[Q] Please help!!! Noobie messed up NC (big time)

I have a Nook Color. Somehow (and I really can't recall how), I can no longer get to the B&N side of my Nook. Even with the micro-SD out, I still go directly into CYANOGEN. To make matters worse, every single app I try to get from the market will not download. Once I 'Accept & download', the app starts to download then I get an Error overlay screen: "name-of-software" could not be downloaded due to an error.
So I have a V--E--R--Y generic tablet that can't do much. Please help.
Thanx in advance...................................

How did you go about installing CM7? Did you install it to the internal storage?

Please help!!! Noobie messed up NC (big time)
That's part of the problem. I did not consciously install to internal memory, I wanted it to boot from the SD card.

That's what I did...
That's what I did once. I unwittingly installed it onto the internal memory. It also happened to be really buggy. I restored it to stock using Clockworkmod Recovery. Did you use the installer for the SD card?

On a 16GB microSD, I used Win32DiskImager to write 1gb_clockwork-3.2.0.1-eyeballer to a newly-formatted SD card.
I put the ZIP file for: gapps-gb-20110828-signedgapps-gb-20110828-signed, and gapps-gb-20110828-newtalk-signed.
I tried the home-power key combo. It asks me if I'm sure that I want to restore to the factory. I say "Yes" but when the Nook starts up, I'm still in cyanogen mod.
Should I (re-)format the MicroSD, write 1gb_clockwork-3.2.0.1-eyeballer (or another version) then move recovery-clockwork-3.2.0.1-encore?
Aside from not being able to get back to B&N-supplied software, I can't do anything with the NC as an Android tablet.

OP, do you intend to install CM7 into the internal memory?

All I'm trying to accomplish is to get back to the factory NC settings. Once I can get there, I'll decide.

How to hard reset and Factory Default Nook Color - http://goo.gl/pSFui
Power down your NC. Wait approximately 10 seconds or so-- just give it a bit of a break between shut down and factory reset.
Press and hold power button and your "N" home button almost simultaneously-- press Power first and then the N.
Hold these until your screen flashes the "Touch the future of reading" message; hold for a second or two afterward, then release. You will then get a prompt asking if you want to reset your nook to factory. Press the home button to continue. It will ask you to confirm. Press the home key again. Your nook will deregister, reset, and when it reboots, you will see "Kate" in her tutorial video, as if you'd never registered it in the first place.
(Obviously your account info will still be valid-- simply register with your email/pw combo instead of creating a new account.)
Hope this helps- if so please click thanks

I did this (more than once - grrrrrrrrrrrrr!). I never see the "touch the future....." message. Instead, I get a cyanogen mod 7 screen with the message "Booting into Recovery". Then I get a sickly yellow-greenish screen that asks (twice) if I want to teset. I confirm both times then it "wipes" the data. It then boots into a cyanogen mod 7 screen (and the skateboarding 'droid) and I go through the registration process.
Now, when I select a Google app, the downloading (Google Maps) seems to be taking forever, but at least I'm not getting the error I got before.
Also, I do not see the progress of the download that I'm used to seeing on my phone. All I see is "movement" under the "Downloading..." message. How long do I leave it before I abort the download?

Your micro sd card is removed right?

Eyeballer is a clockwork recovery bootable SD image which is used to install stuff (e.g. CM7) to internal memory.
http://forum.xda-developers.com/showthread.php?t=1030227
VeryGreen (size agnostic thread) is the SD image which creates a full OS on the SD card itself leaving the internal memory alone.
http://forum.xda-developers.com/showthread.php?t=1000957
You have used the Eyeballer method and have therefore done an internal install. You must also have installed a CM7 zip not just the gapps zip as they are just google apps and not an actual ROM.
You have 2 ways forward.
The simplest is if you want to end up with internal CM7 and are not interested in running the B & N ROM. Start again by creating the Eyeballer SD card using win32diskImager. Make sure you use a real USB SD adapter and not a card slot on a laptop. Put onto the card the CM7 ROM zip. I recommend the one from the KANG MiRaGe thread in the development forum. It is the most up to date and stable version available at the moment. Also put on one gapps zip (20110828). Now put the card in Nook, Power up and when in recovery then use the menus to format system, data and cache. Do NOT format boot. Then flash the CM7 ROM zip, then the gapps zip. Power down and prepare a clean SD card either by reformatting the eyeballer card with something like the HP USB card utility or a partition manager in the PC like miniTools. You could also use a different SD card if you want to keep the eyeballer one for future use. Put the card back in, power up and you should now be in a stable CM7 environment where you can set up wifi, register with the Google market and download apps.
The second way if you really want to return to stock on the internal and run CM7 of the SD card then use the eyeballer method but instead of flashing CM7 and gapps you now use a return to stock zip. Make sure you still format the partitions as before.
http://forum.xda-developers.com/showthread.php?t=914690
Once you have it back to stock and upgraded to whatever stock you want then follow the VeryGreen method from the link above. Once the SD card has put CM7 on itself, do not worry that there is only a 114MB space if you ever put the card back in the PC. That is normal; it is just the boot partition that the PC sees. The rest of the card can be seen if you USB connect the Nook to the PC.

Yes it is. Also, even though I'm not getting an error, no apps are loading.

