There seem to be so many ways to get at the same goal and it's not often clear (to me) whether loose ends have been knotted up for a particular procedure. I love reading on my NST so I have no use for the B&N side of my "new" Tablet. My plan is to try out a few ROMs running from SD card (assuming I get a unit that will boot from said....), find a stable one I like and then flash to internal.
BUT FIRST, I want to backup the stock, unrooted system so that it can be restored, if need be. Someone please take pity on an NT-noob whose NST experience just doesn't cut it here and point me at a working method. Otherwise, it's pin the tail on the SD card for me
EDIT: Woo-hoo! I'm slow on the uptake, but the answer was here all along. digixmax and all the developers that made my new CM 10.21 tablet possible, I thank you!
