got it to work just fine. The problem now is that somewhere down the line, I think I accidently Pandora-ized the slim battery. Now I can't boot the Slim with that battery, and when I put it in, the Slim turns on the green light without me touching any buttons. I can use it, but only after I boot with my phat battery or the AC adapter.
So now my problem is, how do I fix the problem with the slim battery? I can't do anything from my Slim, as it's past TA-085v1, so I can't make Pandora's batteries or reverse the process on it. I tried with the Phat (you can force a Slim battery into a Phat) but most of the screen I can't read, and it doesn't seem to have worked.
