i have a fat psp. What happened is after creating a magic stick and battery to downgrade a friends psp, i reverted my battery and formated the ms and i got a red screen(dont remember the error code) so i borrowed another psp and was able to re-create the pandora battery and majic stick and re-flashed the latest dax firmware and gave back the psp and the next day i reverted the battery and ms and had the same issue.
When i turn it on i get a green light for about 15-30 sec then it shuts off and no screen. When i hold the R button i get ms access and the screen comes on but remains blank.
Is there a way to recover without seeing the screen, or do i need a pandora battery?
And i am sure i will have the same problem once i can get my hands on a pandora battery
