Most of us, except those that are very new to Apple and iOS, know that, when a new version of the firmware is released, there will be problems with it. iOS 10 is living up to that already with quite a few reports about update errors stalling users when they attempt to upgrade. The error message that people are seeing says, “This device isn’t eligible for the requested build” and is effectively locking people out of their devices, as they cannot get past the message. If you have this message on your iOS device, try one of these solutions.

Fix “Device Isn’t Eligible for Requested Build” Error :
Try these solutions in the order that they are written. Not all will work for everyone and you may need to work through the list to find one that works for you:
Update iTunes :
This is the first step before you do anything else:
- Open iTunes
- Click Help on the menu bar
- Click on Check for Updates from the dropdown menu
- iTunes will see if there is an update; if there is, follow the on-screen instructions to update your version
Check for Updates on your Computer :
All computer operating systems will need to be updated on a regular basis, whether it is Mac OS X or Microsoft Windows. These updates may be irritating at times but they are there to keep our computers safe, secure and running optimally. Check your system to see if there are any outstanding updates and apply them before trying to download iOS 10 again [ext link]
Check Your Anti-Virus Software :
Sometimes, your anti-virus software can get in the way and hamper communications with iTunes. Check your system and, if it is interfering update it to the latest version. If that fails to clear the problem, you should consider disabling it until you have upgraded. Some people might find that they have to remove their anti-virus software altogether while they are upgrading but this is rare and it can be re-installed afterwards.
Reboot Everything :
Start by rebooting your computer and then your iOS device. Once both have restarted, attempt the update again
Remove USB Devices :
Most of us have several different USB devices plugged into our computers and these can interfere. Remove all that are not needed for the update and try again.
Edit The Hosts File :
The problem could be within the Hosts file and you will need to make a change to it if none of the above has worked:
- Open the Run box on your Windows PC and type in %WinDir%\System32\Drivers\Etc
- Click OK and an etc file will open
- Click on Hosts
- Look for com and delete it from the file
- Save your changes and Exit
- Restart your Windows PC and have another go at updating
- Close iTunes and open Terminal
- Type this at the prompt: sudo nano /private/etc/hosts and then press Enter
- Type in your login details, followed by pressing the Enter key
- Look for om in the hosts file
- Delete it or insert # and a space in front of it – # apple.com
- Press CTRL+O to save
- Press Enter when you are asked for a file name
- Press CTRL+X to exit
- Restart your Mac and try updating again
What If None of This Works ?
If you have worked your way through the list and nothing has worked you have two options left open to you – use the IPSW method and iTunes to manually update or wat for Apple to put out an update that fixes the issue.
