Yes. Modifying Xbox hardware (RGH/JTAG, ODDE), firmware (DVD drive flash), or software (game saves, profile editors, unauthorized code) violates the Microsoft Services Agreement and Xbox Live Code of Conduct. Enforcement is automated and permanent.
| Type | Scope | Appeal |
|---|---|---|
| Console Ban | Device ID (KV) blocked from all Xbox Live services. Offline works. | None. Hardware permanently blacklisted. |
| Account Ban | Gamertag blocked. Console may stay clean. | Rare — only if error proven. |
| Communication Ban | Temp (1/7/14 days) — messaging, voice, club, LFG. | Auto-expires. |
| Marketplace / Purchase Ban | Cannot buy/redeem. Fraud suspicion. | Support ticket. |
Modding for preservation/offline is a valid hobby. Connecting a modified console to Xbox Live is a guaranteed loss of that console's online life.
