Question [Q] Nook MAC Address and B&N registration


I installed CWM on my NST, hence I lost the recovery ROM. (should have read the instruction).

I then flashed Tweaked Modded ROM [Feb16] (

The ROM is great but I got horizontal lines across the screen , and would now like to got back to stock.

I have a spare NST, so I can obtain a ROM.

Can you please indicate what device specific information I need to save, in order to make the stock rom work.

ie. location of MACadress and registration/serial details
