Why Deleting Mi Accounts on Redmi Note 9 Is Not Always a Trivial Thing
The Mi Account binding on Xiaomi smartphones is not just a synchronization option, but a full-fledged security system integrated into MIUI firmware. On the Redmi Note 9 model (codename merlin), this binding is implemented especially rigidly: even after resetting to factory settings, the phone may require the username and password of the previous owner. This is not a bug, but a feature called Factory Reset Protection (FRP), which Xiaomi implemented by analogy with Google.
Complicating the problem is that standard deletion of an account through settings often fails due to the error "This device is tied to a Mi Account." This is especially true for hands-on phones where the previous owner did not untie the device. In this article, we will discuss all working methods, from official to technical, including bypassing locks via Fastboot and EDL.
It is important to understand that if you are not the original owner of the phone, some methods may require proof of purchase (checks, box with IMEI). Xiaomi actively fights stolen devices, so without this data unlocking through official channels will not be possible.
Method 1: Standardly delete Mi Account through settings
If you have access to your phone and remember the password from your Mi Account, this method is the easiest and most secure.It works on the Redmi Note 9 with any version of MIUI (12, 13, 14) and does not require a PC connection.

After that, the phone will automatically log off and the account will be de-linked, but there are nuances:
- π If the phone was reset to factory settings, this method wonβt work β youβll need to enter your previous account data.
- β οΈ Some firmware may not have the "Delete Account" option. In this case, try updating. MIUI last-minute.

Method 2: Remove from Xiaomi website (if phone is blocked)
If you don't have physical access to your phone, but you remember the Mi Account, you can try to untie the device remotely.
- π Phone locked after resetting settings.
- π± Your device is lost or stolen (but you want to delete it from your account).
- π You sold your phone but forgot to untie it from your account.

- Confirm the action via SMS or email (if two-factor authentication is enabled).
After that, the phone's link to the account will be removed, but there are important limitations:
| Situation | The result |
|---|---|
| Phone in working condition | Account is deleted, you can use without restrictions |
| Phone after reset (FRP-blocking) | The lock will remain, but you can log in under a new account. |

If your device is not displayed on Xiaomi, try logging in via another browser or clearing the cache. Sometimes changing the account region (for example, from Russia to Global) helps.
Method 3: Bypass FRP and delete Mi Account via Fastboot (for advanced)
If standard methods fail and the phone is locked after being reset, the only solution left is the Fastboot firmware, which requires a PC, a USB Type-C cable, and basic ADB/Fastboot knowledge. On the Redmi Note 9, it works stably, but there is a risk of βbrickingβ if errors occur.
What you need:
- π₯οΈ Windows computer 10/11 (Linux with fastboot and adb installed).
- π Original. USB-cable (poor cables may interrupt the connection).
- π Fastboot for Redmi Note 9 (download from official website).

Method 4: Delete Mi Accounts via EDL (Extreme Case)
EDL (Emergency Download Mode) is a firmware emergency mode that allows you to bypass most locks, including FRP and Mi Cloud Lock.
- π§ Unlocked bootloader (bootloader unlock).
- π» Special cable. EDL or short-circuiting.
- π Authorized Xiaomi Developer Account (for new devices).
On the Redmi Note 9, the EDL is logged in as follows:

- Press Volume up + Volume down and connect the cable to the PC.
- Hold the buttons for 10-15 seconds until the screen goes out (the phone will not appear in fastboot devices, but will be defined as Qualcomm HS-USB QDLoader 9008).
