Hi,
Where should I look? I have created an bootable SD Card with CM 10 (also many other flavors as well, so thanks).
This bootable SD image works on one Nook Color, but not another Nook. When the other Nook starts up, it goes directly into the normal Nook screen, and the SD card is readable.
The only obvious difference between the two is the one it works in has never been registered as a nook, while the second one has.
Any help in how to troubleshoot would be greatly appreciated. Couldn't find any settings within the nook itself that seemed to address this.
I also didn't find any threads here that match my issue. There are some where the Nook would boot via SD card, and then stop working, and many about the actual brand of SD card being used, which I wouldn't think is the issue, since this SD card does work in the first Nook.
TIA...Eric

Are you sure they are both Nook Colors? One could be a Nook Tablet. Does it have a silver bezel?

I had to give it back this morning, but I think you may be correct...DUH. I will have my friend go into the "about" screen to tell me for sure. I found a lot of hits on the forum about "can't boot from SD card", and "u sure its a COLOR and not a TABLET?".
At work, I would tell myself to RTFM.
I will confirm, and reply again.
BTW...I want to thank you, leapinlar, personally for your work in the dev forums.
Just confirmed yesterday that it was indeed a Tablet.
Apologies all for the wasted bandwidth.

(BLACK SCREEN OF DEATH)
OK, I have a dead Nook on my hands - non-responsive completely. A coworker of mine bought one of those CM7 cards off of Ebay and it worked fine, but had some connection issues, so I suggested he make a move to PA. Of course, I was the one that was going to do this, so I installed CWR to the EMMC, rebooted, hit N, and booted to EMMC recovery no problem.
Here's where things got stupid:
In recovery, I attempted to install PA without removing the sd card and used the internal SD Card to grab the image. Yeah, I know... Browbeating not necessary... It was taking too long and appeared stuck, and then suddenly the unit just appeared to power down. That was it. No more recovery, the card no longer worked, NOTHING!
Hooked it up to my PC and for a second or two when you hook it up, you can see in the device manager, the Motorola device pops up (I own a Motorola phone, so I assume the drivers are kicking in), and then it goes away. Long press power, do it again, same results. Still no screen, no nothing.
So I figure the 16GB CM7 card (Sandisk SDHC) still has to be useful for creating a recovery card, right? After all, whoever created it originally was able to stuff a bootloader on there, right?
So here's what I tried in terms of tools:
win32diskimager .1 r15
win32diskimager .7
WinImage 8.5
with these, I have tried the following images:
16gb_clockwork-3.0.2.8.img
generic-sdcard-v1.3.img
TWRP-2.1.8-bootable-SD.img
And I used MiniTool Partition Wizard to remove the partitions after each attempt and reformat back to its full 16GB.
The only time a burn was unsuccessful was on the 16GB clockwork with Win32DiskImager - it gave an error stating it couldn't find sectors at 99%. I tried an 8GB image too, but while it burned successfully, no dice.
Alright, so here we are, me at the end of my wits, you reading this tale of woe, and a coworker without a functioning device. The device has charged all night. I owned an NC for years and was mod-happy during that time, and although I had BSOD, I was able to fix it easily. This is a 1 year old BNRV200 (pretty sure they didn't switch up the models).
Help? Advice? WT%#$%^?
EDIT: ADB does not recognize the device when connected.
Go to my NC partition repair thread linked in my signature and follow the procedures there.
Use SDFormatter free on the web for formatting your card before burning one of my bootable CWM images. Don't use partitioning software. The NC is real finicky about how cards are burned. Look at my NC Tips thread and read item A9.

OK, so I used SD Formatter v3.1, size adjustment ON, Full Format (Erase)
Then I used win32diskimager v.7 with CWM-6.0.1.2-bootable_SD - still no boot.
Went back to SD Formatter, rinse, repeat.
Then I used win32diskimager v.1 r15 with same image - still DOA.
Anything I'm missing? I'm going to try 5.5.0.4 in the meantime, but I have my doubts that it will make a difference.

