How to enter flash mode

Bootloader Unlocking

Like other Xiaomi devices, the user will have to acquire the bootloader unlock key: https://en.miui.com/unlock

The device will not unlock if the device isn't 7 days old (from the time when your device connects to internet and powered on, and linked with Mi Account)

Recovery mode

Turn the device off (or restart also works)
Hold Volume Up and Power button
Once you feel vibration and phone turns on, release Power button
Keep holding Volume Up until you get to recovery.

Flashing (Download, Fastboot) mode

Same as recovery, but this time hold the Volume Down and Power keys.

Installation

Install pmbootstrap first on your PC
zap & reinit pmbootstrap (pmbootstrap -y zap ; pmbootstrap init), choose xiaomi-platina as a device
proceed with installation as usual: reboot device to fastboot mode, then:

pmbootstrap install
pmbootstrap flasher flash_kernel
pmbootstrap flasher flash_rootfs
pmbootstrap flasher flash_vbmeta

And then

fastboot reboot
