Been messing with this all day. Currently I boot CWM from the sdcard, flash a CM10 rom, do a factory reset and remove the sdcard and reboot. The NC boots fine but when I reboot into recovery or shut down and power up into recovery the NC locks up at Cyanoboot splash screen saying

Loading....

. Once the NC enters the Recovery mode the only way to get past the Cyanoboot splash screen is to put the CWM sdcard in and repeat your procedure.

Seems the problem is that I normally have Recovery load from the emmc and once the NC tries to load from there it locks up at Cyanoboot.

BTW, I'm posting this the eve of the holiday in the US just so I won't forget what I experienced. My memory isn't what it used to be!
[Nook Color General] leapinlar:
Well it depends on what versions you are running. You say CM10, but I think you mean CM10.1 or CM10.2, they are different and operate differently. And what recovery version are you running? You did put a custom recovery on internal didn't you? It does not come with the ROM.
[Nook Color General] unibroker:
cm-10.1.3-encore.zip is what I had flashed. I currently have TWRP 2.3 on internal.

edit: I have used different versions of TWRP for over a year. While addressing this problem I used your TWRP link but had better luck with the CWM route. I am thinking of just putting that on internal as you suggested for my CM11 build.
[Nook Color General] leapinlar:
Well, you need to something to update the recovery. That is why it is stuck on Loading....
[Nook Color General] unibroker:
I've gone to the TWRP website and following the guide to install TWRP on emmc. I get stuck after the first instruction

adb shell busybox remount / -o rw,remount

with

remount: applet not found

. Most of what I've read suggests reinstalling busybox. Is there an easier way to get TWRP onto emmc or to repair the TWRP that is already there but incapacitated?

edit: Forgive me. I'm rereading your tips and feel my answer is in there.
[Nook Color General] unibroker:
I pushed your NookColor-emmc-stockrecovery.zip on to the CWMbootableSDcard. Shut down and booted into recovery on the CWM sdcard. I then flashed NookColor-emmc-stockrecovery.zip and then shutdown. When I booted back up Cyanoboot again stuck

Loading.................

Apparently I don't have the concept right.
[Nook Color General] leapinlar:
Something is wrong with your boot partition. Go to my NC partition repair thread and flash my repair zips. That will wipe everything, including your broken internal TWRP. Then you can try flashing your CM10.1 again and this time install CWM (6045) to internal instead of TWRP. Once you get that all working, you can try TWRP again if you want.

Edit: Wait! I think I know what is wrong. You keep restoring your backup. That backup has a borked recovery and it overwrites the good one. Don't restore that backup anymore.
[Nook Color General] unibroker:
I haven't been able to even attempt to restore backup since yesterday because I recall after trying one time the last thing it outputed was something about rm -rf boot! I didn't enter that command. Why would it do that?
[Nook Color General] leapinlar:
That's what I was saying that your /boot partition is messed up. That is saying it can't erase the files there. I think you definitely need to do the partition repair and format.
[Nook Color General] unibroker:
Everything went smoothly this evening. I am now running CM11 and have CWM6 on internal memory after performing your partition repair. At this point would you suggest that I not attempt to restore my backup? If you do I won't flash TWRP seeing as how they seem to have abandoned the Nook.
[Nook Color General] leapinlar:
you can try putting your old 2.3 TWRP back on and try the restore. If it messes up again, at least you know how to fix it now. But you will need that CWM every time you want to flash a CM11.
[Nook Color General] flushdaddy:
I'm trying to upgrade my Nook Color from CM7 to CM10 and get stuck at the loading circles. I have the rom installed in the EMMC memory.I wiped the data/cache/Davlik and fixed permitions. Using CWM v6.0.1.2. Don't know what im doing wrong. I put the rom and the gapps on the sd card and intall them form there. First wipe data/cache, install the rom, wipe data/cache/davlik reboot and get stuck. I used this rom cm-10.2-20131201-NIGHTLY-encore.zip and this gapps gapps-jb-20130813-signed.zip .:confused:
[Nook Color General] leapinlar:
How long have you waited with the circling logo? Sometimes the first boot takes a very long time.
[Nook Color General] flushdaddy:
I have left them overnight twice already.

