Hi. I've encounter a problem in my iPhone which is the phone keeps searching for network. I searched the internet and many people recommend me to restore it. When i want to restore I cant because i cant turn off my Find My iPhone in iCloud. I decided to make it in recovery mode. The restore started but it stuck at abt 70% and stating there an unknown error has occurred. Error 1669. Now my phone is stuck in the recovery mode... Anything can help me? My phone is still under warranty by Digi and this is the new phone replaced by Digi and i just used ot for only 2 weeks. Thanks.
