It’s easy to root a Barnes & Noble NOOK Tablet if you have a Windows PC. Xda-developers forum member Indirect released an easy-to-use script a few weeks ago that lets you gain access to hidden files and settings on the tablet. Once you’ve done that you can install the Android Market or make all sorts of other changes to the NOOK Tablet.
Now it’s just as easy to root a NOOK Tablet if you’re using Linux or OS X.
Update: This tool requires a NOOK Tablet running software version 1.4.0 or earlier.
Indirect and developers Loglud and Analog have put together a series of scripts that can root the tablet, install Busybox, su, and the Google Android Market and other Google apps. You can use the same utility to unroot the tablet and perform a factory reset.
The tool is called NARS, or NOOK Automated Rooting System, and all you have to do is download and unpack the NARS.tar.gz file, fire up a terminal window, navigate to the download directory and type “sudo ./NARS.sh” (without the quotes) to get started.
You can find download links and more details at the xda-developers forum.
