How to completely delete an account from the phone Xiaomi Redmi Note 9: 5 proven ways

Deleting your Mi Account with Xiaomi Redmi Note 9 is a procedure you might need when selling your device, resetting to factory settings, or forgetting your login details. However, many users face problems: the system requires a password from your old account even after you reset, and standard deletion methods through settings don’t always work. In this article, we’ll look at all the current ways to delete an account, from official to technical (including ADB and Fastboot), and explain why the phone can remain tied to an account after a reset.

The Redmi Note 9 (M2003J15SC/M2003J15SS) features built-in Mi Cloud Lock protection that locks the device after deleting an account without the correct password, which means that simply resetting through Recovery is not enough: additional steps will be required. We tested all methods on MIUI 12-14 firmware (including global and Chinese versions) and identified those that work in 2026 without the need to contact a service center.

1. Delete the account through the phone settings (official method)

The easiest method is if you remember the Mi Account password and the phone is not locked, suitable for users who want to untie the device before selling or transferring.

Instructions:

• 📱 Open the Settings app (cog icon on the home screen).
• 👤 Go to the Accounts section → Mi Account.
• 🔄 Click on the three dots in the upper right corner and select Delete Account.
• 🔐 Enter the password from your Mi Account and confirm the action.

After that, the phone will be detached from the account, but the Mi Cloud data (contacts, notes, backups) will be deleted from the device. If you plan to sell the Redmi Note 9, perform a factory reset after deleting the account:

1. Go to Settings → About the phone → Reset settings.
2. Choose to erase all data and wait for the process to complete.

⚠️ Note: If you deleted your account but did not reset, the new owner will be able to recover your data via Mi Cloud (if backup was enabled!

2. factory reset via Recovery Mode (if the password is forgotten)

If you don’t remember the Mi Account data but the phone is unlocked, you can try resetting via Recovery Mode.This method doesn’t guarantee deletion of the account, but sometimes helps bypass lockdown after reset.

Step-by-step:

1. Turn off the Redmi Note 9 with a long press on the power button.
2. Press the Power button + Volume up at the same time and hold for 10-15 seconds until the Mi logo appears.
3. From the Recovery menu, select the language (if available) and go to Wipe Data → Wipe All Data.
4. Confirm the reset and wait for the reset.

After resetting, the phone can:

• 🔓 Start without requesting an account (unless previously activated Mi Cloud Lock protection).
• 🔒 Require data entry from your old account (if your device is tied to the Mi Cloud).

⚠️ Note: On models Redmi Note 9 with firmware MIUI 13+ Recovery resets often do not remove the account’s attachment, in which case alternative methods will be required (see Sections 3-5).

Turn off the phone.

Press the power button + volume up

Wait for the Recovery menu to arrive

Choose Wipe Data → Wipe All Data

Confirm reset and restart the device-->

3. Delete account via ADB (for experienced users)

The Android Debug Bridge (ADB) method is suitable if the phone is turned on but blocked by an account request after a reset, and you will need a computer with Xiaomi drivers installed and USB debugging enabled.

Instructions:

1. Download and install ADB Tools on PC.
2. Connect the Redmi Note 9 to your computer via USB-cable.
3. Open the command prompt (cmd) in the folder with ADB and type:

adb shell


pm uninstall -k --user 0 com.xiaomi.account

If the team doesn’t work, try an alternative:

adb shell am start -n com.android.settings/.MiAccountSettings


adb shell input text "your password" # (if you know the password)




adb shell input keyevent 66

This method does not always work on newer versions of MIUI, as Xiaomi has tightened the protection. If the commands return the Permission denied error, go to the method from Fastboot (section 4).

4 Unlock via Fastboot (if the phone is locked)

If Redmi Note 9 requires a Mi Account after reset and does not respond to other methods, you can try to remove the binding via Fastboot.This method requires an unlocked bootloader and can lead to a loss of warranty.

Step-by-step:

1. Turn off the phone and put it in Fastboot mode: press the Power button + Volume down.
2. Connect the device to your PC and open the command line in the folder with ADB.
3. Enter a command to check the connection:

fastboot devices

If the device is determined, perform:

fastboot oem clean_all


fastboot reboot

This command completely clears the partition with the account data, but does not work on all firmware. If the account request remains after the reboot, try flashing the phone through the Mi Flash Tool (section 5).

⚠️ Attention: Team fastboot oem clean_all This can cause a device to break if the bootloader is locked. Before using it, check the bootloader status with the fastboot oem device-info command.

5. Phone firmware via Mi Flash Tool (last resort)

If all previous methods fail, you can completely flash your phone through the official Mi Flash Tool, which deletes all data, including your account, but requires:

• 💻 Windows computer;
• 🔌 Original. USB-cable;
• 📥 Redmi Note 9 firmware (version should match the region of the phone).

Instructions:

1. Download the firmware for your model (M2003J15SC or M2003J15SS).
2. Unpack the archive and install the Mi Flash Tool.
3. Transfer the phone to Fastboot mode (power button + volume down).
4. Connect the device to your PC, open the Mi Flash Tool and select the firmware folder.
5. Press Refresh, then Flash and wait for completion (10-15 minutes).

Once the firmware is in place, the phone will start as new, without being tied to the account, but the warranty can be cancelled if the device has been blocked by the manufacturer.

💡

Before you run the firmware, check the phone's IMEI (type *#06#).If the IMEI drops after the procedure, restore it through the engineering menu or contact the service.

6. Calling for Xiaomi support (if nothing helps)

If all methods are useless, the official path remains to appeal to Xiaomi, which is true if:

• 🔒 Phone locked after reset and requires an old account;
• 📄 You have proof of purchase (check, box with) IMEI);
• ⏳ You will be ready to wait for a response up to 7-14 days.

How to apply:

1. Go to the Xiaomi support website.
2. Select Unlock Device or Account Issues.
3. Fill out the form by specifying the IMEI of the phone (you can find it on the box or via *#06#).
4. Attach scans of the check or warranty card.

The support service may:

• 📧 Send a link to unlock;
• 🔑 Provide a temporary access code;
• 🚫 Refuse if the device is listed as stolen.

⚠️ Note: Xiaomi will not unlock devices purchased with undocumented hands.If you purchased the Redmi Note 9 in the secondary market, ask the seller for help in unblocking the account.

💡

Firmware via the Mi Flash Tool is the only reliable way to delete an account if the phone is locked after a reset, but it is an extreme measure that can take away warranty.
