Several users have complained that they get blank screens and cannot flash new roms to their Nook Color. And sometimes they end up in a recovery bootloop where it will do nothing but boot to recovery no matter what they choose in the boot menu. Sometimes this is due to corrupted partitions on internal memory.
DizzyDen has prepared some .img files that can be burned to emmc to repair some of these issues, and they work well. But some of the files are very large and it takes a little knowledge of adb commands on the part of the users. And some users cannot get adb working on their machines. So I started investigating other solutions, and I have made some tools that work that I hope are user friendly.
Dean Gibson has a thread that describes how to repartition emmc to set the partition sizes for data and media to the user's preference. He repartitions partitions p6 (data), p7 (cache) and p8 (media). In studying his zip, I figured out how to make his tool repair partitions p4 (extended), p5 (system), p6 (data), p7 (cache), and p8 (media). And I was able to add additional commands to also repair partition p1 (boot). I asked Dean's permission to post his tools as modified by me and he agreed. Thanks Dean!
So that takes care of partitions 1, 4, 5, 6, 7, and 8.
Partitions 2 and 3 are very special and one must be very careful with them. Partition 2 is 'rom', which holds information that is specific to the user's device (serial number, etc.), and it is used by the system to set flags for deciding whether to boot to recovery or not and set the boot count that is used to decide whether to do a reset to factory conditions (8 failed boots). Partition 3 is 'factory' and holds the factory.zip file used by the 8 failed boot reset (if you want to learn more about the 8 failed boot reset, go to my tips thread linked in my signature). It also holds a backup of the device information in partition 2. So it is possible to repair partition 2 if partition 3 is still intact.
A few users have somehow managed to flash Nook Tablet ROMs to their Nook Colors and really messed up partition 4. (Edit: and now I know how it happened, some idiot recommended that they remove the first line of the updater script. NEVER do that! That line is a safety check to make sure you are flashing to the right device. You can also defeat the safety check by using an old CWM that has the toggle, 'disable asserts'. Never do that either.) And since partition 4 is the extended partition that holds partitions 5, 6, 7, and 8, they get messed up too. To repair those partitions along with partition 1, use CWM recovery to flash the two zips attached below. Be warned that everything in emmc media (p8) will be wiped out, so you may want to back that up first if you still can. The first zip to flash is 'NookColor-emmc-repair-partitions-1-4-5-6-7-8.zip'. It will recreate those partitions on emmc. As soon as you have sucessfully flashed that zip, you must reboot the Nook Color back to CWM so that the updated partition table is read by CWM. Then you need to flash 'NookColor-emmc-format-partitions-5-6-7-8.zip' (partitions 1 and 4 do not need formatting). It will format the newly created partitions to the correct structure. Now you can use CWM to restore an earlier nandroid backup or flash your favorite ROM (including stock, get version 1.4.3 that I have modified to be flashable with CWM here, or DizzyDen has posted some excellent 1.4.1 stock ROMs here). If you are going to flash a stock ROM, you must be sure to use the format zip or the stock ROM will not boot properly.
If you are in a recovery bootloop, the first thing I recommend trying is to use my CWM version 5.5.0.4 bootable SD that is discussed in my tips thread linked in my signature and has been modified to help get out of some kinds of recovery flag bootloops. If you are in a recovery bootloop that just hangs, it may get you out of it after exiting my CWM with the 'reboot' command in the menu. But if you are still in the loop after doing that, it may be because your device info is missing or corrupted in partition 2. It will not boot to a ROM without this info. (Specifically, it needs a file in /rom/devconf named DeviceID. It is a text file with your 16 digit serial number in it followed by a line feed, 17 bytes.) Try flashing with CWM my 'NookColor-emmc-repair-partition-2.zip' attached to this post to recreate that info. But I recommend this as a last resort, since messing with that partition is risky. That zip will recreate the partition, reset the flags and copy your device specific information from partition 3. But your partition 3 must be intact for this to work. If it is not, the zip will abort and do nothing.
Additionally, for those that do not want to use CWM, I have made a bootable SD that has an older version of TWRP here. Newer versions of TWRP will return an error message when trying to flash these zips. It also has been modified to get you out of some kinds of bootloops.
Two points of information. First, I have included a temporary copy of CWM 5.5.0.4 on the boot partition of my repair so that if tries to reboot to emmc before you put a ROM on it, it goes to CWM. It will be removed as soon as you restore a backup or flash a ROM. Second, the new partition scheme created with my zip is for the original Nook Color's 1GB data and 5GB media. If you want one of the other schemes (5GB data/1GB media or 2GB data/4GB media) go to Dean Gibson's thread and flash his zips after you have repaired your system with mine. See his thread here.
I'm adding a little extra information about emmc partition structure for those interested. With any MBR disk there can be a maximum of four primary partitions. So to have more than four partitions the last primary partition is created as an extended partition so multiple logical partitions can be made inside it. The emmc structure is: p1 (boot, fat, primary), p2 (rom, fat, primary), p3 (factory, ext3, primary), p4 (extended, going from end of p3 to end of the disk), p5 (system, ext2, logical, inside the extended), p6 (data, ext3, logical, inside the extended), p7 (cache, ext3, logical, inside the extended) and p8 (media, fat, logical, inside the extended).
You save my nook color
Thank you so much. My serial number and other information were recovered successfully. Without those information I could not boot into any rom. If you cannot boot into ROM after following the first 2 steps, try recover partition 2. It works for me.

