The $199 NOOK HD features a 7 inch, 1440 x 900 pixel display while the $269 NOOK HD+ has a faster processor and a larger 9 inch, 1920 x 1080 pixel display. Both tablets ship with a highly customized version of Google Android 4.0 Ice Cream Sandwich.
Now lets run to the Rooting methods ( Warning : Do it with extream causion- and you are responsible for everything you do )
How its Done ?
B&N left a few basic Android features intact, including an option to enable support for adb (Android Debug Bridge) in a developer settings section. once you’ve done that, you can connect the tablet to a computer with a USB cable, download su and busybox, install the Android SDK (or at least the adb components), and push the su and busybox apps to your NOOK HD or NOOK HD+.
That’s enough to give you root access to these tablets, which will let you adjust files and settings that are normally inaccessible. It’s a first step to customizing the home screen, adding the Google Play Store, or making other changes.
Unfortunately this is the sort of thing that Barnes & Noble could easily prevent with a software update that hides the developer settings. But there’s more than one way to hack a tablet.
Like earlier NOOK devices, the new NOOK HD and NOOK HD+ also appear to be able to boot from a microSD card. That means that you can install a second operating system on a removable card and boot into it any time the card is inserted.
(tested only on 2.0.0 version (as comes out of the box)
NOTE: Currently when you root, the device fails to boot next time, undergoes 8 failed boots and restores to factory. Investigations are still ongoing.
