Answer #1
pretty sure you bricked your psp… and i don’t think that ‘s reversible.

Answer #4
You are using a pandora battery, right?
Answer #5
Dam, If its bricked and you can’t unbrick it with the pandora battery it will become a really nice paper weight.
Answer #6
back in my day ( ) there used to be a recovery console. I think if you held LB and start or something during boot you got a few more options. Not sure if it’s still there.
