What I was not aware of is that the pandora technique in not necessary to downgrade from custom firmware psp's. You'll rarely brick the PSP for all eternity, but you'll make it hard for yourself if you don't have a recovery plan.
So in case there are others like me, I thought I would share my knowledge. If you are still feeling brave, read through a couple of times and do a 'dummy run' so you're comfortable with the menu thing but don't actually do the disable in step 3 until you're sure you know exactly what to expect. I don't know, But somewhere in your downgrade process you messed up.
Hey something isnt working here mind helping me out?
This is designed to remove custom firmware easily and restore a classic 1.5 firmware back to your psp. ), maybe they shouldn't have been messing with something they knew little about in the first place but I digress...
Most people know of the famous pandora battery technique which will unbrick and/or downgrade a psp's firmware. All should not be lost if you have the means to reinstall the custom firmware.
