[GUIDE] [BRICKED] Loading Roms/CWR via SD Fails - Black Screen of Death (28/02)

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.

All instructions were taken from XDA, plus no guarantee it's the most updated
Moving on, great to hear you've gotten it back to stock. Man, you've got GREAT patience, a couple hundred reboots?
1) Was the SD inserted in or not? Curious about the OS successfully installed message, which is the result of 8x unsuccessful reboots without SD inserted.
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.

Sorry to hear that, and don't give up! Hope you took a look at the other threads, and this little pseudo checklist I made in the OP. Do share the outcome

Thank you Rawfish. The first option, the Dummies Guide to Fixing 'My Nook won't boot'
was what I needed to get started on the right track again. Though I'm not sure anyone wants to know how I ended up here, I'm grateful to those that put in the time and effort to find any of these solutions.

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.

[Q] Refurbed NOOK Color dilemna

The LCD has gone haywire on my NC and I can't see any of the screens to reset it to stock.
I am running MIUI on it, and did the 8 consecutive reboots to get it to boot into recovery, but I can't see the options on the screens.
B&N has the replacement on the way, I just need to send this back per the agreement.
Any ideas on how I can get thing back to factory given that parts of the screen is unreadable?
What would you do?

Use ADB to make it unbootable, just start removing directories.
you can try something like this
Code:
adb shell
format SYSTEM:
format DATA:
format CACHE:

I had the same problem. I used android screencast to help me wipe my nook. It didn't work especially well but it will display the screen on your PC so that you can see what's going on. Unless it's been updated since I did it the screen will be turned 180 degrees and you won't be able to control it from the PC but it will work well enough to help you see what's going on.
http://code.google.com/p/androidscreencast/

Thanks guys...I've never used ADB, but I am downloading the SDK now. Its taking forever.
I think I may be able to figure it out between both of those suggestions.
The only other question I have is about my registration for the Market. I read one place where you should deregister your device before the new one comes in. How can I do that if I can't go into settings?

There's no way to deregister the device without doing it from the device itself. If you do the screencast option you can go through the steps to deregister the device which will in turn return it to factory condition and obviously remove it from your account on BN.

You don't deregister from the Android Market, although you probably want to deregister the Nook from your Barnes and Noble account and you can do that over the phone with B&N support.

I'm stuck.
I can't get Screencast to work because I can't check to see if it's in debug mode or detected by adb devices.
All I see is the boot recovery screen with a bunch of lines going through. The only option that is visible is "wipe cache partition".
If someone could tell me what other options are on this menu, so I can navigate up and down to reset this thing, that would be great.
Like, how many clicks down or up on each screen to completely wipe and reset to stock.
Or, if I just returned on RMA this thing, as is, would that prevent them from sending me a replacement (which I mistakenly though they did already)?
Who has screenshots of all the boot menus?

Bump - any thoughts?

Cant find the right answer, help!

I have found a great deal on a nook color but I need to know if I can deregister it so my daughter can buy from Barnes and Nobel using her own information. I plan on running a rom from an sd card, but keep the main B&N software for her. Thanks.

Really easy to deregister:
From the home screen, press the "N" button and then touch Settings. Then touch Device, then unregister and reset. I'm pretty sure that is the order. After it restores, it will walk you through the setup process again.

Nope that doesn't deregister it.
You need to have the original owner call BN and deregister it with them.

That actually may work. It depends on what condition the prior owner left it in. If he didn't erase anything or password protect anything B&N wouldn't know the difference. If a password prompt pops up then he will need help from the prior owner or call B&N and do a lot of begging...

After alot of going back and forth between the 2, I went with the tablet. I feel once its unlocked (im sure it will be one day) it will be top notch. The processor and the mic did it for me.........Just looking at future capabilities once unlocked.

It has been already rooted. Unlocked? The jury is still out so don't buy it if you will be unhappy if they never beat the locked bootloader....

If you already have a Nook why don't you make a Nandroid Backup and just overwrite the new Nooks NAND with it?
Should work in theory, no?
EDIT: As for waiting for a Nook Tablet Unlock, if you wanted that you might have been better off with the Kindle Fire and it's open bootloader.

[Q] I think I've killed it!

I ripped my SD slot out a few months back after getting a card stuck in it, I threw the Nook in a corner in disgust and left it there,
I've tried to get it back up and running over the last few days, I've charged it fully over two days using the wall charger but it refuses to boot - I have nothing at all displayed. when i plug it into my PC I hear the noise it makes when a usb device is plugged in but that's it - nothing..
So with all the methods of restoring it need the SD slot..I guessing it's a gonna??
Any ideas??

Could try to convert back to stock. There is a 3 finger method of restoring your nook back to stock. You can find the link here in XDA right here. http://forum.xda-developers.com/showthread.php?t=1461172
Then you can take it back to B&N for a replacement if its still under warranty. Don't be so hardcore with losing on game-mode next time

I tried that last night but will try again with a fresh head ....

