No usb after tristar change

I have iphone 6s dead and testing battery connector I realised charging voltage was abnormal 630mv plugged in dc power supply and on prompt to boot draws 230 ma instantly. I suspected tristar and removed it. Now after replacing charge voltage is 3.7 but when power on phone it hangs on apple logo and usb is not detected in recovery mode

Ответ на этот вопрос У меня та же проблема