My nook has been stuck in a "will not boot" state for about a week. I could run CWM and cyanoboot, but when ever I tried to boot CM I would get stuck at the "loading..." screen. I tried loading both CM7 & CM9 but neither one would boot.
I ran both repair scripts, reloaded CM7.1 and success!
Thanks Leapinlar! :good:
THANK YOU!!!!!!
Right from my 1st install I couldn't get the bar at the bottom of the screen, which made using the Kindle app more than a little difficult. This finally cleared everything off so I could start with a clean slate, and BINGO! I know have the bottom bar on all the screens. I assume when I go in to the Kindle app it will be ok now also (I just have to format a 16gb microSD and put in the Nook Color 1st).
I can't thank you enough!!!!
Ugh! Tried this method too, and I still cannot get the nook to boot into CWR or CWM. I tried the 8 boots thing too, but I don't know if I ever did it right because I have cyanogen mod installed on emmc. Not sure how to repair the partition if I cannot even boot into anything that allows me to flash the zip to the chip. I thought it may be the sd, but the sd cards work on my other nook. I have now basically dissembled my nook color trying to find any other solution I wish I knew what happened in the first place.

Did you try my version of the CWM bootable SD card? It is on my tips thread and has been modified to boot in certain types of recovery bootloops. Unless you get CWM running you cannot flash things to internal memory. And depending on where in the boot process it hangs, you may not be able to get adb working to put things there either. And the 8 failed boots will not work unless you have stock recovery still on emmc.

Yup. Tried the card. I believe I replaced the emmc with cyanogenmod back in the day. Starts, goes to loading, turns black, then done. Cannot do anything after that. Bummer, sounds like it is actually toast.

If you can get adb working while it is sitting there black, you can push the stock recovery files to partition one. Then you may be able to do the 8 failed boots. You can extract the stock recovery files from my zip in my tips thread.

Worth a shot. Have nothing more to lose other than time. Maybe adb will work with you card in it. It didn't work with everything else I tried.
OMG OMG thank you soooo much for this thread , you saved my reading addict self from going insane ......
You've done a great job on collecting all of these useful things, especially for those who are stuck with their Nook Color boot looping. (I was once that guy) Dean helped me out with his data zips as well way back! Thanks for all this! :good: :victory:
Much thanks, leapinlar. Restored a nandroid with TWRP that was corrupted and lost my boot partition. I used your first 2 repair zips and I'm back in business. Your many contributions are greatly appreciated.

