Hello there, I ve got an ipad 4 WIFI stuck in DFU Mode und i cant restore it. The computer still recognizing the ipad but just in DFU mode. The screen is staying black. It shows the error 4014 on itunes. On 3UTools it says “no valid Serialnumber”. And sometime it says “anable to switch from DFU mode to recovery mode”. Sometimes the ipads is trying to restart while restoring and the apple apears for a second but than disapears again. Do you guys think its a software problem or a hardware problem. Tryed running it barebone just the pcb but also not able to restore. thanks peace üt
Error 4014 could be caused by a worn cable, charge port or bad wifi. For your iPad, I would try switching cables, trying a different PC port, or replacing your charging port. I have replaced a few ports that have had the same issue and they’ve worked, but they have all been on iPhones and different iPads.
