iPhone 7 No Service Error -1
I have an IPhone 7 stuck on itunes logo. Before this the phone having a No Service issue. Then I started to restore the device, but then after restore the itunes came out with error -1 (stuck itunes logo).
I believe that error -1 or No Service issue need to reball the BBCpu chip.
Okay my question is, what if after I reball the BBCpu chip the issue not solved. Then what should I do next ?
