Before flashing a custom ROM to my Nexus 5, I made a backup of system, data and cache using
adb backup --twrp; this gave me a 17GB
My custom ROM endeavour went wrong and now I want to restore the backup. When I try
adb restore backup.ab, it seems to only restore the system partition and not data or cache. Output on the TWRP screen:
Updating partition details... ...done Full SELinux support is present. Wiping System Formatting System using make_ext4fs... Restoring System... [System done (190 seconds)] Restore Complete
It completed way too fast to have transferred all 17GB back. How do I get it to restore the entire backup?
Phone: Nexus 5 32GB, TWRP version: 3.2.1-1
