[Root] NookManager - graphical rooter for 1.2.x and beyond
This is a graphical, interactive rooting system with the ability to create/restore backups and factory settings.
This has been tested on systems 1.1.5, 1.2.0 (US/UK), and 1.2.1. It will probably work on earlier versions and should be safe to use on future versions. For best results, however, you should be on 1.2.1 before using this tool.
If you've tried rooting your nook unsuccessfully with another utility, it's best to do a factory restore (from NookManager, choose the "Restore" menu and then "Restore factory.zip") and, if your nook came with older firmware, upgrade to the latest 1.2.1 firmware
- Root your nook
- Restore to factory settings
- Disable B&N Apps
- Custom plugins
The actual rooting procedure is very basic:
- uRamdisk is patched to enable ADB
- database setting is changed to allow installation of non-market apps
- the DroidSansFallback font is replaced with the updated font from jellybean to add support for extended characters
- the su/Superuser binary/package is installed
- Relaunch is installed
- ADB Konnect is installed for enabling/disabling ADB over wireless
- on systems running firmware 1.2+, the ModManager jars and package are installed
- on 1.2+ systems, the PackageInstaller.apk from the 1.1.2 firmware is installed to resolve issues with package installers
- and, finally, the Amazon appstore is installed just to have some easy way of downloading new apps
The uRamdisk patching is done with scripts rather than copying pre-compiled binaries, so this should be safe for all existing versions of the Nook firmware and (hopefully) will be forward compatible with any new releases.
The rooting procedure is non-destructive and can be run multiple times without causing problems.
Under the hood, this is a minimal linux environment with the nook drivers/binaries and a few core android binaries. The display is generated with imagemagick and written directly to the framebuffer.
Wherever possible, the parts of this system are compiled from source including the Linux kernel, uBoot, and all of the buildroot utilities. The hardware drivers and associated binaries are extracted from the 1.2.0 upgrade package.
The source for the project, including an automated buildscript is available at GitHub
Support for custom menu items and scripts is documented here.
The download must be unzipped and the NookManager.img file must be written to an empty SD card. On windows, you can use disk imager
. Linux and mac users can use dd.
To run, shut down your nook, install the SD card and power on. You should see the NookManager boot screen followed within 15 seconds by the welcome screen.
After rooting, you can install Google Apps using straygecko's excellent NTGAppsAttack package
if you want to use Google Market/Gmail/Calendar/etc.
