My nook was rooted and I was happily using it for about 3 weeks.
It was a ver. 1.0.0 model.
One night I went to turn it on and it wouldnt come on. I thought somehow the battery must have drained out. I plugged it in when I got home, but after a while I tried to start it and it still wouldnt.
What I have noticed is that the backlight comes on, changes intesity a couple times, goes off and then comes back on, like some sort of loop.
There is no message screen or N screen. There is no booting from SD, as far as everything I've tried to burn to SD and boot from.
I've tried all the key combos, some result in different variations of the backlight sequence but nothing else.
I think it is caught in some sort of loop before looking for any bootable system.
I want to try everything I (and everyone else) can think of before I go to the trouble of shipping it back to B&N.
Can you put the original stock system on an SD, even though I doubt it would boot from that either, but just a thought.
Thanks,
Phil
Looks like you are going to be enrolling in the NC advanced class. I really can't help on this but this weekend I plan one doing a the group install internally and I should be knowledgable afterwards.
Start by looking into creating the froyo image one a sdcard. There is a thread. The NC should be able to boot from that card. If it does great. Now look for thread about recovering images and using dd to write images. Someone did post the stock images 1.01
have you tried booting Nookie Froyo through an SD card? Then you could probably flash a stock rom (zip is in the forums) and restore.
Froyo
Yeah, I have Froyo on an SD card right now. Doesnt make a difference.
I have pretty much run out of things to try, unless there is some new, secret key combo that fixes everything.
I really don't think its even getting to the OS, I think I must have some real hardware failure that has nothing to do with the stock or rooted OS.
Sounds like it may be time for a warranty claim...

i agree, if its not even getting to the point where it can boot from sd then theres nothing that i can think of that will work, at the point your at i dont think it can recognize any button input or usb data as there literally is nothing it knows how to do
Is this possibly the first successful Bricking?
I hope not!! Keep us posted on what works and what doesn't work.
Good luck, mate.
Cheers!
Received new Nook Color.
Well I did a warranty claim.
It was a very long wait on the B&N help line. I hung up and used the online chat window. That was a very long wait as well, about 25 minutes, but I finally got through.
After explaining all the things I tried and what the nook was doing, she wanted me to hold the power button for 10 seconds. I was like, "Ok, I've tried holding it for several minutes at a time, several hundred times, but what the hell." Then she wanted to know if I dropped it or not. Mine was pristine though, not even a scratch.
So finally she said I qualified for a replacement.
The deal is they give you a ups shipping label and they ship you a new Nook. If they determine that your nook got wrecked because of your own stupidity or whatever they bill you for the new one. She said the new one would ship the next day, but it didn't ship for over a week. I shipped mine the next day with the label they sent me.
So now finally I have my new nook. I haven't rooted it yet, though I probably will. I don't believe my problem was ever related to the software things I did, I dont believe that could wreck the hardware.
Also I never mentioned rooting it or anything.
Did you try burning CWR onto a SD card and seeing if it boots?
As we know, the Nook Color's SD slot will always take first boot priority. I'm in a situation where even booting via SD through known methods are not working.
The purpose of this thread is to:
1) Share with others who are in this similar situation, on methods which may result in the recovery of their own devices
2) Keep this discussion healthy so one day, I will be able to restore my own bricked device which I'm still striving hard to.

IMPORTANT: If you have a bricked device I need to emphasize on searching and reading very carefully what others have shared here in both General and in Development. This is a fundamental requirement, as with the ability to follow instructions and not panic by creating unnecessary threads. This will only make things harder to find, so thank you in advance for not doing that.
There are many useful guides out there, some of which the most helpful are:

Anyway, in severe bricking cases where hardware is not at fault, many of the solutions to restore the NC begins with either:
1) Booting to CWR-SD via uSD
2) Booting to a rom i.e. Nookie Froyo via uSD
3) Having ADB access, if available
Till date I am not sure why the SD-loaded programs do not work for me, and here are the symptoms:
1) Without SD inserted, the standard BN splash appears, 'Welcome to the Future of Reading', then gets stuck there till powered down. Needless to say, the 8-times reset method doesn't work.
2) With SD inserted, the 'LOADING' screen will splash, then screen blacks out with device still powered on . You will know that the device is still running as you need to hold power down for around 20 secs before you're able to power it back up again. I call this the 'Black Screen of Death'.