I'm running W8 on all my PCs (doubt that matters?)
Tried 5.5 - no luck.
Switched to a 512mb SD Card, no luck.
Switched to an external card reader (crap one), no luck.
Switched to using external reader without sd-microsd adapter, no luck.
Running out of options here. I gave my old Nook to my dad, so maybe I can go pick it up for sanity checking... I may try these cards in that one just to verify this isn't a full on hardware issue. That would seem strange and highly suspect given this just so happened to occur when I was attempting to install PA. If I can nail it down to that, I suspect it's somehow my fault, and I will need to replace it. If I can't, then I will need to buy a new CM 7 card from Ebay for the guy.
How do you own a Nook for years with never a single problem you couldn't fix, and the one time you touch someone else's, it goes all to hell?

Well looks like their is Three of Us. I have been trying to fix my daughters Nook Color for about 2 weeks now. I have tried 6 different sd cards, my internal card reader and 2 external ones. I have used every version of cw recovery and twrp i can find. I have tried alot of guides. At least the ones that the downloads are still there for.
Heres to pulling your hair out.

Well, here's what I can say (which may be saying nothing):
Back in the day when I had a BSOD on my old device, I was able to fix it by using TheCube's methods. I don't think he hangs around these parts anymore, but I know it was a specific sized SD card you had to have, and a pretty old version of CWR you were flashing onto the card. I remember there was only ONE version of win32diskimager that would work and it was one of the V 0.1 variants (r?). Technology has changed, people have come and gone, and this may mean absolutely squat now. I just know I had this problem on my old one and I was able to fix it that way.
All the links to those items are gone, all the files have been long since lost, and the server I used to use to house those files has long since become a thing of the past.
Maybe B&N has set trip-wires for the modding community in their "newer" revisions? I cut the red wire, and the whole thing blew up.

Leap... Have you tested these methods? If so, can you give me a lead as to which SD reader you used? I'm not above believing that the problem is the multiple readers I have (one is internal, the other is a Chinese plastic knock-off).
I was not able to get over to my parents house to test on their Nook yet.

I use an external USB card reader made for micro SDs so I need no micro to SD adapter. A little red or grey one. I got it on eBay for $2. In fact, I bought several since they sometimes quit working. Then I use win32diskimager with no other windows open. Someone said they even had to update to the latest version (0.7, I think) from sourceforge. Any number of things could make it not boot. NCs can sometimes be very temperamental. But I have never had one I could not eventually get to boot to SD.

Alright... Well here's where we are at this point:
Bought a Dynex 7 in 1 with specific port for MicroSD - burned v6 cwr bootable to 16GB SanDisc C4 SD using Laptop - Didn't work
Switched to main PC and burned 5.5 to 512mb Nokia C4 SD - didn't work.
Both were attempted with latest Win32DiskImager (.7) from SourceForge.
At this point, I'd lean towards a hardware failure, BUT... it's too coincidental that this occurred during a standard CWR install of a ROM. My understanding is that the Nook is supposed to ALWAYS check the SD slot prior to booting internally. Now whether there is a partition block that tells it to do this or not, I've never dug that far, but I'd have to say that this sure makes it look that way.
If that's the case, then the "unbrickable Nook" (which I once believed to be true) is a fairy tale. The fact that several others around here have met with the same fate, I'm almost inclined to believe it. I'm going to go on a hunt for the original files that fixed my first nook. If only I could remember what the heck I did with them.
Scratch that...
I found the files, but now I have an entirely different issue.
My copy of Win32DiskImager back then was very size specific, and although I have a copy of the 16gb_clockwork file I used back then, I can't burn it because Win32DI says the card isn't the right size..
Ugh... I'll keep you all posted.

It is possible that it is a hardware failure of the SD slot. Have you tried cleaning it? The booting to SD is built into the OMAP chip and is not effected by what you have in emmc. It automatically looks at the SD slot first to see if a bootable SD is there. But it looks for specific features of the SD found there to be sure it is bootable. If it is not bootable, it tries the emmc boot partition and if valid boot files are not there, it won't turn on.

