The instruction I followed while rooting did not have step 17a, "Backup Here". Therefore, I am not backed up but I am rooted. Anything I can do now, or is it too late?
You can always reflash the coby update. It formats the system partition and copies its files there. Just make sure you wipe data/cache when you apply any update/rom.
now that you have it rooted if you have a custom recovery installed like clockwork you can do a backup now and have a backup of how your tablet is right now
