Only charges when turned off.
I'm currently doing board level repair on it, replaced the transceiver for cellular service, fixed no service / service provider crash issue.
Now the issue I am having now is it only charges while off and not while it's on.
While it's off it's 0.4A.
It was working before. Charging died after transceiver repair. Replaced Tristar and now am at this issue?
Could this be replacement Tristar being faulty?
Had to rebuild audio Ic circuit as components moved around when removing the metal shield for it but fixed that okay.
Tried another charging flex and battery.
What's strange about the phone is that it will not boot up without charging cable plugged in.
So I would have to unplug battery, then plug back in and plug charging cable in for it to boot.
Seems to be no Sim card install message being spammed on this phone, probably going to give up on this one.
