iOS 8 Upgrade: “Insufficient storage”, “Upgrade error”, “Stuck on requested upgrade” [Troubleshooting]

At this point, two things could have happened: you have successfully upgraded to iOS 8 or you are still stuck trying to upgrade to iOS 8 on your iPhone iPad or iPod touch. Besides the very important problem of server overload preventing you from downloading the required update files, there are many other errors that could have come up.

This is for all those who are still trying to upgrade to iOS 8. If you are facing problems such as “insufficient storage space” or “software upgrade error” or if the OTA upgrade is stuck on “Requested Upgrade” for a long time, you should read the following.

1 Insufficient storage space on iPhone iPad while upgrading to iOS 8

This is the largest of all. Anyone trying to do an OTA upgrade for iOS 8, especially someone who has a low-capacity device like the 16GB iPhone 5 5c 5s, has a good chance of seeing this.

You try to do an OTA update and your iPhone tells you it doesnt have enough space (because the OTA update requires about 5 GB of free space to unpack all the stuff, back up your data, etc.)

Fix “Insufficient Storage” on iPhone while upgrading to iOS 8 :
the easiest solution is to do this:

  • Connect your iPhone iPad to your computer
  • Turn on iTunes
  • Update from iTunes.

Without access to a computer? Wait until you can be near a computer with iTunes and then upgrade. iOS 8 is large but not big enough to remove the hair from the failed OTA upgrade due to lack of space. And for people who complain about why Apple would need so much space to do the OTA upgrade, heres how it works.

If you still intend to follow the OTA route, you must delete the data from your iPhone.

2 Failed software update

What happens when you encounter a failed software update? This could be mainly due to server problems (there is still a massive overload as millions of people try to update).

Correction of “Software Update Error” when upgrading to iOS 8:

The most ideal way to solve this would be to download the IPSW files directly and install them via iTunes. Heres how to do it:
(Note: an IPSW file is basically the iOS 8 installation file)

  • Download the correct IPSW file ( choose the correct one from here )
  • Connect your iPhone to your computer
  • Open iTunes Backup of your iPhone
  • In the Summary tab, you should see the “Restore iDevice ?
  • Hold down the Shift key and click on Restore .
  • .

  • Select the downloaded IPSW file.

The iTunes restore will install iOS 8 on your device. Then, restore from backup to recover all data on your iPhone iPad.

3 iOS 8 Update Stuck in “Update Requested”

Many people who try to upgrade OTA face this problem. And unless you dont have access to a computer with iTunes, theres no point in waiting several hours just to do this OTA update. You can forget about OTA and continue with a regular iTunes update.

See no. 1 for solution. All you need to do is connect your iPhone to the computer, open iTunes, click Update in the Summary tab.

4. iOS 8 update stuck!

This can happen at both times: when you try to do an OTA update or when you try to update through iTunes. There can be many reasons, but predominantly, this could be some software problem or a server problem.

  1. Regardless of when this happens, you can always restart the update process by turning off your iPhone and then turning it back on.
  2. If the iPhone iPad does not respond (or gets stuck in a startup loop after turning it off), connect it to iTunes. Primarily, iTunes detects the iPhone in recovery mode. Yes, youll lose data if you didnt remember to back it up first. But you can restore through iTunes.
  3. If you were updating through iTunes and you get stuck, do this: force the closing of iTunes, disconnect the iPhone from the computer, open iTunes, reconnect the iPhone and restart the update.

5. Other matters

Other problems can be attributed to the problem of server overload. Despite Apples handling, the amount of traffic to which the servers are subjected is enormous. It is likely that there are problems such as “cant connect to the server” and many other generic update problems.

With problems like these, you will have to wait a few minutes and hours before trying the update again.
