Xiaomi мгновенное руководство по разблокировке загрузчика mtk

In this guide, we will show you the steps to unlock the bootloader on your MediaTek device using MTKClient. Out of the three popular chipsets- Qualcomm, MediaTek, and Exynos, it is the former one that has been the most ‘custom development friendly’ as we could get hold of its source code quite easily. With that said, we have also seen a massive improvement from MTK in recent years when it comes to this domain. The number of OEMs adopting this chipset has forever been on the rise.

Likewise, its performance in the custom binary segment is worthy of praise as well. Be it for flashing custom ROMs or installing a custom recovery, there’s a lot to look forward to. Moreover, you could also gain administrative access by rooting your device via magisk. But to carry out any of these tasks you will first have to checkmark an important prerequisite of the list- the bootloader on your MediaTek device needs to be unlocked. In this regard, the native method to carry out this task is by using the Fastboot Commands.

More often than not, it is either the fastboot OEM unlock or fastboot flashing unlock that will get the job done. In some instances, you might additionally need to execute the fastboot flashing unlock_criticial command as well. However, there are a few MediaTek devices that don’t accept any of these Fastboot Commands. if your device also falls in this domain, then this guide shall help you out. In this tutorial, we will show you the detailed steps to unlock the bootloader on your MediaTek device using MTKClient.

Make sure to take a complete device backup beforehand as the process will reset your device. Likewise, it could also nullify the device’s warranty.

2. Then launch the setup and proceed with the on-screen instructions to install it on your PC.
3. Also, when you launch the setup, make sure to checkmark Add Python to Path.
   
4. We would also recommend you take a note of its installation directory.
5. The default location is (replace username accordingly and XXX is the version number):

   C:\Users\username\AppData\Local\Programs\Python\PythonXXX

STEP 2: Install MediaTek USB Drivers

Next up download the USB Drivers for your MediaTek device. Then launch the setup and proceed with the on-screen instructions to install it.

STEP 3: Install UsbDk

STEP 4: Download MTKClient

Now download the MTKClient from GitHub and extract it inside Python’s installation directory.

STEP 5: Install Python Dependencies

1. Head over to the Python’s installation directory, type in CMD in its address bar, and hit Enter.
2. This will launch Command Prompt. Now execute the below command to install the client’s setup file

   python setup.py install

   

3. After that, execute the below command to install the required dependencies:

   python -m pip install -r requirements.txt

   

STEP 6: Boot Mediatek Device to BROM Mode

You will now have to boot your MediaTek device to BROM Mode. There isn’t any universal key combination or ADB Commands for the same. What you could do is power off the phone. Then press and hold either the Volume Up or Volume Down key, OR Volume Up+Volume Down+Power keys and then connect your device to PC via USB cable.

To check if the device has been booted to BROM Mode, execute the next command. If it accepts it, then your device has been successfully booted to BROM. If it shows any error, then try a different key combination until the code is accepted.

STEP 7: Unlock MediaTek Bootloader

1. Execute the following command to wipe your device [it will erase all data]:

   python mtk e metadata,userdata,md_udc

   

2. After that, again boot your device to the BROM Mode
3. Then execute the below command to unlock the bootloader:

   python mtk xflash seccfg unlock

   

4. If the above didn’t work out, then try out this one:

   python mtk da seccfg unlock

5. The bootloader on your Mediatek device is now unlocked and you may boot your device to the OS.

How to Relock the Bootloader on MediaTek

if for some reason, you wish to relock the bootloader on your MediaTek device, then first off, remove all the modifications from your device. In other words, flash the stock firmware if you are on a custom ROM or using a custom recovery like TWRP. Likewise, you will also need to unroot your device. For that, you could either use the Magisk App or simply flash the stock firmware.

Moreover, the process will also wipe off all the data from your device, so take a complete backup beforehand. Once all that has been done, boot your device to the BROM Mode (see STEP 6) and then execute either of the two commands to relock the bootloader (if you had earlier used the first command to unlock the bootloader in STEP 7, then use the first command below to relock it and so on).

python mtk xflash seccfg lock
python mtk da seccfg lock
