FAILED TO SYNC USER DATA

I have a couple steps for you, first off, complete a hard rest following the steps below exactly as I’ve written them : Hold the power button on the console for 8 seconds or until the power shuts down completely. Unplug
the power cord from the back of the console for 5 minutes. Plug the power cord back in and restart the console.

If this does not work then do a factory reset, following the instructions at th link below, and choosing the “keep my games and apps” option.

Give both of those things a try and then let us kmow how it goes. Cheers!

Hi Gavan.

My name is Mauro and am glad to assist you. We are really sorry for this inconvenience.

First try a manual reset:

Hold the power button on the console for 8 seconds or until the power shuts down completely. Unplug the power cord from the back of the console for 5 minutes. Plug the power cord back in and restart the console. If the problem persist try the steps below:

1. Press the Xbox button  to open the guide.
2. Select Profile & system > Settings > System > Console info.
3. Select Reset console.
4. On the Reset your console? screen, you'll see three options and select the one below:

Reset and keep my games & apps. Use this option as your primary choice when troubleshooting. It resets the OS and deletes all potentially corrupted data without deleting your games or apps. In some cases, if a corrupt game file is causing the issue you're troubleshooting, you may have to choose Reset and remove everything, but you should always start with Reset and keep my games & apps.

After you select this option, your Xbox console begins the process of erasing the selected content and resetting itself to the default settings.
