Lineage OS installation

Trying to install Lineage OS on MI A2 (jasmine_sprout) follow the instructions from:

https://wiki.lineageos.org/devices/jasmine_sprout/install

Unlocking the bootloader

  1. Enable OEM unlock - done
  2. fastboot oem unlock - done

Temporarily booting a custom recovery using fastboot

  1. Download a custom recovery - done
  2. Temporarily flash a recovery on your device.

The provided command fastboot flash boot <recovery_filename>.img did not work. I had run:

fastboot flash boot__a lineage-17.-20210123-recovery-jasmine_sprout.img

Installing LineageOS from recovery

  • With the device powered off, hold Volume Up + Power to reboot into recovery
  • The phone does not go into recovery mode

The current state of the phone

  • phone gets powered off by pressing power button for 10 seconds or so.

  • Turning the phone on will start the phone and show:

    • android-one logo on screen for 2 seconds
    • battery charging icon on the screen for a second
    • screen goes blank
  • Powering it on with USB plugged into laptop

    • android one logo foe two seconds
    • Shows the following messgae:
    The boot loader is unlocked and software integraty can not be guarranteed....

    PRESS POWER KEY TO PAUSE BOOT  
    
  • Same as above when Volume Up + Power buttons are pressed

  • Goes into fastboot when Volume Down + Power buttons are pressed

Recovery using TWRP

Started twrp using fastboot boot twrp-3.5.0_9-0-jasmine_sprout.img.

Click on reboot - on the resulting page, switch the boot slot. If its A, change it to B. Reboot into system

These two steps started the Android OS that came with the phone.
