[Q] Nook Color Rooting Issue. - Nook Color Q&A, Help & Troubleshooting

New here, yes I did look around. Found lots of other good info, but not this. If I missed it, feel free to remove my man card. I just got a nook color for x-mas yay me. I have followed two guides:
Well I tried to post two links but that wont work. I understand. Anyway, one guide is called How to Install CyanogenMod 7 on the Nook Color (PC Version), found it on Youtube. Other is called How to: Root a Nook Color, install CyanogenMod 7, and overclock it off of icrontic.com Hope that helps.
I am using at 8gb version to write to SD card. I copy both files over without un-ziping them. Follow all directions. However nook will not boot into Cyanogen. I just get the normal nook boot up. I have tried several times. I am new to the whole rooting thing and have seen people post different versions of the same file. Not sure if that has anything to do with it.
Lastly,
Nook firmware: 1.3
Not using a Scan Disk SD card.

I assume you want to enjoy the beauty of CM7.
Before guiding you, a very first basic question needs to be asked: do you want/intend to run CM7 on eMMC or off the uSD?

I assume you want to enjoy the beauty of CM7.
Before guiding you, a very first basic question needs to be asked: do you want/intend to run CM7 on eMMC or off the uSD?
Well I didn't know there were other options other than CM7. I have also been told that is one is the best all around one out there. You will have to excuse my ignorance but what is eMMC and uSD?

Don't worry, we all learn something day to day.
CM7 is a custom ROM (or OS if you want to call it), which replaced the stock OS by many of us. It is one of the most used ROM out there for NC (short cut for NOOKcolor)
In order to run/use CM7 on the NC, there are 2 choices:
1. Installing and running it (CM7) from the internal memory (a.k.a. eMMC) or
2. Booting and running it (CM7) from the external uSD card
You can spend the whole day searching for the difference in details, here, I just give you some quick thinking of the 2.
Running from eMMC = more complicate installation process, smooth performance, a lot less FC's (Force Close = applications hung), easy to backup, more storage. But you will void the B&N warranty since you delete their original stock OS.
Booting off uSD is a quick way to explore the beauty of CM7 or any custom ROM WITHOUT effecting the stock OS, meaning still under warranty. Down side is you need to have a 8GB or 16GB Sandisk class 4, which probably costs about $20 (onsale for 16GB).

Ok does it have to be a Scandisk sd card? I thought loading CM7 via SD card removed the warranty also. A side question I have. I saw on youtube someone was able to "dual boot" the nook OS with the CM7 OS. They could swap back and forth, any idea what this is about? Sorry I don't have much more information on it than that.
If loading through SD card does not void warranty I would prefer that for the time being until I get the hang of this stuff more. Then again a fully rooted nook is basically a android tablet+nook. The only reason I would want the warranty is if something inside were to break.
Would the reason why my attempt didn't work be related to the fact that I didn't have a Scandisk SD card?

No, it does not have to be a Sandisk but Sandisk (class 4) is the best (have been tested) on the market. You can use any other brands, it might work and might not. Therefore, if you intend to run CM7 off uSD, Sandisk is strongly RECOMMENDED. If you use the uSD as an additional storage, any brand is OK.

No, it does not. Running off uSD has zero effect on stock OS.

A lot of people mistype or mis-use the term "dual-boot"
AFAIK, there is 2 kinds of "dual-boot" (one of them is incorrectedly used)
a. Leaving stock OS on eMMC and booting CM7 off uSD.
b. Installing 2 different ROMs on eMMC.
I personally choose to say b. should be called "dual-boot", not a. but a lot of people calling a. as "dual-boot". I don't mind.
What your question is for item a.
All you have to do is during powering up, press and hold the "N" button then select booting Normal, it will boot into whatever on the eMMC (i.e. stock OS) even having CM7 uSD plugged in.
If loading through SD card does not void warranty I would prefer that for the time being until I get the hang of this stuff more. Then again a fully rooted nook is basically a android tablet+nook. The only reason I would want the warranty is if something inside were to break.

A very good choice. Go for it.
Note: recommend getting the Sandisk class 4.

