also i can not reset it back to the pervious value it seems to have broken at 1.4billion
if it is a minus value it will still hit max damage but with sazh u have to use a9 a9 a9 to be able to hit max damage
well ive never done it but by the looks of it the hardware point of view seems easy its just mainly aloud of soldering so if u can solder and have a electonic no how then its worth doing yourself
