iPhone 6 Plus tristar replacement
Hello. I have iPhone 6 Plus and I replaced tristar to it. Before repair I tested it with multimeter for how mutch USB cable give power to the battery bracket on logigboard
and the volt was 0.01v and with new tristar the battery bracket gived random volts wery fast 3.50v, 2.45v 1.20v etc. Do anybody have any ideas what is going on? Before repair iPhone wasn't charging or warming at all and no powered on. Screen was black and still is. I have reflowed it without any results.
Any help would be much appreciated.
With new good battery and tristar reflowed once again the iPhone works again.