I don't know what you're doing so can't say.
What have you done?

Ok sorry it took me a little bit to get back to you guys. I work the night shift so it can be a pain and make you seem like a ghost.
So I downloaded a file called 8gb_clockwork-0.7. Used a program called Win32 Diskmanager to write that file to the SD card. I have an 8gb SD card. Not Scandisk.
I then copied over two file that are .zip files. I did not un-zip them. Files are gapps-gb-20110307-signed and update-cm-7.0.3-encore-signed.
I am using my phone as a micro SD card reader. Could that be causing issues?
Everything I read said to do what I just said/did. I then pop in the SD card into the nook. My nook then boots up normally, I.E. standard nook OS.
Any help would be greatly appreciated, thank you.

Again, it goes back to my question in post #2.
Before getting an answer from you, I cannot provide any more help.
In fact, I don't want to guide you through the wrong direction.

I would like to run it off of the USB drive until I get familiar with it. Just in case I do not like it. As this is my first time rooting something I would like to keep my options open.

I assume you meant to run CM7 off uSD (you said USB drive???)
Anyway, if that's the case, what you have done was incorrect.
Forget about it, start over again.
With your not Sandisk uSD card, I wouldn't recommend but if you have to use it, then go with it for now.
1. download "win32diskimager" (I hope you already it)
2. download the "Size-agnostic SD" v1.3 imager from this link: http://forum.xda-developers.com/showthread.php?t=1000957
3. try this ROM (build 12122011) as many others like it from this link: http://forum.xda-developers.com/showthread.php?t=1344873
4. download this GApp (20110828) for CM7 from this link: http://wiki.cyanogenmod.com/index.php?title=Latest_Version
5. try to follow verygreen's instructions from the link that I posted in step 2.
If you not able to or hitting issue, get back here for more help

Will do. Thanks again for all the help. Also yes I did mean uSD :/ I will try this Wednesday during the day and get back to you as I am about to start another shift.

A Couple of Questions Please if I May :D

First of all, really big KUDOS MUCHACHOS to the CM7 Dev guys! I had already donated a pretty hefty amount due to using CM7 so much on my Evo but I donated again cuz this is awesome! I do have a couple of questions tho, which I can't fine answers to. I did search for them but really had no luck. The NC community is not yet as organized as the EVO one, I am getting conflicting information and in general having a really ***** of a time finding anything so sorry if some of this has been answered(Im sure that's likely the case at least for some of them).
I used the size-agnostic SD card thing to make the SD Card i had into a CM7 install. Running the latest stable(as of 2 days ago). But thing of moving it all to internal memory. So here are my questions.
1: If I do this, will I be able to still access the real NC OS that shipped with the device? The Nook for Android app sucks, it won't play several of the books I already got(says they are invalid format when I try to DL them) so it is imperative to me that I keep access to the NC OS i have now(but I wouldn't care if it were on the SD card as long as it worked for reading books).
2: What will CM7 be like if I do this? I am gonna assume it won't take so long to boot anymore? Will it basically be a giant phone? Full access to the SD card? Still able to use the internal memory as storage(I use it to store music now)? Work exactly like my Evo does now? Except that it won't make calls of course.
3: Rooting. It seems that so many people are running CM7 that the guides/walkthroughs on rooting are hard to find. So a simple question or two pls Which method should I use? What, if any, are the drawbacks? I would still run CM7 most of the time but while in NC OS to read or something it would be nice to have access to android market etc as long as it wont effect my install of CM7.
4: CM7 nightlies. Can I run them from the SD card as well? If so can I just flash them right over my current SD card install without losing everything?
5: Can i run the OC Kernal while running CM7 from the SD card or do I have to run on Internal Memory for that to be possible?
Thanks for taking the time to read this pls answer any questions that you can I'd appreciate it so much!

