I recently acquired a psp from a friend who had believed he had killed it completely as it was bricked, i told him i could fix it once i did i tried to give it to him and he just told me to keep it because he had been given his other friends psp because he no longer played it.
So i got a free psp well shortly after fixing it i had noticed that if i went into the settings it would blue screen of death every time, re flashed same problem, i guessed that maybe his flash1 was corrupted or damaged. So i just used it for umd games and such while my normal psp sat in its case in my unless i wanted to play an emulator. Then once i went to use it in the last week it was bricked again and its flash refuses to fully reformat using the pandora battery. it just freezes at around 75 percent where it tries to make the directories, so the firmware wont flash. What can i do to fix this and what causes this, Im guessing that his flash0 got corrupted or damaged im guessing????
