Thank god that actually worked. My iphone 6 while trying to update to ios 12 would go into recovery mode and not come out of it. Then i would get it into DFU only for it to reboot and turn on half way through while updating on itunes. I couldnt even force the update ota because the ‘checking for update’ would just spin and think but not freeze. This is the only option that has worked! Thank you and kudos to you!