---------- Post added at 08:55 PM ---------- Previous post was at 08:36 PM ----------

The thing is that I can flash CM7 and CM9 with no problem. It's with CM10(any of them) that I have that issue.
[Nook Color General] unibroker:
Try it without the second wipe sequence prior to the gapps flash. I assume you're booting up after flashing the rom; rebooting into recovery to flash gapps.
[Nook Color General] leapinlar:
Try formatting /system and factory resetting. No other wiping. Then flash just the CM10 zip (not gapps yet). See if that will boot. If it does, you can then flash gapps.
[Nook Color General] flushdaddy:
I'm going to try it using twrp 2.3.1.0 as the internal recovery. To see if that works
[Nook Color General] flushdaddy:
It's been rotating for an hour now. I guess its safe to say it's still stuck. I'm going to shut it down.
[Nook Color General] leapinlar:
That was with wiping /system and only the CM zip?
[Nook Color General] flushdaddy:
Yes.
[Nook Color General] flushdaddy:
I tried your partition repair guide, installed stock rom with stock recovery, went back to cm10, still nothing. Don't know what can be causing it not to boot.
[Nook Color General] flushdaddy:
Something intresting... I wipe the davlik cache and the regular cache and rebooted. It showed life since it went to the Android is upgrading creen, but after upgrading all apps, it got stucked again. I left it in the morning "upgrading", after work it was still "starting apps"
[Nook Color General] leapinlar:
And the stock worked fine after reinstalling it? It still sounds like partition problems to me.
[Nook Color General] Frustrated1:
Hello. I don't mean to hijack this thread but I'm having trouble with a Nook Color that I bought used. Looking in settings I see it's running Android version 4.1.2, Kernel version 3.0.8+, CyanogenMod version 10-20121119-UNOFFICIAL-, ParanoidAndroid version 2.55. I want to restore it to factory settings. I tried the 3 finger restore several times but it did not work. What is the easiest way to do this?

Thank you in advance
[Nook Color General] leapinlar:
The three finger salute only works if you have stock recovery still installed.

Make a bootable CWM SD per item A10 in the OP and then flash a stock ROM per item A15.
[Nook Color General] Frustrated1:
Please forgive me. I'm not very good when it comes to this type of thing. You may have to walk me through it at the preschool level.

1) I set up the SD card per A 10. After doing that should I then load the 1.4.3 zip onto the SD card before putting it into the tablet?

2) Should I load the unzipped 1.4.3 zip file onto the SD or should I unzip it and load a specific portion?

3) When I put the SD into the tablet what do I do after turning the power on? What should I see happening?

Thank you for your patience
[Nook Color General] leapinlar:
1. Yes.

2. Leave zipped.

3. It should boot to CWM. Then choose install zip from SD, choose zip from external SD. And install it. Follow rest of instructions in A15.

Update using TWRP v2.3.1.0

This evening I thought I'd flash TWRP and restore the last backup I made. After restoring system and data the output read

using rm -rf '/boot'
Restoring boot
Boot done (0 seconds)

Rather than hit 'Reboot' I decided to restore the other backup I had. It ended with the same output. I hit 'Reboot' and once again my NC is "dead". I'll go through the process for repairing emmc and flashing cwm but sure would like to know what is going on with TWRP for it to perform this destructive process on the boot partition.

Battery drainage, upgrading apps, ...

Leapinlar,

I really enjoy reading your "tips & tricks" post(s) and I thank you for the info. It's been most helpful.

I have a couple questions for you, or perhaps to Steven676 regarding the CM10.1.3.2.

I have also followed your thread for quite some time and have a CM7 installed on one of my 8g SD cards (sandisk). It has recently choked up on me and I can't erase or delete anything, I can't add anything to the boot sector to restore anything etc., and every time I try to open certain apps, it gives me an FC and I can no longer it.

So, I did the next best thing and installed CM10.1.3.2 on another SD card (sandisk) (I'm still running stock B&N on my color, unrooted).

First thing I've noticed is the battery drainage. It's dropping faster than I can blink. I have nothing running, or perhaps best described as a fresh boot. No internet, no gps, screen is dimmed. However, I have not wiped the Dalvik as this is a new SD card. Should I have done a wipe?

Also, does your CWM 6.0.1.2 do a battery assessment reset? And should I reset my battery stats as this is a new card/new OS?

Second question I think pertains more to Steven676 but perhaps you can answer this as well; When I do use this CM10.1.3.2, every time I boot up the NC after putting in the SD card, I get the circled display, then I get a message "upgrading apps ## of 81". Is this suppose to do an upgrade of the apps every time I turn on the NC? Or do I have something gone awry with the install? The OS eventually finishes it's upgrading of the apps and I have full access to everything and it works well, but I am curious about this upgrading apps message every time I boot the NC.

Thank you again for your time & effort in working with the NC.
[Nook Color General] leapinlar:
I can answer the second one easier than the first. It is your system dalvik cache updating. The SD install shares the /cache partition with the emmc. So each time you boot between emmc and SD, it must rebuild the system dalvik cache. If you look in my my tips and read item B3 (toward the end), you will see a trick to prevent this.

I don't know the answer to the battery drainage issue in CM10.1.3.2. Better to ask in that thread. Wiping dalvik would not have helped.

And your original SD must have turned read only. That happens sometimes and is not recoverable.
[Nook Color General] Hangman_:
K, now that I know that the system dalvik cache is updating, I know what I can do to prevent the continuous upgrading of apps. Thank you.

