iphone 6 died after new battery
This is your student Tomer from Israel in the course, I would be happy to consult
IPhone 6 dead will not turn on
A battery was replaced and sometimes it turned on and now it went out again and died
Where to begin?
Some sites do you recommend to solve such problems and have Schematic? For starters that would be free please?
Well, with any dead iphone, the first step is to determine whether it is drawing power through the usb ammeter and/or the dc power supply, so do those two things first. If it is drawing 0A on both, then I would probably assume tristar is the problem first. If not, then plug the phone into itunes to see if it's recognizing the phone and what state it's in (DFU, recovery, or passcode screen/trust). From there, then you can start troubleshooting onwards.
