I am prepping to move my CM7 install from SD to EMMC and had some questions for you gurus out there:
1. Is it possible to dual boot stock unrooted 1.2 and CM7 on EMMC? I would like the freedom to be able to install CM7 nightlies without having to wait for custom-prepped dual boot roms, so it's not 100% necessary if that's not possible. Is it relatively easy to revert back to single-boot stock? (Is it just a question of resizing partitions and removing CWR?)
2. If #1 isn't possible, do I need to de-register my NC before installing CM7 to replace stock? I had read somewhere about an issue of nooks not being de-registered before doing something then people unable to re-use stock back. Vague, I know. 2. NM, I believe it was regarding rooting stock prior to registering with B&N. Someone correct me if I'm wrong.
3. Is the performance difference worth it to even install CM7 to emmc vs using it off SD? Currently using a decent 4k-write etc. Sandisk 16GB class 4 uSD.
4. Any issues/problems with running CM7 off EMMC vs SD (besides the obvious voiding warranty, etc.) The only thing I could think of would be if I accidentally damaged the NC by dropping it (or it just dying randomly) and being unable to restore to stock to avail of my extended warranty with Best Buy.
Thanks for any help, I'm loving the Nook Color.
I can answer #1, as I am doing exactly that. I followed this walkthrough:
http://www.mobileunderground.info/showthread.php?t=51217&p=84794
and it came out perfect. Puts CM7 as the main boot and stock 1.2 and the secondary boot partition. Now I can update the nightlies without a hitch. No need to worry about a special dual boot zip because the stock is in the secondary partition and isnt affected when doing the flashing the normal way.
Answer to
no 3. YES installing CM7 is a huge boost on mine
no 4 I think if you have hardware failure (ie. dropping it) and you cant turn it on, best buy wont be able to do it as well. They just replaced you with a new one. It happens to me they replace my nook with a new one the same day (I rooted and load froyo on my old nook)
Took the plunge 10 mins ago, and man my uSD card was no slacker but it's like a whole new machine! Thanks for answering --- decided to not bother dual booting, bluefire ereader is coming out sometime next month for android and that should fix my reading needs then, for now I'll live with terrible nook app (I don't read mags or kids' books anyhoo)
If you aren't dual-booting, what did you do?
I'm considering the same thing, I've got CM7 on the emmc but I haven't moved over the app data; does just copying /data work?
I've spent about 20 hours total trying to unbrick my nook color.
It started when I was (happily) running CM7, but I wanted to have HC preview 4 to use at times, so I decided to dual boot it. I went in to dual boot it, and it had an error. So I flashed the remove dual boot zip to reset it, then I went looking for an answer. I find that it looks like my media partition somehow got corrupt, so I go into ADB to see if I can get that working. From within adb I run "adb reboot recovery", and then it never turned on. Freaking out, I searched for an answer. I got it booting into CWM on SD, and Nookie Froyo SD. I've tried all the unbricking methods, even the advanced one that requires DDing boot.img and system.img. I got into adb from recovery and found that my partition table - I had none. So I find out how to fix that, and I do. Fixed it properly infact, looked exactly like it should. So then I go and DD boot.img and system.img, remove the SD, unplug from power, and try to boot into recovery, no luck. Tried a normal boot, no luck. I've done this multiple times. I think it has something to do with the boot partition, I verified it had contained the proper files(u-boot.bin, uImage, etc.), it was marked as bootable, but it wasn't booting.
I held down the power button for 25 minutes just to confirm without a doubt it wasn't(I watched a show while waiting, unfortunately it was my figure holding it down, not tape).
Nothing I tried fixed it.
I think I may have been one of the first to "actually" brick my nook.
Any tips on what I can do to try to unbrick it? Ask me questions, have me acquire data, I don't care.
I have access to adb in recovery, and adb connected wirelessly via nookie froyo sd bootable(for some reason it won't let me use adb via usb).
I apologize if this is in the wrong section.
Also, before you go saying that this is pretty much a repost of other threads, I looked at multiple threads with people trying to fix their nook, threads with 60 pages, read all of them. No one had a problem like mine.
If you are willing to put CM7 on the internal memory, follow the instructions here: http://mrm3.net/nook-color-how-to-install-cyanogenmod-nightlies/
Make your you use the latest version of CWR (v3.2.0.1) Once you have everything working properly, reformat the card to use as storage. Better, keep it as is in case you ever have to preform a new installation and buy a new card for storage. You will need one to properly use CM7 to full advantage.

I was hoping doing what you said would work - but it didn't.
I follow this guide(http://mrm3.net/nook-color-how-to-blue-dot-nook-color/) to get the partitions reformatted properly then installed it.
Glad the site still was able to help you with your issue....
It didn't help. I already followed that guide. Their is one like it here.

No, I just didn't have to found the one on xda because there was one on that site. No need to fight.

