Changed my gamertag on the Xbox One X now I can’t play backwards compatible games online.

I recently changed my gamertag on xbox one and made a longer password now when I go to play a 360 backwards compatible game on xbox one it says I have to re download profile so my gamertag will change but my password for live is too long on 360

Clear the local xbox 360 cache u der storage settings ans restart the console

Basically since you updated your gamertag you would need to redownload your profile on the 360 emulator on the One.

To do this follow these directions.

1. Load up any backwards compatible game.

2. Once loaded hit the start and select buttons (small round buttons on either side of the big xbox button on the controller)

3. This will bring up the 360 guide. There should be a choice there to download profile. Choose that.

4. Enter in email and password.

This will redownload you profile to the 360 emulator and should solve your problem.

Hi,

The 360 platform can be quite 'fussy' with passwords. I would suggest changing it to something else, no more than 11 or 12 characters without any special characters such as ~#*.

The removal of the old 360 profile is the way to go though.

If security is something that concerns you (and this is a good thing), I suggest you enable

Two Step authentication for you account.

I have the same issue - can’t play any disc based backwards compatible games (360 or classic Xbox) on either my new Xbox Series X or my Xbox One X. I was also advised that it is a known problem and with engineers to resolve but that was a month ago and still unresolved unfortunately.
