Ok I have a problem.

I had firmware 6.00 and tried to downgrade to 3.71m33 unaware that it was imposible. Now My psp starts but my XMB wont load and it cuts off. Is there anyway i can fix this?

what psp do you have?

i think he has a 2000(maybe TA-88v3) or a 1000.

I have a 1000 but I found something and fixed it. Thank you

It's not impossible anyways. Might have just been a semi brick or something.
