I don't know where to turn. I started a thread about my effed up nook but it got deleted (my fault) I'm completely at my wits end here. I had NookFroyo .68 working just fine on mine but like an IDIOT I thought it would be neat to try out CM7. Big mistake would not get past the animated N screen no matter what. I got the SD version of the Customized Nook Froyo to boot up but its very slow and stuff doesn't work. How do I get a ROM back on the eMMC? Some one suggested I get CWR and a ROM on the card and flash it via CWR off the card onto the eMMC. How exactly do I do this? I CANNOT get the winimage method to work no matter what I do and I don't know WHAT I'm doing wrong. Everytime I direct winimage to the place I've downloaded an image to, theres nothing there....
I thought I ALMOST had it a few minutes ago. I can get the CWR to come up and I flashed the flashable eMMC NF. I got my hopes up as it started to boot BUT OF COURSE NOT - went into a boot loop, constantly doing the N screen over and over. WTF.
I'm desperate here. I'm at the point where I'm willing to pay someone a small fee to help me get this sorted out. I'm going to keep on trying....
on win image, when you go to select the file. you must change the file types it see's to everything. that will let you see the .img file you downloaded.
We are talking about Win32disk imager right? It only gives the *img selection.

I've heard of an 8 boot reset. How does that work?
I'm reading the "Recovery" thread. Should I do the "repartiion" zip file? I'm starting to think that maybe the problem...
EDIT: Tried the Repartion.zip. No change. Still continously reboots.
I just tried the Nook restore file and it still gets hung up on a different N screen (the Nook symbol). What in the HECK! It wont' go into CWR anymore, says there isn't any room on the card. AN 8GB CARD!!!! I put the card back in the computer and it says its only 115MB! WHAT THE HELL IS GOING ON HERE.
EDIT X2: LOOKS LIKE I GOT IT BACK TO STOCK. WHEW! Now I can start over! Tomorrow after I rest a bit. LOL

Hi,
I found this post (in developers/cm7 users thread) very useful for installing
CM7:
http://forum.xda-developers.com/showpost.php?p=11535969&postcount=151
It is a little dated (weeks) but very detailed and should hopefully still all work fine.
Some more general information on:
http://nookdevs.com/Portal:NookColor
I find that I never have enough uSD cards to use - so make sure that
you have several spare. The emmc Androids are still in general expecting
an external SD card for storing data such as ebooks etc. and CWM will
backup to the external cards too.
CM7 and Froyo use different disk format types for various partitions, don't know,
but that may be part of your problem?
Your PC won't normally read some of the linux partitions on the SD card
either - hence only 115MB showing. This is the boot partition, formatted with
FAT32 (a PC related format) In general you don't need to reformat this partition,
just update or change some of the files. (Some of the names of formats used include:
FAT32, EXT3 and EXT4)
CM7/17 and CM7/19 Have both been very stable and easy to use for me. I switched
to CM7 from Froyo 6.8 a week or so ago.
Good luck, the Color Nook is a fun device!

Thanks all I appreciate the help. I used some HP utility to take care of the cards, worked great.
Ok I've got a NF .68 up and running. Titanium backup worked beautifully. SetCPU is running it at 1.1 interactive..... HOWEVER!....
I flashed it with a another version of the CWM flashable .68 NF that I had previously. I tried to reflash the other version and it went to install then stated "Installation aborted". I tried twice and got the same thing. I guess its no big deal since their the same version just this one thats on there had some more tweaks hence the title "Customized".
My question is why did it do that? My guess I was supposed to format or clear the data/system/caches' in CWR. Is that right? If so, which ones precisly do I clear or format before flashing a new ROM? I'm starting to think thats' what happened when I tried to load CM7 (Yes I had CWR 3010) and go me all borked to begin with....
And if someone would like to answer a quick question. What this EXT4 stuff and how does it pertain to flashing ROMs? Thanks guys... Your advice got me back up and running!

