How long does it take for your gamertag to update?

That means your change did go through, but you now have a "classic" gamertag and one that falls under the new gamertag policy. That usually happens if you choose different characters for your new name, but for some reason it does that randomly in other cases. You can try changing your tag again to see if it shows the option to change each on independently (you don't have to go through the whole change to see if it shows that option).

Thank you but it didnt work and i tried holding the buttons as instructed and nothing there happened either. To be honest i regret buying this machine. I bought it just over a year ago and was fine and then it needed to do an update which didnt work
which is why i packed it away. I was advised to update by usb at the time, but do not have a windows pc as i am apple mac.

Hi try power cycling the console. Maybe turn it off and unplug it for 10 seconds before trying again

E105 can be fixed by restoring your console. Follow these steps.

Restore your console to factory defaults

If resetting your console does not correct your startup error, you can use the Xbox Startup Troubleshooter to completely restore your console to its factory settings.

Warning Resetting your console to its factory defaults erases all accounts, saved games, settings, and home Xbox associations. Anything not synchronized with Xbox Live will be lost. You should only use this option as a last resort.

If you need to bring up the Xbox Startup Troubleshooter again, follow these steps:

1. Power off your console, and then unplug the power cord to ensure that the console is completely powered off.
2. Wait 30 seconds, then plug the power cord back in.
3. Press and hold the BIND button (located on the left side of the console) and the EJECT button (located on the front of the console), and then press the Xbox button on the console.
4. Continue holding the BIND and EJECT buttons for 10-15 seconds.
5. Listen for two “power-up” tones a couple of seconds apart. You can release the BIND and EJECT buttons after the second power-up tone.
6. The console should power up and take you directly to the Xbox Startup Troubleshooter.

To reset your console from the Xbox Startup Troubleshooter, use the D-pad and A button on your controller to select Reset this Xbox. When prompted, select Remove everything.
