Im not new to loading ROM's for Android devices. I have an HD2 and have loaded about 50 ROMS on it in the last year I have had it! Recently, I got my wife a NC, and want to play around a little bit.
The big issue is this. My wife HATES my HD2 simply because every time she picks it up, its a new ROM! She really LOVES the NC, so there is no way she is going to let me really mod the thing like my phone.
There are a few small issues with the stock ROM, and I have been reading the post's for a few weeks now to see if there is something that fits what im looking for, but there are so many post's its really hard to dig even using the search! So please bare with me for asking questions im sure have been asked many many times.
#1, is there a ROM that will still run B&N books? Or will I just have to stick with stock ROM for that?
#2, can the stock rom be overclocked of the above is true? One of the biggest gripes is youtube playback. Will the OC help that?
#3, Has anyone gotten the Netflix player to play on a stock rooted NC?
Basically I want to let her watch Netflix on the NC and punch up the performance a little, and still keep the B&N software useable.
Any help would be great!

1. FroYo and CM7 will run B&N books through the B&N Nook App. Children's books ("Read to me") are stock only (Android 2.1 Eclar).
3. Not sure about stock NC but CM7 works beautifully http://forum.xda-developers.com/showthread.php?p=13737296#post13737296

Actually the latest stock upgrade puts it up to 2.2 - stock 1.1 and below were eclair. The books still work fine after rooting too.

Stock is still Android - the angry birds that b&n sells is Android. But without rooting you can only get whatever b&n sells you.

#1. Also The stock nook color reader app can only be run on a rooted stock device. I am pretty sure no roms at all support it. ( I don't know why there is no froyo rom that is based on the stock build maybe it is not possible) The BN app in the market is a fairly different reading experience.
#2. stock rom can be overclocked just fine, You can find Kernels Here. I run 1.1Gz some times no problems, 1.2 was too much for my device. Usually though I leave the clock down at 800-900 because the boost is not needed. Also, Youtube works beautifully on my rooted 1.2 right now ( I dont remember if the last time i was watching youtube i was overclocked or not)
#3. I am one of the last people in the universe to not have netflix so can't really try this out.
If CM7 still has sleep issues stock will get better sleep battery life by about 10x so your wife wont have to live next to a power outlet.

For pure stock nook colors, Barnes and Noble has their own app store with just under 150 apps I think. Only a small selection of them are free because no ads are allowed. They do have pulse reader though, which is mine and a lot of peoples favorite news aggregator.
Just Install CM7 to a MicroSD. That way whenever your Wife uses the Nook it's Normal Stock, which she's probably fine with, but when you use the Nook you can Pop the Card in and it'll boot into CM7 instead allowing you to do anything you want. When your Wife wants to use the Nook just turn it off and take out the Card, turn it back on and it'll boot to Stock again.
I recommend this Thread for Installing CM7 to MicroSD:

Ok, here's the deal.
Fiancee got me a NC for my birthday because she read that it can be rooted and made into a formidable tablet. I agree with her and am stoked.
I don't have any dev experience, but I'm very familiar with rooting and flashing ROMs to our EVO 4Gs.
However, after reading through the developmental forum, I'm confused as to what steps I need to follow to turn my NC into a CM7 tablet.
Do I run autonooter? (The B&N store updated my NC to the 1.1.0 software yesterday in-store) Which one? Do I run it first?
After that, how do I flash CM7? Is there a more stable system\ROM\build?
With dealing with SD cards, I know this will be a bit against the grain for me because Rooting\Flashing the EVO is so easy and simple.
Any and all help will be appreciated.
(Side note question: Has anyone used a Steinheil Screen Protector on their nook? I see that SGP makes one for the Galaxy Tab, which has similar dimensions as the NC. Anyone?)
This seems like easiest to follow:

Awesome.
So that "roots" the nook, like SimpleRoot does to my EVO?
And then I go through the process in the CM7 Phiremod post in the Dev forum?
Also - should I go buy a second MicroSD card to use, leaving the current one in the nook as a clean backup?
It's useful to have multiple microSD. I have a couple 2GB microSD for nootering and flashing new rom. I use a 16GB for main use as backup and data storage.
If you're new to Android, I recommend just nootering your stock 1.1 NC because it's most stable. Froyo, Honeycomb, and Gingerbread built are still in development and are being tested.