Nope..not having it, Tried everything now, using the three finger method brings nothing up on the nook screen at all - totally blank although the pc ssems to respond by making a couple of bleeps so assumed this was akin to the nook being turned on , tried it eight times and nothing..I really do think it's dead...

There is a program in the sdk (/tools/ddms) that allows you to see what is on the screen (and take screenshots). I believe this pulls from what the system is pushing to the screen (not what is actually on the screen). If that is the case, you can hit the power button like you normally would to bring up the lock screen, refresh using the application and see if it is pushing anything. You'd have to be quick, because if the NC is in standby, it won't show anything.
Also, you may want to try pulling some logcats to see what is going on.

I think the nook should be unplugged from the computer when trying the 8 failed boots. Also make sure to hold down the power button at least 8 seconds to make sure the nook is really off.

PM me... I can either fix it and send it back... or perhaps we can work out a price to buy it from you.

I have the same problem. The only way I could get it to recognize it was by holding power for 8 seconds and then would go away after a ssecond or [email protected]

Thank you for the offer but I've bought another and might as well keep it for spares, the postage to the states and back alone would cost what I've paid for the replacement.
Or you could tell me how you would fix it ;-)

What I would wind up doing depends a lot on what is on it already, and what methods were used... first thing I'd do is modify ROM's to ensure mmcblk0p8 was seen as sdcard... then go from there...
I wish I could give you a definitive "Do this, then this, and finally this" type of answer... but there are so many variables in place there's no way I can without knowing more of what is there...
If you have a custom ROM on it... go to playstore and get adb wireless

[Q] Nook HD+ (emmc CM) doesn't turn on after water exposure (warranty?)

Hello all,
Been a satisfied user of nook hd+ with emmc. Yesterday, leaking water from my bag soaked my sleeve that I put my HD+, and as a result, I noticed that the HD+ didn't turn on after that.
After a day or so of drying and powering (with no luck), I plugged the device to the charger. Then I saw the green light and the red light flashing multiple times. On the screen, the nook sign turned on as well as the cyanomod introduction screen. However, after that, the device shuts off completely. The system didn't respond to the power button after that, and the charger indicator light didn't turn on after that. I tried leaving the charger on all night but same pattern showed.
I suspected that due to the liquid spill, something happened to the internals that effected the battery.
Now my questions are:
1. Does Nook HD+ deal with spills in the warranty(don't think so)? If not, is there a spill sensor (like the iphone and samsung phones where if it gets wet it changes color, etc) ? Can local barnes and nobles stores deal with device warranty, etc?
2. I remember that warranty also involves the machine has to not be rooted, etc, and therefore will have to be brought back to factory settings. I will have to check, but if I didn't make a stock backup of my own, can I still put an emmc cm10.1 device back to factory settings using the files available in xda? I did register my device via nook servers.
3. As a followup to 1, if there is some drying and/or reassembly required, are there any videos or instructions on opening the cover of the nook hd+? I only saw some videos in youtube for opening the nook hd color, but couldn't find any on hd+.
Thanks to all the help in advance.

I'll answer your last question first. There is an HD+ teardown thread and video here.
Your local B&N store can deal with warranty. They just look up your serial number to see when you registered it and verify it does not work and they will issue you a new one.
But you are right that putting CM on it voids the warranty. If they can see any evidence it has had CM on it they will not honor the warranty. But yours does not power on, so I'm not sure they can tell.
If you did not replace the stock recovery with either verygreen's or my recovery, you might be able to do an 8 failed boot reset, but it sounds like it does not even power on.
And if you can boot to your CWM SD, you can put stock back on it by flashing one of my stock ROMs in my HD/HD+ CWM thread linked in my signature. But I suspect you cannot boot to it.

Thanks Leapinlar for the fast and informative advice. I will follow your steps and update the post if necessary.

Actually, I do have an issue right now though- I find that when I first plug the charger in, I see the "nook", then the "cyanoboot" screen briefly comes up before it shuts off. Now I would have to assume that the BN rep will check by plugging the device to see if it doesn't turn on, and will consequently see the cyanoboot screen. Is there any way I can at least get that screen to just display nook? I have yet to try plugging the cwm sd.

The only hope you have is if you can boot to CWM SD. But that cyanoboot screen gives me hope. You may be able to repair it with that.

Alright, I tried putting in the cwm SD, and what happens is that it gets to the main menu. I got it to the "factory reset", and it says wiping /data.. but after that the thing shuts off. When I take the SD out and restart, sometimes it actually fires up the device all the way to the beginning screen, but then shuts off. During this brief moment I noticed that the battery meter was shown at full.
I also called up the local BN and found out because I bought it at a different store other than BN, I won't be able to get it exchanged- I would have to call and register a claim.
I guess now my main issue now is to wipe out everything somehow, or at least get rid of the beginning cyanoboot screen, so that the corporate nook won't notice this issue.
If nothing I am planning to actually use the steps to open up the casing and attempt drying out whatever precipitation is left and hope that it will work. However, I am worried that they will notice the casing has been tampered with and void my warranty.
Any help and/or more advice will be helpful!

