accidentally restored xbox to factory settings

For in-game account issues you should contact the game developer's support. Keep in mind that Fortnite is not part of play anywhere games.

Yeah this is the way I have been trying and failing. I think the machine is just done. I might have to just get him a new one.

Thanks for your help though

Sure, sorry I couldn't help resolve your issue!

You can factory reset by:

1) Go to System Settings > Console Settings

2) Make a note of the Console Serial number under System Info

3) Go to Memory and press Y

4) Select Format (Make sure you don't leave anything you don't want to be deleted on the console.)

5) Enter Serial Number, and you should be good!

Note: this will not delete your gamer profiles, game saves etc. So you should have no issues getting them back from the cloud. You might not need to enter your serial number, depending on the model of your console.

Hope this helped! If this is the method that you tried to use and didn't work, you might need to contact the Xbox support team, as I'm fairly certain this is the only way to do it.

I'm about to sell my Original Xbox and all games/accessories as an eBay lot.

How can I erase all personal information form my device to protect my Xbox Live account information as well as other content on the device.
