We can always hear that iPhone reports iTunes error 4013. This issue is common to the iPhone 6S to iPhone 7 Plus. Today we are going to talk about the iPhone 7/7P stuck on white Apple and then restart; when we use iTunes to flash it, it reports unknow error 4013. What cause this porblem? Vip Pro Shop Team analysis is as follows
Flash iPhone with iTunes and then it
reports unknown error 4013 common fault is usually caused by iPhone baseband CPU and
19.2 crystal oscillator.
To find out if the baseband caused the
problem, you can replace the new iPhone baseband CPU, and the brush it again, see if iTunes
will reports unknown error -1. If it does report an unknown error -1, this
indicates that the original baseband damage caused that problem.
To determine whether it is a 19.2M problem,
you can directly replace the new 19.2 crystal oscillator, and then use iTunes
to brush it again.
Also, if the baseband power supply was damaged, the iPhone will show same issue.