You absolutely rock!!!!!!!!!!!!!!
I'm back at the NC "baseline". I tried to go back to a 1.2 (which is what it came with) using "update-nc-stock-1.2-signed". Once I re-booted, it kept returning to the NOOK COLOR screen. Then I used a 1.0.1 from your last post. It came back fine with 2 exceptions. 1) I now have a message that I need to install a SD card. When I do, my (Windows Explorer) "Computer" screen only recognizes the SD card and not the Nook. These are piddly little issues, but if I can get them fixed, great! (Right now, I cannot upgrade the NC or move any books or load any apps.
Thanks again!!!!!!!!!!!!!!!

I had this same problem. Since I am a new member, and can't post links, I'm going to try to help.
Install Clockwork Recovery to an SD card. Yes, the same way you did when installing clockwork to the SD the first time.
There are some threads on other fourms (google is your friend) that have links to Update files that allow you to update while keeping clockwork recovery, and some that will remove clockwork recovery. If you can remove the SD card and boot into the Stock Nook OS, then don't worry about installing 1.0.0 or 1.0.1 like some of the forms say. Just place the .ZIP file of the hacked update (usually 1.3 or 1.4 I think) into the root folder of the SD card, then Install it on your NC just like installing CM7 onto the internal memory. Your nook should start working again. It restored mine to full functionality. I can now pay 3 Dollars for angry birds, but at least its not as terribly slow and laggy as it was with CM7.

I had the same issue last weekend, somehow my internal memory had become unrecognizable to anything, and the local Barnes and Noble store had a SD card that repartitioned the internal memory, and I was back in business. And as an added bonus I now have the 4 GB app/BN partition and the 1 GB mostly useless partition.

The instructions I see when googling around where I see that image mentioned are instructions for installing onto the Nook Color internal memory.
In the simplest case, making an n2a card is much less complicated than that ~ all you need is on the PC, write the size agnostic image, then drop in the CM7 build you want to use, then put the card in the Nook and it creates itself. There are upsides and downsides to different n2a methods, but that one seems to be the easiest ~ I've done it successfully several times, and I'm certainly nothing like an expert when it comes to these Android systems.
A recovery card image will make a bootable recovery card ... and while that might not have been what you needed to get what you want, its what you need to get the nook back to stock.
You might want to go to
http://forum.xda-developers.com/showpost.php?p=22809801&postcount=148
... to get a version of the 1.4.1 upgrade that your recovery card can install. You'll probably have to wipe all sorts of partitions, which means you'll have to sign in with the B&N store again and you'll get to download you B&N apps again, but that's pretty straightforward.
This OP in this thread:
http://forum.xda-developers.com/showpost.php?p=10623716&postcount=1
... says that it will be necessary to format ("wipe") the /data and /system partitions, but it doesn't seem like you'll lose anything you want to keep. After all, you've either overwritten or completely tangled up your stock B&N info.
That post above has 1.4.1. There should be a signed 1.4.2 lying around somewhere, but if not, once its back to stock, you can update to 1.4.2 the normal way, download the B&N update file, drop it in the root of the Nook, make sure its at least 30% charged, and let it go to sleep, which will run the update file.

Black screen of death

I used ManualNooter for my nook. As I recently installed a bunch of apps and ebooks, I thought I should back up my device. I went to Rom Manager for back up which then brought me to CWM when it was done to reboot. When I reboot it was stuck in boot loop. I turned the nook, then back on and whenever i reboot i get black screen of death. I can boot to CWM by holding all three buttons down. I tried wiping data, factory reset, reinstalling nooter zip, yet every time I reboot, I get black screen of death. Can someone help me figure out how to fix this? Thx.

My computer no longer recognizes the Nook (I have an HP laptop running Windows 8). Prior to the black screen, the computer did detect the nook when plugged in with the USB cable. How can I now copy the zip file to flash through CWM recovery? I have version 3.2.0.1 installed? I don't understand why trying to make a back-up file through the ROM manager would cause such failure? Thanks for your help.
EDIT: Should I now be trying the verygreen method via SD card? Apologies for the panic.

Make a bootable CWM card as described in my item A10. Then copy the 1.4.3 rom zip downloaded from A15 to the card. Put the card in the Nook, boot to CWM and flash the ROM zip.
Sometimes files get corrupted when writing them to the Nook. Obviously that is what happened with ROM Manager.

What size SD card do I need? I tried copying the 1.4.3 rom zip (unzipped, used 7 zip to extract the other files) onto a 8 GB sandisc and a 16GB and both tell me the card does not have enough space. I've used Win32diskimager-v.07 (the link from manual nooter no longer works), I copied the CWM-5.5.04 image to the SD card. I had no trouble copying manual nooter onto the 8gb sandisc. I used a SD formatter program to format and wipe the disk before using it for this. Thanks.

I guess I should modify my instructions. The 1.4.3 zip is so large that you need to use the 6.0.1.2 version of the bootable CWM SD. It has a little more room for the zip. It does not matter which size card you start out with.

I'm back in business! It worked - whew! I had trouble with the 1.4.3 zip, so I used DizzyDen's 1.4.1. I was stuck in boot loop the first time I rebooted, then used the 5-6-7 partition fix zip, reinstalled the 1.4.1 zip and it worked like a charm. I also used the newer version of CWM you advised which was smaller in size, it's all on the 16gb SD card with no issue.
One last question, now that the stock rom is in order, am I safe to flash CM10? I'd prefer not to use manualnooter again as you said in a previous post, CM10 is leaps and bounds above nooter. If you think it's okay to flash, do I have to do the 8 count reset to fully wipe?
Many, many thanks for your clear, detailed instruction and patience!