Always format /system, /data, and /cache. Whatever you do DO NOT format /boot.
As to why you may have had an issue on trying the other ROM. My guess is it has to do with what version of CWR you had been using and wha twas on the device prior to flashing it. I've found if you make say a nandroid backup using 3.0.0.6 or earlier, and are currently using CWR 3.0.1.0 they don't mix well. And I think it has to do with the fact the older CWR version only supported ext3, and the newer one has ext3 and ext4 support. So once you install a ROM using CWR 3.0.1.0 that uses ext4, and then you try to go back to a ROM that is ext3 it just doens't work out like planned.
That all said I not longer flash CWR to eMMC, and I have a bootable sdcard running 3.0.1.0 with all my current and old backup files. Make life much much easier IMO seeing as you can always boot to an sdcard, and all backups are in the correct format and will Restore just fine.
Thanks for the info! I'm sure that will make trying to upgrade to CM7 actually work! LOL!
But first can someone explain to me what this EXT3/4 stuff is?
Different filesystems for Linux/Android. Wikipedia has pages for each if you want google them and get too much info
Too much info? No thanks! As you can see I can barely handle the info I'm getting now!
All I see are instructions on how to use ADB or to use CWM to flash to the external SD. Is there a way to use CWM ready CM7 for the internal flash?
Hi,
If I understand your question, you would like to run CyanogenMOD7 off the
internal memory also called emmc, rather than running it off the external
memory or uSD card.
Though a bit dated, I found this walk-through to be very detailed:
http://forum.xda-developers.com/showthread.php?t=960542&page=16
Hope this is what you are looking for.

It is helpful, however I am looking for a CWM ready version....so far no luck.
Hi,
The instructions in:
http://forum.xda-developers.com/showthread.php?t=960542&page=16
Are assuming running from uSD version of CWM.
Following other CWM install instructions you can end up with CWM installed
on the internal flash, emmc.
For example:
http://forum.xda-developers.com/showthread.php?t=971197
Minor issue to watch for: the versions of CWM that support EXT4, required
for CM7 also require a different kernel.
I'm not quite sure what you mean by CWM ready version of CM7... the CM7
nightlies are in a .zip file that is flashed by CWM running off the EMMC boot
partition. The first time you install CM7 you also have to use CWM to
reformat some of the partitions on the EMMC (to ext4), but after that you can
use CWM to update the flash each time.
ROMManager can also be used to download ROMS and start CWM.
I am in 'updating' mode, I usually download a recent CM7 nightly and
recent overclock Kernel on PC, then share to Nook using Dropbox.
On Nook, I download .zips from Dropbox and move to root of the data
SD card. I also have latest Google apps (GAPPS) in Dropbox or SD card.
I then use ROMManager to run CWM to backup entire ROM.
Then I use ROMManager to boot into CWM and individually:
Install from .zip: nightlyxxx.zip (Current CM7 version)
Install from .zip GAPPSxxx.zip (Current google apps version)
Install from .zip kernelxxx.zip (Current OC kernel, overwrites the CM7 version)
Then I wipe cache partition.
Then finally wipe dalvik partition - CWM freezes here.
Reboot and wait a while (5 mins) (I assume it is rebuilding dalvik cache here)
Often seem to need another reboot and wait.
Hope this helps...

Thanks, that does clarify things. I'm new at this and do it was a little confusing to me how to do it. In the captivate forum they're a little more forward on how it's done. I appreciate the help. I tried using the rc4 encore signed but it seems to stop at the startup with N color on it. I thought I formatted all the partitions properly. Is there something I did wrong?
Hi,
I haven't had the problem of being stuck at 'N', but I'm sure there are plenty of
others that have... it will be something simple, probably missed one step in install.
Perhaps check through the list you followed and try and remember if you forgot
one step, or didn't understand one of the steps.
My install no longer shows the "N" at all when booting, so I'm guessing that
there is a missing piece somewhere!
I get:
"Touch the Future of Reading"
Brief flash of "Loading"
Few seconds of sideways "android..."
Then an animated CyanogenMOD logo for more seconds.
Here is one (long) thread about booting problems, but there are other ones too.

