Team Win Recovery Project (touch-based)
You MUST have a “rooted” Nook for this application to install and run. If your device is still “stock” and you are booting into Android with the SDCard, you must ROOT the device first before trying this. For an introduction to rooting and descriptions of other options, see our article… Intro to Rooting & Modding Nook Tablet. Use our guide to root ANY Nook Tablet: http://bishoptec.com/2012/09/root-for-nook-tablet-1-4-3/
The video explains how a user can install the TeamWin Recovery Project application to the internal memory (emmc) of the Nook Tablet.
TWRP is a drop-in replacement for CWM Recovery. Both are good but CWM is text/menu based & TWRP is “touch & click” based.
Although I like the touch function in TWRP, a more important reason to install it is that it is ROM-agnostic. CWM is picky about which versions will flash which ROMs – especially on the Nook. But TWRP will work with practically any ROM that is compatible with your device.
Everything is done on the Nook its self…
Most posts on XDA suggest that you use Fastboot to install/flash recoveries (either TWRP or CWM) to the internal eMMC of the Nook. This is fine. However, it is a bit more “technical” and some users have experienced problems with the process. Also, in most cases, you MUST have the Cyanoboot program installed to accomplish it. Our process (below) is simple, easy, and does not even require an attached computer.
Install the Goo Manager (GM) app from the Play Store. This app requires that your Nook (or other device) be rooted and, when first executed, will ask for root privileges. After that, follow these steps:
- At the main screen for GooManager, click on the Menu button and select “Install OpenRecoveryScript” (or, just click on the “Flash ROMs” menu item. When the dialog asks if you have a recovery, click on “Try to find one for me”)
- Answer the remaining dialogs to allow GM to install a new recovery.
- Be sure to have an SDCard in the slot – the download may fail if you do not.
- After the file is downloaded, it takes a minute or two (little or no feedback) for the recovery.img to install.
- When the install is completed, there *IS* a small dialog in the bottom half of the screen, stating that the recovery was installed.
- At that point, you can return to the menu and select “Reboot Recovery” to get started using TWRP.
- Alternate RECOVERY options: You can now download FLASHABLE versions of either ClockWorkMod (CWM) or Team Win Recovery Project (TWRP). Just flash one of these to the INTERNAL memory just as you would flash a ROM zip. No need to clear or wipe any partitions or caches.
Note that sometimes the Nook may not do a full reboot and only turn off. If the screen goes dark for more than a few seconds, just hold the “n” button down while powering on – and the device should enter recovery. If the Cyanoboot program is installed, just continue to hold both buttons until you see the line stating “rebooting recovery.”
The only issue I have seen is when I use the “Menu”? button at the top, it will not scroll all the way to the bottom of the log. Looks like it might only be one more line?
