Bricked PSP 2 years ago [full brick, hold power button up and nothing happens / orange light with charger plugged in]
I never thought this thing would work, but it worked flawlessly. Follow the instructions.
The memory card is not official sony but it works just as good.
You have options of which firmware to install. When all is done you can then format your card in the psp options and use it for games/saves, or just keep it as a backup in case you brick it again.
Ordered thursday 5pm, received Monday (!) on economy free delivery