I'll answer what I can.
1: Nope, stock ROM is replaced when you install CM7 to emmc. No way around it.
2: I'll have to defer on this one, I've always run from SD card. BTW, you are running from a class 2 card, right? The "faster" cards have serious issues.
3: My understanding is that you have to use ManualNooter for B&N 1.2. I haven't gotten around to rooting it since I upgraded to 1.2, but it was painless on the earlier ROM. There were no drawbacks, besides the fact that it's not CM7. ;-)
4: Yup, they just flash right over just as long as your following verygreen's instructions.
5: Yup, OC from SD works fine.
I don't know the specs on my SD card, it's whatever came with my EVO. I upgraded to a 32gb on the EVO so I used the old one for the Nook. My Evo is only a couple months old if that helps ya.

[Q] What to install...

I just bought a Nook Color for my girl and wanna root and install a costum Rom...since this is my first time doing this to a nook color (i have done this to my G1,Vibrant and Asus transformer) i wonder what is the most stable Rom?
should i go with Cm7 or Honeycomb?
Keep in mind that i'm looking for stable Rom...i don't want to get my girl mad at me..
Thanks in Advance..
Get a microSD card, and install CM7 onto that. You protect the B&N system, so you won't void the warranty. The entire OS and apps sit on the SD card. The Nook will attempt to boot to the SD card first, so you're golden. Any time you want to be back in the B&N mode - just pull the SD card. No need to root or anything.
Go here for the easy-to-read steps on how to make it happen:
http://quinxy.com/2011/04/01/comple...on-the-nook-color/comment-page-3/#comment-944
Even if you were to mess things up you can always restore the stock rom because it boots from the SD card. That's what's so awesome. I would also agree with cm7. There is a sticky in the apps thread that has a good start on what apps you should download first. Some are paid and some are free. Have fun!
I totally recommend Racks11479's Phiremod/Honeycomb dualboot MicroSD image. It automatically boots into Phiremod (CM7 variant) but also gives you the option to boot into Honeycomb if you want to play with that and an option to boot into stock Nook Color software without taking the MicroSD out. Very nice. Also, if you're worried about stability I highly recommend getting a class 4 Sandisk card to run it off of. If you read through some of the forums this seems to be the best card for running ROMS smoothly. You can find the Phiremod/Honeycomb image here: http://forum.xda-developers.com/showthread.php?t=1045018
Good luck!
And first thing make sure you have a SanDsik microSD card.
It can be a 4/8/16 gb class 2/4 card.
There are a lot of nookers who start out with the wrong card and have a lot of problems later on, not to mention waste of money for those high class cards.
Again good luck.
Echo everything that's been said in this thread.
You have all the right answers posted to get your feet wet without worry.
If you don't want to use the (more experimental) honeycomb on the sd install, just ignore it when you boot it and it goes to the more stable phiremod version of CM7 by default.
The memory card advice is no joke. If you get a whole mess of force-close issues running the rom recommended above from an sd install, it's either a bad download, bad flash, or (90% likely) you need the right memory card.
My sig has the link to the thread if you want to know why SanDisk.

[Q] new and don't know where to start

Ok My wife bought me a nook color and I'd like to make it into a tablet. I found a video on youtube that has it running cm7 on a micro SD card but then then runs the stock NC software so as to not void the warranty.
I've tried reading the nook devs, and multiple how to's but feel a bit lost. Can someone point me to
1) step by step instructions even an idiot can follow
2) a link to the different mods and how they are different
3) where these mods are found.
I'd like a way to do this using free software. One place i found to just buy the mod on an SD card and just install it. One other place gave some instruction but needed software that had to be bought (unzippers or something along that line).
thanks for any information I'm feeling a bit overwhelmed..

