Tried so much! Not booting...

Thanks for this guide, but I'm running into a wall here on getting the NC to boot to the image.

I had this NC for over a year running CM7 on an SD card, wanted to update it to CM10, so started with your guide.

I used a 16GB SanDisk Class 10 for the CM7 install, so using the same card when attempting CM10, I tried all the steps using my laptop's built in SD card reader (in spite of instructions, just in case I got lucky), no dice. So I went ahead and bought an external SD card USB reader and another 8GB SanDisk Class 4 just in case.

Using the new USB card reader, both SD cards, I've tried WinDiskImager, tried WinImage, tried generic-sdcard-v1.3-CM7-9-10-10.1-10.2-larger-Rev7.img, CWM-6.0.1.2_bootable_SD.img, CWM-5.5.04-bootable_SD.img.

Every time, I write the image, pull the USB stick out, put it back in, copy the cm-10.2.1-encore.zip and gapps.zip to the drive, pop out the USB, pop out the card, put it into the powered off NC, power it on, get the n loading screen, then it boots to Nook OS. Every time.

Also tried plugging the NC USB cable into the PC instead of using the power button on the NC.

Just factory reset it, too. Then tried a large combination of the above steps all over again. Still no dice. I've read your tips and tricks for A9, A10, read Taosaur's guide.

If I power it on and press the N/Home, I don't get boot options, just saw a reset option.

Is there something else I can try?
[Nook Color General] leapinlar:
Do you have access to a different PC?
[Nook Color General] SirCasey:
I tried a lot of these between both laptop and desktop with the usb reader, but not all. Is there something specific I could do?
[Nook Color General] leapinlar:
I am amazed that you had CM7 running on SD with this device but cannot get it to boot now. What has changed? Different PC's? Running new versions of Windows?
[Nook Color General] SirCasey:
Me too! I didn't think it would be this much of a hassle or I would have left CM7 well enough alone.

I think I did it from a machine I had a year+ ago, or also from the same laptop since that hasn't changed. In all events, using Win7.

I suppose I should give up on trying the SD boot approach and go for writing to the emmc?
[Nook Color General] leapinlar:
But you said you could not get the 5504 or 6012 CWM SDs to boot either. You can't put anything on emmc without that. Try using someone else's PC if you can.

Cm 10.2 and jb

i get the nook to boot to the bootloader with the little penguin which does what its supposed to. I take out the sd card after it shut down itself and installed the gapps-jb but when i restart the nook all i get is a blank screen (after the cyanbot loads the sd01)? what did i do wrong here?
[Nook Color General] leapinlar:
I don't follow you. You copy the gapps-jb file to sd boot partition, insert the SD, boot and you get the cyanoboot logo? Are you then pressing n to get the menu and then selecting SD recovery? Then you get a blank screen?
[Nook Color General] jacobrosen2:
Yeah thats exactly what i did. i first wrote the image, the generic sd card, then i installed cyanogenmod 10.2 into the boot partition. removed the card safely let it run on the nook. once it powered down took it out and then installed gapps-jb into the boot partition and plugged it back in. loaded recovery and said it completed but once i turned it back on and run SD01 i get just a blank screen
[Nook Color General] leapinlar:
So the gapps-jb installed successfully? What version did you use? And did you boot up to CM10.2 successfully before you installed gapps?
[Nook Color General] jacobrosen2:
i installed the the most recent jbs the one it had directed me to. but i didnt think of booting it without it to see what would happen. im trying it again right now after wiping the card again but now the .img will not complete on the sd card (im on a mac)
[Nook Color General] leapinlar:
I need to know the date on the filename, not just "the most recent". If you installed the wrong version of gapps that could be the problem. And if you did not boot to CM before installing the gapps, the CM zip could also be the problem. What version was that?
[Nook Color General] jacobrosen2:
my apologies: gapps-jb-20130813-signed.zip, cm-10.2.1-encore.zip, generic-sdcard-v1.3-CM7-9-10-10.1-10.2-11-largest-Rev8b.img
[Nook Color General] leapinlar:
Those are all the correct version. Something must have just glitched during the install. You are on the right track to just start over. You might try formatting the SD with SDFormatter free on the web before attempting to set up the SD again. I think they have a Mac version.
[Nook Color General] mlegs:
Does the nook color device boot automatically from SD card if it detects it ? Or do I have to do something for that?

.. How exactly do I boot from SD ?

I forgot to say that after an attempt to install MROM 7, my nook color won't even load the recovery :( it just shows a green logo of cyanogenmod before it directly tries to load the broken rom, no matter what I press. Can I boot from SD in my case?

LATER EDIT: Ok, I figured out that it automatically uses the bootable sd once it detects it :) Thank you so much for this thread ...

I'm having another question now: Will my device run laggy if I use the bootable SD operating system? taking in consideration that there are different speeds when reading from sd rather than internal memory .. ?

