How to block iOS 15 updates
When you are expecting a new jailbreak to come on iOS 15 the best idea is to stay as lowest as possible with the firmware. Apple forces iPhones to upgrade but there is a simple solution to block iOS updates using a tvOS profile on no jailbreak devices.
Block iOS update
I will take you through the pseudo-install process of the iOS tvOS profile to disable OTA updates on your device. No jailbreak is required. Installing this profile is very easy and most importantly ensures you that the firmware will not be updated. Works with iOS 14 and iOS 15.
Step 1. Tap on no-ota15.mobileconfig from Safari on your iPhone or iPad.
Step 2. Select "Allow" when prompted "This website is trying to download a configuration profile.." to allow the download of the tvOS profile.
Step 3. Review the newly installed profile from the Settings app and tap. A new Profile Downloaded section will appear and tap on it to continue.
Step 4. The Install Profile of the downloaded tvOS 15 Beta Software Profile will be opened. It should be signed by AppleCare certificate.
Step 5. Tap Install and enter your passcode if prompted.
Step 6. Confirm installation of the tvOS profile by tapping the Install button again.
Step 7. Restart your device when prompted to apply changes and turn off iOS updates.
The firmware updates on your device should be now disabled. Confirm this by opening the Settings app and navigating through the General → Software Update sections. If it shows that "iOS is up to date", the profile is successfully blocking iOS updates.
Remove the iOS 15 tvOS Profile
To enable iOS updates again follow the steps to remove firmware update blocking. Be aware that by removing the tvOS Profile you may unintentionally update iOS to a higher firmware, and be unable to jailbreak in the near future. Apple is fixing security issues in the latest releases.
Step 1. Open the Settings app.
Step 2. Open General → Storage & iCloud Usage → Manage Storage and delete OTA data.
Step 3. Navigate to General → Profile and Device Management.
Step 4. Select the tvOS 15 Beta Software Profile.
Step 5. Tap on the Remove Profile button.
Step 6. Enter your passcode when required.
Step 7. Confirm the uninstallation by taping again Remove.