To get your device up and running, try the following:
0) Do not panic. As long there's no hardware failure there will always be a solution. Look at me, thing's still a damn brick and yet here I am, still hopeful
1) Perform a search, read the useful threads created by the above members first. This thread is related only to failed SD-booting.
Once you've done that, prepare your recovery options with these in mind. The elimination process is part and parcel of problem-solving. In no particular order:
2) Sometimes, try powering on your device by connecting the USB cable from your PC or A/C source, instead of using the Power button.
3) Use only the original USB cable that came with your device.
4) Use the back USB ports of your PC, instead of the fronts as they may provide more consistent power and connection to your device. Try to avoid using USB hubs as they may not distribute the required power equally/properly.
5) Try switching to different USB ports, some may be hardware-gimped due to wear-and-tear.
6) Try to attempt the recovery on another Win, Mac or Linux computer. At least eliminate further possibilities of environmental hardware error.
7) Try charging the battery full.
8) Or, try discharging the battery completely, by leaving the device in BSOD state overnight until you get a message saying your device can't boot due to insufficient power when switched on. Once you are in this state, keep booting the device up until the screen does not appear. Then, recharge it back to full to see if the OS returns to stock (I am sceptical of this, but this was what others advised).
9) Try different SD cards. The device could be picky. Variety should be by class-type, brand, SDHC or non-SDHC. It's been discussed that faster cards perform better, as with more reknowned brands. Also, 16GB cards reportedly do not run Froyo (do read more by searching).
10) When loading anything via SD (CWR, roms), try different button combinations i.e. power + n + up, power + n, etc.
11) And/or, hold power for various timed-presses i.e. >30 / 45 / 60 seconds. Some members report CWR booting up after these periods, or even longer.
Note: funnily I tried holding power + n + up for > 60 seconds and the 'LOADING' screen just stays frozen. Still doesn't work, and I didn't get any ADB access.
12) Try formatting the card completely with native Win/Linux tools, EASEUS Partition Master or SDFormatter before each burn.
13) Try using both Win32DiskImager and WinImage, or dd-ing in Linux (search for more instructions). If you have Linux, you can check to see if the SD's /boot partition is indeed bootable or not.
14) For ADB access, try to unregister your hardware (go to Start > Run > devmgmt.msc), then unplug-replug device to have your PC detect it again. If a device with VID of 2080 shows up, that's the NC. You should know what this means, by now. If not, read more here.
15) Try different SD card readers, especially when experiencing failure on multiple computers. As opposed to multi-adapters i.e. 6-in-1s, try dedicated microSD readers like this one. Do not use those microSD-to-normalSD converters (usually packed together in the same shipping plastic as your card) just because you only have a reader that reads regular SD cards, they tend to fail a lot.
16) At your own risk, try cleaning the contact points on your SD cards (if you must, use cleaning alcohol and a cottom swap/q-tip - do not use water), to free them of dirt and invisible grime. If you have multiple SDs, try cleaning the least expensive ones first. Don't forget to leave them to dry completely before insertion into the NC. Credit to bonobomidwest, read his experience here.

