NT factory reset screen with SD CWM - Barnes & Noble Nook Tablet

Bought 2 16GB Nook tablets last week (one for wife) - used indirects method to boot CWM from SD http://forum.xda-developers.com/showthread.php?t=1466583 however got same error as Land Master and a few others where instead of booting CWM the unit booted a factory reset prompt instead. The suggested workaround is to boot while plugged into a computer however this did not work for me. In the end I did get CWM to boot and installed CM7 which is going great on both tablets (I'm in the UK so could not register or use the stock OS).
The workaround for me was, from a failed CWM boot that has gone through a factory reset screen (which is declined) to boot the stock OS,
1 eject SD properly, plug into Mains and reboot then turn off normally (i.e the nook has now been turned off from stock OS without booting from the CWM SD first)
2 re make the SD ( it seems booting into the stock OS with it inserted changed it in some way, no idea how)
3 turn on nook holding n and power button until nook turns - this is standard step
4 insert SD and turn on while still plugged into Mains (nook should have been plugged into Mains from step one)
This worked on both nooks, 1.4.1 out of box with oobe skipped, I swapped the SD after CWM booted for one with CM7, updated from this, wiped data rebooted and have not looked back since.

[Q] Factory Reset Screen instead of CWM - resolved

Howdy,
I restored the NT to 1.4.0, then tried to install CWM via a variety of methods. All resulted in a temporary flash of the white CWM screen, then overlaid by a black screen with a Factory Reset Dialog. I just tried TWRP with the same result. Here is what I did:
1. Removed the SD card.
2. Held down the power and N until the screen turned black
3. Installed the SD card with the NT off.
4. Plugged in the power cord from the wall-wart.
5. White CWM or TWRP screen temporarily appears
6. Cursed Factory Reset dialog appears.
I have searched the forum, tried the different approaches, but still the same result. I rooted the NT once before and had an early version of CM7 installed. I restored to factory after WiFi and root stopped working.
Any suggestions?
Best,
MIke
Resolved - Used Universal Boot Loader and reinstalled.

Nook won't boot up

The story began when I decided to install CM10 on my nook tablet using old recovery that goes for CM7 and eventually broke my partition table and lost my ID(./adb devices shows 0000000000000000). Since my nook refused to boot futher than CWM loading screen (box) i decided to recreate my partitions through ADB using this method and then reflash nook with AdamOutler's Ubuntu recovery (he provided his own mmcblk0p5).
So, I succesfully recreate partition table (everything was in order, I checked a few times) and reflash it with Ubuntu recovery. Interesting part starts here. Now i get "bla-bla-bla please restart your device" and picture with exclamation mark. A couple of reboots gave nothing and brought me to the same screen. Reflash with BN factory recovery as well as factory reset did not work. At that point I decided to inspect partitions again. Everything was ok, formating, size, etc. But my ID still was 0000000000000000. This brought me to the conclusion that something is wrong with mmcblk0p5 and i need to flash partitions with dd again using this files (method). So, all went well without errors, at the end i killed adb server, dismount SD and pressed "reboot device" in CWM menu. And... From that time my nook is completely dead.
It didn't respond to any key. I charge it all night. I tried to hold home+power simultaneously. No response. Connecting to a computer or power outlet is also nothing.
Be kind, I'd like to hear your advice. Sorry for my runglish.

I'm having the same problem. I downgraded from 1.4.3 to 1.4.0. I was able to boot it once and then shut it back down so I could root it. Now it won't start up at all and I have tried everything that I can find to boot it to no avail.
The NT can sometimes get stuck in limbo while booting up, especially with SD-based boot. To get out of it, hold down the power button for 20-30 sec to turn it off then power it on again. Also remove any "bootable" SD card from the card slot; if it boots then the card was not bootable and its non-bootability was the problem.
It's also possible that the NT battery is completely drained (battery readings on some CM builds can be quite off, sometimes as much as 20 points) in which case you'd need to use the BN wall-charger and charge it for 8-12 hours.

[Q] After first boot can't boot again

Hi. I'm running a nook tablet 16gb with latest TWRP recovery and the cyanoboot bootloader (revision nov 23 2012).
I can always reboot the tablet into recovery, fastboot, or just sit on the bootloader screen.
After first installing a rom (either sideload or off sd card) it'll boot into the rom for the first time fine, configure everything, and will work perfectly.
But as soon as I reboot the tablet, the next time the bootloader attempts to load eMMC Normal (the rom) I'll get a black screen with just the backlight on. It will sit on this forever (I've waited about 30 minutes) until the power button is held for about 10 seconds forcing a shutdown.
I have tried booting both with and without an SD card inserted. I've tried installing the rom both with and without an SD card inserted. I've used both CWM recovery and now currently the TWRP recovery. And I've tried a multitude of officially supported CM 10.2 nightlies.
Consider this resolved. I managed to locate a different revision of cyanoboot (even though the original thread no longer contains download links)

[Q] CM 10.2 Boot failure

This morning when I turned on my NT I got the usual flash and initial screen but then nothing (no CM boot animation). Closer inspection (in the dark) revealed a slightly backlit screen so I held the power button until that went out and tried several more times with the same result.
I put in the recovery SD and restored from my most recent backup, thinking the boot image had gotten corrupted somehow. After restoring it booted up fine out of the CWM routine and worked OK. I shut it down midday and then remembered I wanted to do something else tonight. I ended up back where I started! It won't get past the slightly backlit screen.
I've tried inducing it to boot without the SD card (same result) and with the SD card from the OFF state by connecting it via cable to the USB port on my laptop (same result).
I don't know what to try next, beyond the obvious of yet another restore from backup and maybe never powering down again....
Help!
Update: so I left the NT connected via USB to my laptop for an hour or two, after letting it get to the black backlit screen (but no boot animation or any other evidence of life). When I pressed the "N" button it displayed the lock screen!!!!! Everything seems to work but this is too bizarre. Still would like suggestions.
