Use partitions backup and restore from playstore. Go into settings of app first and change to save as raw image. Saves to SD card.Really wanna try blu_spark but idk how to backup vendor_boot as everyone suggests.
Could someone briefly explain how to backup vendor_boot please? When I go into kernel backup in FKM it only asks me for a backup name, does it actually backup both boot and vendor_boot or do I need to something else?