When I was last working on this, I had my external hard drive plugged into the computer via the usb port. I was backing up the files that were on my micro sd card, I had a 16gb in my droid bionic, I swapped it with the 8 gb I had in the nook when I couldn't get the older version of CWM on the card. Now when I plug in my external hard drive, all I see are the win32 imaging files on it. I take it, this process formats over everything plugged into a usb port? I've lost all my kids photos and videos, I can cry I'm so mad at myself for letting this happen. I've tried the two laptops we have and I get the same list of files in the folders. I guess this is one of those mistakes you only make once.

Oh no! Yes, burning a card writes over everything. There are some utilities that may let you rescue your old files, but maybe not. I would set it aside till you find out. I think the free MiniTool Partition Wizard has some paid companion products that may help.
Edit: just reread your post. It does not write over everything plugged into the USB. You just made a mistake when you burned once and selected the external drive letter. The same solution applies. Find a disk partition repair utility.

Am I able to copy files to the SD card while it's running CM10? I wanted to copy some pdfs and ebub books to read and when I try to copy to the SD card it says the Nook is not responding or disconnected. I don't think this is a driver issue as I can see the Nook on my computer and can see the files stored either on internal storage or SD. When I'm in CM10 and go to file manager, I can only see what is on the SD card, I can't access any of my files that were on EMMC. That's fine, I have copies of my ebooks saved on my laptop, I just can't figure out how to read them now. Any thoughts?
Thanks.

You need to be a little more specific.
There are two methods to connect to your PC with CM10 using the USB cable, MTP and USB mass storage. They are selectable in settings. Go to settings, storage, menu and USB computer connection. MTP is default and shows the Nook as just devices in Windows Explorer with no drive letters. If you choose USB mass storage, they show as drive letters in Windows explorer. But they do not contain anything until you activate them by touching a button on your Nook. And the button does not show if Android degugging is activated in settings.
So that is why I say you need to be more specific.
You say you can't copy to the SD. What are you seeing on your PC, drive letters or just labels that say internal SD and sdcard? And describe a little more the errors.
The reason you can't see emmc with the file manager that comes with CM10 is by default it is in safe mode. You have to change a setting to get it in root mode. Either get a different file manager like the free Root Browser Lite or change the setting in the CM10 file manager. To change the setting, press menu while it is open and you will see three dots in the lower right. Touch that. Go to settings, general settings and access mode and change it from safe to root. Then you will be able to see emmc.

I think my quick reply didn't post. Anyway, thanks, again, for your help. When I went to transfer files from my external hard drive to the Nook, I was using the wrong lap top and then realized I had to update usb drivers which helped. I then followed your other steps to change settings, including safe to root, and I can now see all my files.
Can you recommend a file manager? The default one is a bit cumbersome.
Thanks again for everything.

The 5/4 nightly is CM10.1. The version you were running earlier was CM10. You should be able to just flash the 5/4 nightly with only wiping the dalvik-cache. No other wiping or partition zips. Since CM10.1 requires a newer gapps (20130301), you should flash that too.
Yes, I still use ADW, but only because I am used to it and do not want to try something new.

Is there any difference in performance running CM10.1 off emmc vs SD card which I'm presently doing with the April 7 nightly? I have some vague idea that I read a while back once you put CM10 on emmc you could no longer return to stock?
If I stay on SD card is there any harm in trying (I think the name is Dean) method to adjust internal partition for more room for apps? I've run out of room on SD card? Or is using Titanium to move files a safer alternative?
My kids are now using the Nook, I won an ASUS tablet from livinginkaos over at the Droidrzr forum. He had a give-away while fundraising for a root exploit bounty for JellyBean which Dan Rosenberg created. Method works using Linux Ubuntu, that forum is awesome. I was singing your praises to them.