Got the problem fixed. Had to boot to a different CWM and format as ext4. Now all is well.
Speed Comparison
I have CM7 flashed to a class 4 sd card and it seems a little slow compared to the stock elcair build. Does CM7 installed to the internal memory speed things up a bit or does the system still seem a little slow. I'd like to know before I flash to my internal memory.
It should be faster on the internal, logically speaking, but perhaps with the right SD card you'll get comparable speed.
When I first got my NC, I installed CM7 on an sd card.. quickly found out that it wasnt stable enough for me and I installed CM7 on emmc. I'm selling my nook to a friend and want to return it to stock with no CWM on it.
Before I installed CM7 on emmc I made a backup of my stock setup. Should I restore this backup or wipe everything and use the zip of 1.2 without CWM (this guide: http://forum.xda-developers.com/showthread.php?t=931720)?
I want to return the nook to how it was on the day I bought it when I first took it out of the box. Are there any other steps I have do to unregister it or anything? He wants to be able to purchase books through B&N with it and all that.
Thanks
The 1.2 .zip is probably simplest. It will definitely leave the NC de-registered without any extra steps.
So I guess I'll follow the guide for a clean 1.2 install. I will then be able to update to 1.3 correct?
Edit: Also, my nook is a blue dot, with the newer partitions. If that matters at all.
Hmm, I'm not sure how the 1.2 image will interact with the newer partitions--that thread you linked and the one with the 1.2 image are both pre-blue-dot, with no mention of how the new partitions interact with those methods. Your best bet may be to clear CWM off eMMC and do 8 failed boots, to be safe.
So instead of messing with the 1.2 zip, should I instead restore the clean stock backup that I made using CWM before I installed CM7 on emmc? If I read correctly, I can unregister the nook in the stock nook settings and then re-register it. I think. Basically I want to make take my personal information off of it and put his on.
I guess I don't HAVE to take off CWM, unless it will cause problems? The person I'm giving the nook to is not very computer literate and I don't want him to have any problems down the road.
My thinking is, if you restore from your back up image (presumably made via CWM on eMMC), it will not remove CWM. The 1.2 image from this thread might install just fine as long as your CWM is up to date (3.2.0.1), but I'm not 100% sure of it. Your safest bet may be to repartition first using this thread: http://forum.xda-developers.com/showthread.php?t=1094371
Unless, of course, someone can confirm that the 1.2 image works with blue-dot NCs. If your friend wants the 5GB /data instead of /media, there's another zip in the repartition thread you can use after you're back to stock.
ETA: the main problem CWM would cause is blocking future B&N updates.
ETA2: if you're a gambler, you could just try the 1.2 image (make sure you have CWM 3.2.0.1). If it won't boot, try 8 failed boots to restore. If it still won't boot, you'll need to make a CWM SD card and repartition anyway.
Just rebooted into recovery and my CWM version is 3.2.0.1. CWM has gotta go then, since I want him to be able to receive all future updates.
You could also just google around a little bit, there's a guide to repartition the NC back to pre-bluedot partitions.
It's pretty simple. I did it to mine prior to installing CM7.
Here's a guide: http://mrm3.net/nook-color-how-to-blue-dot-nook-color/
Also, from my understanding the newer partitions shouldn't affect any roms being loaded... including the stock one. They're all made to fit on the original 1gb partition, so they'll fit fine on the 5gb one.
Here's a similar thread to this though. http://forum.xda-developers.com/showthread.php?t=1125675
Success.
Didn't mess with any partitioning. Put the 1.2 zip without CWM on an sd card, booted into recovery, wiped /system and /data, installed the zip, wiped /cache and dalvik cache. Rebooted into stock 1.3 with zero problems. Downloaded the 1.3 update with zero problems. Loving it.
Thanks all!
Are there any other steps I have do to unregister it or anything?

Go to your account on the B&N website and de-register it from there.
I was using the AOSP ICS build posted by jt1134 (at rootzwiki dot com/topic/11697-rom-cdma-aosp-ics-cm9-build101-0418/) for the Galaxy Tab CDMA. The first couple of nightlies worked OK on the tablet, but the camera never worked right. Someone else insisted that the camera works correctly on new builds, so they suggested I use CWM to wipe system, and I took it to mean wipe everything so as to start from scratch, and I wiped /data too. Apparently this triggered the emmc erase bug or something, so now my internal SD is useless.
Nobody over in that thread appears to be willing to make a build that works around the issue. I've already tried partitioning my SD card and editing vold.fstab and updater.rc inside the ROM, but these are apparently useless unless init.rc in the boot image (zimage I guess) is changed. A person attempted that but seems to have gotten the filesystem type wrong in the build (ext2 instead of ext4), and is unwilling to make another attempt. I don't know anything about compiling a custom ROM myself. I've looked into decompressing/recompressing the zimage, but it's too much for me.
What I'm asking here is, can anyone help get a build of ICS to me that I can flash, that will ignore the internal SD and use the external? This site is awash with reports and fixes for Encryption Unsuccessful for other phones and tablets, so I'm hoping somene here can understand my frustration. I haven't been able to use the tablet for over a month now, I think, and I'm not getting anywhere on my own. TIA
Bump
I'm in the same boat after trying the same rom. I gave up on the old Tab, and doubt you'll get any help here. I'm still holding on to it in case Samsung releases a fix, but that might never happen.

