This is my first post! I bought a PSP for a long flight to the uk from canada and I had upgraded to 3.50 FW to play Socom (requires 3.50fw), as I am an avid downloader of torrents I found you could download PSP games and I started to read about it. I was dissappointed that 3.5 could not be downgraded, then 2 hours later a release from noobz - i quickly searched the city and bought lumines. I downgraded to 1.5 - Everything OK, did not brick, but I had a screen issue. It would illuminate for 1-2 seconds then go black... If i pluged in the power/usb cable, and removed the power, it would show the main menu etc.... I upgraded to 3.40oea right away, but the problem happened again, I guessed to hit x to continue to patch my mobo, and guessed to hit x again to continue upgrading (fear of bricking, i didnt want to turn off/etc.) So - I get to 3.40oea, I have 8 games on a 4gb card, everything is ok - when i go to oea menu (to set mhz of cpu etc.) the screen went blank!! plugged in power/usb, removed, the scren came back.... Put IRSHELL into game150 - it will start, show for 2 sceconds, and go blacnk... plug in usb/power, remove, it will show.. Every time I go to 1.5 mode (or when i had 1.5 installed), it would go blank unless i use the power.usb trick Sorry for long post, please help! Girlfriend seems to think controlling our 42 lcd tv is cool with psps haha.