Alright, I ended up flashing the old image I used on my last Nook with the same version of win32diskimager I used back then, and still no signs of life.
Unlike the previous issues I had on my first Nook, this one shows no signs of life. No backlit deep black that you can see in the dark, nothing. So I plugged it into my tower PC and held the power for 10 seconds. The install for the OMAP 36xx processor drivers went through the process, but when done, you could not find it in the device manager. So I held the power again for 10 seconds, it showed up for a second, then went away. I repeated this process several times, and same thing each time.
Just to make sure I wasn't leaping to assumptions, I unplugged it and plugged it back into the PC, and no response. Not until I held the power down for 10 seconds again.
So what can we conclude from this? Well, either it is normal for the Nook to show up for a split second on Windows, or the Nook is powering on, then down almost instantaneously. I'm inclined to believe the latter as ordinarily holding the power down for a few seconds wouldn't *reboot* the device, but instead, it would power it down, or power it up (if it was off). Also, unplugging and replugging it in to the PC should have activated the device driver if it was staying on (assuming that isn't a momentary thing on initial startup).
What's the missing piece of the puzzle? I don't know if it's the same for all the other users that have commented, but I don't have the original cable for this device, so I cannot fast charge. A dead Nook will power on, even if drained, when the fast charge cable is used (I believe?). This is something else I will have to try when I get my hands on my dad's Nook. Is it possible that a trickle charge doesn't work below a certain point?
This was kind of my thoughts back when this first occurred - that perhaps the Nook simply lost juice during the install.
Grasping at straws? Perhaps, but straws are all I'm seeing at this point.

I think what you are seeing is the device powering on with the screen off (like it normally does), looking for boot files in SD and emmc and when seeing none, immediately powering off. That is why the brief driver showing in windows. Ordinarily if it finds those boot files, it turns the screen on and continues the boot.

Bit the bullet and grabbed my dads. It's confirmed, the SD card I recently burned works - CWR booted right up. Now for the stock cable test.
Stock cable confirms that the Nook will not power up at all - cable is green indicating full charge. This Nook is toast - so just coincidence that it was during flashing PA? Hard to believe, but haven't I ruled every other possibility out?
EDIT - moved the cable and it turned orange. Coworker confirmed that his Nook charger he was using wouldn't even charge a phone I loaned him. May be on to something here. I'll wait until the cable turns green.
I'm done...
I'm beat. Cable turned green again, and no dice. This Nook is headed for the scrap pile (unless I get a wild hair and tear it apart to re-solder some joints).

I went back to your OP and re-read. It is very common for an installation to screw up and lock up, leaving the boot partition borked. But usually the user can boot to a bootable CWM and re-flash and it repairs it. Ordinarily I would say that the slot could have been messed up for a long time too, since a lot of users have CWM on emmc and would not know it until they needed a bootable card. But in your case the slot was working right up till after you put CWM on emmc. And your using internal memory to flash the zip from and leaving the SD in the slot is usually of no consequence. But it is remotely possible since you left the SD in and the software was running amouk, that it did something to the SD and the slot, like overcurrents or some such nonsense. I still think the not booting from SD is a slot hardware issue since your card boots on other devices and the booting code is in chip firmware.

Hi Everyone,
My nook color is dead - black screen, no matter what I do. I've had it for a couple of years and I rooted it when I first got it. It worked ok, although it seemed like the battery was going dead way faster than it should have. I've tried every solution I could find that looked like it would address my problem, but my device hasn't responded at all. I have wondered if maybe it's the battery, but it doesn't turn on even if I have it plugged in. The little light on the cord will go green when I plug it in.
Any suggestions on what else I can try? I'm pretty close to giving up now. But I really like this device.
Thanks,
Maureen

Maureen,
I had the same problem and resolved it easily.
1. View the video on how to replace the battery at NewPower99. The video is excellent and describes how to take the Nook apart and replace the battery.
2. Remove the back of the Nook after removing the two screws under the microSD cover. You will need a Torx 5 screwdriver to do this. The screwdriver isn't a very common one, but can be purchased from Sears. And it is not expensive.
3. After removing the back cover, do not remove the ten screws or complete the remainder of the disassembly.
4. The battery connector is the biggest connector on the left side of the Nook (Nook is face down andmicroSD card slot on the right hand side.) It has several red and black wire in the wire harness.
5. The main battery connector is a push on connector, so using a small, flat plastic anything, carefully pry the connector up. The connector has a "rubber bumper" glued to the top of it. Leave the bumper on the connector.
6. After the connector is lifted, leave the battery disconnected for around a half-hour or so.
7. Reattach the power connector by gently placing it over the connector and pushing down.
8. Before reattaching the back, power on the Nook to ensure it will reboot. If it does reboot, push the power button again for a half second or so to get the Nook into the sleep mode. DO NOT POWER OFF. I've done this twice now and learned to only put the Nook to sleep.
9. Replace the Nook rear cover. Don't forget to reinstall the two screws under the microSD cover.
10. Keep the Nook charged if possible. It doesn't have to remain on the charger all the time, but keep enough charge on it so it doesn't turn off.
You will find it is actually VERY easy to accomplish this.
I hope this works for you; it did for me.