I'm not new to Android, as I've been using various CyanogenMod and MIUI builds on my EVO since I bought it last year.
What I am new to is the use of SD cards for flashing. That's where I'm a bit shaky on the steps.
Before you can get a good answer we need more infromation.
1) do you care about the B&N stuff that your Nook came with?
2) what is your goal?
a) e-reader that can do tablet functions
b) Tablet that can do e-reader functions
Do you want to run the alt OS from the SDcard or from the flash memory?
So far there are 2.1, 2.2, 2.3, and 3.0 ROMS for the Nook. Where do you want to be?

Does the above help at all?
Bump for some help. Thanks guys.
I've only been a NC owner for a week. From my experience, you need to play a bit. Usual disclaimers apply:
1. spend time playing with the default B&N config. Enjoy. Ok, for me that got boring after about 1 hour.
2. Autonooter 3.0 (since you are on 1.1.0). Then just play with your rooted NC. Enjoy. I was amazed at what this little guy could do after only a root. Test a bunch of apps. Read a bunch on this website. Test more apps that you read about. Try different backup software. Get comfortable with Eclair. Run Quadrant. Enjoy.
3. Dahlingren's OC kernel. Make sure you get the Eclair kernel. I installed the 1100 MHz one, and monitored for overheating and random reboots/force closes etc. This one worked well for me, and amazed me again at how much faster it was (run Quadrant again). Get comfortable with the procedure to flash a rom with CWR. Enjoy.
4. CM7 with OC kernel. Play, test, enjoy. If the current bugs are deal breakers, revert back to Eclair, or try Froyo or some other flavour. Enjoy.
It seems to be darn near impossible to brick this guy, so I haven't worried too much. Worst case scenario is I have a $250 paper weight, but the best case has been worth the risk to me.
Enjoy.

If you look at the signatures of most Mods on Nook Color Forums, almost all of them are using Nookie Froyo - probably for the reasons mentioned by the poster just before me.
(In fact, it is rumored than B&N will release an update for the stock NC to Froyo at the end of March, and it will include Flash support.)
Does anyone know if there is still the problem with mounting your sd card in HC after installing internally? the reason i as is because the Nook app its self will not work unless a SD card is inserted and mounted. Making the whole original point to the nook color pointless... lol even though it does make an amazing android tab. with 3.0 it would be INCREDIBLE!!! I had 3.0 installed internally but i switched back to autonooter just because i couldn't read any books because of the sd card mount issue. wasn't sure if they had fixed this in Honeycomb V4 version 2 or not. I would love to know if they have.
If so, we know who will installing it tonight! I got a whoppin 1430 Quadrant score when HC was installed. pretty impressive, better than my Droid Inc. running gingerbread lol

Yeah FroYo if you want Flash and DSP video. Otherwise CM7 since it runs a little smoother than HC as of right now.
i liked honeycomb becuase of the easy way to switch btween stuff but i am enjoying cm7 most cause it runs really nice
Using CM7 on eMMC until HC AOSP comes out and gets a few releases (figuring there will likely be some annoying bugs in the first couple). I liked the HC interface much more, but it was not as responsive and too many apps didn't run properly. My fiancee and lots of other friends/family play Words with Friends constantly as well, and it doesn't work in HC properly, but it does work flawlessly in CM7 from my experience. I'm not a huge fan of the game, but it is one I would much rather not see broken.

