Only try it if you know how to restore to NC2/NL1. I don't want everyone to jump in at the same time. Let some brave soul try first and report back.

Here's a Mega mirror of the NC2 Odin files: https://mega.co.nz/#F!wg5wRQrQ!vR7a6pze9dgSWjbaRSyhWA

EDIT: Should be stock, so you will have to go about rooting with towelroot and installing busybox and Safestrap.

Walter can you run the Stock install on a NC2 non-rooted/stock device? Or does it have to be NL1?
