Days ago i was charging the iphone with an att car charger using apple usb cable without problem, it was disconnected for a few minutes but when i plug it again nothing happened (no charging) i was not worry thinking my port charger probably was dirty. As soon i get home i clean the port charger, my battery was almost at 10% so, I connect the iphone to the wall charger and nothing happen. No sound, no charging. I tried with a different usb cable and same. I make a hard reset and the iphone never boot again. It stuck in white screen with apple logo for few minutes, then turn off itselft for a second and again white screen with apple logo, that happened till battery was dead. It show low battery i plug to charger and it never charge the battery. I opened the iphone to charge the battery with an external battery tester/charger. First it show 2.67v after few minutes it show 4.0v Placing back the battery the iphone won’t boot, stuck again in the apple logo. I tried to connect the iphone to my pc to make a restore but it was not detected. Tried to put in dfu and nothing happened. 2 times it was into recovery mode but iphone isn’t detected, iphone can’t put in dfu for some reason. Was thinking in port charger becuase it won’t charge and it’s not detected by itunes. But everytime that it’s off if plug the usb cable the iphone turn on. What could be the reason that my iphone won’t boot, won’t charge and iTunes doesn’t detect. Could be the Charging usb IC U2 the problem ? Why it won’t boot? Anyone? Any help will be appreciated Ps: English isn’t my firts lenguage,
Check out your iPhone’s cable and wall outlet by connecting them to other iPhone of same model and if both are working fine then you need to clean your charging port of device. This guide is good to do that: http://www.pingzic.com/iphone-wont-charg… If nothing work then try a hard reset of your device by pressing and holding power and home buttons until you see Apple logo on your screen, this doesn’t need any iTunes connection but it can only be done if your device is on.
