When it comes to the update of the iOS system, it has always been a pain point for the majority of users. In order to further improve the installation rate of the new iOS system, Apple always finds ways to let users upgrade, such as annoying upgrade pop-up prompts, updates for obsessive-compulsive disorder, and so on.
In order to solve Apple's "riot" operation, many users will install a shielding system update profile on their iPhone devices to completely block the update prompts of the iOS system.
For example, before everyone installed the tvOS 14 profile to block the system update, but because the tvOS 14 file due to the expiration of the certificate, the user wants to install normally, first set the adjustment system time, relatively troublesome. Moreover, the tvOS 14 profile is about to expire on January 30, 2022, and once it expires, it will completely lose its blocking function.
But the problem is not big, because the profile of the latest shielding system update has finally come ~ We installed the latest tvOS 15 profile on the iPhone, and we can continue to block the iOS 15 system update.
The method of blocking the update profile installation is also very simple, as long as you send "Block" in our public account: Fruit Powder Home, get the latest iOS 15 system shield update profile.
Copy the link to open in the Safari browser, install the latest tvOS 15 blocking profile and restart your iPhone.
After the restart is complete, we open the settings on the iPhone again - Universal - Software Update and we will find that the current iOS system is already the latest version.
After small series of tests, iOS 14 and iOS 15 can perfectly shield the system system update, iOS 12 and iOS 13 should also be OK, low system partners can try ~
In addition, the effective date of this shielded update profile will last until January 31, 2023, that is to say, after installing this new shielded profile, you don't have to worry about the system automatically updating within 1 year, as for a year later, there will be a new shielding system update file, and we will share it when the fruit powder home is ready
It should be noted that the small partner who has installed tvOS 14 on the previous iPhone needs to uninstall tvOS 14 before installing the latest tvOS 15 description file.
There may be many small white fruit fans curious, why can tvOS files block iOS system updates? In fact, the principle is very simple. iOS and tvOS are two different systems, and only a few codes can be shared, but most of them are still not available, and the system's OTA upgrade packages cannot be shared.
Therefore, installing a tvOS profile on an iOS device can make the system mistakenly think that it is checking for OTA updates for tvOS, so the update cannot be received on the iOS system
If your iPhone has installed a description file that shields updates or has a little red dot for updates, it may be that your iPhone has automatically downloaded the latest system firmware, you need to open the settings - universal - iPhone storage space - delete the system update firmware that has been downloaded.
The above is the small editor (fruit powder home) to share the shielding system update tutorial to everyone, quickly share the latest shielding system update description file to your side do not want to upgrade the system of the small partner it ~
