So, just bought an PSP with a broken screen, changed the screen to a working one, OFW-> 3.71 M33-2(w/pandora), tried to update to 5.00 m33-6 the normal way, works for a while, bricked, unbricked w/pandora, couldn't update to 5.00 m33-6 the normal way(went beyond the 84% all the way to 99%, then dropped back to 84% and kept doing that over and over), bricked again because of that, unbricked, flashed using hellcat's recovery flasher 1.50 to 5.00 m33-4, and now:
Keeps freezing while just browsing around in the XMB, while pressing 2 buttons simultaneously in a game(randomly), right when it boots into xmb(while the sony text is still there), when starting a game, when moving around in recovery menu, etc etc...
I've tryed 'Format flash1 and reset settings', helped me just once for about 15 mins of gameplay, then started doing it again.
Help people, this is just f*cked up >,<.
E: Tried to install 5.02 GEN-A, the same thing with it, bricked again... >,<
