iPhone 4s won't activate even with sim on a 3g activated country
Literally that, it was my grandmothers iPhone 4s, it didn't have icloud it was working perfectly i just decided to save a backup on iTunes windows and restore it with the last update to see what it was like to use that phone today. It won't activate, now it's on an activation loop, doesn't matter if i try to activate it on windows with iTunes, macOS Sequoia finder or macOS Mojave iTunes.
