Hi guys, I have updated my PSP firmware to 3.52 M33 and im having issues playing some games (.cso file, Ghost recon to be exact) and everytime i try and run it, it just goes to a blank screen and doesnt go any further than that. i have been told by others if i boot up in recovery mode and enable the 'no umd' option, this should solve the problem but i dont know for the life of me how to boot up in recovery mode. Im sure its something easy and it might be a silly question, but i am stuck and i need help. even the 007 game i was able to use on 3.40 firmware does the same thing too now. Can anyone help me out please?
