Note: This feature is not supported on all devices yet. At the time of this post, only Samsung, HTC, OnePlus and other big brand devices work with this. But this doesn’t mean it won’t work on your device. Give it a try and it might just work out fine for you.

How To Restore Backup Partitions

To restore, create a new restore action, and tap the USB icon at the backup selection screen. Then select the partitions you want to restore if present in the backup. Chainfire notes that the backups are created and wrapped in a ZIP file in a specific order, which means that you cannot zip existing backed up partitions created on your phone and restore them through adb.
