How to fix iTunes error 4013?
I've already replaced the battery and the Charging port with the sound port. I'm still getting this error and want to know what exacttly is broken. I really think it's the Logicboard because i've tried quite everything whithout luck. I hope anyone with the same error can help me out. Also if i try to restart the iphone it causes a respring loop. It's not Jailbroken and on iOS 9.2. When its powering on it goes off after a few seconds and starts again. If you know whats causing this let me know. Thanks in advance.
