Need help: My iPhone stuck on install now screen during software update

If your iphone stuck on install now screen, DFU Mode is the deepest-level restore solution, though it may erase all your data, and you can restore from a backup afterward.

It allows you to fully reset the iPhone and reinstall iOS, but using this feature will wipe all data on the device.

First, if possible, back up your iPhone to iCloud or your computer to protect your data.

Connect your iPhone to your computer using a USB cable. Press the Volume Up button (and release it quickly), press the Volume Down button (and release it quickly), then hold down the Side button for 10 seconds. Continue holding the Side button while pressing and holding the Volume Down button for 5 seconds. Release the Side button, but continue holding the Volume Down button for 10 seconds.

The screen will remain black, indicating that the device has entered DFU mode. Open iTunes or Finder on your computer. A prompt will appear asking if you want to restore the iPhone. Click Restore to reinstall iOS.

Once the restore process is complete, you can set up the iPhone as new or restore from your backup.

This method cannot be used to fix your iPhone without erasing data, so it is only suitable when all other solutions for your iphone stuck on install now screen have failed and you have a backup ready.

If you don’t want to use third-party tools, you can try this method. This is a drastic measure, so you should think it through carefully before proceeding.