[GUIDE/TOOLS - NOW OBSOLETE] HDplus CM10/10.1 Easy Install Guide for Legacy SD

UPDATE 05/28/13 - Now that verygreen has changed his SD scheme to his new version, this guide should not be used on his ROMs dated 5/27 or newer. Use his new image and follow his new instructions. If you want to see the old instructions click on the Show Content button below.
Click to expand...
Click to collapse
Many users have had difficulty installing the HD+ CM10/10.1 ROMs using the Original/Legacy (verygreen) SD setup (especially Windows users). I have written this guide and have made some tools that should make it easier. No need for ADB or Linux. I have upgraded the CWM (clockworkmod) recovery to version 6.0.2.8 which includes larger fonts, a brighter screen and the ability to use the internal storage for installing zips and performing backups. It also uses verygreen's process from his early4 zip that aligns partitions at 2M. This guide and tools are for the Original/Legacy SD setup by verygreen, not the Hybrid. If you want the Hybrid, go here.
Setting up the SD
Begin by downloading the files you need either with stock or your PC. You will need my updated SD image file, attached below (do not use the early4 image from the verygreen thread), the CM ROM zip you want to install and the gapps zip to match it. Put the last two zips on your internal media sdcard built into the HD+. You can get the HD+ CM10 ROMs here and the HD+ CM10.1 ROMs here. You can get the gapps zips here, 20121011 for CM10 and 20130301 for CM10.1.
Extract the SD image zip and you will have a 117MB .img file. Burn that to your SD with Win32DiskImager in Windows or the dd command in Linux or OSX. The SD needs to be at least 4GB and preferably a SanDisk Class 4.
To use Win32DiskImager, find it on the web (here, it's free) and install it on your Windows PC. Open it (be sure to run it as administrator) and select the drive (device) that has your card reader with your SD inserted. Then in the image file box put the location where you have the extracted img file. Then when everything is set right, click on the write button. A warning will pop up asking if you want to proceed. When you have verified that you are going to write to the correct device, click on Yes. (One user overwrote their external USB hard drive by not verifying first.) If you get an error message about access denied, it means you are looking at the drive with Windows Explorer. Close Windows Explorer and try again. In fact, it is a good idea to close all unnecessary windows when burning, even your browser.
When burning is complete, insert the SD into the Nook and boot. It should boot to the cyanoboot logo and sit there for a little while while it creates the other partitions on the SD and formats CM10SDCARD. Then it will end up in CWM for HD+ Original SD. If it does not leave the cyanoboot logo within a reasonable time (it hangs sometimes), just touch the power key and CWM should come up. To use CWM, press the volume up/down keys to move the cursor and the n key to select an item. The power key is the back button.
Installing ROMs
You can use the "install zip from SD/choose zip from internal memory" option to flash the CM ROM you downloaded earlier to your internal memory sdcard. Then you can flash the right version of gapps to match your ROM.
When you reboot (you need to leave the SD in the slot), the CM ROM should start. You will need to register with Google to set up Play Store.
If you later want to upgrade your ROM to another build, download it to your CM10SDCARD partition using CM. Then boot to CWM and flash it.
Backing Up
This version of CWM lets you back up and restore your setup. You can even back up to internal memory. It does not back up /boot, but does back up /system, /data and /cache.
Swapping EMMC and SDCARD
Some users have installed CM to a small SD card and want their apps to use the large internal media storage to store their data. I have developed a couple of zips to swap EMMC and SDCARD when booted to CM so that internal memory is available to your apps to store their files. One zip will add the swap and one will remove it. Get them attached below.
These zips can be flashed with CWM but will only install to the Original SD with CM. I just fixed a bug in the rev0 and rev1 zips. If you already flashed rev0 or rev1, you need to flash the remove zip before you flash the rev2 fixed version. No need to boot in between.
With rev2, both SDCARD and EMMC will show internal media storage, as will both MTP folders. A new folder, ext_sdcard, will show the external SD media partition.
Updating earlier versions of CWM
Updating prior installs of the Original SD installation to this new version of CWM is easy. Just download the ramdisk zip file attached below and extract the file. Put your old SD setup in your PC and rename the ramdisk.cwm to ramdisk.cwm.bak. Then copy the new ramdisk.cwm you just extracted to the card, replacing the version that was there. Next time you boot to CWM, the 6.0.2.8 version for HD+ Original SD will be there.

Yes, you can use bokbokan's hybrid image to do it the same way for the HD. And I think his standard image does it too.

question...
Sorry if this has been answered somewhere else but, I did this using a 32gb card and everything I running smooth. I have a 64gb card that I want to switch it out for. I know it won't be a problem doing the root and all of that again, but I was wondering if anybody knows how to change the 32gb SD card back to normal? When I stick it in my computer all it shows is the boot partition and when I try to format it, it only formats that's partition. Meaning that my 32gb card turns into a worthless 116 mb card. I've tried on windows and Ubuntu and get the same results...
So does anybody have any suggestion?

Thank you, I will try that and let you know how it works

This is probably a stupid question, but once I've got the SD card set up properly, can I then go ahead and delete the ZIP files that I've installed? Or do I need to keep them kicking around? Figure if I can free up some space, I should.

You can delete them if you want, but I usually always keep them somewhere so I don't have to redownload them if I need to reflash, which very oftern I have to for various reasons. I can always delete them later if space becomes an issue.

*nod* I meant deleting them off the SD card (should have specified). I'd be keeping them on my fileserver to ensure that I can reflash the sdcard to the same version I started with if I need to.

Setting up the SD
Begin by downloading the files you need either with stock or your PC. You will need my updated SD image file, attached below, the CM ROM zip you want to install and the gapps zip to match it. Put the last two zips on your internal media sdcard.

I'm confused by this, what are you referring to as "internal media sdcard"? I used win32 to burn the .img file, then booted into CWM...I'm clearly doing this wrong, because after that, the sdcard only has 117mb and no room to put ROMs on

You are doing it right. 117MB is what it is supposed to have. You do not put the files on that card. You put them on the HD+ (on the internal sdcard).
If you could see that it only had 117 MB, you were not booted to CWM, you were looking at the SD while it was still inserted in the PC. Booted to CWM means it is in the Nook.
When you insert the burned SD into the powered off HD+, then turn it on, it boots to CWM. That is what I mean by booting to CWM.
The internal sdcard means the storage that is built into the HD+ (that is why I call it internal). Boot to stock and download the files with it. They get put on the internal sdcard or "sdcard" as it is called. After you insert the burned card into the HD+ and boot to it, CWM has the ability to flash the zips by reading them from the internal sdcard built into the HD+.
Edit: I just clarified that in the OP. It is hard to anticipate how users will interpret your words in advance.