I started my NC journey by reading some good, but outdated, guide on how to do root and flash custom ROM to the NC. It took me some time to find the correct program to use.
manualnooter: http://forum.xda-developers.com/showthread.php?t=1054027
This post has a rather detailed instruction. Note that you will be installing a custom ROM onto NC and will void warranty... but you can also flash the stock ROM back to the NC in case you need to use that warranty so you don't really lose much.
I forgot which ROM the manualnooter procedure would install, but I think the current most popular and stable ROM is cyanogenmod 7.
Unfortunately the entire procedure will take beginners more than 10 hours to have a grasp on how to do things and maybe poking around and see why some things work that way.
Welcome!
I've personally installed CM7 to emmc (internal memory) using these steps:
http://forum.xda-developers.com/showpost.php?p=11452450&postcount=19
I was also using the microSD card method, and the steps below are good to follow:
http://forum.xda-developers.com/showthread.php?t=1000957
I would recommend using the latest nightly vs a labeled "stable" release. The nightlies have a lot of improvements and are in fact very stable these days. The only thing you'll need is a microSD card, a card reader, and a little bit of patience. It's really not hard, but just make sure to follow all of the steps. If you have any more questions, feel free to ask or search previous threads
I was considering a nightly build.. the nightly builds I need to find the encore build right? (wonder why we call these units encore). Secondly I was wondering if theres an option out there that allows a plain version of gingerbread without the cm7 markation all over the place. Is there functionality in the CM7 builds that I wouldn't get with a pure gingerbread build?
Yeah - encore is the codename for the Nook Color. I think it came from the initials NC....encore. You can always find them at
http://download.cyanogenmod.com/?device=encore
I'm actually not sure if there is a pure gingerbread rom out there. CM7 is based on the official release of GB, and adds some nice things for the nook -- one big one is the honeycomb style soft keys at the bottom since the NC doesn't have the normal android hardware keys.
For newbie, I strongly recommend installing and running CM7 off the uSD first.
Play with it for a while, get used to it, familiar with it while spending more time reading threads/posts in here then thinking about switching it to eMMC or rooted NC later.
Installing and running off uSD are much more simple and easier.
The requirement is: a good (SanDisk class 4 reported as very good) uSD, 8GB or 16GB.
Then follow this: http://forum.xda-developers.com/showthread.php?t=1000957
Cyanogen has this quirky little tradition of naming the software release after the original code name of the device. The Nook Color was code named "Project Encore" (http://www.droiddog.com/android-blog/2010/10/nook-color-likely-dropping-this-week-image-leaked/) by the developers, so the NC is the Encore in CM7. (Similarly, my old Motorola Cliq is called "Morrison" and my T-Mobile G2 is called "Vision")
And Stock Gingerbread doesn't have a number of things which are very useful for Tablets, such as the taskbar "soft buttons" for back, search, home, and menu, as well as the ability to put the taskbar on the bottom, and adjust the lock screen as you see fit. CM7 has all of these, plus the ever popular "much, much more!" The CM7 developers and mods have really outdone themselves and made the Nook Color a massively useful device.

+1 This.
Follow the instructions in that link and you should have a working microSD CM7 installation. 3 things to add to those instructions though:
1.) Try using Win32DiskImager instead of WinImage. People have had problems writing the image with WinImage. The only problem I've seen reported with Win32DiskImager is that sometimes you cannot create a good usable image of a disk greater than 4GB.
2.) If you are looking for a good usable card, get this one. It includes a good USB microSD reader to use when writing the image.
3.) This one is optional. The default SD card image writes an approximately 120MB boot partition to the microSD. With the latest nightly releases of CM7 you can run into issues if you are trying to install both CM7 and gapps at the same time. It is recommended to resize the initial partition upwards in size. Some folks put it over a GB but in my mind a few hundred MB should be fine. The most popular tool to do this with is EASUS Partition Master. I haven't personally done this since it is something that has to be done before the initial install and I had mine up and running before running into this problem.

oI bought a microSD from merit line. Its an ADATA BRAND 16GB CLASS 10. it had good reviews and some places I read to stay with above a class 6 or better. I hope this doesn't cause a problem or my wife will be upset... LOL
I was watching a video on youtube about this process and they mentioned not having all the memory on the microSD available due to the partitions. they used the same partition manager to maximize the storage on the card. Will this be needed or does something happen automatically to use make all the uSD card usable?
With that brand, with that speed, keep all of your fingers crossed and prayed.
And after few weeks of enjoy the CM7, if you start seeing weird things, you then can start blaming the uSD.
does it matter what version software i start with? I've been reading around and see everything from making sure that your on 1.0.1 to 1.3? I'm lost?
Also since I'm wanting to do this all on the MicroSD then this may not be an issue but I've heard some say also to log on first and make sure I sign in with barnes and noble before doing anything. is that important or not?
Lastly. does rooting or anything leave a permanent record in turn voiding warranty or can it be taken back so the factory doesn't know.
Rooting does not leave any records. All you need is to return to factory stock before sending in for warranty
ok I've tried the version 1.3 over and over and each time I get the same problem. after reboot it comes to the blue android on a skateboard it it just keeps running in circles. it will go black occasionally but then right back to the android on the skate board.. what might I have done wrong?