17) Use Nooter 0.2 (recommendation from thecubed):
Here's my recommendation: use the stock charger cable (the one with the light-up N in it) when you try Nooter 0.2.
If the light goes from orange to green (or something like that) that means Nooter is booted and working.
My new thought: some file in /rom is missing, which controls the backlight and lcd controller. I can't prove this, but it seems logical haha.
All you need to do is get Nooter 0.2 booted and ssh'd in and you'll be able to dd over a complete 1.0.1 backup.
rawfish: I use Ubuntu, so sorry if I'm not able to provide instructions for Windows
Type:
Code:
sudo ifconfig usb0 192.168.2.1
Then:
Code:
ssh [email protected]
And you should be able to follow the directions for restoring on the wiki... either that or check around on IRC, if you tell them that you've got ssh access and you just need to restore your device, they'll help you out if I'm not around..
rawfish: I typed 'dmesg' in shell to see if the NC connected as a usb-ethernet device, and it doesn't show. If it does for you, then you should have progress and should ask around in IRC.

All these did not work for me, but hope this is useful to some. I've read testimonies from everyone that this is an unbrickable device, and I certainly hope it's true, and for a kind soul to help suggest more solutions. As I'm overseas, do you think I should call BN up to see if I can arrange to send my device back for fixing/replacement? It's been a month since purchase, and 3 weeks of failed restore attempts.
Disclaimer: I am not responsible if any of these methods get you in deeper trouble. Attempt at your own risk. Credit goes to thecube aka IOMonster, and the #nookcolor channel on irc.freenode.net. Thank you to everyone who created the recovery guides too.

You sure you just don't have crap or badly burned SD cards? Sounds pretty much what happens if you boot s really slow/junk SD or burn it badly.

I tried on 6 different SD cards:
1. Transcend 8GB Class 6
2. Transcend 4GB Class 2
3. Wintec 16GB Class 10
4. Sandisk 4GB Class 4
5. Sandisk 2GB non-SDHC
6. Sandisk 256MB
I've burned stuffs like Autonooter and Honeycomb on these before, and they worked fine.

First of all - great job in pulling all the resources into one place (it's small consolation, but i think you've just helped a whole load of people )
Second, i apologise if I'm telling you stuff that's obvious, but in helping out on these forums often it's the LOGIC of troubleshooting rather than the particulars of the problem that are important... In other words, only vary one thing at a time, and ALWAYS swap out every piece of hardware involved at each stage... if you always rely on one piece of hardware this might be the weak link... so have you tried a different SD drive or adapter? and have you tried burning from a different computer?
Now, I'm not being insulting, because I had a virtually identical problem with my first froyo - it just wouldn't boot (as you describe) despite multiple burns, different cards, all of the standard formatting tricks etc. It wouldn't work in multiple computers - the common element being the SD/microSD adapter. It never occurred to me that such an electrically simple part could be at fault, but you bet it was - in fact i would say in my experience these things consistently fail! (I spent a day kickign myself, because we know ho unreliable they are from using them in other devices). They also all look alike so it's hard to keep track of which one you are dealing with They also fail unexpectedly, so if you used an adapter before there's no guarantee it's working now...
Sooo... Have you tried a dedicated microSD reader (rather than a simple adapter)? I now carry one with me everywhere (it doubles as the world's smallest thumb drive too)
http://www.amazon.com/gp/product/B002HGFKR8
Also bear in mind that froyo appears not to work on 16gb cards (i see you tried one)
Also, from my experience with other devices these cards are very sensitive to dirt and oil on the contacts. Certainly with enough frustrated handling you can get enough finger-grease on them to have them fail. Also they seem to be much less tolerant when writing than reading. I have NO idea how you would go about cleaning out the slot in the NC (and as someone who has ruined at least one DVD drive by blowing canned air where you shouldn't I'm not going to advocate for that). I have resurrected 'dead' SD cards before by cleaning the contacts with rubbing alcohol and a q-tip (on the card's contacts) - but again do so with great care (at your own risk!!!) and with your cheapest card, and make sure it si completely dry before you put it in the NC.
I have been generally a little scared that all this plugging and unplugging of the microSD might hurt the NC, so i have done everything i can to avoid that...
I am sure you can find someone local to you willing to help fix your boot issue but I assure you, its damn near impossible to brick a nook without physical damage.
@bonobomidwest:
No offence taken at all, in fact I am very appreciative of your contribution. I forgot to add the fact that I tried on 2 different card readers, plus indeed tried to clean the slot via an air duster VERY GENTLY as a last effort resort (I would not recommend this, it may cause permanent hardware damage). Once I'm free I'll go get a new SD reader (reads uSD only) and a new uSD which I haven't tried before. I'll try cleaning the contact points too.
*Thanks - I've added more checklists to the OP
@combustiblemonkey:
Thanks for the assurance.
I convinced my friend to buy a nook, rooted it for him, and was bricked within 2 days. Here is how I fixed it
EDIT: I tried to post a link, but was unable. If you go to theunlockr(dot)com and search for how to restore nook color to stock, there is a detailed article.
This took me almost 2 days of reboots, black screens, and freezing. I would get into CWR, and it would freeze. Had to reboot, got the black screen of death. Literally, a couple hundred reboots before it said that the OS has successfully installed, and of course, it froze again. Many more reboots, and it was finally at stock. I figure getting it back to stock was enough to return it.

