Okay, a year or so ago, I flashed my PSP to Dark Alex's 3.02 OE-B Custom Firmware, and then to 3.03 OE-A. I want to restore the original Official Firmware, like 2.71 or 1.50. This is a TA-082 Motherboard PSP. I can't find any information at all about reverting to official firmware. I want to be able to update to the Sony 3.72 Firmware. Anyone have any information they can share on how I would go about doing this? I would be super grateful. Thank you.
