[Q] Unable to boot my ~unmodified~ Nook Color from SD card.

I just got a refurbished Nook Color. Seems to work fine but you have to push the power button hard to click it.
Haven't rooted, installed roms, anything yet. But I can't get it to boot from my SD card. I have a 4GB (class-4) microSD card. (I have checked the sdcard for bad blocks using the linux "badblocks" command.) I have followed instructions detailed here:
glasskeys. /2011/06/27/how-to-make-a-bootable-sd-card-running-cyanogenmod-for-the-nook-color/
and here [note - new users are forbidden from posting links here - in the above and below links, I left out the "com" after the dot in the website address]:
nookdevs. /Nookie_Honeycomb:_Burning_a_bootable_SD_card
. I use Ubuntu Linux 10.11 "dd" command to write the .img files to the SD card. However, once I write the SD card and put it into my Nook, the nook won't turn on. Just won't turn on. As soon as I take the card out and try again, I can boot up the nook to the locked-down, walled-garden stock Android on the device.
Help! Is something wrong with my SD card, or with my device? I have a 2GB microSD card somewhere I can find if I need to...

Re:
Can anyone help me find the source of the problem? Is it my SDcard, my card-burning technique (i followed the dd instructions word for word), my computer or is something wrong with my Nook?

What I might suggest is to discard your original source of instructions and start fresh. Search the xda forum for clear information on 1) proper mSD card to use; 2) proper card burning software; 3) the most appropriate rom(s) to use for what you want your Nook to do for you, and 4) if necessary, very explicit instructions to troubleshoot any problems you may encounter with your processes. I'll not point to specific locations here, because I'm not sure what you actually want to do, But the search engine is very thorough and the threads are numerous.
Good luck. I'm sure you'll be quite content with your newly rooted/rommed NC.

I have a section in my tips thread linked in my signature that deals with bootable SDs, but I'm not sure it's going to help you. I was helping another user that had the same exact problem where the Nook would not power on with the SD in. One of the things I had him do was fully charge his Nook. I can't remember how he resolved it though, if he did. But I suspect a faulty Nook or SD. Pins bent or something.

Thanks. It's worth noting that, if I get an SD with normal data (photos, etc) on it and put it in while the nook is booted normall, the nook can read the card and see what's on there. So the nook can read cards. That doesn't mean the boot-up bits aren't screwy.... this is refurbished.

Update
Update: I got it to work. However, it's quite laggy, possibly because it's Honeycomb on a class 2 (low IO speed) card. Can anyone point me to a super-slimed android (don't care what version) .img file I can put on my card?

Oh, do not use Honeycomb. It is terrible. Use CM 7.2. They just this weekend came out with a stable version. Cyanogenmod.com. Look for encore stable. And your class 2 should work great.

Let me +1 the latest and greatest CM 7.2. I was using a supposedly faster card with 7.1 on an NC and I also experienced a lot of lagging.
Switching to a class 4 SanDisk card and going to 7.2 fixed the problem. Since I did both at the same time, I can't tell you what exactly made the difference but if installing 7.2 does not fix the issue, try changing your card.
I followed these instructions which installs CM7 on your SD card so you can dual boot if necessary. Also, this has the same exact info written in a slightly less techie language. (I am not sure why he is trying to use the hardware keys to reboot into the recovery mode when it can be done easily from within CM7.)
Good luck!

I know this is a super old thread, but it seems like an appropriate place to post. I've got three Nook Color tablets from my niece and nephews. I flashed them with Mirage Cyanogenmod 7.2 via CWM on an SD card. Once I got the SD setup, I went through two of them in 10 minutes total. No sweat. I installed two fresh, out-of-the-box SD cards in each tablet, which left the modded, CWM SD card untouched after flashing the first two. The third one was missing for several weeks. They just found that one. They dropped off the third tablet along with the modded SD card, which was sealed in a ziplock bag, to me. I installed the card into the third Nook Color, which was untouched after flashing the first two, and the third Nook Color booted right past the SD card and into the stock OS. I've reflashed the same .img file and others, including verygreen's onto this SD card. It simply refuses to boot from the SD. I've tried writing the .img file from WinImage, and WinImage32 through the SD slot on my laptop, an SD card adapter via USB, and through the nook itself as a mass storage drive. I'm stumped. Any thoughts?
On a side note, I don't have access to the first two to confirm the SD card is still on track, nor do I, at this point, have a spare SD card to troubleshoot with. Those are my next steps to take, but I am curious what the experts might have to suggest in the mean time. Thanks in advance, and I'll post my solution, if I solve this.

Are you sure the third one is a Nook Color? It could be a Nook Tablet. They look the same, but the Tablet has a silver bezel instead of black. Those cards will not boot on a Tablet.

My first thought was "that's a ridiculous question. Of course it's a Color!", but then I peeled the cover off, and the bezel is indeed silver. Looks like I have some more reading to do. Thanks for saving me a TON of grief and frustration.

Just to follow up, I followed the instructions for flashing Cyanogenmon on the Nook TABLET, thank you Leapinlar, and everything is good. Thanks again.

