How to unlock Xiaomi Redmi Note 9T: all the ways from the official anlock to bypass Mi-account

Xiaomi Redmi Note 9T is a popular smartphone with a powerful MediaTek Dimensity 800U processor, but sometimes users face the need to unlock it. This can be due to a forgotten password, buying a used device with a tied Mi-account account, wanting to install custom firmware or even locking hardware after a failed update. Unlike the models on the Qualcomm Snapdragon, the Redmi Note 9T has its own nuances due to the MediaTek chipset and Xiaomi’s security policy.

In this article, we will discuss all the current ways of unlocking – from the official bootloader anlock via the Mi Unlock Tool to bypassing the Mi-account lock (including methods for devices with MTK Bypass), you will also learn what risks alternative methods carry, how to avoid a “brick” (turning the phone into a “brick”) and what to do if the smartphone is locked after resetting. Importantly, the procedures for the Redmi Note 9T may differ from the instructions for other Xiaomi models due to the features of the hardware platform.

We warn you in advance: some methods require technical skills, and the wrong actions can lead to loss of warranty or irreversible breakdown. If you are not sure about yourself, contact the service center. For owners who bought a phone from hand, the section on bypassing the bindings to the previous Mi Account is especially relevant.

1.Preparation for Unlocking: What You Need to Know Before Starting

Before you start unlocking the Redmi Note 9T, make sure you understand the implications of each method. Official methods (for example, through the Mi Unlock Tool) are safe, but require waiting and following Xiaomi's rules. Informal methods (such as MTK Bypass or exploiting vulnerabilities) can:

• 🔓 Reset your phone to factory settings (loss of all data).
• ⚠️ Activate Anti-Rollback protection (if the firmware is older than the current one).
• 🛠️ Require soldering work (for example, for dumping) EDL-regime).

Also, consider that Xiaomi has tightened security policy: from 2022, it requires at least 7 days to connect the device to the account to unlock the bootloader (previously 72 hours). If you just bought a phone or dropped it, you will have to wait.

1. Turn off your smartphone.
2. Press Volume Down + Power before the Fastboot logo appears.
3. Connect your phone to your PC and type in the command: fastboot oem device-info
4. If the answer is Device unlocked: false, the bootloader is blocked.

Important: The Redmi Note 9T (model M2007J22G) uses a MediaTek Dimensity 800U chipset that does not support EDL mode via standard cables (unlike Snapdragon), which limits the recovery from the "brick." If you plan firmware experiments, pre-prepared an authorized MTK Auth Bypass cable or consult a specialist.

2. Official unlocking of the bootloader via Mi Unlock Tool

The safest way to unlock a bootloader on the Redmi Note 9T is to use Xiaomi’s official Mi Unlock Tool, which does not violate warranty (unless the phone has been unlocked before) and minimizes risks.

• ⏳ Requires a device-based Mi Account to be linked for at least 7 days (168 hours).
• 🌐 You need a stable Internet connection (the utility checks Xiaomi servers).
• 🔄 After unlocking all data on the phone will be erased.
• 🔑 Mi Account must be confirmed by mail and phone.

Step-by-step:

1. Link your Mi Account: In the same Developer Menu, find Mi Unlock Status. Click Add Account and Device. Confirm the link via SMS/mail.

Mi Unlock Tool

• Official page: en.miui.com/unlock.
• Use the latest version (at 2026 v6.5.224.24).
• Launch unlock: 1. Turn off the phone and press Volume Down + Power to log in to Fastboot. 2. Connect the phone to your PC (use the original cable!). 3. Launch Mi Unlock Tool on behalf of the administrator. 4. Sign in to the same Mi Account as the phone. 5. Press Unlock and wait until it is completed (usually 10-15 seconds). 6. Once rebooted, the phone will be unlocked, but the data will be deleted.

Method 2: MTK Bypass (for Dimensity 800U chipset)

This method works due to a vulnerability in the MediaTek protocol and requires special cable or soldering works:

• 🔌 Connect your phone to your PC in mode BROM (need MTK Auth Bypass cable or circuit of contacts on the board).
• 🖥️ Use utilities like this. SP Flash Tool or MTK Client for reset FRP (Factory Reset Protection).
• 🔄 After resetting, the phone will reboot without being tied to the account.
