I recently dropped my iPhone in water and it was working fine right after that, but the next morning I was prompted with an ‘activation required’ screen.
I’m afraid ‘activating’ will wipe out everything on my iPhone, so I’m trying to back everything up before doing that.
However, both iTunes and a third party tool called iMazing won't let me back anything up before activating.
I know that none of the data has been affected by the water because (a) it shows up in iMazing and (b) the lock screen still has my old wallpaper, language settings etc.
So, 2 questions: does activating my iPhone restore it back to factory? And how can I backup my iPhone without iTunes on Windows/Mac/Linux?