Wiping data does not really help. See if you can flash the stock recovery from my HD/HD+ CWM thread, item 5. Then see if you can flash the stock zip I also have there.
And that is BS about B&N not honoring the warranty because you bought it somewhere else. I bought my HD at Target and registered it with B&N. I had a problem, took it to B&N, they looked up the serial number, saw I registered it less than a year ago and they gave me a new one. Before I did that I had asked an associate there if I needed the receipt and she said no, they just look on the computer, and if I did not have an extended warranty from Target, they could take care of it. And when I came back a few days later, that is exactly what they did.
When you take it in to your store, since they seem to be finicky, don't mention where you bought it or show them your receipt.

Pour some more water into it. With some sugar.
Oops not sugar salt then? Pepper? WD40? (Looking around my humble abode for appropriate "solutions.")

Yeah I tried flashing your zip file, but now the response never even gets to reading the sd card- it just shows the nook icon, then the cyanoboot icon then turns off. Taking the sd card off or back on doesn't change anything.
Thanks for that info involving the bn. I am planning to go to a differerent bn location tomorrow to see if they will see. One thing though- do you remember if they plugged the device to check? Or do they just type in the serial directly? I am just a bit nervous about if they will try to boot it and see the cyanoboot icon and refusing the replacement.
Will update later. As always, thanks for the suggestions.

They plugged it in. I would not take it in unless you can get that cyanoboot off.
Were you able to flash the stock recovery? If so, try booting 8 times in a row without the sd in, it may repair itself.

Unfortunately no, I wasn't able to flash the stock recovery. Before, the cwm boot screen from the sd came on, but now it doesn't even do that. Also the bad part about my issue is that the power button actually doesn't do anything- I have to plug it back in and out for it to show something. (nook icon-> cyanoboot screen, turning off)
I am wondering if opening the cover at this point is the only method left in order for me to get it to respond at all, perhaps disconnecting the battery or looking for wet terminals.. not too sure hwo to do this without making it visually shown that I tampered with it.
But I will also heed your advice and not take it in unless I can get rid of that screen. thanks

Or find a way to make sure it does not boot at all

Yes, open it and disconnect the battery. Lol.
And if you use the right plastic tools, it may never show that you opened it.

Alright, here is what happened. I actually ended up taking the front plastic cover off. The adhesives were a pain to deal with as I took the cover off, but I luckily had some of the tools as outlined in the teardown article you referred me to.
Surprisingly, removing that casing somehow enabled the nook to respond without shutting off.
Fearing that it might shut down again, I quickly used the stock cwm sd with the full recovery zip (400mb file) and reflashed it to factory settings. Now the cyanoboot screen was gone, although the nook screen froze at the 99% mark.
Following earlier advice, I went to a different barnes and nobles(not the one I called and got shot down from lol), and it was relatively okay- a rep actually wanted to see the receipt, but after pressing my case about warranty repairs not requiring it, they decided to take it anyways and replaced it with a BRAND NEW sealed nook hd+. Having the box helped the situation as well, since appraently it simplified the exchange process from their end.
all in all, I was able to get my nook replaced via warranty, thanks to the help here and the files available for flashing!
Thanks again for the help

Set the HD+ on a warm surface for awhile (top of PC, top of cable box, etc.) the heat may help the moisture evaporate.

That is really good news. Glad things worked out.
If your new device boots easily to an SD, you might want to keep stock recovery on there so it can reset itself if there is a problem. Go ahead and put CM10.1 on emmc, but stock recovery allows an automatic restore to stock ROM if things go wrong.

Glad to know your issue is resolved. I also learned from you that B&N has better warranty policy than ASUS. I just sent my nexus 7 to ASUS due to a thin green line on the screen. On the RMA instructions they clearly said water damage is not covered. I had to spend about $10 to ship it back and it is still under repair (status shows repair in progress) after 3 days.

Yeah I might go ahead and keep the stock recovery there so I can indeed reflash if anything goes wrong- obviously it did occur.
Thanks again.
@View92612- actually I am not sure if nook covers it against liquid spills either- in fact, I wouldn't be surprised if they didn't. This was also the reason why I was thinking of opening the device up to make sure there wasn't a liquid spill sensor like many cellphones do nowdays.
Remember also that technically- in house exchange is ONLY valid for devices bought at B&N. It is clearly a store-to-store, situation-to-situation basis, as I have found out (see my earlier posts for proof).
Hope you get that ASUS properly repaired. I remember hearing not so good repair stories for asus and acer products due to repairs having to happen overseas.

Thanks for the reminder. My Nexus 7 just came back with a beautiful, brand new LCD with a part number label. Apparently the easiest way to fix a screen problem is to simply replace with a new one. It went to Grapevine, TX which is right next to the DFW airport. I hope my Nook HD+ would not have a similar issue later. But having a B&N store nearby(about 5 minutes from home) is quite helpful in such scenarios...
