Hi all. i have a huge dilemma. my friend had given me his psp so i could downgrade it from 2.80 to 1.5 then back to 3.10 oe-a. the problem is when trying do downgrade from 2.80 to 1.5 something went wrong and now all that comes on when i hit the power button is the green light for about 5 seconds then it shuts off entirely. did i brick my friends psp? if so how could i replace it for a resonable cost? Help would be appreciated.