2) Could you also provide a more detailed account on what you did? Looking forward to hear - thanks.
Hi rawfish
I also have this issue and have been trying many things. My nook did boot nooter 0.2 (the light went green) but I couldn't get Win 7 or Ubuntu to connect to it. My screen never changes at all, no backlight even. Seems this may be a larger issue than most believe it to be, especially for people like us who don't live in the US.

If you can find a friend or person in your area having the same device, you can try to see if an SD you burned work on theirs. If it works on theirs, it's possible that your SD slot is defective - but then comes the question of it being in working condition before the bricking happened, right?
I still think mine's recoverable, as with yours. Could be a bad SD or reader, or bad contacts. I'm going to try out using another reader plus purchase an el-cheapo branded SD. I'm also going to try formatting it via another PC in a linux environment and messing around with the partitions.
I understand the trouble you may have taken to get the device - and this happens. All the best mate, and do cheer up, don't give up.

When I finally got it to work, the SD card was installed with the 1.0.1 stock OS on it, and CWR. The problem was that that (+) and (-) would only occasionally work. And if they did, it would usually freeze. I would be able to format system, but it would freeze if I tried to format data. Powered off, and I would get the black screen of death (BSoD). Once this happened, I would plug it into my computer so that I could hear the chime indicating a new device was plugged in. I found that ejecting the SD and then rebooting would sometimes help get rid of the BSoD. Then another power down, plug in the SD, and start again. Also, holding the N, +, and Power would sometimes help in launching CWR. I would usually have to hold for 60 seconds, but it would finally launch. It seemed like the nook was trying to run a process that slowing it down and causing it to freeze, but I couldn't figure out what it was. If I would wait an hour, it would boot CWR and allow me to format system and data, but then it would freeze when I would try to install the zip.
The successful install message was in CWR. It said Install From SD Card Complete, or something like that. After that, I still had to do the 8 reboots. It would load up the stock welcome screen and freeze. 8 reboots later, I got the video lady. Good enough to return it to the store.
It really was just persistence. It would usually take an hour of reboots before I was able to try to install the zip, and it probably failed on me 15+ times. The status bar would get half way, and freeze. Then I had to begin again. If it had been my nook instead of my friends, I probably would have given up. I wish I could be more specific, but unfortunately I am new to all of this. My nook rooted just fine, and fixing his is really my only experience with CWR. I just kept going until it worked.
Good luck! It is a pain in the ass, but it can happen.

My wife has one as well so am able to test using that and the SD works fine in hers. The whole screen not turning on thing is weird though, does your screen turn on?
We bought them when on honeymoon in America so didn't have to pay a shipper or anything
Deleting the partitions manually with Gparted and using dd to burn the SDs and making sure the correct partitions are bootable doesn't seem to work. Last night I retried a lot of the previously attempted options, with no results.
It's weird to think that a working SD slot and a slew of cards will suddenly malfunction, but for now that seems like the most plausible reason why my NC can't boot anything off SD.
To think back how it all started, the device suddenly rebooted from HC preview v0.4 to stock BN 1.01 (rooted + installed CWR on eMMC) while the SD is inserted, then upon another reboot it simply stays dead, this gives me reason to believe that the internal boot partition is corrupted, and SD slot nuked hardware-wise.
Hmmm, really hoping to find someone else who has the same device, in my area.
Right now I am at the Black Screen of Death as well...
I think Barnes should refund me, but I am willing to do some tests for the good of society.

