IPhone cannot be updated. What should I do if I have the official version of iOS 15 or encounter problems?

If IOS 15/iPadOS 15 system encounters problems when upgrading on Apple mobile devices, you can refer to the following information to try to solve them:

1, no update push received:

Please ensure that the device supports updating to iOS 15/iPadOS 15.

Check whether there is a beta description file: users who upgraded to beta before need to go to Settings-General, click Description File and Device Management, delete the beta description file and restart the device, and then check the update in the software update.

2. If there is not enough space to update:

If there is not enough space to download and install updates, the software on the device will try to make room. It will only remove downloadable application data, and will not remove or relocate any of your data.

However, it should be noted that if the storage space is full, the problem of white apples will easily occur during the upgrade process, resulting in data loss. To avoid this unexpected situation, please make sure that your device has enough storage space.

You can remove unused content and applications from your device to make room for updates. You can go to Settings-General-[Device Name] storage space to check.

3. If it takes a long time to download the update:

You need an Internet connection to update your device. The time required to download the update varies depending on the update size and network speed. You can use the device normally when downloading the update, and then the device will inform you when you can install the update. In order to improve the download speed, please avoid downloading other content and use Wi-Fi network as much as possible.

4. Prompt that the update server cannot be connected or the update cannot be verified:

When you try to update the device, you may see one of the following messages: Unable to check for updates. An error occurred while checking for software updates. Or the update cannot be installed. You need to access the network to update.

When the above prompt appears, try to update your device again using the same network. If you still see one of the above messages, please try to update your device with another network, or update your device by brushing. If the problem persists after trying to update using multiple networks, please delete this update and try to download and install it again.

5. If the update cannot be completed.

When installing updates, the progress bar may move slowly. The update time varies depending on the update size and the number of files on the device. To update wirelessly, make sure that your device is always connected to the power supply. If the device runs out of power, connect it to the power supply, and then turn on the device to complete the update or recovery.

If you still can't install the latest version of iOS or iPadOS, try downloading the update again or updating it through your computer:

Enter Settings-General-[Device Name] storage space. Look for updates in the application list. Tap Update, then tap Delete Update. Go to Settings-General-Software Updates and download the latest updates.

If you can't see the update in the application list, or if the problem appears again, you can try to update the device on your computer through the one-click brushing function:

Open the PC (need to update to the latest version) and connect the iOS device to the computer. On the one-button screen, select iOS 15, check the option of keeping user information, click the screen now and wait patiently for the screen to complete.
