Notes

This device is quite similar to the Xiaomi Redmi Note 7 (xiaomi-lavender) and Xiaomi Redmi Note 8T (xiaomi-willow), and many of the issues were solved with steps from that devices pages, so if you're hacking on the Mi A2 it's a good idea to read the xiaomi-lavender and the xiaomi-willow page closely.

LED / Torch / Screen brightness / Vibrator

Write brightness or boolean value to specific sysfs files:

  • Front panel LED light [0-255]: /sys/class/leds/white/{brightness,blink}
  • Torch light [0-255]: /sys/class/leds/flashlight/brightness (torch_0 is cold light, torch_1 is warm light)
  • Screen brightness [0-255]: /sys/class/leds/lcd-backlight/brightness
  • Vibrator [Miliseconds]: /sys/class/timed_output/vibrator/enable

Example: echo 255 > /sys/class/leds/lcd-backlight/brightness That maximizes the brightness of the screen

How to enter flash mode

Bootloader Unlocking

Unlocking the bootloader will erase all your data, so make sure you have backed up all your data before proceeding with unlocking the bootloader.

Because this device is an Android One device, it can be unlocked using fastboot oem unlock and then fastboot flashing unlock_critical from fastboot mode.

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
  • pmbootstrap -y zap; pmbootstrap init, choose xiaomi-jasmine_sprout as your device
    • GNOME have been successfully tested.
  • pmbootstrap install
  • Enter fastboot, plug USB into computer
  • pmbootstrap flasher flash_kernel
  • pmbootstrap flasher flash_rootfs
  • pmbootstrap flasher flash_vbmeta
  • Reboot, sometimes fastboot reboot works, otherwise hold down Power until it reboots.


  • In addition to the GUI, you can also connect via SSH ssh user@172.16.42.1
