restoring from backup fails during updating firmware
My iPhone 7 keeps losing carrier signal. I'm in an area with good coverage. A restart was fixing the problem temporarily but now it won't fix the problem. I have tried to restore from backup but it times out during restoring firmware. My iMac and iTunes are up to date. Multiple tries, after restarting my computer won't get beyond this point in the restore.
iPhone 7, iOS 11.1, null
