Tricks: What to do if the old tips for iPhone phone upgrade

Hello, if you want to block the upgrade tip of the software, iOS7 or above can go to Settings - Notification Center, find the application with the update tip corner, turn it on and turn off this option: "Application icon marker".

As shown in the red box in the figure below:

If you set up a system upgrade prompt, it will be a bit laborious, and there are two main methods.

Jailbreak method:

First, jailbreak your device;

Use ifile to open the directory of System Library CoreServices, find "This file is opened with the attribute tabler, click the first line, change the 11d257 (the current version number of the system) to 12a365 and restart the device;

After restarting, '1' has disappeared, and after completion, change it back to 11d257 and restart!

Methods in the non-jailbroken state:

After the verification is successful, the chrysanthemum circle will start to turn, and at this time, immediately press and hold the power and home buttons to force the boot;

After the machine is restarted, you will find that the red 1 on the settings is gone, and the occupied memory is also back;

Note: Unjailbroken users will have infinite daisy reactions when performing this method, that is, the operation may be forced to upgrade if the operation fails, so please consider it carefully before performing the operation, I personally recommend that it is best to jailbreak your device after the operation.

General Way to Cancel iPhone System Update Prompt:

1. Cancel the prompt of iPhone system update, that is, delete the update cache file completely by erasing the system content.

2. The reason why the system will automatically update and upgrade the system file is because the function of automatically updating the application is enabled, so when the device is connected to the network, it will automatically update the program file in the background.

3. If you want to delete the iOS system files of the upgrade reminder, you need to erase all the content and settings, that is, to restore all the files on the phone to the initial system state, that is, to erase the software that has been installed on the phone, **, **, **, ** and other files. So before erasing all files, back up the important files that need to be backed up, and the software can be reinstalled.

4. To erase all content, open Settings - General - Restore - Erase All Content and Settings.

5. After erasing, when you activate your phone with AppleID, you can see that there is no system prompt for updating in the settings, and there is no cache file that the system automatically updates.

6. If you want to completely prohibit the system from automatically updating files, the operation method is: mobile phone settings - iTunes Store and AppStore, after entering it, in the automatic ** project, the application and the update function are turned off, and the bottom of the use of cellular data is turned off, so that the system will not automatically update the program under any circumstances.

7. Of course, there are drawbacks, that is, the software will not be automatically updated, if you need to update the installed software to the latest version, you need to enter the appstore to manually update and upgrade the software.
