My psp version is 3.10 OE-A and i tried to upgrade it to 3.40
I follow the tutorial, copied the oeupdmaker and oeupdmaker% to my PSP/GAME folder and copied 150.PBP and 340.PBP file too.
When I go to the game menu in my psp, i found 3.40 OE-A Firmware Install , 2 Corrupted Data and 3.40 OE-A Update Maker, I chose Update Maker and it says The game could not be started (8002014C).
Can someone help me??
