Yes did that and it just froze then had lines then froze on the game screen again and turned of again. What a pain in the backside. i will see if i can get my money back through ebay or sell it as faulty.
The last thing to try while waiting on the ebay issue and selling would be to reflash the entire thing by following the guiodes I sent you. It's really pretty easy to do and doesn't take much time.
I will give it a go. I will just buy one from a shop next time and not bother upgrading. The other psp i have doesn't charge after being upgraded i have to take battery out and charge it externally.
This is on the PSP that you already owned? Cool. Notsure why that battery doesn't charge though. You up to date on M33 custom firmware is what it means. They are not releaseing any more until v4.0.
I will try swapping memory cards and batteries around and see if that makes things different. Ideally i would love two working psp's. Fingers crossed. I will try all the things you have suggested.
