Ok I have been doing some reading for the last little bit, and pretty much have everything down I think. I have no way of getting one of these datel batteries. Or at least couldn't find any not even on ebay or amazon. So I am going to hardmod, I just want to know if I can revert back. By running the software in one of the tutorials and re flash the eeprom on the battery? Is that the only way or would that even work? EDIT: I have one of the psps from back in the day when it came factory flashed with 1.5 stupid me had to get the internet browser lmao.
