sup guys, wel i have a 1.00 psp and i tried the ir shell on it and it worked perfectly. then i used themepsp through the ir shell and installed a superman theme, and it glithced my psp a lil, so i just updated to 1.50 and then downgraded to 1.00 again nd i saw that everything got fixed, so then i thought that maby it wus just that theme that wuz fucked up, so i tried the pimp my ride theme, but then wen i exited the ir shell the psp restarted normally and then wen it wuz about to load the menus, it froze and just shut down. and now wen i turn my psp on it loads up and u see the bg but then again wen its gunna load the menus i freezes for a ouple of seonds and den shuts down. if i place a umd that works on firmware 1.00 like the demo disc that the psp brought, it starts up perfectly but wen i press home and yes it does the same thing as i stated above, only this time it also shows the battery meter. another person from another forum told me that its prob a font problem inside the psp flash. is there any way that i can fix this. all i need is a way to run the fileassistant so i can replace the theme files with the default files. any ideas any1?

seeing as you have no way of getting to xmb all i can think of is getting a modchip to repair the stuff you flashed?

That must suk your PSP is immobilized.
Your situation is unfortunate, because you require a mod chip.(U.P.)
