How to enter flash mode

  • Fastboot: Power on the device with both Power and Volume Down buttons.
  • lk2nd Fastboot: Power on the device. After it vibrates, hold Volume Down.
  • lk2nd Recovery: Power on the device. After it vibrates, hold Volume Up.

Installation

  1. Make sure you have latest firmware flashed. Follow the LineageOS installation guide until (including) Updating firmware.
  2. Install lk2nd. Although Xiaomi already provides a Fastboot interface, lk2nd contains various quirks for booting mainline.
  3. Follow Qualcomm_Snapdragon_410/412_(MSM8916)#Installation. (Flash from lk2nd Fastboot, not the stock Fastboot.)