[Q] Nook not powering on

Hopefully won't get in trouble for making the same topic, but I was told I posted in the wrong section, so...
Anyway, without fully reading or knowing my girlfriends Nook was a color, I tried to downgrade it with the information from the topic '
[Stock Firmware]Restore Barnes & Nobel Nook Tablet 16G 1.4.0 from SDCard'
Like I said, didn't realize she had a color, and it's a 8GB, rather than 16GB.
Now the problem is that it charges but it won't turn on, at all.
I've been searching off and on today looking for ways to fix it but even when I find something links to things I need are dead. Can someone tell me exactly how to fix the Nook so that it can power on, link to me working links of what will fix it? I've hacked my Wii, PSP, so I'm not completely new to rooting.
I was also told I should make a bootable CWM card flash a CM7 ROM, but I'm not quite sure what that means... so if someone could explain?
Much appreciated, thanks.

Leapinjar knows a lot of about the Color and has made a very extensive post about it here:
http://forum.xda-developers.com/showthread.php?t=1621301
I would start with item A10 on that list

It won't turn on because the boot files are corrupted. As the prior user said go to my tips thread and make a bootable CWM SD per item A10 and then flash the stock ROM from A15.

I still can't get anything to work. I'm using a 8GB micro sd card.
I burned the CWM Recovery SD v5.5.0.4 to the sd card using win32 disk imager. I had to expand it, which I used the mini tool like you said too.
I downloaded the stock version 1.4.3 zip and moved it to the sd card. Tried to turn the nook on but nothing.

And you are sure it is charged? Put my card in and plug the device into the PC via the charge cable. Let it sit there for quite a while and see if you get any life.

As far as I know it is. The light is green on the cable, and it was fully charged before I messed it up.

Cm 10 on sd card

Guys
I have downloaded various times the files needed to burn cm10 on an sd card and tried on 32gb and 2gb cards
and nothing works Now I am downloading everything again from Leapinlar how to links see if that makes any difference, is there a step by step I can check to see if I missed something I actually have A 8gb card with cm7 which I did and it runs flawlessly would like to build a 32gb with cm 10 any help guidance or advice will be highly appreciated must bare in mind you are dealing with a grandfather with not many haircuts left
thanks guys

When you say it does not work, you need to be more specific. You mean you put it in the slot and try to boot and it boots to internal memory? Or something else. Tell us more.
And you say a step by step. Not sure how many more steps you need than what I have in my instructions thread.

Two questions.
One, are you sure you have a Nook Color rather than a Nook Tablet? The Nook Tablet has a silver bezel. The Nook Color bezel is black. My card will not work on the Tablet.
Two, are you following my advice about how to burn the card. Namely, are you using an external card reader to hold the card? And are you running the Win32diskimager program in administrator mode?

[Q] Unable to boot my Nook Color 1.4.3 using MicroSD.

Greetings! I have a Nook Color v1.4.3 and I have tried to boot it on Sandisk class4 16GB MicroSD. I tried a bunch of different bootable images as well as writing the image with Winimage and Win32diskimager. I spent most of the day yesterday trying to get it to boot and it continues to boot up on the internal image rather than the MicroSD. Are there versions of the Nook Color that has the MicroSD card slot boot feature disabled? Any help would be greatly appreciated. Thank you!

Need more information
What are the specific steps you went through to write the images? Which images are you using? It's a Color and not a Tablet (dark grey vs light grey bezel common mix-up)?

The bezel is dark grey. I have tried writing several boot images to my SDCard using WinImage and Win32diskimager. The images I have tried are CWM-6.0.1.2-bootable_SD, TWRP-2.1.8-bootable-SD-encore, generic-sdcard-v1.3-CM7-9-10-larger-Rev5, generic-sdcard-v1.3-CM7-9-10-10.1-larger-Rev6 and generic-sdcard-v1.3-CM7-9-10-10.1-10.2-larger-Rev7. The model number is BNTV250.

Having tried to make those SDs boot you have obviously been to my Tips thread. Did you try some of the techniques in my section A9 there? Like using an external card reader, etc? And the colors of the bezel are black for Nook Color and silver for Nook Tablet. None of those images will boot on a Nook Tablet.
And there a no versions of the Nook Color where SD booting has been disabled.

Yep. Definitely a Nook Tablet. Get to that section of the forum and I bet you have all kinds of success.

Thank you all so very much for your help. I did have much success once I was pointed in the right direction. It turned out I did in fact have the tablet and not the color and was able to install the lastest CM.

[Q] My Nook color keeps booting to the B&N "n" screen and I've tried it all!!
Hi all,
I've been trying to flash my nook color which had been updated to 1.4.3. I wiped it and also powered it down 8 times until it restored to factory settings.
I bought a new Sandisk class 4 8gb microsd card and I'm using an external Targus USB card writer.
I then run Win32DiskImager as administrator and write Verygreen's size-agnostic SD image to my SD card. I eject my card writer temporarily and then reinsert it. Then I copy cm-10.1.3-RC2-encore.zip & gapps-jb-20130812-signed.zip on to my SD card.
Finally I insert the SD card into my nook color and turn it off but it starts with the B&N "n" screen. I have tried different clockworkmods and TWRP mods as well as auto-nooter-2.12.25.img and manualnooter-5.08.20.basic but my nook keeps loading to the B&N "n" screen.
I'm really frustrated and don't know what I'm doing wrong.
Do I have the only Nook color that can't be flashed? Please help!!!

He had you look at the model number to see if you really have a Nook Color. You don't. You have a Nook Tablet. It is a common error. Nook Color files will not work on a Nook Tablet. You must go to the Nook Tablet forum to get the files and instructions.
