Or create a UPMS stick & pandora and that has the option to boot to full firmware via the joker menu. Hit the link in my sig if you do.

Both methods described here will work.

PsP#1 : 2.01>3.71M33-4>3.80 M33-5
PsP#2 (Slim) : 3.80>3.90M33-2 All hail the UPMS Stck
If you need a UPMS Stick go here and then go here :-) *As recommended by January39
