If you’re trying to update iOS to the latest version on an iPhone, iPad, or iPod touch and you get an error in iTunes saying:

The iOS Device “Device Name” could not be updated. This device isn’t eligible for the requested build.

You’re most likely encountering one the following problems: either you are using an old version of iTunes, you are using an incorrect version of the firmware for your device, or you have gs.apple.com re-routed or blocked in your hosts file.

How to Fix “This device isn’t eligible for the requested build” Error in iTunes

First let’s cover the iTunes and firmware aspect, then explain hosts modifications. Try these in order, one of them will likely fix the ineligible build error:

Wait, Then Re-try Updating iOS

Sometimes a little patience is sufficient to remedy this error message. Try waiting a little while and then attempting to download and reinstall iOS again, it often works.

1) Update iTunes

This is easy, just open iTunes and update to the latest version. This is required because the newest version of iOS require the newest versions of iTunes. Easy to resolve.

2) Use Proper iOS Firmware

The next thing you need to do is make sure you’re using the proper firmware IPSW file for your iOS hardware. You can download any firmware files from these links:

• iOS IPSW firmware files are available to download here

For example, if you have an iPhone SE, you must use IPSW firmware matching that device.

Additionally, you must use a version of iOS IPSW that is being signed by Apple. Older versions of IPSW are usually not signed.

A fair amount of confusion regarding older IPSW seems to be in the difference between GSM and CDMA downloads, in the USA this is easiest to determine based on the cellular provider: AT&T is GSM, Verizon is CDMA. If you’re not sure what to do with an IPSW file, you can read our walkthrough of how to use them.

If you’re certain you have the correct firmware file and you’re still getting the “device isn’t eligible” iTunes error, it’s almost certainly a result of gs.apple.com being blocked in the hosts file.

3) Remove the Hosts Block

If you know you’re using the proper iTunes and iOS version and you’re familiar with editing a hosts file, just throw # in front of the “74.208.10.249 gs.apple.com” entry and you very well might be good to go. If you have no idea what that means, read on and it’ll be explained easily.

This usually comes from users who have jailbroken an iOS device at some point on their computer, or did the error 3194 fix, and as a result have a line in their hosts file blocking Apple’s servers. There’s two ways to fix this:

Manually Editing Hosts

• Quit out of iTunes
• Go to the hosts file. For Mac OS X this is located at: /etc/hosts or /private/etc/hosts and in Windows it is located at: c:windowssystem32driversetchosts
• Open the hosts file with Administrative privileges so that changes can be made and saved (eg: sudo nano /etc/hosts)
• Look for a line that resembles something like this:

74.208.10.249 gs.apple.com

• Put a # in front of that to comment it out, making it now look like this:

# 74.208.10.249 gs.apple.com

• Save the hosts file
• Flush DNS cache and restart iTunes

Using TinyUmbrella
TinyUmbrella prevents you from having to use the Terminal to edit system files, instead you can just launch the app and quit it. TinyUmbrella is third party software and is not verified, use it at your own risk.

• Download TinyUmbrella for Mac OS X (direct download link)
• Download TinyUmbrella for Windows (direct download link)

After you’ve downloaded and installed TinyUmbrella, here’s how to use it to remove a hosts block:

• Open TinyUmbrella and click on the “Advanced” button tab at the bottom
• Uncheck the box next to “Set Hosts to Cydia on Exit”

Now quit out of TinyUmbrella and the app will modify the hosts file in the process to remove the block, allowing you to connect to Apple’s servers again. Before you try though, be sure to turn the iPhone, iPad, or iPod touch on and off again, and relaunch iTunes as well.

If you still run into problems, you may need to flush the DNS cache as well. Quit out of iTunes and open the Terminal in OS X Lion, then type:
dscacheutil -flushcache
Now relaunch iTunes and you’ll be good.

Whichever approach you took, this fixes the “eligible build” error and the iOS device will update as intended.