You do not extract the cm zip. You extract the image zip which is attached to the post. It is the one that is 120 MB and is the one you burn to the SD with win32diskimager.

thank you for the help. i appreciate it! i can now use my new HD+ (bought it last night) to its full potential.

I just wanted to say that I was suffering from the dreaded "Nook refuses to boot from the SD card" syndrome. I tried three different SD cards burned using four different computers, to no avail. Tried this patch? Worked perfectly. Thanks! :laugh:

SDXC cards viable for this use?
Well, that registration video was a real interesting bit compared to most forums I've ever used. Somebody put a lot of work into that.
I'm noticing a lot of emphasis on Class 4 cards. Impetuous sort that I am, I already obtained a Sandisk Ultra 64 GB microSDXC (Class 10/UHS 1) card for this project. Best Buy had a good deal and I was hoping to have a lot of room to work with and it wasn't clear what access to the internal storage would be available or best left alone. Has anyone had success or great problems with this card?
Other than that issue before attempting to execute the install, this is a very helpful thread. Much clearer than verygreen's original. That shouldn't be taken as an insult to verygreen as technical writing for those outside a project is not a skill everyone has or should have. Asking those deep within a project to shift mental gears to operate at the outsider's level can be a waste of resources and is often better delegated to a specialist. And we should be thankful for those specialists when they volunteer like this.

Some have had good success with that card, especially if they use my Hybrid setup which uses less of the SD to operate from.

It appears to be working on the first try. I'm currently syncing my app set from the Play store. It looks like this will be a huge value add for the Nook. I wouldn't have bought it if the full Android option weren't there. I just hope enough of us still buy books from B&N to keep them going.

[HOW-TO] Installing CM11 Internally on Nook HD+

[Caveat emptor: adopt/follow this guide at your own risk].
FWIW, here the process I used to install CM11 internally (on emmc*) on my HD+:
Using a disk partition tool (such as MiniTool Partition Wizard Home Edition) create on SD card a Primary FAT32 partition, and set the partition ID type for the partition to 0x0C FAT32 LBA and set its Active flag. Once this is done, the partition should appear as a (read/write accessible) drive under Windows.
Use an archive file manager such as 7-zip and extract the .img file from verygreen’s emmc-cwm-early3.1.img.gz (http://forum.xda-developers.com/showpost.php?p=49192422&postcount=1)
Use the archive file manager to extract the files from the .img file and copy them to the SD card: first MLO, then next u-boot.bin, uImage, kernel, ramdisk.cwm.
Copy to the SD card:
verygreen’s flashable CWM recovery zip file cwm-recovery-ovation-6.zip (http://forum.xda-developers.com/showpost.php?p=49192422&postcount=1)
the zip file of CM11 ROM build of your choice – e.g., from http://download.cyanogenmod.org/?device=ovation (see http://www.cyanogenmod.org/blog/cm-11-m4-post-release-items for considerations in choosing nightlies vs. snapshot/stable builds)
the zip file of the Gapps package corresponding to CM11 – e.g., http://opengapps.org/?api=4.4&variant=nano
Put the SD card into the HD+, and boot from its power-off state.
[Optional step but highly recommended] Select Backup to backup your HD+ current ROM config (/boot, /recovery, /system, and /data).
Select Wipe data & factory reset.
Select install zip from SD card and install flashable CWM recovery zip file.
Select install zip from SD card and install CM11 zip file.
Select install zip from SD card and install Gapps zip file.
Remove SD card and select reboot.
Once the HD+ boots up, set up the wifi connectivity and your google account info.
If the Nook fails to boot off SD -- the two most common symptoms of failed SD boot and their likely causes are:
The HD+ boots straight to stock -- most likely the boot partition's type and/or flag are not correctly set, or the HD+ cannot find the MLO in the boot partition (make sure that MLO is the very first file to be copied to the freshly made /boot partition).
If the HD+ consistently boots straight to stock in spite of a valid /boot partition and boot files, it's possible that the tablet is one of those HD+ units that have difficulty booting of SD cards, see http://forum.xda-developers.com/showthread.php?t=2288688 for more info and potential remedies.
The HD+ screen stays dark for seemingly a long time then eventually boots to stock -- most likely the MLO or u-boot.bin are corrupted. When in doubt, compare the size of the two copies of the files in bytes.

