Block OTA for iOS 13.6 and above.
As we known, Unc0ver that is a jailbreak tool for iOS is supported iOS 11 - iOS 13.5. At present, the official version of Apple's iOS system has come to iOS 13.7, and the minimum system version that users can downgrade is iOS 13.6.1, which exceeds the scope of unc0ver's support. This means that once the device is upgraded to iOS 13.6.1 or higher, it will not support jailbreak using unc0ver.
In order to prevent the iOS system from automatically OTA upgrades, or eliminate uncomfortable digital reminders, we can block OTA upgrade for iOS.
How to block OTA upgrade?
Make sure you have deleted the downloaded update in Settings - General - Device Storage.
Open BetaProfiles.com in iPhone or iPad Safari browser, and scroll down the page to find out the block OTA profile (also tvOS 13).
Click to download and you will see the following prompt:
Tap Allow from the popup
Then follow the prompts to install tvOS 13 beta profile in Settings app and restart your device.
After your device has restarted, you will no longer receive any new iOS updates.
