So I have a Note 5, and it was almost dead, I hooked it up to the charger and all was going well. Last time I looked at it, it was at 67% charged. I go take a shower, come back, look at it and it's dead. No lights. Wont charge. Wont power up. Wont hard reset. I took it to a local shop. First they tried to swap the battery, then the charging circuit, then a few other things they never bothered to mention to me, before saying it's the main board and they can't fix it. Maybe, maybe not. I know they were a bunch of amateurs that made a bigger mess of my phone before they worked on it. But ignoring all that. Does anyone have any ideas on what it might be and if it is fixable. I've never heard of a phone just totally die like this, so I'm hoping there is hope and their incompetence is why they couldn't fix it.