What to download?
Hey Guys,
First off I really appreciate the time you take to answer my questions.
I still need some guidance however.
Again I have "Android 2.2" The last stock upgrade they updated.
So with that being said. What files should I download, and what order.
Everyone is giving me different links and i am not sure what to do.
This is my first time every doing something like this on a nook or tablet.
So please be patient with me. I would greatly appreciate it.
Should I download the cyanogenmod software first to my nook folder on my computer desktop, and then what other files do I need?
Once I download them I plan to transfer them over to a card for my usb slot that is on the bottom of my nook I am assuming, correct?
Once I have the software I need, Then I need to know what order should I install what first.
When I am doing this software installs. Do I need to worry about what is on there now.
This is nothing I need to save so I am not afraid of loosing what ever is on the nook at the moment.
All of this stuff can be let go or deleted or refresh install. Don't care.
I just want to get my table to work like a computer basically. So, I can watch the videos that i want to watch on my tablet, and still
be able to surf the net and read internet websites, you tube .com and other websites I like of course.
By doing this process this will still allow me to do this I am assuming. Again, I have never mode so I am not sure what this
cyanogenmod is or what it can do to help. I am game for trying to do it if it gets me what I want it to do.
I did see the other links posted above. I just diidn't know where to start or what to download first do to the fact I have only 2.2 android software on my nook color hd+
Again, I appreciate the advice peeps!
Please elaborate if you can with what links and what to do. Thanks again. Karl

First of all, you need to realize that installing any kind of aftermarket ROM on your android device will void your warranty with no manufacturer support.
Second, installing ROMs is inherently risky, since there is always the possibility of bricking your device.
Thirdly, any kind of ROMs that you see in the Android Development section are not completely stable; they are usable but there will be bugs & glitches. So all ROMs come with a caveat: use at your own risk!
That being said, here's how it works:
You will need three files; (a) SD Card Image (b) Recovery Image (c) ROM that you want to install.
For this purpose I am using CM11 as the example, the thread is here.
[1] Every Android device has a manufacturer installed recovery program; to install a custom ROM you need to have a custom recovery. This custom recovery is what allows you to make changes to your Android device.
[2] The Nook HD+ has the advantage of being able to boot from its SD card slot (kinda like a computer booting from a CD/DVD drive).
[3] Download the image files and create a bootable SD card. Copy the Recovery Image and the ROM to this SD card. You will need WinImage to create this card in a Windows computer.
[4] Insert this card into the HD+ and reboot your device. Here's the kicker, the HD+ may not boot from the SD card and may simply go to normal boot. If that happens you will have to keep repeating it. Check older threads about this issue.
[5] Once it boots from the SD Card, follow the instructions listed in the first post of that thread.
Brief summary (this is true for most devices): Create a bootable SD card, use this card to boot the device, install Custom recovery into the device, then install the ROM. Once you have a custom recovery installed, you won't ever have to use the bootable card again unless you run into some issues.
Good Luck!

For Hirent.
Hirent,
First off, I want to say thank you so much for the very detailed reply you sent my way.
I will use this with digression of course. I am aware of the warranty issues that it will cause.
The one major question I have before I dive into this project.
I am aware of the possible bugs and how it is not perfected.
Will this enable me to download and install flash player on a updated android that was suggested in this article you posted?
Or will it just work automatically after I do the project of these software installs. Another words I will be able to open chrome or factory
browser and go to NHL.com, MLB.com, NBA.com and other s and play the videos on the Nook HD+ Color after installs or no?
Thanks for the advice, help, and replies.

New Issue with SD Card 8gb, Centon
Hello,
I tried to follow the instructions on deleting partition on SD card. I also did get it wipe. But, the new issue is I am not able to go any further in the process.
I tried to read the card in my computer and now the card is not being recognized by windows on "my computer" It is H Drive.
IT was now its not. I deleted partition then was going to try to create the new partition. That was not highlighted on the partition magic software.
The article I was following was this.
https://www.youtube.com/watch?v=fLbr1Uyr0sk
Now my SD card is not being recognize by windows 7 ultimate.
I also tried to do the right click trick on my computer then computer management. Then did click storage and then drive then so on.
However when I did that, only that screen recognizes my sd card before and after. But no other screens like my computer screen.
What do I do next with this card to continue. I was trying to follow that tutorial above then go to the windows disc 32 part.
Then drag the software over to start installing it on my nook. But, obviously I never got that far. Can you help me get the SD card to work again and tell me what I did wrong and what to do next so I can move forward to add CW & whatever android software will work well with flash. So I can use the other sites I mentioned in my other post.
If anyone can help I would appreciate it. I am stuck and not sure what to do next.
---------- Post added at 05:41 AM ---------- Previous post was at 05:33 AM ----------
Weird.
I just put the sd card in a usb card dongle that inserts the sd card into usb thumb drive and all of the sudden I see the drive on this computer now.
What should I do now?
Do I still have to go and do the windows disc 32 imager part.
Then drag and drop the software I need and drop in the card to my nook then install.
Or just drag software that I need like CM and Android and move forward with that.
Which should I do first. If it is the later part, which CM and Android should I use for the Nook color HD +?????
Thanks again for help and sorry about that first post, I swear it was it seeing it before. Weird.
Thanks, Karl

What tablet are you having this issue with?
AFAIK currently there is no CM12 nightly build yet for the Nook HD+ ("ovation") or HD ("hummingbird"). Make sure you pick the CM build specific for your device (e.g., cm-11-20160208-NIGHTLY-ovation.zip for the Nook HD+); using a ROM build for a different device can brick your tablet.

Thanks for your quick reply. This must be the problem. I originally installed the CM11 and Google Play did not work so I went out and found another 'walk through' via the link given to me last time and thought CM12 was the right choice.
I'll go back and reformat after getting the right gapps for CM11.

