Check if the device supports iOS 16

If the device is not compatible with iOS16, you may receive the message "Unable to install updates - error occurred while installing iOS16".

Therefore, first make sure your device is on the support list.

Release iPhone storage space

The update of iOS will take up a lot of storage space. The "update cannot be installed - an error occurred when installing iOS 16" usually pops up due to insufficient memory.

Open [Settings] - [General] - [iPhone storage space] to view the usage of iPhone storage space, and then ensure that the memory is sufficient to update again.

Check whether the network is stable

Since iOS update takes a long time, it is necessary to ensure network stability to avoid interruption of the update process, which may cause iPhone update failure.

Open [Setting] - [Unlimited LAN], and select the WiFi with better network connection.

Force iPhone restart

Forced restart can be used to repair some basic iOS system failures, including stuck black screen, recovery mode and other basic iOS system failures.

Select different forced restart operations for different iPhone models:

Full screen models (iphone 8 and later): press the high and low volume buttons quickly respectively, and then press the On button continuously until the Apple logo reappears after the device's black screen, and then release all the buttons;

Delete the updated firmware package

Delete the downloaded update firmware package to solve the problem that the update is overdue and cannot be updated again because the download time is too long.

Open [Settings] - [General] - [iPhone storage space], and find "Update" in the application list. Click Update, and then click Delete Update.

Then open [Settings] - [General] - [Software Update], and make sure to download the update package and update the iOS system again when the network is good and the memory is sufficient.

Update with professional repair tools

If the first five solutions are adopted, there will still be various iOS update errors and update failures. It is recommended to use professional tools to upgrade to the iOS16 system. The upgrade should be repaired at the same time to reduce iOS system failures.

However, the operation is relatively complex, and there are many error prompts and update failures.
