So I’m an idiot who finally caved and updated to iOS 11 yesterday. It’s not bad and I can see myself enjoying it once the kinks are worked out, but the battery life isn’t quite there yet and I’ve noticed some stuttering, amongst other hiccups. I want to revert back to iOS 10.3.3 but apparently I didn’t have the backup saved in the cloud as I had assumed I did and so now I need to get to a desktop and go the iTunes route via an IPSW download. The process is simple and I know how to do all that, but is it safe to download and install files from places like ipsw.me? My warranty on this 6s is expired anyways, so that’s not a worry. Or does anyone know any tricks to revert back to 10.3.3 with no backup and a computer not currently present?