Thanks, so what I did go back and reformat the sd card and start over with the early, cm recovery ovation, cm11, gapps 4.4; however, apparently I didn't unzip and copy the early correctly because after I rebooted the hd+ after going through the wipe/install process, I got an error that the setup wizard could not start. I powered off, wiped the sd card and began again following directions very carefully making sure the MLO was copied first.
Now, it seems I have somehow bricked the device because it will not power on and has only a green light when plugged in, instead of the normal amber. Any ideas of how to get it to turn on and boot to the SD again?
EDIT:
Okay, as I stated in my edit, I got it to boot, but I'm still getting the popup "Unfortunately, Setup Wizard has sopped. Any ideas?

Did you do a "wipe /data & factory reset" before you flash/install the zip files of CM11 ROM and GApps?
Did the installation of the 2 zip files succeed without error messages?

I got it working after I got it to bypass the error by dragging down the menu and connecting to wifi. Once I did that I was able to set up the Google account and everything was fine thereafter. There is a bit of flickering now and then, but everything seems to be working fine now. Thanks so much for your time and help!!!

Recover Data?
Hi,
I've jut reinstalled cm11 onto my nook HD+ & realise I failed to copy a text file over before I formatted the HDD. Is it possible to recover a deleted file off the nook HDD via a PC? I've tried changing the developer option settings - Android debugging on, ADB Over Network on & connecting via USB both MTP & UMS (I think that's what they were) but when I run any of my Data Recovery programs in win7, the drive isn't recognised as an option to recover from.
Any help would be appreciated,
Thanks

[HOW TO] Installing LN14.1 Internally on Nook HD+

Caveat emptor: adopt/follow this guide at your own risk.
Below is a procedure that can be used to install amaces' LN14.1 (ref: https://forum.xda-developers.com/nook-hd/development/marshmallow-nook-hd-hd-t3239269) internally on a Nook HD+ :
Download sdcard-reco-ovation.img.xz from amaces' repo https://notredame.app.box.com/s/26a4bygh9vbaw7jjq08xr5evomvaw5ww/1/3332706778, unzip it (using e.g. 7-zip) and use win32diskimager to write the unzipped content sdcard-reco-ovation.img to a SD card.
Download and copy to the same SD card:
amaces' flashable TWRP zip file, e.g., twrp-3.0.1-0-ovation.zip ( https://notredame.app.box.com/s/26a4bygh9vbaw7jjq08xr5evomvaw5ww/1/3332706778)
amaces' flashable LN14.1 ROM zip file, e.g., lnos_ovation-ota-NMF26Q.170104.zip from https://notredame.app.box.com/s/26a4bygh9vbaw7jjq08xr5evomvaw5ww/1/3332706778
the flashable zip file of Gapps' corresponding pico package open_gapps-arm-7.1-pico-2017[mmdd].zip from http://opengapps.org/
Turn off the Nook, insert the SD card, and boot the Nook from its power-off state.
[Optional] Make a backup of your stock ROM & Apps: to backup onto the Bootable Recovery SD card you'd need to make the boot partition on the SD card large enough to hold the backup of your stock ROM and its Apps -- see my post #7 below.
Select "wipe data & factory reset".
Select "install zip from SD card" and install TWRP recovery zip file.
Select "install zip from SD card" and install LN14.1 zip file.
Select "install zip from SD card" and install Gapps zip file.
Remove SD card and select reboot.
Once the HD+ completes boot-up (be patient as the post-installation initial boot would take 3-5 min), set up the wifi connectivity and your google account info.
If you run into problems during initial setup:
- absence of WiFi network setup step: see this post
- setup process crashes (as have been reported with some combos of ROM and GApps build versions): retry the clean install process with the sequence of steps # 5, #7 & #9 (i.e., skipping over step #8 flashing GApps) and complete the initial setup, then reboot into TWRP to flash GApps; see also https://forum.xda-developers.com/showpost.php?p=72104906&postcount=37 for solution for other setup crash causes.
To enable "Root", see https://forum.xda-developers.com/showpost.php?p=72185622&postcount=1915.
Notes
- This procedure can also be used to install amaces' AOSP7.1 ROM (instead of his LN14.1 ROM).
- If your HD+ is currently running CM11/12/13, see https://forum.xda-developers.com/nook-hd/general/how-to-updating-nook-hd-internal-emmc-t3562818 for an alternate procedure which does not require use of a SD card.
Please post any comment/question on the features or performance of AOSP & LN ROM builds on the Developer's thread at https://forum.xda-developers.com/nook-hd/development/marshmallow-nook-hd-hd-t3239269.

I used these steps and can confirm that it works. I came from stock ROM. I understand that there's a risk since I did not do a original ROM backup.
So far, I am impressed by the work that have gone in to make it happened from so many volunteers.

Good point! Thx

I did this on my Nook HD yesterday. Everything seemed to go correct, however my tablet will not power off. If I power off it immediately restarts. I saw a similar problem mentioned with another build but can't seem to find the thread that was referenced.
edit: I found this thread https://forum.xda-developers.com/nook-hd/development/marshmallow-nook-hd-hd-t3239269/page166 which implies this is a known problem.
Holding the power button beyond the shutdown screen worked! The tablet powered off and stays off. Phew.
Can I take a moment to say thank you. I have owned a Nook HD and Nook HD+ for almost four years. I am not very technical but did do some modding of them to enable unknown sources, the very basic you could do. The tablets were really sluggish with the original OS but we muddled through. Last week the Nook HD froze at the boot screen and the only way to resolve was a factory reset. I figured the time was right to do something more permanent and followed your instructions.
The only issue I had was I was not able to do a backup. I used an 8 GB SD card. When I used win32diskimager to write the unzipped content sdcard-reco-ovation.img to the SD card for some reason the size of the card changed to ~900 MB. So the SD card didn't have enough space for the OS backup. I redid the card several times but it kept happening. Not sure if you know what I did wrong, but I hope its moot since I hope to never to have to go back to the Nook OS.
Very sorry for the long message, but I am excited with the prospect of having a tablet we can actually use. I plan to do this to my HD+ but that one is still working and has a ton of content that I know will be lost. But I think I have to do it.

