For people who keeps bricking their PSP when installing this firmware, or hanging/freezing when updating resulting in a brick. The problem is the update file itself..

I got a working 5.50 GEN-A [Full] and 5.50 GEN-B updates that fully work, tried and tested it last night and got it working on my PSP Slim Star Wars Edition running 5.00 m33-6..

I updated to it trying to see if that Hannah Montana: Rock Out the Show game would work but still it didn't so i went back to my 5.00m33-6..

Anyway, there is news that 6.00 OFW is coming out tomorrow, the 10th of Sept. Now let's just see if it's real and hopefully the M33 guys would come out with an upgrade to their 5.00...

this shit fucked up my psp too i put gen A in my 2001 i fucked up right pleas i need help bad it shuts of when i turn it on can you help me fix this
