We hope this quick & easy tutorial will be useful and it will help you to avoid the bootloop & fastboot loading issues. Don’t forget to make all required backups on your phone before doing any actions!

Install TWRP Custom Recovery & Root POCO F2 Pro / Redmi K30 Pro

First of all and most important step here is to enable text password lock on your phone and enable USB debugging.

1. Download the misc.bin file & TWRP 3.4.2b version for Poco F2 Pro and move both files to same folder with platform-tools.
   1. Rename downloaded TWRP .img file to just twrp.img to make things easier in the next steps.
2. Start your smartphone in fastboot mode and open command prompt on your Windows OS PC.
3. Now enter the following commands in the same order:
   1. fastboot devices (to check if your device is successfully connected to your PC).
   2. fastboot flash recovery twrp.img
   3. fastboot flash misc misc.bin
   4. fastboot boot twrp.img
4. Your phone should now reboot into TWRP and will request the text lock password, enter the password that you’ve setup previously and now /data partition should be decrypted and we can continue using the TWRP Custom Recovery.
5. Go to Reboot > System and proceed with reboot to the system.
6. It could be that TWRP will be removed on the first boot into the system. In this case, you just need to flash it again, but this time don’t use the following command: “fastboot boot twrp.img” and manually reboot into TWRP by pressing Volume Up + Power buttons at the same time.
7. Now, the final step is installing the Magisk.
8. Copy the Magisk.zip file into the phone internal memory, boot into TWRP and flash Magisk.
9. After installation reboot into system.
10. You’ve Magisk installed and working.

Magisk Root for Redmi 9 Android Device

We’ll keep this guide short, so I believe you already know how to use Fastboot & ADB tools. If the answer is yes, you can continue, otherwise get some knowledge in the web. Next you’ll need to make sure that you have unlocked device. This requires you to make an request, wait for an answer (usually takes around a week or so), then you’ll need to wipe your device and finally, it’s unlocked!

1. Let’s boot in the fastboot mode (turn off your device and then use “Power” button and “Volume Down” at the same time).
2. Install required drivers and ADB / fastboot tools (you can find download links in the first part of the article).
   • How to use ADB / fastboot?
     • ADB / fastboot is basically a console utility, so we’ll need to use them from the command line.
     • Download and unpack the archive, open the folder with unpacked files, tap on the address bar, where’s the path of the folder, type (without quotes) and press Enter.
     • Terminal window will open. Now proceed using the ADB tools with required commands.
3. Download and put vbmeta & magisk_patched.img files into the same folder with ADB.
4. First we’ll patch the vbmeta file.
   • vbmeta – Is a special partition which contains digital signatures to prevent the bootloader from running any third-party app and is responsible for different integrity checks.
5. Connect your device in fastboot mode and check if it’s identified with the following command: “Fastboot devices” in terminal window.
6. Next enter the following command:
   • fastboot –disable-verity –disable-verification flash vbmeta vbmeta.img
7. Then use the Magisk patched boot.img file:
   1. fastboot flash boot magisk_patched.img
8. Reboot your device in the normal state, download & install Magisk tool.
9. You should now have root enabled on your device.

Flashing TWRP Custom Recovery Tutorial for Mi 6X (wayne)

Let’s begin:

1. Download the following archive: TWRP_Xiaomi_Mi_6X_wayne.zip
2. Extract downloaded archive. Then go to “Root” folder, select the suitable root method and move one archive (supersu.zip or magisk.zip) to phone internal memory.

7. Press “Reboot system”, after that your phone will reboot and start with enabled root access.

Additional notes:

If TWRP Custom Recovery asks you to enter the password – that means that you have encrypted Data partition on your device. The only solution is formatting. Click “Cancel” > select “Wipe” and click “Format data” button, then type “Yes” to confirm. Pay attention, that if you’re going to format “Data” partition, all phone internal memory and your personal files are going to be deleted, so make sure you’ve all required backups.

1. First, download the ROM (custom firmware) you want to flash. Make sure you choose one that is for your specific Mi device (in your case for Mi Mix 2). Here are some of the most popular ROMS.
   1. Lineage OS – download here.
      Note: In case you lose the root access, and you want to keep it after installing Lineage OS, download the addonus-15.1-arm64-signed.zip file from the following link. After you install the ROM flash addonus-15.1-arm64-signed.zip using TWRP, and you will get the root access.
   2. AICP – download here.
   3. OMNI – download here.
      Note: In case you lose the root access, and you want to keep it after installing AICP or OMNI ROMs, flash the Magisk file again using TWRP (as you did in the Rooting section from above).
2. Now, download Google Apps.
   Select the right Platform and Android version of your ROM as well as the variant you want to use. Then click the download button, and store the downloaded file into your phone memory.
3. Enter Recovery Mode (check the step 5 from the previous section if you do not know how to do that).
4. While in the TWRP interface, wipe the following: Dalvin / Art Cache, Data, Cache. (DO NOT wipe Internal Storage).
5. Now, go back to the main TWRP screen and flash the ROM you previously downloaded.
6. Once the installation finishes, flash the Google Apps file you downloaded before.
7. If you want to keep the root access, flash addonus-15.1-arm64-signed.zip (in case you installed Lineage OS) or the Magisk file (in case you installed another ROM).
8. Reboot your Mi device and enjoy your new custom ROM.