Really? words with friends has never worked properly for me... It just does not scale properly on any ROM i've tried... ie the letter tabs are half-off the screen, and refuse to be dragged.
HoneyComb has a far superior UI, but CM7 has far fewer bugs. Eclair was never really stable for me, I've gone to flash Froyo a few times, but the page for the download is really pessimistic and turns me off.
I would really REALLY prefer a stable HoneyComb build. That would be amazing...
the tablet apps are so much better than the default. Plus CM7's notifications pull-down menu really annoys me and should go away. So much wasted screen space...
EDIT: and WHY are the back and menu buttons in the top right? really? pretty much EVERY app has a button right next to them. I try to hit the menu button, and the notification window pulls down. Either that or i push an app button by accident.
I love CM7, and I REALLY appreciate all the work that's been done, but these guys obviously aren't UI guys...
I have had my nook for all of 4 days, but i really like cm7, hc appeared to be too unresponsive for now. I fly a lot and videos are important however moboplayer and or rockplayer between them seem to handle anything i throw at them (divx etc) smoothly. I had an iPad (jailbreak hell) then a g tablet (screen sucks, heavy, cm7 was not nearly as stable as on nook, fast but i don't seem to see much difference browisng/scrolling etc with cm7 experience) and for some reason this nook is by far and away my favorite.
It seems that Honeycomb runs a bit slow on the sd card (haven't tried it running it from eMMC). Right now it seems that Froyo works the best. If they don't come up with a less sluggish HC, I might stick with Froyo.
I may be in the minority but I like the stock rom rooted. Primarily because of the control buttons B&N coded into the task bar, and I don't much care about flash anyway.
I like the Honeycomb UI. I tried the SD version and it's pretty remarkable how well they got that build running. If I were to replace the stock rom it'd be with some version of Honeycomb. Actually I would prefer if B&N just skipped froyo and gingerbread and went straight to Honeycomb for their upgrade (if they are indeed planning an upgrade at all).

what rom you have installed? I had nokie froyo on internal memory and it was reaaally slow. Right now im on 1.1 stock rom and its noticeable much faster.
I prefer Cyanogen. I've read too much about issues with application compatibility with Honeycomb to load it right now. When the developers start pushing out ROMS based on the actual source, I'm sure I'll switch over and try it out.
Right now I have CM7 running with dalingrin's overclocked kernel and this thing FLIES. I'm actually trying to sell my ipad now as I would much prefer to use the nook as my tablet.
I like rooted stock. Was trying nookie froyo in my class 10 sd really smooth. After some customization I will be using NF if I can fix the wifi issue.
Would you recommend me to stay on rooted stock 1.1 (i cant download from the market for some reason) or should i flash nookie froyo on it?
I stayed with rooted 1.1. NF is nice as well, I just like the stock reader app better. Haven't played with HC or CM7, still waiting for them to mature a bit more.
Sent from my rooted stock 1.1 Nook with XDA Premium.
When all else fails, RTFM.
I would make a decision...
Move as far as possible away from the stock experience, or just keep it completely stock.
The whole point in rooting is to give you more options. What's the point in options if you don't explore them? You don't have to agree with them, or keep them, but the idea is to grow with them...

Why must you choose one when you can just dual boot? Dual boot it for a while and see which one you like better.
If you feel like trying something other than stock, I would recommend cyanogenmod, I have been running it for a while now and it keeps getting better.

What are you looking to do?
I started down the path of rooting my NC about three weeks ago, but I knew that would be the case the moment I bought it. However, I also tested out the experience of Froyo and HC by using bootable SDs. It gave me a good feel for what I was missing and what was worse, and then ultimately I jumped aboard the CM7 train.
But without having any requirements from you, it's not like anyone can really recommend an option. Certain features are clearly require newer Android builds (a lot of apps I found needed 2.2 minimum). Squeezing more performance requires certain kernels. Bluetooth from the latest CM7 etc.
i dont want cm7 because of the battery, i want to know if froyo is better then stock.

Not sure what you've experienced or heard, but as long as you have the right settings, the battery lasts a while. I usually charge mine every 3rd day and that's with moderate use. Heavy use is every other day. I get 6-8 hours of active use. What kind of battery life are people getting with froyo?
Dual boot period.

I have rooted and put custom ROMS on several phones, so I am not afraid of the process. I was wondering if perhaps their was any difference between the quality of the ereader (I love the eink technology on my wife's old b&w nook) on stock and the nook app on android.

Nook app for Android is a pain in the everyone-knows. It's shytty.
If you want to read and read alot, stay with ereader.
Oh, and btw, based on what you've described, it doesn't sound like "dual boot"

The only reason I would do this is I want to know if the "reading experience" is better using the stock ereader or if users out there are happy with the "reading experience" using Aldiko or the nook app on a rooted device with CM7 installed.
I find Aldiko to be an equal experience to the full reader on stock - so no need for stock for me. I don't read any magazines, which i think stock may be better for.

