I seriously dunno what to do guys.. had a bricked psp, installed 5.0 OFW on it countless times using a pandora. Then whenever I try to update to a 6.xx OFW it doesn't reach 100%, gets to 99 then back to 85 again.. Then I have no choice but to turn off the psp during the install.. Then When I reboot it seems as if the OFW was installed properly, but then I try to load the pro updates and the psp just goes black then off. I've done this with 6.39 pro b7 and 6.2 pro b7. This psp 1k doesn't seem to like any 6.xx FW/CFW at all.. Everything was working fine on 5.5 prome-4. Then I tried to update, and got screwed over.. Also I've formatted several times.. Help pleeease, I need to install Pro b7 for a friend.. this never happened to my psp..
