iPad shows battery and plug icon when already plugged.
I have a iPad 4 to work on, the digitizer has already been replaced. The problem is, the iPad shows the red empty battery with the lightning cable at the bottom. Even when it is plugged, it still ask to plug the device to charge it. I tried to go into recovery mode on iTunes and it won't work at all, iTunes won't recognize the iPad. Anyone has an idea what could the problem be, I would like to try everything possible before needing to remove the digitizer.
Here is a picture:
I get this even when it is plugged which is weird because it should only show the battery and not the cable. Also, the screen flash every 5 sec before going back to the battery/lightning cable icon.