Before you change the battery, see if a bootable SD will boot. You said you tried every solution, but did not mention that. The NC will not turn on unless it finds valid boot files either in internal boot or the SD boot.

8. Before reattaching the back, power on the Nook to ensure it will reboot. If it does reboot, push the power button again for a half second or so to get the Nook into the sleep mode. DO NOT POWER OFF. I've done this twice now and learned to only put the Nook to sleep.
9. Replace the Nook rear cover. Don't forget to reinstall the two screws under the microSD cover.
10. Keep the Nook charged if possible. It doesn't have to remain on the charger all the time, but keep enough charge on it so it doesn't turn off.
You will find it is actually VERY easy to accomplish this.
I hope this works for you; it did for me.

Thank you!! I will try to boot from sd once more and then will try this and let you know how it goes.

Before you change the battery, see if a bootable SD will boot. You said you tried every solution, but did not mention that. The NC will not turn on unless it finds valid boot files either in internal boot or the SD boot.

Hi! I actually followed some of your links and tried them. I want to try one last time - which of your links should I use? Maybe I did the wrong thing the other times. Thanks a lot.

Ok! I'm excited to give it a shot. Another question: if it doesn't work, should I try it with a different micro sd just in case it's not formatted properly or the image somehow didn't get on there exactly right? Thanks again.

Well, I tried the bootable SD and still no response, so then I changed the battery. Nothing. So I think I'm pretty much out of luck at this point. If you can think of anything else to try, please let me know.
Thanks for all the help,

Hi Everyone,
My nook color is dead - black screen, no matter what I do. I've had it for a couple of years and I rooted it when I first got it. It worked ok, although it seemed like the battery was going dead way faster than it should have. I've tried every solution I could find that looked like it would address my problem, but my device hasn't responded at all. I have wondered if maybe it's the battery, but it doesn't turn on even if I have it plugged in. The little light on the cord will go green when I plug it in.
Any suggestions on what else I can try? I'm pretty close to giving up now. But I really like this device.
Thanks,
Maureen

Quite upset, I had just set mine to run CM 10.1 and it was running great. And now I can't get it to start. I think maybe I caused it by tampering with the SD card on the PC and then putting it back in the NC. But even after putting it back as it was (partition inactive so it should boot from emmc as it had done just previous) I get no flash of light when holding in the power button.
Here's the gritty details of what happened with the SD card. I'd made eyeballer's 1gb boot card and enlarged the partition in mini tools to the full 8 gb, and backed up, flashed and updated a few times to emmc. The installation treats the SD card as "/sdcard", so in order to be able to cold boot emmc, I needed the SD card partition to be inactive. Minitools seems to apply the change (no error), but it was failing (partition was still active when retested). Diskpart also failed to reset it. So I backed up the SD card on the PC, reformatted it with SDformatter, and restored the content. As it happened, my PC restore process made it active again. But this time the partition was aligned at 1024, and Diskpart was able to mark it inactive. Used it in the Nookcolor for hours, it was working great. I was able to boot from emmc for both system and recovery. The SD card was serving as "/sdcard". Then I thought I'd like to set up another Nookcolor we have in the family. So I shut mine down, pulled the SD card, and went back to Diskpart and marked it Active. Put it back in my Nook and it failed to light up or start. Made it Inactive again and it still won't light up or start.
It had a nearly full charge before I messed with it. When I plug it in, the charger light is amber.

Did you check the cord? Those nookie cords fail all the time u know, not very well made. You should get a new one online.
You use those stock nookie cables, not the custom ones or your nookie will not charge good. =)

The Nook Color is different that the Nook HD/HD+. It is much more temperamental about how the SD is formatted. It must be physically set up just right where the HD/HD+ is more liberal. See my NC Tips thread linked in my signature and look at item A9. You should not be messing with the partition with partition management software, particularly the active/inactive and alignment.
Can you still boot without the SD installed?
I have more information for you but need to know that answer first.

I sent a long reply earlier and it looks like it didn't post
With no card I got low battery symbol. Plugged it in. Screen stayed black, not used to that, on CM7 it would light up on its own when booted. Pressed the n button, and got the CM 10 lock screen. It was up to 25% then, now its at 53%. Not supposed to run the eyeballer setup without an SD card, so I haven't tried interacting with it.

