Start charging your device and carefully read the manual a few times until you’ll understand each part, by doing this you’ll reduce the chances of getting hard / soft bricked device in the end.

First all of all, you must have unbricked device. Next step is to install any available TWRP Recovery version:

• TWRP Recovery by FeLLzMODs
• TWRP 3.3.1-32 by mauronofrio at XDA
• PitchBlackRecoveryProject

To boot into recovery turn off your device, then press and hold volume up and press the power button. After the display lights up, release the power button and keep holding volume up button until your phone boots into Recovery mode.

How to install Custom ROM on K20 Pro / Mi 9T Pro (Raphael)?

If you already have the Custom ROM installed and you want to update / re-install the same Custom ROM version, boot into Recovery, do Wipe “Cache” & “Dalvik”, re-install Magisk for root and if you’re using f2fs filesystem, then you’ll need to install the following patch (will work if you encrypted data partition):

• TWRP-3.3.1-1101-REDMI_K20PRO-CN-wzsx150.zip
• fstab_patch_F2FS_Cache_NoBarrier_NoEncryption.zip

If you already have Custom ROM installed, but want to flash a different one, then follow these steps:

1. Boot into Recovery mode.
2. Wipe > “Data”, “Cache”, “Dalvik”.
3. Download and install the corresponding to your region firmware.
4. Install Custom ROM.
5. Flash Gapps (in case they’re missing in the ROM you’ve chosen).
6. Flash Magisk (optionally).
7. Also you can flash DFE if you want to.
   • Disable_Dm-Verity_ForceEncrypt_01.19.2020.zip
8. Reboot.
9. Enjoy newly installed firmware.

In case your device doesn’t load or bootloop, you can try the following solution. Boot into recovery and format the “Data” partition (not to be confused with “wipe”!). Pay attention that this will delete all personal data on your device, so make sure to do a backup with your PC before doing this if you care about the data.

If you have official MIUI ROM installed and you want to switch to Custom firmware, then here’s the instructions on how to achieve that:

Keep in mind, that you firstly need to unlock the Bootloader on your device before proceeding. Pay attention that all data will be removed during the installation process, so make sure you do all the required backups (you can use Migrate or Titanium backup apps). Save the backup in a safe place.

1. Turn off your device and then boot into Recovery.
2. Go to “Wipe” in the menu and wipe “Cache”, “Dalvik”, “Data” and “System”.
3. Download and install the corresponding to your region firmware.
4. Install Custom ROM.
5. Flash Gapps (in case they’re missing in the ROM you’ve chosen).
6. Flash Magisk (optionally).
7. Also you can flash DFE if you want to.
   1. Disable_Dm-Verity_ForceEncrypt_01.19.2020.zip
8. Reboot.
9. Enjoy newly installed firmware.

If your device seems to be bricked or went in to the bootloop, try the solution described above. It helps in pretty much every possible case.
