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.

[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?
I used the installer in verygreens 1.3 posts and cm_encore_full-209 nightly build

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] NOOK COLOR Rooting......

I have a brand new Nook Color the Software Version (in about my Nook) says 1.2.0. what is the easyest way to go about rooting? is there a specific version of CM7 that I should use? What is the best rooting method or system to use? I am totally new to all this so some step by step instructions or detailed informatio would be great!!! Thanks for all you guys help!!!

There are several decisions you need to make before you start. Do you want to have dual boot (meaning that you can switch between stock rom and another rom of your choosing? In these case you would be running the non stock rom from the sd card. Or, do you want to go full non stock rom (emmc)? There are different methods for each.
After you decide this, you need to decide which custom rom you would like. The most used are CM7, phiremod and MIUI. CM7 is the most update one and has a lot of following and development.
If like you mention on your post you are looking at using cm7, then I suggest you start with the latest stable version 7.1 (which was released a couple of days ago). You can find the files and instructions in this post and the detail instructions here
Hopefully this can help you, you could also look around in the android development section in the forums for further info and/or wait for more detailed info from more experienced rooter than me

Thanks for the Advise/ information, so if I go dual is it very complicated to switch from one to the other? is there an advantage to being able to switch back and forth? I currently have a 2gb sd card that should be big enough right? Once again thnks for the help..........
Does anyone else have input or feedback???

Just last week I installed CM7 on an SD card in my Nook Color. It's been great so far. I figure I'll try it on the SD card for a while before I do anything more permanent like installing to the internal memory.
When you install to the SD card, you boot back into the "stock" OS by just removing the card.
As for the size of your SD card, I think 2GB is large enough, but that depends on how many apps, etc. you plan to have on it.

I would not recommend doing that. The Nook card slot is a little fragile and excessive swapping will likely damage it. Mine gave out and I rarely remove the card as I have CM7 on the eMMC and only use the card for backups and upgrades. I had a hell of a time restoring the stock ROM so I could return it under warranty. If you are going to run from the card, set it up for dual boot so that you just pick which ROM you want to use when you boot up.

[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.