Lets test that card and make sure it's gonna work. Go here and get Crystal Disk Mark. Install it and plug your microSD card into your computer. Run the default tests and post them here. We're looking for the 4k read/write speeds in particular. If they aren't around 1.0 then you're likely to have a problem running CM7 off the card.
My suspicion is that since its a Class 10 card it's optimized for large block writes and not small block writes. Card manufacturers will trade off small block write speed to get the higher class ratings instead of going for overall speed. SanDisk seems to be the exception to this in that they do not tweak their cards to get the high speeds which why they're the recommended card for SD install of CM7.

[Q] better way than booting from sd?

ok guys, noob here ive got my nook running cm7 off the sd card itself but its super laggy, and i cant stand it is there a better way to root it so i dont have to use the sd card and which method has the best success?

any others???
this pny class 4 8 gig card is the only one i have im down to re root the whole thing if that is what it takes... i just wanna have something that works half way decent
I've had bad luck with the PNY cards.. Sandisk made it run really well.. amazing difference..
ok cool ill find one somewhere

But the question now is, do you want to upset your stock OS or not?
Or is there a new way to install CM7 on your eMMC without interupting the stock OS?
My NC is still under warranty so I don't want to take the stock OS off yet, although I am very tempted to trade places, putting my stock OS on the SD card and CM7 (as I use it so much more) on the eMMC.
If you don't want to touch the stock OS yet, the sandisk is optimal for these units.
In fact, if you will dig around in posts about SD cards and CM on AD cards, you will find opinions and actual performance tests showing that CM from an SD card can be as fast as CM from eMMC... if you use the correct card.. which is a Sandisk class 2 or 4 of any size.. 2gb and up.
Don't ask me to point you to the posts.. I can't. I only remember reading these things when I was doing similar research.
For $10-20 you can give it a try and do something else if you are not happy.
.. or if you are sure you don't need easy access to stock, go for an eMMC install..
Neither solution is irreversible..
There's nothing the stock Nook can do that Android can't and there's probably a list somewhere of the things Android can do that the stock NC ROM can't but it probably wouldn't fit in this post. Search for 8+1, you can always fall back to "so clean the video wants to play".

Thats not an issue as you can always restore to stock if there is a problem. That is Part of the greatness of SD boot priority. You can restore no matter how screwed up your internal memory is.

The warranty is not really an issue as I found when I had to have mine replaced. You just restore it so stock. When you create your install image SD card save it in case you have to return your Nook. If that happens, just place the stock ROM .zip on the card and boot from it and wipe everything like you were installing CM7 all over again but instead just flash the stock ROM. It can be found here: http://www.multiupload.com/BW8FIEJ2GH (With thanks to Taosaur.)
ok so now ive got the sandisk card in it it benchmarked 1888 i was way supprised but now it doesnt show up on my computer when i connect the nook via usb i want to still put books on it but it wont boot if i put the books directly on the sd card itself

I didn't follow all posts from the beginning so I just make assumption that you're booting CM7 off the Sandisk uSD.
No personal stuff should be placed in the boot partition. Place them in the left-over (/media) storage.
Just install it on the internal memory there are many great Tutorials on it.

If you don't want to touch the stock OS yet, the sandisk is optimal for these units.

I can tell you that I have been running CM7 with nightlies off the uSD card since I got it (3/11). Using an 8gb Sandisk is indistinguishable in speed from the stock system, but SUBSTANTIALLY more useful. Since my NC is still under warranty, all I have to do to "restore" it to stock is take out the uSD card. I love it, and it doesn't take you into the "restore to stock" mess that, while it works fine, is still pretty stressful.
Try a good Sandisk uSD; you probably won't need or want to flash your internal memory.

[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.
