iPhone 6s after tristar change no power
hello everybody! i had an iphone 6s for repair, it was discharging by doing nothing and found out that tristar chip was hot. i replaced tristar from iphone 7. now it is not booting, vcc_main shows the same as the battery voltage, charging takes max 0.1a. now nothing heats up after tristar change. pls help, is this short, or what? becouse nothing heating up.
Is this a good question?
