with most pc's you get to the bios befor windos os even loads would there be a way to get to lets say a "dos" like program. its just an idea, since i know very little about the PSP OS other then you have very little control over this mini computor. what do you know about the OS cuz i thought about just simply remanming all the files in the EBOOT for 1.5 to i higher fake OS call it 2.54 or soemthing messing with all the anti downgrading stuff programed into 2.5.

anone know how to actuly look at the program that runs when you simply try to downgrade to 1.5.

i went to school to be an electronic tech, and in all the OS i have used they all have a back door for the tech guys so they can fix problems with in the psp. normaly at start up, maybe a difrent aproch is needed inorder to crack this. I dont think that sony would make a system that couldnt be gotten to by tech... even if it there own techs who are in the system.
