How to block iOS updates with Block OTA Profile or OTADisabler for TrollStore

When you are expecting a new jailbreak to come on iOS 18, the best idea is to stay as low 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 your iPhone. Learn various methods to prevent iOS OTA updates, including utilizing a profile or a jailbreak tweak, accessing OTADisabler for TrollStore, or executing manual blocking through the terminal.

Please note that Apple does not mandate users to install the latest iOS firmware version. You can disable Automatic Updates from the Settings app, accessible through the General → Software Update section.

However, if you wish to prevent accidental updates on your device, you can install the iOS 17 "tvOS profile". This process is simple and guarantees that you'll remain on your current firmware version. It's particularly handy if you're anticipating a jailbreak release for an earlier version and want to avoid updating in case it gets patched.

How to block OTA with a Block OTA Profile

I will take you through the pseudo-install process of the iOS tvOS 18 profile to disable OTA updates on your device. No jailbreak is required. Installing this profile is very easy and most importantly ensures that the firmware will not be updated. Works with iOS 9 – iOS 18.

Information: On iOS 18 it may be required to install the profile from iCloud Drive. Do not tap on the no-ota18.mobileconfig file from Sarari Mobile becouse it will open it as a text file. Instead, tap on the 'Search icon' from the 'Downloads' list in Safari Mobile and install OTA Profile from iCloud.

Step 1. Tap on no-ota18.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.

How to remove the iOS 18 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.
