hi i have 3.52 M33 and i tired to put the original 3.50 OFW files UMD9660, UMDMAN, and THREADMAN into my psp flash0/kn because my UMD drive wasnt working...so i exit recovery moded and everything is fine. i turned off my psp but now when i turn it on nothing happens. the screen doesn't even brighten. i dont think its a brick cuz after i put the files in it worked fine but when i turn it on, it stays on for about ten seconds then it turns off. cant get into recovery mode either PLZZ help!
