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

$ pmbootstrap init # choose Vendor: qcom Device codename: msm89x7
$ fastboot flash dtbo dtbo-xiaomi-olive.img # Build from barni2000/dtbo-lk2nd repo
$ fastboot flash boot lk2nd-msm8952.img # Build lk2nd from msm8916-mainline/lk2nd repo