So, if the original SD has turned read only, can it be formatted and reused or is it plain toast?

Thank you again.
[Nook Color General] leapinlar:
toast.
[Nook Color General] lorddunlow:
So in my excitement to flash CM11, I accidentally flashed eyeballer's TWRP alternate boot instead the normal boot. I had a dual partition on the EMMC with stock on alternate and CM10.1 on primary using Taosaur's old guide, so the TWRP took the place of my Stock ROM.

Is my stock ROM completely overwritten? Any quick fix?

If no way to easily fix, I'll probably just repartition with a single boot setup, as I don't see me using the stock much from this point on (as I have a Nook HD + now).

CM11 and the TWRP work great, though!
[Nook Color General] leapinlar:
I don't think there is a quick fix. I suggest you start over fresh.
[Nook Color General] micl9:
LeapinLar you are awesome.

Had the boot loop to recovery issue - repaired partition 2 with your files and SD image and now good to go.

Black screen after cyanoboot loading

leapinlar, hope all is well. I'm trying to get a nook color going for my daughter. I was going from 7.2 to 10.2.1 and everything seemed to go well but after the cyanoboot screen says loading for about 3 seconds, the screen goes blank. I can see there is still some illumination on the screen. I have tried the CWM ver 6 recovery boot from sd but I get the same result. I also tried the repair tool for partition 2 and still the same thing. Where should I go from here. The 7.2 was installed on the emmc, I tried to install from a bootable sd image rev 8b to overwrite but I get the same blank screen after rebooting.

Unroot a Nook Color

Hi Leapinlar,

I am probably doing this the wrong way but could not figure any other way to ask the question. I have a rooted Nook Color with CM7. I want to unroot it and give it to my granddaughter as a plain old Nook ereader. I have tried following some of the described ways to do the unroot but most of the links to the files seem to be outdated or no longer in existence. Can you point me in the right direction for a set of accurate instructions to unroot this device ?

Thanks,

Randy B
[Nook Color General] leapinlar:
Look at my section A15.
[Nook Color General] iluv2Learn:
Unroot a Nook Color

Hi Leapinlar,

Okay, I read A15, I have your 1.4.3 zip, 6.0.1.2 CWM, and your 5.6.7 zip on my desktop. I forgot to mention initially that I am somewhat a NOOB on this Android stuff. Can you create a roadmap of the steps I need to do to get back to the unrooted Nook Color.

Many Thanks,

Randy B.
[Nook Color General] leapinlar:
Make the 6012 bootable CWM per item A10. Copy the 1.4.3 and 567 format zips to the card. Then boot to CWM and install the 1.4.3 stock zip and the 567 format zip with it.

unroot Nook Color

Hi leapinlar,

Did as you suggested .. success. Was able to get the Nook Color to load an SD with a different ROM on it. But when I remove that ROM and turn on the Nook Color I get a "Read Forever" message and then the screen changes to an "N" with some verbiage at the bottom about Adobe Systems. And freezes there.

I will try to use your SD card to load the downloaded 1.4.3 software from B&N unless you have a different solution. My ultimate goal is a dual-boot system .. The B&N system as one choice and the custom ROM as a second choice.

Thanks for all your help .. This is starting to be fun for this old retiree .. :))

Randy B.
[Nook Color General] leapinlar:
You cannot flash the 1.4.3 downloaded from B&N with my SD. You must use the 1.4.3 from my thread. And did you install the 567 format zip successfully before you removed the SD and rebooted?
[Nook Color General] iluv2Learn:
Unroot Nook Color

Hi Leapinlar,

OK, Yes, Yes, And Yes.

As previously stated, I created the CWM with your routine. I then loaded your 1.4.3. I then loaded your 567 routine. They were copied to the SD as .zip files. I did not expand them, I left them as .zip files. I even changed the order of putting the 1.4.3 and the 567 files into the Nook.. Still same result.

Should I being clearing any of the Dalvik cache files ?

I have searched for similar instances of what I am seeing, but have not found anything like what I am seeing.

Thanks again for your help,

Randy B.
[Nook Color General] leapinlar:
No you do not have to clear dalvik. That 567 zip formats everything. Are the zips saying they installed successfully with no error messages? And you must run the 567 format zip before you flash the 143 zip or it is wiped out.

Unable to boot into SD recovery

Hi LeapinLar,

First off, Thanks so much for the great guide. I was an early adopter of the Nook Color and used to run CM nightlies back when CM7 first rolled out. I turned my first NC into a tablet for my 5 year old to play games in the car. I recently acquired another NC and want to do the same, turn it into a tablet for my 3 year old to watch videos and play games on road trips (as opposed to giving him my really nice Android Tablet).

