Here's a tutorial on how to update your PSP custom firmware from 5.00M33-6 to 5.50M33-A then GEN-B and then GEN-B2. I updated to this firmware o that i could play Gran Turismo and FIFA 10 on my PSP. Note that you need a PSP 1000 or 2000 Model to do this and not a 3000 or Go. Here are some notes to take of - Make sure your battery is 80% or higher If the battery is low, put your PSP to charge and while charging, update it DISABLE ALL PLUGINS! Only do this on a PSP 1000 or 2000 Model Backup your Save Games (In rare cases, it gets corrupted) It is not my fault if your PSP gets bricked Here are the links to the firmwares - 5.50 GEN-A http://dl.qj.net/psp/hacks-exploits/custom-firmware-550gen-a.html 5.50 GEN-B http://pspcustomfirmware.com/downloads/download.php?file=68pspgen-cf550gen-b.zip 5.50 GEN-B2 http://www.2shared.com/file/7627482/fedfca95/pspgen-cf550gen-b2_update_VISION.html If you want to update to 5.50 GEN-D, make sure your PSP is 5.50GEN-B2 and then get the 550.PBP file and put it in the ROOT OF YOUR MMS and the update files to the PSP/GAME/UPDATE folder. Then from there, update the PSP to GEN-D and get an update to GEN-D2 and so on to GEN-D3 Note- Remote Joy works best on 5.50 GEN-D2 ENJOY!
