hey i had 3.52 m33-4 software and i attempted to downgrade it to 1.50 using this tutorial http://youtube.com/watch?v=GZfVWwYGnmA

i followed it exactly and it seemed like it was working until it came time for it to restart after it was installed. when i hit the power on the screen only stays black and nothing else happens.

can anyone tell me whats wrong and if its possible to fix

did you got the Blue Screen of dead?, the one that tells you to pres O.

try removing the battery for about 5 minutes, and then try to turn it on

you may have a brick though, why in hell did you wanted to go to 1.50 in the first place?

Yep its a brick, your only way out now is pandora. as for 1.50 being needed to customize, customize what exactly.

Do you know anyone with a psp running custom firmware to make you a despertar cementario memstick this will upgrade you to 3.80m33-5 from a brick, if not you will need to buy a tool battery made by datel and download an easy installer for pandora, but you need a memcard reader for the pc for this to work.
