How do I return to stock ROM (currently running Backside) without un-rooting?

I found a bunch of different tutorials online, but most of these seem to be how to return to stock, unrooted status. I just sold my phone on ebay and have to return it to stock ROM so the buyer can activate it.
Thanks!

I do believe u can flash harmonia 2.2 or Leslie Ann's other froyo from sorry it slipped my mind right now those have the ability to reg with virgin I do believe.
Also I think if you update to zv9 it takes you back to stock

Yes. Flash Harmonia 2.2, or the Aenos build(Something like that).

Or even Bumblebee resurrected by Anthony

For the record its the Rhode utility rom. But if your going to be selling it I would flash the zv9update.zip twice and go completely back to stock recovery and all. But once its at zv9 ginger break won't work
