my update keeps failing anytime I want to install, I’ve deleted and downloaded it several times but it hasn’t work
update of ios12.5 for iPhone 5s
Same goes with mine.
Updating using cellular, wifi, cellular+wifi; delete and re-download update; with auto-update on/off; reset all settings; restore device; - installation failed.
I've tried download and update via iTunes but installing progress stopped at around 60% then device auto-reboot, loading stucked at Apple logo. After attempt few recovery method its getting worst, my phone couldnt be save and no longer works.
Best option, dont update and let your ios remain with that version.
