Infinite error loop
Can’t exit iPhone setup and cannot update watch due to setup failure (no internet connection, but have one). It’s an infinite loop of trying to update watchOS w install failure. iPhone stuck in setup mode w no way to exit. This is apparently a common old problem that’s resulted in trashed Apple Watches. My watch is useless right now as I cleared it to get new OS. Both watch and iPhone are stuck in setup mode with failure. There’s no way I know of to get out until successfully installing watchOS.
