Unlock

You must use a Windows 10 computer.

On phone

Before you start, write down some information about your phone.

Go to Settings -> About phone -> All specs.

Write down:

• MIUI version = especially between ()
• Model = M1906G7*
• Baseband version

Or just take a picture ;-)

1. Go to Settings -> About phone -> click 7 times on -> MIUI version until Developer options are available.
2. Go back to Settings -> Additional settings -> Developer options -> enable OEM unlocking -> click on Mi Unlock status and Add account and device -> copy id number under your avatar
   (Create a new account if necessary.)

On computer

1. Go to miui.com and click on unlock. Change language to english (footer). After logging in, you must create a new user for the forum if you have just created an account.
   

   TIP 1: Use some chinese signs behind your nickname if you're using the alphabet.
   
   
   TIP 2: Follow again `step 1` to reach the site -> [download - unlock file]

2. Connect your phone and let Windows install all necessary drivers.

3. Now turn your phone off and start it again with VOL DOWN + POWER BUTTON and hold it until FASTBOOT is written. Connect your phone and let Windows install all the fastboot drivers for your phone (if not done in step 1).

4. Download Mi Unlock and extract the files to C:\unlock\ and start miflash_unlock. Sign in and connect your phone again if necessary. Now click unlock button.

   Problems (Unlock button greyd out)? Try that XDA.
   Couldn't unlock - Please unlock XXX hours later? Wait XXX hours later.

5. Click on Unlock -> Unlock anyway -> Unlock anyway

Up to this point it is no longer necessary to use a Windows computer.

USB debugging

1. Go to Settings -> About phone -> click 7 times on -> MIUI version until Developer options are available.

2. Go back to Settings -> Additional settings -> Developer options -> enable USB debugging.

Brick safe mode

This is a quick guide with the important info. Check the xda thread for the whole info!

Before you go any further make sure you're running Android 9!!! If you are on Android 10, you must first downgrade.

1. Go to Settings -> About phone.

fastboot

Download full factory build and extract the file. Or just the 2 files from xda.

Reboot your phone to fastboot mode by holding VOL DOWN + POWER BUTTON or run adb reboot bootloader in your terminal.

Got to the images folder and run the following commands:

fastboot flash preloader preloader_begonia.bin
fastboot flash lk lk.img
fastboot flash lk2 lk.img

TWRP

Download

Download Firmware

You have 2 options to download your firmware:

1. mi.com
2. Your phone

I suggest the number 2. That way it's pretty sure you'll be using your firmware for your particular phone.

For that, got to:

1. Go to Settings -> About phone -> System update -> 3 dots (top right)) -> Download latest package
2. Connect your phone to your computer click on File transfer and go to the folder downloaded_rom and copy the file to your computer.

Android Verified Boot (AVB)

This device uses Android Verified Boot (AVB)
This means that installing TWRP or swiping to allow system modifications will prevent you from being able to boot. To bypass AVB's boot prevention, you will have to disable it or install a custom ROM that ships with disabled AVB.

To disable AVB via fastboot, grab the vbmeta image from the ROM you are on, and flash it with the following command:

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

AVB should be now disabled on your device.

Click on your downloaded firmware and extract vbmeta.img.
Reboot your phone to fastboot mode by holding VOL DOWN + POWER BUTTON or run adb reboot bootloader in your terminal.

Copy both files vbmeta.img and twrp-3.3.1-0-begonia.img in one folder and run the following commands:

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot flash recovery twrp-3.3.1-0-begonia.img

Restart your phone with fastboot reboot and immediately press and hold VOL UP until you reach the recovery mode or until you need to select the recovery mode.

OTA updates

For Brick safe mode

You need to check whether the MIUI OTA you're installing contains Preloader and LK or not. If it does, remove it manually. Another method could be to install the OTA and then flash the factory Preloader and LK image again via fastboot.

For TWRP

1. Download firmware
2. Delete the compability.zip archive
   

1. Go into the META-INF directory and locate updater-script
   

1. Delete lines such as:
   

   assert(set_emmc_writable("/sys/block/mmcblk0boot1/force_ro"),
          package_extract_file("preloader.img", "/dev/block/mmcblk0boot1"));

   and

   assert(set_emmc_writable("/sys/block/mmcblk0boot0/force_ro"),
          package_extract_file("preloader.img", "/dev/block/mmcblk0boot0"));

2. Save the changes and now flash the build.

3. Do TWRP again.

Custom ROMs

Looking forward ;)
