[Question] What does the app do to block updates

[AymenKcm1]

I wanted to know what does the app do to achieve the blocking: Does it modify the hosts files / disable the update service on iOS or something else ?

TIA

I want to know the same. I have restored from a backup of a jailbroken phone (u0, mikoto, iCleaner Pro) and now when I tap Software Update, the menu remains highlighted and the Settings app hangs. (I would like to re-enable OTA)

It does effectively the same as installing a tvOS 16 developer beta profile does: https://github.com/haxi0/KillMyOTA/blob/master/KillMyOTA/BlockOTA/Blocker.m#L24-L30. It may be possible to undo by just installing and then uninstalling any beta profile.

unc0ver and iCleaner Pro make other changes as well. Deleting these files from an iTunes/Finder backup using iBackupBot, iMazing or iPhone Backup Extractor should re-enable updates blocked using all currently known methods:

/var/Managed Preferences/mobile/com.apple.MobileAsset.plist
/var/MobileAsset
/var/mobile/Library/Preferences/com.apple.MobileAsset.plist
/var/MobileSoftwareUpdate