I find stock to be pretty worthless, but then the Nook App isn't very good either. I got sick of the stock OS pretty quickly, so I flashed a CM7 Nightly and installed Moon+ Reader for epubs. It's pretty easy to remove the copy protection from B&N epubs. Personally I think Moon+ is far superior to either the stock Nook Color rom or the android Nook app. I even prefer it to the kindle app.

I really like aldiko myself. Love the brightness gesture area on the side and it works great with the library ebook system.
I can't stand stock personally, and the nook app sucks.
To be honest, the rooted stock OS is pretty bad. You'll figure that out for yourself. If you plan on using the NC to read, primarily the magazines because they more or less require the stock OS, then there is no real need for CM7.
Though if you plan on using it as a tablet, which it does very well at this point, Then you probably don't want to dual-boot. My main reason is storage. I know 1gig of system memory seems like a lot. I know I can't be considered the norm, but I only have 110Megs left for app storage. With it cut in half by dual-booting I can foresee storage issues. If you want another reason, in all reality you'll end up just being on the CM7 boot. It's really nice once you have her setup the way you like.
In the end it'll come down to you for the first month or so flashing a lot of different roms / fixing things you break, figuring out what works for you. Don't worry about 'bricking' the NC, it's pretty much unbreakable via flashing roms. If it's able to be screwed up I can guarantee you that there's been a couple threads on it. It only takes a little forum surfing.
Hi,
Im looking for a cheap tablet to gift. After considering the choices, i see nook color fits the bill...
However, i noticed people complaing about some problems like choppy youtube, sleep of death problems, etc with cm7.. I want to know how bad it really is? is it worth buying over regular tablet? Thing is I'm prepared to take a chance, but im gifting it to someone who wont update to latest ROM by himself..so i want to know if cm7 is stable on NC for regular stuff like games browsing, youtube etc...
Also how is the impact of overclocking on battery..is it able to give 6-7 hour runtime on 1.2ghz on interactive governer?

I have absolutly no problems with CM7 on the NC. I have oc'd to 1.1 and can run 9 hours with the screen on. I use it for everything, and would have no problems giving it as a gift to my gf to use as such.
Although, if you are going to give it and never update it, or be there to fix something if anything happens to have, I would buy an android tablet. Not the off name cheepy ones.
If it has to do with funds, I would choose the NC in the end.
It's a good tablet and performs quite nice on cm7. Have it clocked to 1GHz and it stays stable.

It works fine for the most part. Some people do have trouble with sleep but not me. It does have performance problems with Flash video but I think that's due to Flash being very demanding.
YouTube works fine. Netflix does too. Those are my sources of video. Although I use my Nook mostly for web and reading.
The Nook Color is a good cheap tablet with CM7. The best part is the IPS LCD you get for this cheap price.
thanks for the feedback....NC it is then
I forgot to mention that with YouTube you need to run an older version than the one in the market. For some reason the latest version won't play HQ. Just search for YouTube 2.1.6 apk.
Or here is my backup.
Why wouldn't the person you're gifting it to ever update it?
It's pretty simple through Rom Manager, and as long as they just do it like once a week/once every other week to whichever nightly has the most stars in the list... They'd probably be alright.

It seems pretty easy for us...but for a person who isn't technologically savvy or lacks interest in it, its a big deal...Most people are fine as long as it does basic things right and don't care much for new enhancements...
It's entirely possible to never flash again once you have a stable release running. If Android 4 works out on Nook Color maybe that will be worth upgrading too. Otherwise we are pretty much past the teething problems of getting a decent kernel for 2.3, for example. 7.1.0 is a huge improvement over 7.0.3 primarily because of the kernel improvements that arrived since May.
I suggest you explore the stock firmware too. Maybe root it so you can install the market. The stock firmware has official support and you might appreciate that.

Not once you root it. It would have to be restored to unrooted stock if any official support was needed.

Well I have tried using the nook on stock firmware, on B&N itself...but It didn't feel very snappy as other android devices...maybe rooting helps...
But that is why I am interesting in putting cm7 on it before gifting it..
BTW have ordered the nook, its on its way..
Yea there's no doubt that Dalingrin's Nook Color kernel in CM7 is a lot nicer overall than the stock software. That's where most of the speed comes from. Although he used their code, he tweaked it and threw in some enhancements.
If you want the most speed be sure to run 16bit transparency color. You can find that in the CM7 settings under performance. It speeds up scrolling considerably.
