After searching the net I came upon this website which is the best resource for info on the PSP.
I've been trying to install CFW 5.00-m33 on a phat PSP using a pandora battery and a MMS created with Rain's ultra MMS application. Somehow during my fumbling I've semi-bricked the PSP which isn't too much of a problem as I can still boot the PSP into the recovery menu. The problem is that when I try and install the CFW, the whole thing freezes at 5% as the screen says "flashing files".
I've formatted the Lflash and even tried installing OFW, but nothing works.
Any help would be greatly appreciated.
