[Q] Bricked Nook Tablet, Tried Every Combo of Buttons, PLEASE Help! - Barnes & Noble Nook Tablet

Firstly, it should be noted that I'm a noob.
I just bought this Nook Tablet 8GB today. I tried following Adam's post on downgrading a 16GB NT to 2.1.0. Attempting this on my 8GB seemed to be working as it was seemably installing the "update" with a yellow loading bar. It never booted, and its been a black screen since.
I have an SD card, with Adam's UbuntuTotalReflash image burned on it, to boot from, but I cannot tell if the device is on or off. Is there a way to boot it using a software through USB? Someone please help. Thanks.

I am having the same problem, installed the acclaim 1.4.0 downgrade on a 8 GB 250A nook tablet and now it doesnt power on. The computer recognizes it as an OMAP when its plugged in but it does not boot. please help

do not use Adams total wipe wait a bit that meghd00t is cooking something for the bricked 8gb nook tablets, and i be helping with support.
For now try to boot something else from sdcard like cm7 or the new recovery made by meghd00t that is proven to work fine for the 8gb NT.
If you press power button for 20 minutes or so it may power off. You can tell because of the color screen under the light if is black black with no signs of light in a corner then is off but if you see some blue with some light to the top right corner then is not completely off and if that happens it will for sure overheat your tablet.
Hmmm maybe you can use the method to put it in a fridge for 2-3 hours, check it up.
The goal here is to make it boot up even if it's from sdcard only for now.

Try USB BOOT?
No matter what I've done to mine in the past, it would always boot by inserting the USB cable (preferably plugged into charger not PC) with a Bootable SD card installed.

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.

Unbrick without SD Card Boot?

So I have one of those super special 16GB Nook Tablets that refuses to boot to an SD card no matter what you do (see http://forum.xda-developers.com/showthread.php?t=1515761). Since I couldn't use the method of flashing recovery I used on my other two NTs (booting to SD recovery and flashing) I tried using Indirect's recovery flasher (http://forum.xda-developers.com/showthread.php?t=1458630) flashed it, and hit the reboot to recovery button. Now after the initial normal Nook logo on boot a larger one appears and then the screen goes black, I've let it sit for a good 30 minutes and nothing comes up after that (in fact the tablet seems to turn off after a while). I have no access to ADB or fastboot at that point either. Does anyone have any ideas how I can fix this or am I screwed?
Erf, and I made this in the wrong forum... could a mod please move me to the Q&A\Help section?

Apparently this tablet is just super super picky about booting to SD cards... Was able to boot and restore to 1.4.2 using repart.img (mind you it took 5 attempts on 5 different SD cards to do so).

Help, continuously rebooting

I've been searching for a solution to this, but most posts assume you can get into recovery and I can't. In short, I let an acquaintance borrow my rooted Nook running 4.2.2 and TWRP from internal memory, and he called me 2 days later and asked why it is just rebooting to the Nook logo over and over. I got it back and best I can guess he must've tried flashing something though he says he didn't. Anyway, it never gives me a chance to get to recovery, and with it rebooting I can't access it via adb. I've tried several bootable sd images but only once did it even try and within a minute it was rebooting again without trying to run from sd. I've tried a SanDisk 8GBP and a Kingston and an off brand and I can't tell if I'm wasting my time or if someone can confirm that it isn't unrecoverable and help me identify a recommended bootable image and card.
Thanks for any help.

My NT (which was running CM10.1.3) recently while running the usual apps got into a spontaneous CM boot-loop, then as its battery started to get really low the boot-loop got no further than the "N" logo.
I'd suggest you first try charging your NT, then test to see if it would run a pre-made CM10.1 or 10.2 image on SD (available at http://iamafanof.wordpress.com/). If the test is successful, you can the proceed to re-install CM internally following the process outlined at http://forum.xda-developers.com/showpost.php?p=43326042&postcount=123.
FWIW, I've come across reports of similar spontaneous boot-loop incidents on NT and HD+ running 4.2.2, so I don't think your boot-loop problem was caused by your acquaintance doing something he was not supposed to do.
That's good to hear. It doesn't seem to want to charge though because when I plug it in it powers on and then starts rebooting and I can't figure out how to get it to power down. Do you have any ideas?

I'd suggest trying one of the following approaches:
Power it off, put in a bootable SD card (i.e., with a CM SD image, or with boot files and CWM/TWRP recovery), then plug in power cable.
Power it off (by holding down the power button for 20-30 sec) after plugging in the power cable.
[As a last recourse] Let the boot-loop continue to drain the power totally, then plug in power cable to start the charging (you'll need to use the BN power adapter and leave it charge for at least 4-6 hours).
Thanks for the response. I couldn't get those to work straightaway so I burned a bootable CM image to multiple SDs and got it to boot and charge, and then I was able to reinstall recovery in emmc and it's working again. Thanks so much!

CnM Touchpad 7 a10 stuck on Android logo, cant flash rom? Please help someone

Wasn't sure where to post this, so figured here was the safest option - just change it if it needs it!
Hey guys. I've recently bought a CnM Touchpad 7 inch (a10 chip)
It was running fine till i installed an app i believe it didnt like. now when I boot it all it shows is the android logo constantly on loop and wont boot into the OS
So i held down vol + and power on button for 10 seconds to go into 3e recovery
I've tried wiping the cache / reset option but it still reboot and is stuck on the android logo on constant loop
i've tried Recovery (not clockword mod) and there is a boot from SD card, problem is it wont read any micro SD cards I put on it
so because of this i cant put a rom on it to flash it.
I figured as a last resort i'd try connecting it to my win7 pc and hoping it'd pick it up as a USB drive to drag and drop the rom on that way (even without the micro sd card inserted) since it has onboard memory of around 6gb i believe. but win7 dosent recognise it and cant find drivers for it
Any suggestions? I'm really stuck here. otherwise i've just got a bricked tablet.
Kind regards if anyone can shed light on this!

Is it A10 processor or Rockchip??

[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.
