The procedure to unlock the bootloader on Xiaomi devices, and in particular on the popular Redmi Note 8 T model, is a fundamental step for those who want to gain full control of their gadget. The standard MIUI shell, although functional, often limits the capabilities of advanced users, hiding access to system files and blocking the installation of modified software. It is unlocking the bootloader that opens the door to install custom recaps, gain superuser rights and replace the stock firmware with lighter and faster versions of Android.
Many smartphone owners are afraid to start this procedure because of the risk of turning the device into a “brick”, but with strict follow-up to the instructions, the process is successful in the vast majority of cases. It is important to understand that this operation will completely clean up the internal memory of your Xiaomi Redmi Note 8 T, so pre-backup of all important data is a prerequisite. In this article, we will discuss every step from preparing the Mi Account to the final command entry in Fastboot mode.
Before we get started, Xiaomi has implemented several layers of protection to protect users from accidental data loss or device theft, and linking to an account and having to wait for days is not a bug, but a feature of the manufacturer’s security policy, and ignoring these requirements will only lead to a waste of time and inability to complete the procedure.
⚠️ Warning: Unlocking the bootloader will automatically void the device warranty in most official service centers. This also makes it impossible to use certain banking applications and services with a high degree of protection (for example, Google Pay can stop working without additional manipulation).
Preparation of the device and necessary tools
The success of the operation depends on the quality of preparation. You will need not only the Redmi Note 8 T smartphone itself, but also a working computer running Windows, as well as a high-quality computer. USB-A cable that can transmit data, not just charge the battery, and using damaged or too cheap cables is one of the most common causes of communication to a device at a critical moment.
The first step is to activate hidden features in the system. To do this, go to the settings, select About Phone and quickly click 7 times on MIUI Version until you notice that you have become a developer, and then a new option will appear in the “Additional” menu, where you need to activate Debugging over USB and the “Factory Unlock” function.
Next, download and install the official Mi Unlock Tool on your computer, which is the only legal way to unblock Xiaomi servers, and make sure that your PC has the current ADB and Fastboot drivers, which are usually offered for installation with the unlock tool or through the SDK Platform Tools.
- 📱 Charge the Redmi Note 8 T to at least 60% to avoid a sudden shutdown in the process.
- 💻 Install the drivers. ADB/Fastboot Mi Unlock on a Windows computer.
- 🔒 Tie it up. SIM-A mobile internet card to the Mi Account that will be used to log in.
- 📂 Make a full backup of all contacts, photos and apps as the memory will be completely cleared.
☑️ Checklist before kick-off
Registration and binding of the Mi Account
The most important step that most newcomers stumble upon is to properly link an account. Xiaomi’s security system requires that the account used to unlock be “trusted” for a particular device, and click on the Add Account and Device button on the Factory Unlock menu.
Please note that at this point in the smartphone should be installed SIM-card, and mobile Internet should be active for data transfer, Wi-Fi should be temporarily disabled to avoid priority conflicts. Once successfully linked, you will see a message that the account has been added, but this does not mean permission to unlock.
The standard waiting time is 168 hours (7 days), although in rare cases the server can give permission after 36 or 12 hours. Re-associating the account during this period will reset the timer, so be patient and do not try to speed up the process artificially.
💡
If the timer shows that you have less than 24 hours to wait, do not try to unlock the device ahead of time - the server will reject the request and you will have to wait again.
Application process and waiting
Once you've tied the device, the countdown begins, during which time it's recommended to actively use your smartphone as normal, make calls and surf the Internet from mobile traffic, which helps Xiaomi servers confirm that the device is being used by a real person, not a bot.
You can check status in the Factory Unlock app or in the Mi Unlock program on your PC by connecting your phone. Status will vary from "Wait" to "Unlock is allowed." If after 7 days the status has not changed, try rebooting your smartphone and reconnecting it to your PC.
There is a myth that you can reduce latency by changing the region or version of MIUI. In practice, this rarely works and can lead to anchor errors. The best strategy is to simply wait for the system to get the server permission.
| Status at Mi Unlock | Meaning | User actions |
|---|---|---|
| Connecting... | Searching device | Check the cable, drivers, clamp Vol- + Power |
| Locked | bootloader locked | Normal condition before unlocking |
| Waiting (168h) | Waiting for permission | Do nothing, wait until the time is up. |
| Unlocked | Unlocked. | You can install custom Recovery |
Direct Unlocking via Fastboot
When the timer has expired and the status has changed to "Unlock permitted," you can proceed to the final stage. Turn off the smartphone completely. Then press the volume down and power button at the same time. Hold them until the image of a hare repairing an android appears on the screen or the inscription FASTBOOT.
Connect your phone to your computer and launch the Mi Unlock Tool. Log in to the same Mi Account you previously linked to, the program will automatically detect the device and check the status on the server, and if all the conditions are met, the Unlock button will appear.
Press the button and confirm the action in the pop-up window. The process will take a few seconds, after which the phone will automatically restart, at which point there will be a complete reset (Wipe Data), which is the normal behavior of the security system.

⚠️ Warning: During the unlocking process, the phone screen may go out or freeze on the logo.Do not panic or turn off the cable until the program on the computer reports a successful completion or obvious error.
Installation of custom TWRP Recovery
Once the bootloader is successfully unlocked, the standard recovery menu becomes useless for deep modifications. TWRP (Team Win Recovery Project – the gold standard custom recovery, allowing you to make full backups, install ZIP-archives and obtain Root rights.
For the Redmi Note 8 T (codename ginkgo or willow) must be downloaded from the specific version. TWRP, Because the firmware from another model may cause the touchscreen or fingerprint sensor to fail, the installation process is done via the command line using the fastboot flash recovery command. twrp.img.
An important nuance for Xiaomi owners: after the first installation of TWRP, you can not immediately boot into the Android system, otherwise the stock recavery will overwrite the custom one. You must immediately boot into Recovery mode (clamping Power + Vol+), where TWRP will offer to install a patch to save or simply confirm access to the system.
What if TWRP doesn’t see internal memory?
Getting Root Rights and Installing Magisk
One of the main purposes of unlocking is often to gain superuser rights, and the current standard is the de facto Magisk manager, which allows you to get Root access in a system-safe way, hiding it from banking applications.
For installation download the current ZIP-Magisk archive and transfer it to your phone. TWRP, You can select Install, find the archive, and then you can run it, and then you can reboot the Magisk app, which confirms that you have rights.
The presence of an unlocked bootloader and Root-rights gives unlimited possibilities: removing system debris, changing the processor frequency, installing modules that change the interface and functionality of the system, as well as completely replacing the operaonic system with custom Android assemblies.
- 🚀 Full control of the file system and system processes.
- 🎨 Ability to deep customization of the interface and animations.
- 🛡️ Installation of system ad blockers and firewalls.
- 💾 Creating complete system images for quick recovery.
Possible problems and ways to solve them
Despite the fact that the procedure is well-established, sometimes errors occur. FAILED (remote: device is locked) means that you are trying to flash a device with a locked bootloader or using the wrong account. FAILED (status 7) code when you are running through TWRP indicates a mismatch between the firmware version and the backup version.
If the phone goes into an endless bootloop after unlocking, most likely the system files are allowed during cleaning, in which case only flashing the stock ROM through the Mi Flash Tool program in Clean All mode will help.
Users also often experience a “Device is locked” problem when downloading if the Data formatting procedure has not been performed after the first unlock.
💡
The most common mistake is trying to unlock your device with an account other than the one that was tied to the phone menu 7 days before.
