Okay, so... My PSP is a 2000 slim, and it was working great. I just updated it to gen-D3 and Prometheus, and it was fine. Started playing Kingdom Hearts...and it was fine. Then all of a sudden, it went black and shut off. Tried turning it back on, but it had bricked symptoms (green light was on, but nothing else, then it shut off again). I took the battery out and left it for a bit, put it back in, and it was okay again! So I went back to Kingdom Hearts and after a bit (not the same place)... it bricked again. Took the battery out again, and this time it wasn't okay. Went into the recovery screen, and while I was trying to find out what to do...it shut down again. EDIT: Okay. So...I finally got it into recovery again and ran the fix, so it's back up again. How do I prevent this from happening again then? It was just killing itself while playing Kingdom Hearts. Is the ISO bad maybe?
