LineageOS Updater crashing when trying to install update

The LineageOS Updater downloads updates fine, but crashes as soon as you hit Install.

Looks like there may be a bug that has something to do with an update that it already downloaded and installed, but waiting on the device to reboot.

Reboot the device to resolve the issue.

Other things to try would include deleting and redownloading the update and/or trying a different update.

  4. Push LineageOS zip via adb (or other methods)
  5. Install LineageOS zip

Other Notes

ADB and fastboot should be in the following directory.  May need to install them if they are not.

cd %userprofile%\appdata\local\Android\Sdk\platform-tools

Boot TWRP image using fastboot.  Run from the bootloader menu, should automatically load.

fastboot boot twrp.img

Seems like there can be some issues with the Pixel and it swapping A/B on boot.  You can use TWRP to reboot into A or B, or set it with fastboot

fastboot --set-active=b

Apparently a/b devices will show up as no os installed in TWRP

TWRP says no OS installed, system boot loops from LineageOS

Backup and restore

You can use adb to create a backup of your phone.  Not sure what all it backs up.  Once restored pictures, background, and other files seem to be there.

Backup with

adb backup -apk -shared -all -f \Path\to\folder\backup_name.ab

Restore backup with

adb restore \Path\to\folder\backup_name.ab
