What is LineageOS?

Installing LineageOS on Xiaomi Mi A1

Use the following commands to unlock the bootloader. Run them from the adb and fastboot folder:

adb devices

adb devices
adb reboot bootloader
fastboot oem device-info

Recovery Mode Installation

After enabling USB debugging mode and unlocking the OEM, install recovery mode using the .img file in the same folder as adb and fastboot:

1

fastboot flash recovery twrp-installer-3.3.1-0-tissot.img

The following error occurs:

Image Installation

Reboot into recovery mode with power button + volume up and follow these steps:

  1. Wipe -> Format Data
  2. Advanced Wipe -> Dalvik, system and data
  3. Install -> lineage-1-…-tissot.zip
  4. Wipe Dalvik and reboot system.

Once completed, LineageOS is installed. By default, Google Play is not included. If you encounter any errors, you can install the minimal version of GApps, for example open_gapps-arm-9.0-pico-20200408.zip.
