Flash with ADB

Download the ROM file from the link in the post

Download Lineage OS recovery images for your device from the link below or extract from the ROM with payload dumper. Sometimes I may include them, check the post for recovery images.

https://download.lineageos.org/devices/bramble/builds

Flash the recovery images:

fastboot flash boot boot.img

fastboot flash dtbo dtbo.img

fastboot flash vendor_boot vendor_boot.img

Now reboot to recovery ( use buttons )

adb sideload project_matrixx.zip

wipe/format data

Reboot system

Notes:

• project_matrixx.zip is not literal. Don't type it out.

• You can drag and drop the rom.zip and .img file after typing the command.

fastboot flash boot <drag and drop boot.img>

• You do not need to format data when updating, unless otherwise specified.
