First solution: Make sure you have a stable Internet connection

The ‘Unable to Install Update’ error may occur if your iPhone does not have a stable internet connection. It’s because your device will have to download a large amount of data and any issues while the download is underway may lead to this problem. 

To make sure your iPhone has a stable internet connection and if you’re using WiFi, simply disable the WiFi connection for a few seconds, and then re-enable it after that. Your iPhone will try to reconnect to the same network and once it has successfully reconnected, browse some sites to confirm that you have a stable connection. After which, try to download the update again.

Second solution: Force restart your iPhone

The next thing that you have to do if the ‘Unable to Install Update’ error continues to show up even if your iPhone has a stable internet connection is the Forced Restart. What it does is refresh your device’s memory and reload all its applications and services. It is possible that this problem is caused by a minor firmware or software-related glitch, that’s why you need to do it as it’s pretty effective in fixing issues like that. Here’s how it’s done: 

  1. Quickly press and release the Volume Up button, and then the Volume Down button.
  2. The moment you release the volume down button, press and hold the Side or Power key for 15 seconds or until the Apple logo shows on the screen. 

Once your iPhone has successfully rebooted, try to see if the problem is fixed and that your device can successfully install the new update. If still not, then move on to the next solution. 

Third solution: Delete downloaded update and redownload

If the ‘Uninstall to Install Update’ error showed up after a few minutes of downloading the update, then there’s already some files and data that have been saved in your iPhone’s memory. It’s also possible that the download process was interrupted and your iPhone can no longer continue the previous download. To rule this possibility out, delete the downloaded update and re-download it. Here’s how it’s done: 

  1. From the Home screen, tap Settings. 
  2. Touch General.
  3. Select iPhone Storage.
  4. Locate the iOS software download in the list and tap on it.
  5. Select Delete Update and confirm you do want to delete it.

Now, try to see if your iPhone can successfully download and install the update after doing this.

Fourth solution: Make sure your iPhone still has enough storage space

Now, here’s one of the most important things that you should remember in case you’re one of the users that have issues downloading the new firmware update. Your iPhone must have at least 3.5 GB of available storage because the new update is around 3.3 GB. Your iPhone does delete user files automatically even if it’s running out of storage space. You have to do it yourself. You may uninstall unused apps, delete files that are not important, delete some of your videos, pictures, music tracks, etc. 

If you don’t know which files or data to delete, sync your iPhone with iCloud or create a backup using a computer. After that, reset your iPhone and before you restore all your files and data, download and install the new firmware update first. This is how you reset your iPhone: 

  1. From the Home screen, tap Settings. 
  2. Find and tap General. 
  3. Scroll down to the bottom of the screen, and then touch Reset. 
  4. Tap Erase All Contents and Settings. 
  5. Tap Erase Now. 
  6. If prompted, enter your security lock. 
  7. Tap Erase iPhone at the bottom of the screen.  
  8. Tap Erase iPhone again to proceed.  
  9. Now enter your Apple ID password, and then tap Erase to proceed with the reset. 
  10. Wait until your iPhone has finished the reset, and then set it up as a new device. 

If the ‘Unable to Install Update’ continues to show even after the reset, then download iOS 13 via iTunes using a PC or Mac and then update your iPhone using iTunes. Or, you can restore your device first and install the update later.
