iPhone screen black, DFU mode recognised in iTunes, still dead
I bought a second hand *defect* iPhone 11 Pro Max of eBay. The listing indicated that the phone doesn´t turn on or charges and won´t be recognised by iTunes. After receiving the phone I did a few tests. The screen doesn´t show anything and the phone doesn´t blink or show any indications that is turned on. Neither while charging. However, the first attempt to put the phone into DFU mode worked and it got recognised by iTunes. I chose the restore option and left the computer. It could not have been finished by the time I got back a few minutes later. To my surprise, iTunes was closed and there was no indication of anything. So I suspect the USB connection got lost. I tried to exit the DFU mode and put it into DFU mode again but it won´t show in iTunes again. I think it´s a good sign that it showed up in the first place. I guess I am stuck somewhere now. What´s your suggestion before attempting any hardware replacements. Cause I think it could very well be a software issue.
Is this a good question?
