How to restore nandroid? I created a nandroid backup and copied the files to my computer

boot.img
cache.ext4.tar
data.ext4.tar
nandroid.md5
recovery.log
system.ext4.log
ta.img


I deleted the files on my phone to save space and now have copied them back. I used Online Nandroid Pro and not sure how to actually get it to do a complete restore?
To restore a nandroid backup, the device cannot be in "normal operation mode". You have to boot into your (custom) recovery (see our tag-wikis on: recovery-mode / clockworkmod / twrp), from where you can trigger a full restore. With ClockworkMod Recovery, it is e.g. found in the Backup &amp; Restore sub-menu.

Stock recoveries don't offer taking/restoring Nandroid backups. But as you were able to create one, it's pretty safe to assume you've also got a custom recovery installed to your device.
