Was able to restore my son's Xbox One to factory settings by pressing "down-A-down-A-A" after a e200 error really quick. Then selecting "Restore to factory settings". First there was a e102 error message, but a hard reset handled that. After restoring the Xbox works just fine. Only the saved files on the harddrive and all account settings were gone, but easily brought back.
