Why did you rename the ofw eboot to 6.35? You only usually do that when downgrading. In order to update you need to rename that eboot to just..well eboot and shove that into X:/PSP/GAME/UPDATE and then update your psp either by going to game and clicking it or going to system update and upgrading from STORAGE!, then all you need is the 6.35 pro-b eboot, you can get rid of the update
