Second hand tablet.

[WaveyDL]

I've just got a second hand tablet from a friend and unfortunately it's been rooted. I say unfortunately as my friend can't remember what method he used. I'm a bit clueless on rooting though I've done it a few times with older phones with Odin.

Here's my problem. When I try to run software update on the tablet I get "Your device has been modified. Software updates are not available"

How can I remove this root and get the tablet back to it's default state?

Thanks in advance!

Maybe someone could point me in the direction of a forum that would know this?

Thanks!

I'd try xda developers. Good luck

If you have the SuperSU app you can unroot through there. Just open the app, go to settings and scroll down to Full Unroot
