I have a rooted Nova Air and I want to update the system, but my recovery seems to be broken and the recovery image is not included in the update package.
Can someone with rooted Nova Air help extract recovery image for me?
thanks
Step:
- Get su shell
-
Code:
dd if=/dev/block/bootdevice/by-name/recovery of=/sdcard/Download/recovery_backup.img
- (Optional) Generate checksum
Code:
sha256sum /sdcard/Download/recovery_backup.img