Why not? Some apps expect an SD to run properly, but there is nothing wrong with running CM10.1 without one.
If your emmc installation runs fine, your problems are because you were messing with that SD. With the NC it is best to make a small SD for your CWM card and put it away and save it for future use. Then use a different SD for use with CM10.1.
With the NC, if you have a bootable SD inserted without valid boot files on it, it turns on, but does not turn the screen on so to you it looks like it is off.
Your solution to your problem is do what I said above, have two SDs. And don't mess with them. You can get away with messing with the SD on a HD/HD+, but not the NC.

Yes I think working with the HD series nooks made me overly confident yesterday lol
In my missing post I mentioned that it wouldn't boot from my CM7 SD card or a newly burned eyeballer 1gb image yesterday. Before the trouble I had seen my CM7 card boot after CM10.1 was on emmc. Now that the NC is working I'm nervous to shut it down at all or try booting from any SD.
Went out and when I came back the charger was green but the charge percentage said 90%. I switched to a different NC charger. Light stayed green and suddenly it switched from 90% to "charged". On my PC using a card reader, I sdformatted my SD card and did a straight copy paste of the previous folders, leaving off the root files associated with booting, ram disk and such and inserted it in the NC. Disconnected from power. Claimed to be at 100%.
Current readout is 93% and battery time is 28 min 30 sec.
I suppose its possible my battery is going bad. It was chronically plagued with "sleep of death" on CM 7.
I believe I'm running the CM 10.1 nightly of 7/25.
Edit: there are posts that claim you MUST have an SD card inserted to run the eyeballer system. If that's not true I might still need one because I had restored some apps with Titanium and some content had been written there. I think I used apptosd on some of them on sd-based-CM7 in an effort to use my space more efficiently.

My NC is completely back to normal, I've successfully booted using cards that didn't work while I was having trouble. Not sure if it was fixed because I pulled the card to boot emmc as suggested or because the battery got depleted and it went into another state. Either way I'm happy. For now I don't need a torx screwdriver or new battery.
Leapinlar, my eyeballer emmc setup uses an old version of cmw. Its 3.2.0.1. AFAICT it works fine but in other threads I've seen you recommend updated versions. Do you know what changed or improved, and whether my existing backups for stock and CM would be compatible?

The 3.2.0.1 is fine. The only real advantage the newer versions have is they allow backup and restore to internal memory. v5.5.0.4 makes and reads compatible backups with 3.2.0.1 if you choose to (3.2.0.1 is img only, 5.5.0.4 is img or tar). v6.0.1.2 makes a new backup format that is not compatible with 3.2.0.1 (tar or blobs). Therefore, I usually recommend 5.5.0.4 so you get internal backups and can read 3.2.0.1 backups.

My mom gave me her Nook color that isn't powering on. After some research I read about this Black Screen of Death and thought maybe this is the problem. I've read this thread, among others Also read leapinlar's tips page. I've tried the bootable SD card (CWM-5.5.0.4-bootable_SD) but that didn't do anything, which leads me to believe it's totally dead.
After a few hours of research and reading I decide to just plug it into my laptop via usb and press the power & n button to see what would happen. The new hardware dialog popped up on screen and immediately notified me that drivers for omap3630 were not successfully installed (but doesn't show up in device manager as unknown device). Apparently this is the processor of the Nook. Now this has given me hope that the Nook isn't totally dead. I did some more research, in these forums and elsewhere, but couldn't find anything that I thought would help me.
So, has anyone encountered this that might have a suggestion that will help me get this Nook back up and running?
Recap of the issue: Nook does not power on, tried bootable CWM sd card w/no luck, plugged into laptop and it tried to install omap3630 drivers, also no luck. Possible Black Screen of Death.
Thanks!
That life when you plug in means it is not dead, you just need to repair it.
Make sure device is totally powered off by holding the power key for several seconds (8-15). That determines if you are not suffering from the Screen of Death (SOD) or not. If it does not power back up after pressing power again, then it is something else. If it does it was SOD.
If it does not power up again, first make sure it is charged up and then try the CWM SD again. If it still does not power up, remake the SD and try again.
We just have to find the right combination to revive it.

