ainol have rooted but need to unroot

You can unroot it - or you can return it, since the seller sold you a tablet with a violated warranty (which probably voids the sale - I don't know the laws in the UK, but common law would require that the seller sells you an item that comes with the full factory warranty) and buy one that's not rooted. "It has to be rooted to work in the UK" was the lie he came up with to explain why he sold you what is probably a used, and not-fully-working, tablet.

You might also wish to speak to a solicitor first,to see if you're owed any monetary damages by the seller.

 

Hello Rukbat, you say 'You can unroot it ' but you don't say how. Could you do this please? I have bought a second hand Ainol Novo 10 hero tablet that is apparently rooted using CyanogenMod 10 - 20121220. This prevents me from watching Skygo in the UK. I need to undo the root without killing the tablet.
Any help would be greatly appreciated.
Thank you