Thank you
[Nook Color General] leapinlar:
If you have a decent quality SD (SanDisk class 4), there should be little difference using an SD.
[Nook Color General] mlegs:
Thank you, leapinlar

I made my sd card bootable, but it only has 300 MB now.; I'd like to revert it to unbootable mode and to have 16 gb back, How can I do that?
[Nook Color General] leapinlar:
Get SDFormatter free on the web and use that to restore to full size.
[Nook Color General] leapinlar:
Just curious, where did you buy yours? I got mine on Amazon in a generic package. It looked like it was mailed from Sandisk, but I worried that it was counterfeit. It could just be a new manufactoring process by Sandisk, but I still wonder. I bought two and they both acted the same. I put one in my Galaxy Tab as sdcard and it works great.
[Nook Color General] moosehaed:
A question?

I am running cm9 9/4/2012 build on the nook color.

It has been freezing on me more and more frequently. I want to update to a newer build.

Is there a way to update other then reformatting the sd card and starting over from scratch?

Thanks
[Nook Color General] Mr-Glass:
leapinlar - I did in fact get mine thru Amazon as well - I believe it was listed as bulk packaged.. I am pretty sure mine is fake - I ran the h2testw_1.4 and it came back as only almost a 4gb writable card and the write speeds were in the class 2 speed.. I bought it quite awhile ago and had it around until needed - I probably should have checked it as soon as I received it.. Glad to hear yours is working with your Galaxy Tab - I am not sure I am going to trust this one for anything..

Edit: lepinlar - I contacted Sandisk and they confirmed that my card was a "discard" card.. I actually got a really nice cust. service rep who said they would replace it anyway.. On another note - I asked my girl to pick me up another while she was at Costco and she came home with a Sandisk Ultra 32gb class 10 - so I tried it anyway and it worked fine.. go figure.. not bad at Costco for 23 bucks.. kudos
[Nook Color General] leapinlar:
Yes there is, but it takes a little work.

1. Get Titanium Backup and use it to backup your installed apps. It will store them on your media partition (sdcard). Save those backup files to restore your installed apps later.

2. Go to my tips thread linked in my signature and look at item B5 in the second post of that thread. Install the Alternate CWM modified for SD.

3. Use that Alternate CWM to do a nandroid backup of the current SD installation. That will also save the backup to your sdcard. I had you do this in case after you have tried all the below stuff and it has not worked for you, you can return to your current installation of CM9.

4. I just added two zips to my tips thread (NookColor-verygreenSD-format-system.zip and ...data.zip). They will wipe/format system and data on the SD. Download those zips and flash them with the Alternate CWM. That will clear system and data in preparation of installing CM10. I don't trust the built in wipes/formats in CWM, they seem to be unreliable sometimes. But it is probably OK to use it to wipe cache. That is not as critical.

5. Now install CM10 and gapps as I described in the first post of this thread for updating an existing installation (copy to boot partition, boot to SD recovery, etc).

6. Hopefully this all works and you can register your gapps again. If it does, install TB and restore your previous apps.

7. If the CM10 installation fails and you want to return to CM9, just use the Alternate CWM to restore your nandroid backup.

This should work. I've done it to install CM10 (10/26 - unknown_world's version) over CM10 Alpha 1. That is why I made those format zips for myself.

EDIT: I just reread your post. You said to update to a newer build. Since there is not a newer build of CM9 later than 9/04, I assumed you meant go to CM10. You only have to do all this above if going from CM9 to CM10. It needs a full wipe between installations. If you can find a newer build of CM9, you can update much more easily. Just do what I said in my first post for updating. Same is true if going to a new version of CM10 over an older CM10. Just update without wipes.

EDIT 2: I just installed CM10 Beta 1 directly over Alpha 1 using the update method I talked about in the first post. No wiping of any kind and it worked perfectly.

Installed CM10 on SD, hands at CM splash screen after reboot

Installed CM10 beta2 on SD card using the modified rev5 image. Install went slow. After everything was installed, saw app tray, made settings changes, set CPU govenor to "ondemand', rebooted. Now it loops forever on CM splash screen. This is not my first install with CM. I have 2 NCs, both on CM7 - one on emmc and one on SD with stock emmc. I will try CM9 to see if I duplicate the loop on CM splash screen. If so, could it be a bad SD card? It is the same SD card (8gb) I used to image CM7 before deciding to install to emmc. I just reimaged it for CM10 beta2.