Update:
Ok, so after running through it, I ended up getting stuck on the boot screen that shows N. If I powered off, it would restart and get stuck at that screen. I tried the 8 shutdowns (it installed new software), but afterwards, it was still stuck. So, I tried another method I found on the forums. I powered off holding the N button and power, which caused it to boot back up and do a factory reset. I now have a factory fresh Nook.
Okay, it's been a while since I kept this thread updated - I contacted BN and had the device sent back, apparently the SD slot failed so they sent me a new one. I'm just wondering if it's sheer concidence that it happened, as I was tinkering with Nookie Honey preview v0.4, when the hardware suddenly failed.
Oh well, I guess the NC still remains as a 99.99% unbrickable device - with the 0.01% being related to the ambiguous root cause to my case.
I now have 2 NCs (one from the RMA process, another one from the $199 eBay deal.
I recently switched over from CM10.1 to LN14.1 and have been getting misreported battery (it worked fine previously) Specifically, it will drop 15-20% every 10 minutes or so, and stay at 1% for several hours (I've recorded up to ten hours).
What I've tried to fix the issue:
Draining to 0% and recharging to 100% (i.e. manual calibration listed on XDA) on LN14 builds
Battery Calibration Apps recommended on XDA
Flashing down to stock ROM, factory resetting, and re-flashing 14.1 (I read this could restore a battery file that has been affected by repeated flashing of ROMs.)
Flashing back down to CM10.1 and CM10.2 (also tried CM11 and CM12 builds) that I used previously
Wiping DALVIK/Cache between each install
Battery Monitoring Apps (Rooted)
Battery saving/hibernation apps
Adjusting nearly every power consumption option (screen brightness, WiFi, etc.)
The behavior has been the same switching between any ROM of CM, LN, Stock/Factory Reset from the point that I first upgraded from CM10 to LN14.
I don't think it's a lack a capacity and it has to do with misreporting.
I haven't tried recalibrating/draining on CM10 or stock, but I don't know if that would be pointless since I've attempted it three times on LN14 with no success. Also, I don't know if the process causes battery issues long-term. Right now, I'm looking to see if TWRP reports the same battery level as LN14. Last night, I was at 1% for 10 hours or so, including ~3 hours of video trying to discharge.
Anyone have any tips on where to look next? Is this just an issue with LN on HD+ in general? Thanks in advance for any help.
Probably one of your sources of information is this post: https://forum.xda-developers.com/nook-hd/help/nook-hd-battery-issue-custom-rom-fixes-t3389721
We suffered through this issue with an HD for quite awhile and tried all the stuff you mention. It may be that the return to stock/factory reset actually worked but it may also be that we discovered that somehow the SD card we were using for flashing (and which we had remade at some point) had not been properly configured as 0x0c and was instead 0x0b. This eventually led to a tablet that would only boot when plugged in and allowed to sit for a minute before being unplugged. We never got to the battery misbehaving issue at that point because of the panic that ensued over what the %#W% was going on!
Anyway.....once the card was made properly, we started from stock/factory reset (including actually re-registering the tablet with B&N, etc.) and then flashed the CM ROMs. Everything is now fine.
Whew.

I checked my SD card and the Partition ID is 0x0b. However, my tablet doesn't have the behavior you described regarding the need to be plugged in to boot.
Are you indicating that it would be worth flashing back down to 2.1.0 Stock ROM/Factory Reset with a 0x0c card, and Registering to attempt to resolve the issue? Would I be required to remain on stock for a period of time or can I re-flash to LN immediately? Thanks in advance for you help, the Partition ID type is news to me.