Another fellow who had the same thing happen to him posted a guide over on rootzwiki on how to remove the offending chip. After removal you can partition an external SD and fiddle with a ROM and install it. The SD card will need 3 partitions, an ext4 /cache partition (not sure of the size of the regular one, made mine 512MB which I think is overkill), an ext4 /data partition (2GB is the default on these tablets), and the remaining space on the card can be used as the /sdcard partition (FAT). The only thing is I don't think you'll be able to go back to a stock rom ever again. There doesn't seem to be an easy way to change anything in roms that flash in heimdall or odin. CWM recovery based roms can be used, because they're just files in a zip. You have to change a few files referencing the locations of the partitions, including updater.sh and /system/etc/vold.fstab. On my tab the /cache is pointed at /dev/block/mmcblk0p1, the /data at mmcblk0p2 and the /sdcard at mmcblk0p3. I did manage to find a CWM recovery ROM that is based on CM7 GB 2.3.5 that works pretty good, but there are still some bugs with the camera (can't record video on front facing camera). I've resigned myself to sticking with this ROM, since it's otherwise completely stable for me, but I'm still trying to see if there's a way to transplant the working camera software from the verizon stock rom to replace the broken one I have now.

Nook HD not charging since CM11 install
This morning I installed the latest CM11 build (M11) on my daughter's Nook HD. Prior to that I was using the stock ROM with no issues. Since installing the ROM the tablet will not charge; rather than showing an orange light the device shows a green light whenever the charger is connected.
It seems possible that my cable has failed at the same time as performing the install, though a little unlikely.
Thank you for your help.

Newbie Questions - B&N HD+
Hi - i am going to flash my B&N HD+ for the first time. i have been reading the forums and instructions and have few questions.
i want to do this without SD card (i can go buy one but i if not needed, i prefer not to use it). is this possible? in the EMMC thread, i still see that the SD card must be used for the flashing/booting. so essentially, to flash CWM 6046, is it possible to not use SD card? and if so, can someone tell me how to do that?
Thanks

I have tried many different versions of stock, modular-full, modular-mini and gets a status code 6, I have successfully flashed gapps-kk-20140606-signed, but when I try to use it, the playstore just hangs like it is loading. Can someone advise the steps I need to take to successfully install a working version of gapps?
I have tried factory wiping several times and flashing the various versions of GAPPS.

I'd suggest that you try resetting the Google Playstore app: go to Settings->Apps->Google Playstore, and do a "force stop" and "clear data" (after which you'll need to re-enter your Google (Gmail) account login/passwd).
CM11 M12 - Device Temperature
Hi all,
After staying around on CM10.2 for a long time due to a few issues with earlier snapshots of CM11, I've decided to upgrade to M12. Finding it runs great on everything I'm doing - definitely smoother performance. One thing I am concerned about is the temperature hike of my tablet, particularly when charged and running a game (in this instance, Terraria). Is anyone finding the back running quite hot? Can feel it on the screen and the left side of the device, but the temperature reading of 32C/90F doesn't seem that bad... it does feel worryingly hot though. Not sure if it's something on my end or a common thing with CM11, but I never had this on any other build.
As a sidenote - do the developers accept donations?
Audio stuttering in Rayman Jungle Run
I just did an SD card install of CM11 on a Nook HD+ and it's been working well (thanks!), except that I've noticed that the audio in Rayman Jungle Run and Rayman Fiesta Run tends to stutter / warble, making it unpleasant to listen to. Youtube and Great Big War Game sound are good. I'm using cm-11-20141129-UNOFFICIAL-ovation-sdcard.zip with its initial sdcard image for ovation (sdcard-cwm-early9.img) from the first post. The micro SD card is Samsung class 6 16GB.

