ok I download some demos into my psp (i have firmware 3.52 m33 with a custom theme) and when i load them the screen turns black and like 10 seconds later my psp turns off, i can play emulators and other application without a problem I haven tried with a umd because i cant find my games and havent had the chance to rent one, can someon plz help?

Make sure you unzip the demos then put them in your GAME folder, if that doesn't help...

Try downloading the psp demos off of your psp web browser. If it shuts off, try it again and make sure you let it install 100% first and that you have a good signal the whole time.

I had already done that, and it didnt work, there was even that icon in "game" that when u highlit it the background changes to one of the games and then its all black and turns off.

back up everything off of your memory stick then format it and then install your demo first to see if can work now, if that doesn't help then you either might have to try a different site because either the file is corrupted or it didn't download right.

Try filefront.

Try (if you haven't already) turning you psp's game folder to 3.52 kernel, in the recovery menu