Bootable Recovery SD card images (such as Amaces' image in this case) are usually intentionally made just large enough for users to add necessary flashable zip files for ROM/GApps/Recovery yet small enough to fit in the smaller size cards a user might happen to have laying around. It's possible but more tedious (and thus potentially error-prone) to create a Bootable Recovery SD card with custom size of up to 16GB for the boot-partition -- I'll post a short guide for this.

Process for Creating a Bootable Recovery SD card for Nook HD+
[Caveat emptor: adopt/follow this guide at your own risk].
Below is the process for creating a Bootable Recovery SD card for flashing ROM/GApps/Recovery on a Nook HD+:
Using a disk partition tool (such as MiniTool Partition Wizard Home Edition) create on a SD card a Primary FAT32 partition of size no larger than 16GB, and set the partition ID type for the partition to 0x0C FAT32 LBA and set its Active flag. Once this is done, the partition should appear as a (read/write accessible) drive under Windows.
Use an archive file manager such as 7-zip and extract the .img file from amaces' sdcard-reco-ovation.img.xz ( https://notredame.app.box.com/s/26a4bygh9vbaw7jjq08xr5evomvaw5ww/1/3332706778 )
Use the archive file manager to extract the files from the .img file and copy them to the SD card: first MLO, then the rest of the files u-boot.bin, uImage, kernel, ramdisk, ramdisk.cwm, ramdisk.stock, and the folder OLD.
Copy to the SD card the flashable zip files for the ROM/GApps/Recovery/etc. that you'd want to install.
Notes
The most common symptoms of failed SD boot and their likely causes are:
The HD+ boots straight to stock -- most likely the boot partition's type and/or flag are not correctly set, or the NT cannot find the MLO in the boot partition (make sure that MLO is the very first file to be copied to the freshly made /boot partition).
If the HD+ consistently boots straight to stock in spite of a valid /boot partition and boot files, it's possible that the tablet is one of those HD+ units that have difficulty booting of SD cards, see http://forum.xda-developers.com/showthread.php?t=2288688 for more info and potential remedies.
The HD+ screen stays dark for seemingly a long time then eventually boots to stock -- most likely the MLO or u-boot.bin are corrupted. I have had this happen to me a few times in the process of extracting them from archive zip files.
The boot partition size is too large -- for some reason the HD+ cannot boot on boot partition of size larger than 16GB.

Fantastic write up.
Everything went flawlessly.
I notice that my device is no longer rooted. Is there a relatively quick way to re-root now that I've completed all the steps in your original post?
Thanks for such a well written guide!!

Root is built into this ROM and can be enabled in Settings->"Developer Options", but because of a current bug you'd need to enable it, then disable it, then re-enable it again.

Let's just say that you effin rock!!
:highfive:
Problem solved.

Sorry, double post........

After getting root access as described above in post #9, I installed SuperSU and SuperSU Pro from Play.
Once the binary updated and I rebooted, I was stuck in a bootloop. I had to reflash the entire process to get the HD+ operational again.
Is this normal? Did I miss something? Does SuperSU not work with this ROM?
I see that the ROM has "Privacy Guard" which looks to be a form of superuser. Ti backup isn't happy with the stock SU and would prefer I install SuperSU. I would love to install SuperSU but don't want to reflash from scratch again.
Any tips/help would be greatly appreciated!

I believe the "Manage root access" menu in Settings->"Developer options" is meant to eliminate the need for root-access-management apps.

I don't see that option after flashing aosp_ovation-ota-NOF26W.170226.zip
Do I need to reflash, and let CWM fix for root?

Did you not see "Manage root access" under Settings->"Developer options", or not see "Developer options" itself?

Apparently "Manage root access" is only available on LN ROM.
For AOSP ROM it looks like you still need to install SuperSU, see https://forum.xda-developers.com/showpost.php?p=71063379&postcount=1647.

Thank you for the work on this. Mine is HD Plus.. Only problem I'm having after upgrade is the unit ignores "Power off" and seems to turn itself on after about 30 seconds of black screen and boots back up. Battery is at 100%, and I disconnected the USB cable, nothing is connected. Anyone else seen this?

I am running lnos_ovation-ota-NOF26W.170226 and have not seen this problem with this build as well as the previous build.
Did you do a "wipe /data & factory reset" before flashing the ROM/GApps zip files?
Also, this thread which has a much larger set of reader might be a better place to post and get help with questions like yours.

I did it on two systems, one is 16GB the other 32GB. The one that keeps turning back on was one was upgraded from CM11 (32GB), the other was virgin Nook OS . Yes, I did wipe /data and factory reset, formatted cache, etc.
