LG V10 (temporary) Fix: phone doesn't turn on / boot loop
Does your LG V10 or G4 boot-loop or refuse to turn on? Maybe it freezes after staring to boot? These can be caused by a design choice made by LG that results in early degradation of the solder.
This is a temporary fix that will get the phone working, if this is the issue, so that you can get your data off. YMMV
