Xbox Account download Issue (Xbox 360 and backwards compatibility)

Xbox 360 Profile Sign-In Issue

I’m having an issue signing into my Xbox 360 profile. The problem is happening both on my physical Xbox 360 and when I play Xbox 360 backward-compatible games on my Xbox Series X.

My Microsoft/Xbox account itself works normally on the Xbox Series X, but the Xbox 360 portion of the account will not sign in properly. When I try to download my Xbox 360 profile, it starts downloading and then fails with error code 8015190A. On my physical Xbox 360, I have also received error code 8015D000.

So far I have tried the following:

• Deleted the Xbox 360 profile and attempted to redownload it.
• Verified that I am using the correct Microsoft account email.
• Changed my Microsoft account password to make sure I was using the correct credentials.
• Tried signing in with two-step verification turned off.
• Turned two-step verification back on and generated an app password specifically for the Xbox 360.
• Tried signing in using the app password instead of my normal Microsoft account password.
• Cleared the local Xbox 360 storage on my Xbox Series X.
• Attempted to redownload the Xbox 360 profile again after clearing the local storage.
• Confirmed that the same Xbox 360 sign-in problem occurs on both my physical Xbox 360 and the Xbox 360 backward-compatibility environment on my Xbox Series X.

The Xbox Series X itself signs into my Microsoft/Xbox account normally. The problem only affects the Xbox 360 profile and Xbox 360 services.

Because the same error occurs on both an actual Xbox 360 and on Xbox Series X backward compatibility, I believe this may be an account-side issue with my legacy Xbox 360 profile or authentication data rather than a problem with either console.

I need help checking or repairing the Xbox 360 profile/authentication information associated with my Microsoft account so I can download and sign into my Xbox 360 profile again.
