What to do if iPhone 7 is stuck in DFU mode?
I have an iPhone 7, and it got the black screen of death a while ago. I tried everything to reset and fix it, but nothing worked. I then put it DFU mode, and now my Mac can find the device. However, the Mac cannot update it for some reason. The progress bar will tell me it is "Waiting for iPhone...". Any help, or should I assume it's a hardware issue?
