A forgotten password on the Xiaomi Redmi 9T can become a real headache, especially if the smartphone stores important data. Unlike Apple devices, where unlocking without a password often requires contacting the service center, Redmi owners have several working ways to return access themselves.
In this article, we will discuss all the current ways of unlocking in detail, from official (via Mi Account) to technical (via Fastboot and EDL). Particular attention will be paid to the unique feature of the Redmi 9T: models with a Snapdragon 460 processor do not support unlocking through Mi Flash in EDL mode without authorization, which narrows the list of working methods.
1 Unlocking through Mi Account (official method)
The safest method that doesn’t require a data reset is to use a Xiaomi account that works if:
- 🔹 Smartphone connected to the Internet (Wi-Fi or mobile network)
- 🔹 You remember the username and password from Mi Account that was tied to the device.
- 🔹 The “Find the device” function was not disabled on the phone"
Instructions:
- On the lock screen, click Forgot your password? (bottom of the screen).
- Choose Unblock with Mi Account.
- Enter your email/phone and account password. If two-factor authentication is enabled, confirm your login via SMS or email.
- Follow the system instructions to create a new lock password.
⚠️ Note: If you have previously changed your Mi Account password but have not updated it on your smartphone, the system may request the old account password, in which case, try to restore access to your account through account.xiaomi.com.
2. Hard Reset via Recovery Mode (reset to factory settings)
If Mi Account is lost, the radical method is a complete reset, which removes all data from the device, including photos, contacts and apps. On Redmi 9T, the reset is done via the Recovery menu, but there are important nuances:
Turn off your smartphone (clip Power + Volume up for 10 seconds)
Connect the charger (the battery must be charged at least 30%)
Prepare. SIM-card or flash drive with firmware (in case of errors)
Remember your Mi Account (required after reset)

If the phone asks for an old password after reset, try connecting to Wi-Fi and entering Mi Account details via a browser on another device - sometimes this removes the lock.
3. Unlock via Fastboot (for advanced users)
The method via Fastboot is suitable if:

- Reboot your phone with the command: fastboot reboot
| Team team. | Description | Risks. |
|---|---|---|
| fastboot oem clean_all | Full reset to factory settings | Delete all data, may require FRP-circumvention |
| fastboot erase userdata | Deletes user data | It can lead to a hang on the logo. |
| fastboot erase frp | Reset Factory Reset Protection | It doesn’t work on all versions of MIUI. |
⚠️ Note: Some of the Redmi firmware 9T fastboot commands can be blocked. If an error occurs after entering the command FAILED (remote: 'Command not allowed', try unlocking the bootloader first via the Mi Unlock Tool (requires Mi Account binding and waits 72–168 hours).

Ways of circumvention:
- 📱 Using emergency call: On the lock screen, press Emergency call. dial ##4636## (may not work on new firmware). If the test menu opens, go to Settings and turn off FRP.

EDL (Emergency Download Mode) is a "emergency" firmware mode that allows you to reflash your phone even when you lock it completely. However, on the Redmi 9T with a Snapdragon 460 processor, this method has limitations:
- ⚠️ You need an authorized Xiaomi account to use the Mi Flash Tool.
