Before we step in further, there is one thing that you should understand.
Flashing third-party binaries on your phone is basically a safe process if done right. However, things might go wrong.
Hence, we strongly suggest you to create backups of your important data and files. Flashing a custom recovery replaces the stock one. On top of that, the process demands an unlocked bootloader. The process of unlocking bootloader of recent Xiaomi phones will wipe your data and do a factory reset.
We hold no responsibility of any damage that may happen to your device. No body forces you to do what we guide you in this article. Please proceed with caution.

Step 7. Copy that recovery.img file and misc.bin file into the “platform-tools” folder (Step 3).

Step 12. Now type following lines of command. Hit Enter every each line to issue it.
adb reboot bootloader
The first line asks your computer to recognize your device. The second line instructs your phone to boot into bootloader mode a.k.a fastboot mode. You’ll see the Mi Bunny logo displayed.
This instructs your computer to establish ADB connection with your device while verifying any device attached. Second, this also reboots your device into Fastboot mode (bootloader mode). You will see your phone rebooting and you will also see the Mi Bunny Fastboot logo displayed.
Step 13. Next, type following command lines and hit Enter on keyboard:
fastboot flash recovery recovery.img
fastboot flash misc misc.bin

How to Boot Into TWRP Recovery
There are mainly two methods you can choose to boot your Redmi K20 Pro to recovery mode which in this case is TWRP. The first method is useful if your phone is still connected to computer and USB Debugging is enabled. The second one is handy especially if your phone is not connected to a computer.
Boot into TWRP via command line
Use this method if the phone is still connected to the computer. For instance, you’ve just followed steps above and you want to boot into TWRP for the very first time.
Type the command below and hit Enter:
adb reboot recovery
Boot into TWRP using button combination
Let’s assume you have unplugged the phone from the computer. You can use this method which is easier and is applicable anytime without any computer around.
First, turn off your phone completely. While the phone is off, press the Power button and the Volume Up button simultaneously. Hold it around 3-5 seconds until the phone reboots into TWRP recovery.
Next, you have to do the “Swipe to confirm system modification” if this your first time entering TWRP. Once swiped, you’l be in the main menu of TWRP.
LR.Team’s TWRP is in Chinese by default. You have to follow our previous guide on how to change its language to English.
How to Root Redmi K20 Pro (Optional)
Step 1 – Download Magisk zip file to your phone. Alternatively, you can also download it to your computer and transfer it to your phone.
Step 2. Boot into TWRP recovery using one of above methods.
Step 3. Choose “Install” from the main menu.
Step 4. Now locate the Magisk zip file in your phone’s internal storage. Usually, the zip is in Downloads folder if you download it to your phone directly.
Step 5. Tap on its file name to select it.
Step 6. Next, do the “Swipe to confirm flash” action.
Step 7. The TWRP will do its magic and it’ll flash Magisk to your phone.
Step 8. Finally, choose “Reboot” then choose “System“.
Voila! Your Redmi K20 Pro phone is now rooted!
Being a new phone doesn’t mean it will be left with no option. Redmi K20 Pro receives its first TWRP recovery thanks to Wzsx150‘s work. The build is in Chinese unfortunately.
Still, it also has English language and can be switched into easily.
We are still waiting for its official global release and let’s hope the official TWRP build will also come soon after its global release.
Meanwhile, using LR.Team TWRP above is the best option to enjoy flashing custom ROMs or to root the device.