The new tablet will not get past the "Read Forever" boot splash screen with a normal boot. I really don't care about the stock ROM and was going to flash Mirage over it. So using your tips, I followed the instruction outlined and set up a bootable CWM SD card (which I've done a dozen times or so). The NC startup with the Cyanoboot bootloader, but will just stay at "Loading". Trying to boot into SD card recovery or any other option just causes it to sit at "loading". I'm quite familiar with both Clockworkmod recovery and TWRP recovery as I was Moto Droid X rom flasher and now a Galaxy Nexus rom flasher (I just can't stay with one rom too long!)

I Tried the older 5.5.0.4 CWM image as well as the TWRP image and even an older 1gb clockwork3.2.0.1 card made by Eyeballer. I also tried using a different memory card to make sure it wasn't a bad SD card.

All result in the same "loading". I've tried the 8 failed boots three times. Turning on the NC while holding the N button to enter recovery also does not work. At this point I'm thinking there may be a hardware issue with the NC, but I'm not beyond using ADB if I can track down the image files (they are so old most links are dead) for boot and system.

I can't even attempt a repair to the partitioning since I can't boot into sd recovery. Any suggestions would be appreciated. Again, thanks for your great guides!

Dr.Bones
[Nook Color General] leapinlar:
Did you follow the procedure for 8 failed boot from this thread?

And holding n while booting only works if you have CM installed.

And just trying one other SD is not enough. Read my section A9 about how finicky the NC is to boot from SD. Try the tricks mentioned about how to burn, etc.
[Nook Color General] drbones:
Ok, So I tried the 8 failed boots 2 more times, no luck. I did stumble upon a img file of the demo honeycomb rom which actually booted and I'm playing with it right now. The question is now that I have a live OS, what I can I do to install a recovery with the honeycomb rom?

I'll try a couple of different memory cards if I can scrape a couple up tomorrow. In addition, I used three different computer and two different img burners to try different options.

I'm hopeful since honeycomb booted!

resize internal memory

Hello leapinlar, I have read your guide & would like to ask you a question about repartitioning my nook color.Recently I was able to repartition my samsung s2 galaxy phone to have a more satisfying division between the device memory and the usb storage.Can the same be done to my nook color without bricking my device? Also will the repartition let me use the whole 8gb memory capacity it has?Thank you for your time & patience.
[Nook Color General] leapinlar:
Yes you can repartition it. But it already uses the whole 8GB, it just can be divided differently. See Dean Gibson's thread here:

Thank you leapinlar for your help :) Do you think it would be possible in your opinion to divide the 6gb size into a 4GB /data - 2GB /media format??
[Nook Color General] leapinlar:
Yes, but it takes some skill. It would be best to just use Dean's 5/1 scheme. Just use an SD if you want more media.
[Nook Color General] drbones:
So I've tried 3 different sd cards and 4 different sd card readers. The farthest I've been able to make it is to boot into a recovery sd using an ext formatted card mentioned in this post: http://xdaforums.com/showthread.php?t=959240, I had to find the actual image file by searching the file name and found an image on root monster pack's site here

I can boot into recovery, but any image I write does not boot. I still can not boot from SD card except from the honeycomb img and the ext4 formatted card. I tried partition recovery and writing a whole new rom, but I still can't get past the splash screen.

Any suggestions are appreciated.

Want to go back to B&N Stock

I have rooted my nook color to CM 11 and had problems with the keyboard working then I fixed that and then google play wouldn't open, so I had read that CM 7.2 was best due to NC being slow. I rooted to that and had issues with keyboard again. I decided to just go back to the regular B&N Stock, I flashed the 'update-nc-stock-1.2-signed.zip'. Now it starts to boot with the 'Read Forever' then goes to the Nook symbol but won't go anywhere from there.

If anyone can help I would appreciate it. If you provide me with a zip can you provide me with the md5? I don't know how to get them besides using techerrata. Thanks so much in advance

The keyboard issue is usually because you used the wrong version of gapps for the version of CM you are running.

Help me revert to CM7

Good day guys

So much useful stuff in this thread. Keep it going!!:o

I rooted my NC and installed CM-7 which was working perfectly but stupidly enough I was tempted to upgrade it to CM 11 and installed a different kernel for that and that was when the trouble started.

CM11 I soon realized is too heavy and resource consuming for the little device and has made it terribly slow.

I tried reverting back to CM7; everything seemed to go OK but : blank screen.

Eventually I managed to try another kernel and revert to CM 10 but the tablet is still so slow that I cannot work with it.

I'm still unable to roll back to CM7; the blank screen after seemingly successful installation persists.

Can anyone help me please?

Here are the current details :

Android version: 4.3.1

Kernel version: 3.0.8-g080f0e5 build01@cyanogenmod #1 Fri Jan 31 21:16: 42 PST 2014
