i got my extra apple chip i had and i un solder ever wire 1 by one on his and solder it on the new chip in the order that was unsoldered and looked over it makeing sure i didnt bridge any solder didnt see any so i put the system back togather and now it wont even read games it likes the lasers not even working so i think if i unsolder the chip and hes just going to buy a no solder cause he dont want to spend another 100$ for a new chip and to get it solder and he says the no solder will prob me more relibale on working