It is definitely charged. I actually had it plugged in for a full day before I got to work on it.
One other question, do I need the original USB cable that came with the Nook to plug it into the computer or will any USB cable work? I know the charger is proprietary

Any microUSB cable will work for attaching to the computer. But you need the stock cable for full charging.
If you tried the above, then your SD is not burned properly. See my NC Tips thread linked in my signature and read item A9.

I tried CWM 5 & 6 using winimager and winimage with no luck. Is there a specific type of card that I should be using? Like a certain speed? I read through your tips again but saw no mention, although I may have missed it. The card I am using now seems to be a fairly generic 2gb micro sd.

I was able to dig up a SanDisk 2GB microSD Card, but I don't know what class it is. I used an old card reader while at work and the microSD card was plugged into an SD adapter. I didn't have my micro sd to usb reader with me. No luck. I'll try when I get home with the other card reader
I still have hope because when I plugged the Nook into my work laptop (Lenovo T420) and held down the power button after about 5 or so seconds it began looking for the driver again.

I recently received a used Nook color from a family member. They had bought a new tablet, and didn't need the Nook any longer. The problem with the NC, however, is it would no longer turn on or even charge. After opening the back (and thus voiding the warranty), I discovered the wires connected to the power button had come loose. I reattached them, put the NC back together, plugged in the charger and turned it on. Everything seemed fine, until I tried to erase it.
I've tried several different attempts, from simply tapping 'erase and deregister' to holding the power and home buttons, and pretty much every other way B&N's tech support told me. Each time, I get the same error message telling me to try again or contact customer support.
Likewise, any changes I make to the Nook (wallpaper, deleting some of the previous owner's books, etc) revert back to the way they were before each failed attempt as well as after simply turning the Nook off and back on.
My computer will not recognize it as a mass usb storage device, nor will it install at all on the computer. Plug in the usb, and it shows up as 'unrecognized'
Finally, anytime I have an SD card plugged in, the NC blackscreens after about 5-10 mins. Requiring a quick reboot.
Now, B&N tells me the NC is pretty much trashed and that I need to upgrade to a new one. I refuse to believe this until I've tried every option I can find. So, if someone can give me any help on trying to get this thing fixed, I'd be greatly appreciated, or if I'd just be better off buying a new tablet. (probably won't be getting a new nook)

All hope is not lost.
Make sure your nook is model # BNVR200. Look on the back cover toward the lower half by the speaker grill. If it is BNT250A/B you have a nook tablet and are in the wrong forum.
If your computer is Windows OS download Google Android USB driver here.
If the nook still has the stock ROM, check by going into settings, about. Latest BN stock ROM is v1.43. If you are on stock BN ROM, try the 8 failed reboots to restore the BN ROM. Instructions are provided by LeapinLar. Read item A12.
The nook could be powering down to conserve battery when a SD card is inserted. It should wake when the n home button is pressed.
The previous owner is the one who should be deregistering the nook, not you. If he/she does not want to do it and you do not care to use his/her media content, you can install CM7-gingerbread, CM10-jellybean, or CM-11-kit kat. CM can be installed on bootable SD or internally in place of the stock BN ROM. Instructions are provided by LeapinLar here.
Whichever CM version you install, make sure to install the correct version of GApps. BN for Android is almost similar in functionality as the stock BN UI. Only you cannot read BN interactive books with the Android BN app. Screen shots of Android Nook app attached.
Of course BN will tell you to buy another Nook product to increase its profits, but we all know better.

The model number is BNTV250 Which a quick google search tells me it's a tablet color. Either way, I have tried doing most of this stuff already before coming here. Failed reboots, booting from an SD card, pretty much everything I could find through a google search.
As for the issue with the sd card, it's not a simple issue of it powering down to conserve battery. No amount of pressing any of the buttons will work. The only way I'm able to get it to turn back on is by pressing the power key for about 20 secs, releasing, and pressing again for about 3 secs.
Finally, a bit of new information. I was finally able to manage to get the nook to install on my computer and give me access to the files. However, I can't delete anything. I tried going that route to delete the old books, however once I eject and disconnect the nook, all the books that were deleted remain, and the books I attempted to add weren't there.

You had better do more than a quick search. A BNTV250 is a Nook Tablet, not a Nook Color and nothing in this Nook Color forum will work on it. There is no such thing as a tablet color. Go to the Nook Tablet forum for your answers.
