I want to sell my PSP so I want to factory reset it to remove all my personal data but I want to know if that will screw with the CFW. It doesn't matter if I keep the CFW or not since the latest firmware is hackable so if it's not on there the buyer can just do it themselves. I just need to know the best way to remove all my user data without bricking the system, keeping CFW or not afterwards doesn't matter. Also could you suggest a price for a PSP 3000 that's in very good condition that comes with a Micro SD to Memory Stick Pro Duo adapter, 2GB and 4GB Memory Sticks, and Need For Speed Carbon?