Well, what I did, is I found the thread here that describes how to put B&N's OS v2.2.0 on a bootable microSD card. Once I had that working (it's not like B&N is ever going to update the firmware), I did a backup of the Nook's internal storage, and then installed CM11 on the internal storage.
That should solve your performance issues.
Note: You mention an HD+, but then refer to "Ovation", which is the name for the HD, not the HD+. You may want to edit your message to clarify the situation.

Thanks for taking the time to reply. I would have done an internal install, but when I tried to backup the built-in firmware 2.2.0 using CWM 6.0.4.6 (from the OP), I got an error due to the /system partition being unmounted (I'm recalling this from memory; I hope I got it right). I tried using the mount option in CWM, but that failed too. I then said "screw it with the backup... I'll find another on the web", and then tried to do an emmc install of the latest milestone (M12) from the cyanogenmod download site (using SDCARD CWM-based 6.0.4.6 booted from SD... not internal memory), but the install failed with a "status 7" error (IIRC). I also tried using an earlier microSD image (sdcard-cwm-early7.1.img) and tried to install a backup of stock 2.2.0 firmware that I found from another thread here (thinking that maybe I had borked my own from an attempt at installing recovery CWM), but that finished too quickly (yet no errors), and on reboot it didn't appear to have overwritten my own stock firmware. After these efforts spanning a half dozen or so hours of reading, experimenting, etc., I was able to at least get the SD card install working, so I said screw it, I'll just use SD card. But I would really prefer an internal install as you suggest.
I wasn't able to get CWM to boot from internal memory, only SD card (Samsung 16gb class 6). I didn't try very hard though. Maybe this is the reason I can't do an emmc install or backup? Can you only backup internal memory after having booted from CWM recovery (on internal memory, not SD card)?
I was able to find a post somewhere that related the /system problem to rooting, but I never have rooted my Nook HD+ (manufactured Dec'12).
After reading more about the slow 4kB random write performance on most SD cards, I'm thinking of getting a Sandisk class 4 card, but I'd rather not go there if not necessary.
Thanks again.

I'll find another on the web", and then tried to do an emmc install of the latest milestone (M12) from the cyanogenmod download site (using SDCARD CWM-based 6.0.4.6 booted from SD... not internal memory), but the install failed with a "status 7" error (IIRC). I also tried using an earlier microSD image (sdcard-cwm-early7.1.img) and tried to install a backup of stock 2.2.0 firmware that I found from another thread here (thinking that maybe I had borked my own from an attempt at installing recovery CWM), but that finished too quickly (yet no errors), and on reboot it didn't appear to have overwritten my own stock firmware. After these efforts spanning a half dozen or so hours of reading, experimenting, etc., I was able to at least get the SD card install working, so I said screw it, I'll just use SD card. But I would really prefer an internal install as you suggest.
I wasn't able to get CWM to boot from internal memory, only SD card (Samsung 16gb class 6). I didn't try very hard though. Maybe this is the reason I can't do an emmc install or backup? Can you only backup internal memory after having booted from CWM recovery (on internal memory, not SD card)?

It looks like you used the installation files meant for creating SD-based ROM image
See http://forum.xda-developers.com/showthread.php?t=2679899 or http://forum.xda-developers.com/showpost.php?p=42406126&postcount=7 for info/pointers on EMMC installation.

This worked! I now have an emmc install of cm11 M12 from the cyanogenmod site. Since I'm running Ubuntu GNU/Linux, not Windows, I replaced steps 1 to 3 in your instructions in the above link with (at terminal prompt, with microSD card inserted but unmounted):
gunzip emmc-cwm-early3.1.img.gz
sudo dd if=emmc-cwm-early3.1.img of=/dev/sdb
I then mounted the microSD card and copied (as root) the zip files as in your link, all with terminal. The unmounted /system partition error did not appear, and the M12 install went fine! When wiping I had an error related to sd-ext missing, but from some more searching I concluded that it was benign.
Thank you for helping me out. I was starting to give up before the help I've received here. I'm generally really pleased with the performance of cm11 on Nook HD+ so far. I'm not yet noticing much difference between emmc and sd-card installs, performance-wise.
Unfortunately, the earlier performance problem (sound stuttering/warbling in Rayman Jungle Run) is still there using this internal / emmc install vs. the earlier SD-based install of cm11, which suggests that the problem is in cm11 itself. On stock firmware (version 2.2.0 I believe when tested), Rayman Jungle Run ran fine (no sound problems at all). The sound problem may be a slowdown problem, but it's not severe.
