My son's Xbox's storage was full and so it deleted some things. Trying to follow some guidance, I was advised to clear storage, which I did. This included all profiles. He is now trying to create a new profile and it pops up this message: "Couldn't sign in your profile. Please try again." He isn't trying to sign in, he is trying to create a new profile. Any help would be awesome! Thanks!
This has happened to me, nothing I tried worked other than restoring factory settings. Just be sure to store anything like save files onto a USB/Hard Drive first!
