g'day mate, not sure if anyone got this issue,
my phone seems dead after bootloop few times.
I've tried hold down power button and
tried vol down+power for a min, still nothing happen on screen, there is no vibration after i press power button, so I think it wasnt about the screen issue.
it has current from my portable charger to the phone, and ive tried to charge the phone with moto z mod, so it shouldnt the battery drain issue, so it has high probability of mainboard issue, not sure if the connector goes off because of the heat issue, anything else i can go for investigate?
