i have a original psp, it was a 2.0 when first purchased. i had downgraded it to 1.5. i have some homebrew games, emul's etc... I wanna be able to keep it at 1.5 but wanna be able to do what all the higher firmwares can do. i was told to get CFW 3.52m33-4, so i downloaded it now this is where im stuck, when im tryin to run M33 creator it loaded the 1.5 info but stops at 3.52, i get a error message, " pbp signature dont match " Can anyone be of any help? cause the next step is running the 3.52 update and i dont even see that.