Since you said "trying to unbrick" then why not try to reverse back to the original state before installing/running any other ROMs

Go to my youtube page.
Download my ROM by clicking more on my description.
Extract and burn to a SD card with WinImage or something.
Seems like you need to fix your boot partition. Hold the power button down for 15 seconds with no USB plug in the nook. Put your recovery SD in the nook and hold power for 5 seconds you should boot to the SD card. Flash the “repartition-boot_emmc-800mhz-stock.zip” if you want the 800 MHz stock kernel and reboot the nook. If you want the 1.1 GHz Kernel flashed then use “repartition-boot_emmc-1.1ghz-froyo_setboot.zip”.
Once you flash that go ahead and flash my rom just for ****s and giggles to see if you can boot into it. Enjoy. Let me know if I helped.
If this doesnt work you can always DD your way to a new partition. Example below but lets do what I put up top first.
dd if=/dev/block/mmcblk0p1 of=/sdcard/xe.nook.color-froyo-v2.2-boot.img
dd if=/dev/block/mmcblk0p6 of=/sdcard/xe.nook.color-froyo-v2.2-data.img
dd if=/dev/block/mmcblk0p5 of=/sdcard/xe.nook.color-froyo-v2.2-system.img
Well, I'm already processing a return... But if I run across this problem on my new nook, I'll try that.

Return it and try CM7 normally installed to EMMC. Dont **** around with dual boots and all this other crap
When you get your new one in, and if you decide to put CM7 on EMMC, just leave it as CM7 alone.
Shame you sent it back before we could work it out, I was looking forward to trying to fix this - but I can imagine just how frustrated you have been with it and I don't blame you. Probably at the end of your rope and in your place, if I could have gotten B&N to exchange it, I would have too.
Because the Nook Color boots from the SD first, you can always just install whatever else you want to play with to a MicroSD card and run it that way.
Verygreens sd card prep thread is a fantastic first step in this regard. (click "SD Install" in my sig to get to it)
I personally still have my Nook Color stock on EMMC (with B&N official updates) and run my CM7 and other installs from the sdcard. Just make sure it is a SanDisk card and you'll be good to go. (also links in my sig to find out why SanDisk if you're curious)
The benefit to running from the sd-install, especially on possibly unstable ROMS, is that if it doesn't work you simply remove the card to get your device back - instead of having to run recovery on your device.
The latest stable release of CM7 is absolutely fantastic on the Nook Color, and i'd highly recommend it as your daily driver.

I wanted something on the emmc, and my microsd card is to slow to consider booting from it. I'll probably get a better one or just use my current one, and install honeycomb on that.

I had CM7 as my normal install, I just wanted to try honeycomb and my sd card was to slow to consider booting from it.
There's an image around these forums somewhere that lets you dual-boot Phiremod and HC preview on the SD (you just flash it to the SD and go).
It's always safer to play with SD new boots, since you won't hurt your EMMC installs.
With that really said -- the HC previews on the NC are ... not really worth playing. There's no hardware acceleration - so that are abysmally slow. Really bad. You'll try swiping the home screen and go "ugh, back to CM7".
Quite honestly, there's nothing better for us than CM7 on SD or EMMC. Phiremod is just candycoating on CM7 anyhow - and nobody's ever come up with a ROM for us that isn't just fiddling around with a base CM7 or a themed layer on top of it.
What we get from our CM7-Encore installs is pretty much what we want. Theme it all you like - but in reality, nothing else beats it.
youre in luck...my Bricked nook is not getting returned...
i have a bricked nook ...had cm7 on it for 1 1/2 years ..thought i would put cm10.1 on ...to emmc... everything went well installed cm10.1 then gapps ...forgot to install cwm or twrp...oops ...been bricked ever since ..tried pulling battery ..left it disconnected 8 hours ..plugged battery back ...still unresponsive ...tried tips section from leapinlar to no avail ..tried 8 boot method nada!!...never even see a backlight flash ..battery shows 5volts so its not dead...any help ?? anyone??...thanks

And bootable SDs do not work? It will not even turn the screen on unless there are valid boot files in the boot partition or on a bootable SD.

...what are your thoughts on making the sd cards with my linux(mint 14) laptop ...am I grasping for straws??
Hi all,
After using stock for a bit, I realized I will never, ever need it. I've currently got the SD dual-boot going from ikingblack's instructions and have a CWM backup from my stock install, so if I need to go back I can.
How could I remove dual-boot and go CM7 only?
PS Also, I ALWAYS boot into CWM with the SD card inserted. Not holding any buttons. Did I miss a step?
I'm wondering same thing. Been running dual boot with cm7 on 16 gig card for a week and found I like cm7 better then stock. Will it work if I make a CWM nandroid, flash just clockwork to emmc with a spare 8 gig card then install my 16 gig card with cm7 on it and boot into recovery and restore backup? Seems the easiest way without setting everything up again but not sure if it will work. Also never flashed recovery yet from rom manager, should I do that first? Appreciate any help.
Two options pop up in my head.
1. According to many members, Titanium Backup will save your work (apps and settings) or
2. Re-fresh installing CM7 on the uSD card.
I had made a dual boot sd card running Cyanogenmod 7.1 but when my nook started giving the message that xx has stopped responding. I tried to modify my SD to upgrade to Cyanogenmod 7.2. Unfortunately I ended up flashing CM 7.2 to the emmc and lost the stock nook app. I can't figure out how to get to a recovery menu to flash a stock nook rom back to the machine so I can start back with a dual boot sd card. Any help is much appreciated. Unfortunately, I knew just enough about rooting to be dangerous.

Easiest way get stock back is to flash it with a CWM bootable card. See my tips thread linked in my signature and look at item A15.