I'm no expert so my information is anecdotal. I'd never seen the weird behavior like on the HD tablet in all my work with an old Nook Tablet. And I can't pinpoint the battery reporting issue vs. the improper remake of the card. All I know is that at some point I thought there must be something wrong somewhere and decided to make a completely new card. Then the "fun" really began.
The actual correct Partition ID type is 0x0C FAT32 LBA (as shown by Minitool Partition Wizard). This is documented in all (most?) of the instructions for preparing SD cards. I just got sloppy, I guess. It's still difficult to believe that this change made the difference but it did for me, at least in terms of boot. I do think the return to stock is a good idea. It may not be necessary to register (we already had an account from the old days of running stock), but I would do the factory reset and let it sit awhile as the OP suggested (maybe 15 min?). As he said, what's a few minutes if it will save you endless headaches? What do you have to lose?
When I (carefully) prepared my new SD card I used the files provided by @belfastraven, substituting the old version of CWM needed to reflash stock for the one he had. This gave me SD-based TWRP (two different versions) as well as the old CWM. For the life of me I can't relocate that post, but I expect other card recipes will work.

I'm no expert so my information is anecdotal. I'd never seen the weird behavior like on the HD tablet in all my work with an old Nook Tablet. And I can't pinpoint the battery reporting issue vs. the improper remake of the card. All I know is that at some point I thought there must be something wrong somewhere and decided to make a completely new card. Then the "fun" really began.
The actual correct Partition ID type is 0x0C FAT32 LBA (as shown by Minitool Partition Wizard). This is documented in all (most?) of the instructions for preparing SD cards. I just got sloppy, I guess. It's still difficult to believe that this change made the difference but it did for me, at least in terms of boot. I do think the return to stock is a good idea. It may not be necessary to register (we already had an account from the old days of running stock), but I would do the factory reset and let it sit awhile as the OP suggested (maybe 15 min?).

I just flashed down to stock, factory reset and reinstalled 14.1 I set the SD to 0x0C FAT32 LBA. I didn't wait 15 minutes after installing the stock though, just a few minutes (I missed this step and hopefully it doesn't make all the difference.) I'll report the results on usage.
I flashed down to stock with NookHDplus-bootable-CWM-6028-for-stock-BOOTFILES-r4-(05.15.13) posted in a CM10 thread though.
The early indication is that the issue is still the same. I think I'm fighting a losing battle and I'll have to look into replacing the battery or making a regular habit of keeping the tablet plugged in.

Like most Android devices, not it's not made to be opened up.
But it's doable with care. If you search you can find instructions and videos.
But, 1, I'm non convinced it's a bad battery. You get too much runtime at 1%
And 2, not sure of any good options for replacement batteries. That's why my wife's HD+ doesn't gave a new battery.

I'm considering opening it just for the sake of seeing if there's a bad connection, but I've seen people damaging the case, etc. I agree with your sentiment that the capacity doesn't indicate it's a bad battery. Regardless, I'm grateful for everyone's help here so far.

Some people just shouldn't work on finiky stuff. I;ve seen people screw up lots of things because they rushed.
Phones and tablets just require time and patience.

I'm assuming you've opened a few, so do you recommend a special set of tools? Or is a guitar pick and appropriate screwdriver enough?

Not sure on these.
I've got a few plastic spludgers that have been handy with other devices.
This one makes it look easy, but the tape on the bezel is missing.

Also they don't even tape the replacement battery to the back so it might shift around in the case.
This is more like what you'll encounter.

Note all the double sided tape. You'll want to preserve it replace it.

Do you have any suggestions for a replacement brand?
I found:
https://www.amazon.com/TLP-040-Li-P...d=1510605819&sr=1-4&keywords=nook+hd++battery
but I thought someone with better experience could make a suggestion.

As I said earlier, no. I'm not confident any of them are any good.
Someone posted a link to the one they got in the other thread.
