How to downgrade to 1.50 from the Recovery Menu - GSM-Forum

..::Angel::.. · 12-23-2008, 11:10

This can be used to fix your PSP if it Semi-bricks, as long as you can access the recovery menu.

Download and Extract the RECOVERY folder

http://www.zshare.net/download/recovery-rar-ar7.html

Copy the RECOVERY folder to PSP/GAME/

Start your PSP in Recovery Mode, then choose "Run program at /PSP/GAME/RECOVERY/EBOOT.PBP". Read the instructions and press x. This will Downgrade your psp to 1.50 version. Don't shutdown the PSP or remove the memory stick until the update is finished.
Once finished, shutdown the psp and restart manually to 1.50.

The only suggestion that I can make my self is that is there a possibility that something is wrong with Maya installation ?000-076 I mean cause of the conversion from rpm to Deb or what so ever, is the a chance !!000-081 that it is Maya that is not understanding it's paths, And paths are in fact working properly,000-083 Since I am adding some echo commands to the Env and I can see them working when I get a console !!
