The NOOK tablet comes with a customized version of Google Android that focused on running B&N apps, web browsing and reading books. Since the form factor is a reasonably priced $249 with a decent enough spec sheet modders have been trying to root the tablet since it was released back in November. The reason it has taken so long to get a stock version of Android running on the tablet is the Nook has a secure boot loader blocking the process.
There is, however, as developers have discovered, a way around the secure bootloader. News has surfaced that the NOOK was capable of running CyanogenMod 9 according to photos posted by Developer Brandon Bennett (Nemith). CyanogenMod 9 is a replacement firmware for tablets and other gadgets based on Android Ice Cream Sandwich.
Nemith isn’t ready to release the tools for running CyanogenMod to the public yet, but he’s making progress with the software and eventually the NOOK Tablet could be an officially supported CyanogenMod-friendly devices. But using CyanogenMod 9 running on a microSD, users can boot from that card and run Android 4.0 Ice Cream Sandwich. That way, the original software from Barnes & Noble is still intact keep them happy while you enjoy Android
