2. On the computer, open a terminal and type: adb reboot bootloader You can also boot into fastboot mode via a key combination:
   • With the device powered off, hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
3. Once the device is in fastboot mode, verify your PC finds it by typing: fastboot devices
4. Flash recovery onto your device: fastboot flash recovery twrp-3.5.0_9-0-davinci.img
5. Now reboot into recovery to verify the installation:
   • With the device powered off, hold Volume Up + Power. Keep holding both buttons until the “MI” logo appears on the screen, then release.

   • On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
   • On the host machine, sideload the package using: adb sideload filename.zip. Info: If the process succeeds the output will stop at 47% and report adb: failed to read command: Success.
5. (Optionally): If you want to install any additional add-ons, repeat the sideload steps above for those packages in sequence.
6. Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.