Installed CM10 beta4 on SD card using rev5 image. Install went fast. No more looping on CM splash screen. Wifi downloads faster. Using a 16g Sandisk class4 (used to be a data storage card for my emmc CM7 NC). Very responsive and smooth.
[Nook Color General] leapinlar:
I would have suspected a bad SD but you said it worked fine before. So I think we can rule that out. There is an intermittent bug in CM10 where it will not reboot. Other users have gotten out of it by clearing the cache. Fortunately for SD users, the SD install shares the cache partition on emmc with the ROM there. There are two ways to clear it. If you have a rooted ROM on emmc, you can boot to that and use root explorer to delete the /cache/dalvik-cache folder. Or you can use CWM or TWRP recovery to clear it. If you don't have CWM or TWRP, you can get the latest CWM on a bootable SD on my tips thread linked in my signature. Users have found that it will reboot after clearing the cache.
[Nook Color General] hwong96:
Installed CM9 on same SD card CM10 looping on splash screen

I installed CM9 latest version on the same SD card that was looping on the splash screen when CM10 beta2 was installed. CM9 boots up fine. I am restoring my apps now in CM9. Will be dual booting CM7/CM9. I may install CM10 as an altImage in the near future to help with debugging.
[Nook Color General] alphabets:
i appreciate all the hard work, install went perfect both times (alpha install and now beta 2).

I am having one issue though.....it is extremely laggy. almost unusable after a while. not sure if this could be an sd issue, but im using a class 4 kingston 8gb.

i like to be able to boot from the sd because my wife likes to use the stock nook from time to time and we just pop the sd in and out.

but with this lag, im wondering if i just need to flash CM internally.

any tips would be appreciated! thanks!
[Nook Color General] leapinlar:
It could be the SD. I don't know about Kingston, but I just used a PNY class 4 and it was so laggy that it was totally unusable. If your wife likes the stock, get a Sandisk and you both will be happy.
[Nook Color General] alphabets:
do you think it could be the class as well as the brand? don't remember having this much lag on CM7 through the sd before and it was the same card.
[Nook Color General] leapinlar:
If the card was working fine on CM7, I doubt the problem is the card.

BTW, if your wife likes stock, I just posted a way on my tips thread where you can now put stock on SD. That way you can have emmc for yourself and make her use the SD. LOL.
[Nook Color General] alphabets:
oh, sweet! i was looking into that forever ago...that might be the trick for me. thanks man!
[Nook Color General] wwu123:
Three separate SD cards, three different card reader/writers, CM10 gets stuck booting up at the spinning CyanogenMod circle... CM9 worked fine with these instructions though. Tried clearing the cache using Root Explorer from CM7 running on the internal emmc, still didn't help the CM10 get booted up.

.
[Nook Color General] leapinlar:
Clearing the cache with root explorer is not the same as doing it with CWM. I think that just clears the cache for each app and not the dalvik cache. (Edit: strike that, i was thinking Titanium Backup, not root explorer). They are different things. Since you started with a clean SD, you do not have to worry about the cache on /data. But there may be a problem with the one on emmc, which the SD shares with emmc. Boot to emmc and go to /cache/dalvik-cache with root explorer and delete all the files there (edit: I think that is what you already did). Then immediately try to boot to your new CM10 rom on SD. See if that helps.

Edit: given that you already did that, I don't know what to say other than I think one, I think B1, had a bug where it would not always boot right. Sorry if I caused confusion with my earlier comment.

Flawless installation, running CM10b2 now, and loving it. Charges fast, great battery life, smooth performance, and the only thing missing is USB support. Thanks to the dev team for all the hard work!
[Nook Color General] leapinlar:
What kind of USB support are you looking for? USB mass storage works great. Are you meaning something else?

I've installed and have been running cm10 alpha for a while. I'm excited to get my hands on the beta build now. However, I'm wondering which steps I'm going to have to repeat in order order to successfully install the beta build. Will I have to reinstall Gapps, or can I just flash the ROM and call it a day? How Many things will I have to wipe? I'm also wondering how the steps will change in future builds.

As for the above quoted text, I believe he's talking about OTG support. Using a mouse on my 7inch tablet is surprisingly awesome. It's something I miss from cm7 (not complaining though, just excited about getting it back.)

[Nook Color General] leapinlar:
You should be able to just put the zip in the boot partition and boot to SD recovery. Worked for me. No other wiping. Should not have to re-install gapps, but might have to.

I have no idea what you are talking about. You might get better results asking that question on the CM10 general discussion thread.

Worked great until the battery went out

I followed the directions, used cm-10.2.1-encore, gapps-jb-20130813-signed, and -sdcard-v1.3-CM7-9-10-10.1-10.2-11-largest-Rev8b. Everything was working perfectly until the battery started to go dead. I pluged the charger in and the screen went black and had what looked like an outline of an sd card with a plug and lightening bolt symbol below it. The nook will boot up fine into the stock os with the sd card taken out but will not turn on with the card in. How do I fix this?
[Nook Color General] leapinlar:
I have never heard of this before. I would suspect a bad SD, somehow drawing too much current.
[Nook Color General] SirCasey:
Update: I tried from 2 different PCs, borrowed a different SD card reader from a friend, still using the 2 SD cards, a 16GB class 10 and 8GB class 4.

