Some months ago, I decided to update my PSP 1001 to the newest firmware (That I can't remember the version). When the update was in 99%, I got an error FFFFFFFE and I just can't turn on my PSP 1001 again. When I push the power button, a green light appears and then disappears. I also can't turn on in Recovery Mode (or Secure Mode)... can someone help me ?!?
