take a NSTG back to stock

You're talking about a Linux box and mounting noogie served SD cards over USB.
Nook doesn't use fstab
On the Linux box the Nook internal SD card is not /dev/block/mmcblk0, it's /dev/sdb1

After checking the partitions, formatting, that everything mounts and the p1 is marked as boot,
you need to do the factory.zip in CWR.
Then you have to restore all your saved files to the p2 (/rom) partition.
The Nook will not boot without that.

If you have it right you don't need to be re-partitioning and re-formatting the Nook every ten minutes.

Had you restored /rom in your previous attempts?

Apologies in advance - I haven't read the whole thread, but this worked for me:

adb connect <NST IP Address>
adb shell
echo -n -e "\x08\x00\x00\x00" > /rom/devconf/BootCnt
<Ctrl+c to exit shell>
adb reboot

BootCnt is a 4 byte little-endian count of the number of boots.
To make a value >= 0x00000008 is not difficult.
Since echo normally terminates with a NL (0x0a) just send 3 chars of any kind.
(The shell also takes the reboot command.)

YES, YES, YES, YES !!!!!!
leadbella thank you a million times!!
(see this message http://xdaforums.com/showpost.php?p=30430537&postcount=5)

I downloaded the image, and wrote it ot my nook.
By the end of the operation, which took some 9 minutes or so, the process ended abruptly:
error 27 writing to disk at sector 3825664
I opted to ignore it and reboot the nook, just to see what happened. The nook booted alright.

I then booted in CWR and replaced /rom with the contents of my own nook /rom which I had salvaged.
I then booted again, and performed all the process flawlessly.

So far I have registered the device again (no error here since /rom contains my sensitive data. Don't know if it would work if the data was from the original image, since MAC address, device SN and some other parameters would not match), loaded a couple of books and started reading again.

Just in time for another one week shift (leaving tomorrow)

Leadbella you saved my..... nook =)

Thank you, I owe you one.

Same situation/looking for pointers

I've been struggling my way through this post and would love some pointers.

Despite trying to follow the directions for rooting carefully, I managed to make a mess of it, and then somehow dug myself in very deep. My backup was of course no good, and I think I overwrote my /rom partition following directions for using Partition Wizard to try and recover it.

I've managed to follow this thread to this point, where I used ADB to repartition and re-mount the various partitions. I even got the nook to state it was doing a factory reset (and then fail).

For some reason I can't get partition 8 to mount, but I'm not sure if that is necessary to start? The rest all mount OK and have the expected files.

I've tried installing factory.zip and Alpha-FormatTouch-2 and using NSTG-backup-norom. In each case, after rebooting, the nook stops either on the "Read Forever" screen, or "Install Failed".

My /rom partition appears to have 22 files, but I would be surprised if that was my original rom, or it came from one of the above somehow. If someone has a /rom I could try, that would be greatly appreciated. It looks like that's how srgarfi finally a nook working, but the link that was used is no longer valid. I have a nook glow. Any other commands to use to verify things? I'm not very familiar with ADB.

Thanks in advance!

But still the nook does not boot: it displays the CWR screen with a last line that reads "Rebooting..." and nothing happens.
It can be rebooted in noggie and in CWR, but no traces of booting into anything "n".

I quit. If someone shares a complete image of an NSTG I'll try and restore from there.
Else I will order another nook, and get an image from it (and if it works I'll have two devices).

Thanks all for your patience and support, especially Renate =)

Hello all,
I have totally messed up my nook partitions, and now is a brick.
Is there any possibility to find as well an image, like srgarfi on post #91, to restore my NOOK also?
ps: This link as is no longer valid, which I expected that after so many years..
