hello everyone.

i've read through this thread but have one questions.

all recovery guides i've gone through assume that there are partitions within /dev/block all my mmcblk* are missing in /dev/block

i tried running the sdcard with Adams image on it and it does boot to a BLANK screen. a little white line comes out first but the screen is blanked but lit.nothing happens even after leaving it running for a day i can run cwm and twrp from sdcard with no problems but both report that all partitions fail to mount.

sgdisk does not allow me to make any changes. i however don't think the nook is completely dead since it does boot up and there is no hardware damage. genptable shows partition info but i can't do anything with that info.

I want to thank you so much for this but I do have one problem after running this. It flashes my nook back to stock which is what I want but when it goes to boot back up my touchscreen to view the "hot to use your nook" video or skip it doesn't work. Nothing on my touchscreen works! The volume turns up. I cant tell if the N button works or not. Help please! Im sooooo close to getting my nook back finally.

You must have flashed multi touch firmware which works only on Cm10 roms. Stock firmware only supports 1 touch.
Make sdcard bootable cwm and flash Cm10 once again (sdcard bootable cm10 may also work) then install the 2 touch firmware, then return to stock.

I had this same problem with mine. I have the NT running completely stock firmware after using Adam's method here. I was running CM10 on sdcard and all works fine with that. But when I try to get back into the stock setup, I have no response from the touch screen at all. With or without my cm10 sdcard inserted. /boggle

Introduction
Some of you might know that I've been working on getting Ubuntu 11.10 running on the Nook Tablet. Why Ubuntu 11.10? It's optimized for touchscreen. My work with Ubuntu is not totally ready yet. The touchscreen is totally wonkey and unusable for touch input.

...Well, without a 3.0 kernel tailored to our device, Ubuntu is quite unusable as a Graphical User Interface. I've tried to compile a few times without any real results to report. The best results I've come across use a 2.6 kernel based on the kernel used for our device by Android. Anyway, if anyone can help get us a operational 3.0, 3.2+ kernel with full support for our device, I can get Ubuntu running.

However, all is not lost. Ubuntu DOES boot on a 2.6 kernel and it WILL perform most tasks that do not require special device control, like wiping the disk and reflashing. I've come up with a total wipe and restore program for SDCard based on ubuntu.

So, as a result of my work, I would like to present the first ever Ubuntu Recovery. This will totally wipe your device. With the exception of the ROM Partition which contains serial information, every single partition will have zeros written to it then flashed with just enough to perform an initial factory reflash. Normally when you perform an update or flash of a device, it is simply formatted. A formatted device can be unformatted. A zeroed device cannot be unformatted. All information is overwritten with zeros.

This will also work if you've damaged the bootloaders or recovery partition.


how to create your own bootable Ubuntu Recovery SDCard


You will need:
  • A Class 4 SDCard with at least 4Gigs of space
  • 6 gigs of free space (for downloading sdcard image and uncompressing)
  • The SDCard Image: http://ge.tt/9rVFXxC?c

Linux/Mac Instructions
  1. Open a terminal in Ubuntu by typing "terminal" in the search bar then hit enter
  2. uncompress the Downloaded SDCard Image
    Code:
    cd ~/Downloads
    tar -xvwzf ./AdamOutlerUbuntuTotalReFlash.tar.gz
  3. With the SDCard or reader removed from the computer, get a list of all disks
    Code:
    ls /dev/sd?
  4. Insert your sdcard or usb sdcard reader, then press the up key and enter to repeat the last command. The new device will show up as sdb, sdc, sdd or sde. each new device gets a higher letter. Note this newly plugged in device.(ie. /dev/sdc)
  5. Use the following command to make your new SDCard, where "sdc" is the name of your SDCard device.
    Code:
    sudo dd if=./AdamOutlerUbuntuTotalReFlash of=/dev/sdc bs=4096; sync
    Wait 5-20 minutes (depending on SDCard speed) until the image burning completes.
  6. Shove it in your nook and turn it on by inserting the USB cable(do touch the power button, just insert the usb cable). Your nook will boot Ubuntu and perform a total factory restore. The process will take 15 minutes to complete with a Class4 micro SDcard.

Pro-tip: to copy and paste easily in Ubuntu, highlight text in the browser, then press the middle mouse button on the terminal.
Pro-tip: The tab key will auto-complete filenames.


