Howto Upgrade LineageOS From 17.1 to 18.1

Recently a major update landed in LineageOS updater for my phone (Oneplus 6 - codename enchilada). Originally I put there Android 10 - LineageOS 17.1 and the newest is Android 11 - LineageOS 18.1.

As major updates cannot be automatically installed, I went to follow the upgrade guide and do it manually.

The update went smoothly and there were no problems.

Basically I followed the upgrade guide and searched for some additional stuff.

  • recovery update is not needed
  • update to latest LineageOS 17.1
  • install android-tools to have adb utility
  • enable developer mode by tapping 7 times on phone info in settings and enable USB debugging and ADB only
  • connect phone to the computer and select as connection type USB debugging and confirm the fingerprint
  • now you should see your device in adb devices - might need to run as root
  • download lineage from https://download.lineageos.org/enchilada
  • download Google Apps if you want - MindTheGapps - I need them, because some application won’t work without them unfortunately (vendor lock-in ftw)
  • run adb reboot sideload and wait until it boots into recovery
  • upload new lineage with adb sideload ~/Downloads/lineage-18.1-20210504-nightly-enchilada-signed.zip and wait until it uploads and installs
  • then click Advanced and Reboot to Recovery and after reboot Apply Update and Apply from ADB and then adb sideload ~/Downloads/MindTheGapps-11.0.0-arm64-20210412_124247.zip and wait until it uploads and installs
  • reboot
  • and it’s done!