Also used SDformatter on them.

Never got my NC to boot to one of the images.

Found the files from back when I loaded CM7 by Team B, flashed that image to either SD card and it boots right up into CM7. So I feel like my hardware is fine, I must be missing something else.
[Nook Color General] leapinlar:
Team B is a Nook Tablet team. You have a Nook Tablet not a Nook Color. You are in the wrong forum.

It's not working and I don't know why

I'm using gapps-jb-20130813-signed, cm-10.2.1-encore, and generic-sdcard-v1.3-CM7-9-10-10.1-10.2-11-largest-Rev8b.

I followed the guide how to format the SD and imaging with Win32DiskImager and transfer the files.

I'm using SD 4GB class 4, Kingston.

Maybe it's because I updated my nook to 1.4.3 yesterday?

Do I need to use different files?

Your help is much appreciated!
[Nook Color General] leapinlar:
You don't say what your problem is. Is it not booting to the SD? If it is not, are you sure you have a Nook Color rather than a Nook Tablet.

my brand Nook Color converting to CM10.2

I am a newbie here and am not too familiar with Android os.

However, I successfully installed CM10.2 on a SD card (thanks to a very well-done video by Everything4Tech1). I am not happy with the performance of theconverted NooK color. It is slow and the Apps just hang up with error message saying the app has stopped working or not responding with choices to wait or close.

I want to know from someone if there is anything I need to do in settings.

I would like to install CM11 on emmc and the procedure requires me to install CWR 6.0.4.7 I followed the video of the same guy, I am getting NOOK stock recovery. Could some body explain how can I get from CM10.2 on SD card to CM11 emmc, so that I can get a decent performance of browsing and other apps.

Thanks for you help

I am Getting Very Confused!

You need to start over by either using a new SD or formatting your existing SD with SDFormatter using the overwrite and size adjustment options on. CM11 is not compatible with the old CM7 setup.

GAPPS on CM11

This is my first post, and I feel I've missed something major. I have previously successfully installed 10.2.1 and several before that. Now I wiped the 32GB SD card and installed the rev8b image, then cm-11-20140210-SNAPSHOT-M3-encore.zip, and that works. I can get into my IMAP at school and also Google mail. But when I install gapps-kk-20140105-signed.zip I get a status 7 error and it fails. I can't get the Google Play Store etc, so I'm stuck.

The goal for updating is to run Netflix. I had that running on 10.2.1, but an upgrade broke it.

I'ld be very grateful for a pointer to the solution. Thanks for your great instructions that have gotten me this far.
[Nook Color General] leapinlar:
How are you trying to install the gapps? That status 7 error sounds like a CWM error. You should not be using CWM to install. You should copy it to the boot partition and boot to SD recovery and let the script installer install it just like you did the CM11 zip.
[Nook Color General] mbudd:
gapps install status 7 again

I have used the instructions here http://xdaforums.com/showthread.php?t=1941858 with success up until CM11. I have installed the alternate boot option there. I first copied the gapps to the boot partition just like I did with CM11, but that seems not to work, and I have also tried the alternate boot option "choose zip from sdcard" - this is where I can see the error - Status 7. It takes a while - like it is unzipping the file first, then (Status 7) Installation aborted. appears. It says CWM-based Recovery v6.0.1.2 for SD.

Is this what you meant?
[Nook Color General] leapinlar:
CM11 and the matching gapps require a version of CWM that is 6045 or higher. The alternate CWMs are older than that. So you need to use the old method of copying the gapps zip to the boot partition and booting to the SD recovery, which is the script installer. Is that what you said you tried? How did it not work?

Booting gapps

I just went back and redid everything including the dd of the .img file. I watched closer as things sped by on the initial load. The system installed, then gapps. But there were several chown errors like things were not there that it was expecting. Not sure about that. They were in system. Gapps install was less than a screen long. It seems it should be longer.

When it shutdown and I restarted, it asked the normal questions about logging in to Cyanogenmod, which I did, When it got to the Location settings I get a popup "Unfortunately, Google Contacts Sync has stopped. I ok that and continue on and it gives me the Welcome! And when it comes to the main desktop the Google search on upper left is truncated. I have the gmail icon and it works. I have 17 apps, but none of them are Google Play. After I set up one email account it says Trebuchet has stopped.

So am I not doing something right? I think I need Google Play.

Incidently, all this was after trying to install uNooter using the instructions on the CyanogenMod website, dding the .zip file instead of the unzipped .img file (oops) and now it just gives me a upside down U screen forever unless I have the SD card installed. Fortunately, it will still boot from SD. So I need to find how to fix my internal SD now.
