Ok. So i bought bricked PSP. It's a mint condition Phat. I pandorized it and it works, but it has bunch of problems.... When you turn it on, UMD drive keeps reading (quite laud) and stops after 10 sec. None of the programs works. You see PSP logo white screen and system freezes. Even in recovery menu (on+R) you can't exit it couse it's freezes. I used 3.80 m33, with same settings from recovery menu as usually. I never seen anything like that before. I don't have expirance with fixing nand, but can someone help me with it?
