Homebrew coders Xenogears and Becus25 is back on the scene to release their own custom firmware for version 5.50. The Custom Firmware 5.50 MHU is only compatible to all PSP-1000 and PSP-2000 models except for PSP owners with TA-088v3 mobos.
To install the CFW:
And just a little note from the devs, you won't be able to run games using Sony NP9660 driver in this version so for the mean time, use the M33 driver instead. These problems will be fixed in the future update so stay tune.
- Copy the UPDATE folder into PSP / GAME
- Copy the FW 5.50 in the UPDATE folder and rename it SCE.pbp
- Start the application
- At the end of this update, when prompted, press x to restart the console