Windows Instructions
Thanks to cyberma007 for Windows instructions.
  • Extract AdamOutlerUbuntuRecoveryImage with Winrar
  • Rename the resulting file to Add the .img extension to the filename
  • Download and open Win32 Disk Imager. note: The open source project can be found here: https://launchpad.net/win32-image-writer
  • Choose the drive letter of your SD Card from Win32 Disk Imager
  • Click the Write button
  • Turn of your nook and put in the SD Card and turn it back on.

Your Microsoft®™ Windows©®℠ computer sucks at reading anything except Microsoft formats. It cannot read the Open Source Linux EXT4 format. You will only see one partition after creating the SDCard but it will work fine. If you want to inspect the contents, install a Linux distribution on your computer.



Theory of operation
how it works
When you insert the SDCard and turn on the device this is what happens.
  • The device boots from SDCard.
  • The Ubuntu GUI will load. Personally, I recommend that you do not touch anything
  • You will be presented with a 100 Second countdown
  • If you wish to stop, press and hold power for 10 seconds before flashing has started
  • You will be presented with a progress bar status update only. Closing this will not affect the process. the only way to stop is to turn the device off.
  • At this point, the flashing process will begin
Flashing Process
After Ubuntu has booted here is the procedure which takes place
  1. MLO partition will be written with all zeros, then flashed
  2. U-BOOT partition will be written with all zeros, then flashed
  3. RECOVERY partition will be written with all zeros, then flashed
  4. BOOT partition will be written with all zeros, then flashed
  5. BOOTDATA partition will be written with all zeros, then flashed
  6. BOOTDATA is mounted and a command is sent to factory reset the device upon next boot.
  7. FACTORY partition will be written with all zeros, then flashed in two parts to work around a 120 second filesystem operation bug.
  8. A sync operation takes place to ensure all data is written to the device
  9. SYSTEM partition is wiped with all zeros
  10. SYSTEM partition is recreated as a blank EXT4 filesystem
  11. CACHE partition is wiped with all zeros
  12. CACHE partition is recreated as a blank EXT4 filesystem
  13. SDCARD partition is wiped with all zeros
  14. SDCARD partition is recreated as a blank FAT32 filesystem
  15. A sync operation takes place to ensure that all data is written
  16. You are notified to press and hold power. When the screen goes black remove your SDCard
note: Using a Class4 SDCard, the screen timeout will be aproximately 30 seconds after the entire operation has completed. Do not confuse screen-timeout (blank screen) with turning off the device (black, unilluminated screen). Turn the device off and then remove the sdcard or risk corrupting the data on the sdcard.

It's my intention that this may help someone. This will at least be one more method for people to try before giving up on restoration to 1.4.0. I generally receive 5-10 PMs per week requesting support on the acclaim_update.zip. Hopefully this will reduce those and give people another option to try.

Ubuntu isn't ready for daily use yet, but this recovery tool is more thorough than any other recovery method out there. I need some help porting the 3.0 kernel to the Nook Tablet.
I was able to restore my 16gb NT using the Windows method and some help and advice from a few members of the XDA Community. THANK YOU!

Downloaded file and stays stuck at "writing zeros to MLO". Also tried everything from booting into CWM and flash .zip to it and all I get is
Cant mount/cache/recovery/log
Cant open/cache/recovery/log
Cant mount/cache/recovery/log
Cant open/cache/recovery/last_log


WTF!

I've tried booting this method but every time I plug it into my nook it does not boot. Loads straight into stock Nook Tablet OS. Plugged in with USB still boots to stock.

Other question is I tried deleting the /root/recovery just to use as an operating system but it won't let me access the file because of permissions. I used the chown command to change permission, but nothing happened.

I've tried both Windows and Ubuntu Instructions, but nothing is working for me. Am I missing something? Or something in my process not working.

Default Banging My Head on The Wall Hard

So I have tried making an SD card from windows from Ubuntu and on 3 different computers.

I have tried a 8 GB class 4 san disk card and a 16gb class 10 san disk card. I can get the nook to boot from the card and then it does the countdown from 100. Then it says it is doing its thing and there is a progress bar. The problem is that the progress bar never ever moves. Also it never finishes. The screen blacks out after a while but it never turns off or anything. I have left it for 2 hours and come back to a timed out screen and you press the n button and the screen turns right back on to the progress bar with no progress.

I do not know what I could be doing wrong. I have never been unable to bring a dead android device back to life. Any suggestions are greatly appreciated.

I also have the 10 Touch Firmware installed. And now the screen is unresponsive when restored to original Nook software
So where do I find the appropriate firmware for "One Touch"?
I have looked, but I don't know where it is.
Any help appreciated.