OMG! Thank you so much for putting this up! Back at the beginning of the year I was having problems with my NC not going into USB Mode and only showing a black arrow when trying to load books and following this finally fixed it. Great write-up and instructions, thanks for the hard work.
I've been trying to restore my NOOK for about 2 weeks and this post has gotten me the farthest but i'm stuck at the point where my nook will start up, the "Read Forever" splash screen will come up and then it attempts to recover the system since i see an greenish Android screen come up for a second and then i get an error screen saying "Install Failed" with an image of a nook with an exclamation point in it's screen. I'm assuming i've really messed the nook up but here is where I am.
I've reformatted the partitions using your 1-4,5,6,7,8 zip
Rebooted to recovery
Formatted partiions 5,6,7,8 with your zip
Flashed your 1.4.3 stock rom
At this point I can't get any further since it appears something else is wrong and i didn't want to attempt the reformatting of partition 2 without asking if there is anything else i should try. Any help would be appreciated.
Thanks

Oh, that is really bad news. That means your partition 3 is corrupted and there is no way to retrieve your device info, like serial number, etc. PM me and maybe I can help you get it partly working, but much of the device info is lost if that partition is truly corrupted.

During reboot it should automatically go to CWM because everything else is wiped. The boot menu only lets you make the first choice because that is all that is there, everything else is wiped. You need to continue to use the CWM to flash the format zip next. Then you can flash a ROM. If the CWM that pops up is not working, use the bootable CWM SD.

Thx for replied, the Nook just stock on loading and it won't let me do anything except for power up and down
I reverted from the dual poot through internal partitions.
The dualboot was set up via this topic.
http://forum.xda-developers.com/showthread.php?t=1275859
After that I ran the revert dual boot zip and then used the customer partition setup from this thread.
http://forum.xda-developers.com/showthread.php?t=1094371
Suddenly, I could only boot to cwm. No matter what boot option I would choose, cwm would load. It would let me flash roms but I could not boot into them. I eventually got around this by re-installing cwm using rom manager from a rom running on an sd card.
That created a new problem. Every time I tried to boot, it would not mount emmc. I tried installing the rom MiRaGe. This had the strange effect of mounting my sd card as emmc and my internal drive as my sdcard
I found this guide and tried to restore my partitions back to original
http://forum.xda-developers.com/showthread.php?p=25354258#post25354258
I am using the cwm from that thread as well. I am back to booting into a black screen no matter what rom I use.
Are there any suggestions on what I can do next?
Sounds like you have your partitions pretty messed up. Go to my partition repair thread linked in my signature and follow the guidance there, including doing the partition 2 repair. Do not forget to format the partitions immediately after the repair zip is run.
That swapping of emmc media and sdcard is a setting inside of CM7. It is intended for users who have no SD and want to use emmc media as sdcard.

Thank you for your help.
Here are the steps as I read it and the order in which I did it
1) Flash sd card with CWM-5.5.0.4-bootable_SD.zip
2) Copy NookColor-emmc-format-partitions-5-6-7-8.zip, NookColor-emmc-repair-partition-2.zip, and NookColor-emmc-repair-partitions-1-4-5-6-7-8.zip, and update-encore-cwm.5.5.0.4-emmc-racks.zip.
3) Boot into cwm from sd card
4) install zip "NookColor-emmc-repair-partitions-1-4-5-6-7-8.zip"
5) reboot system
6) install zip "Copy NookColor-emmc-format-partitions-5-6-7-8.zip"
7) reboot system
8) install "NookColor-emmc-repair-partition-2.zip" (This does report success)
9) reboot system
10) install "update-encore-cwm.5.5.0.4-emmc-racks.zip"
11) reboot into cwm
Now that I am boot into cmw (I took out the sd card before boot to make sure it installed properly,) I follow these steps
1) Install rom and gapps (encore_CM72-MiRaGe-09302012.zip) It reports sucess
2) Boot into black screen.
Can you tell me if I am missing a step or if I am doing one of the previous steps incorrect?
****edit - I seem to be able to install cm9.
I'll report back after testing it out.

You did everything right. You may have had a bad download of the mirage zip.
I was trying to install CM10 onto my Nook HD and I somehow screwed it up. I flash ROMS all the time on my MyTouch 4G and i am not a complete stranger to flashing, but I messed it up some how. Now the Nook HD will get past the Nook Banner. I tried a hard reset but it gets like 98% then shuts off. I can still insert an SD and access CWM but nothing will flash and i get this error when I try to do anything.
E: Can't mount /cache/recovery/command
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log
I made a backup on the internal SD but it says there are no files in recovery. I am at a loss. This is my first post I am hoping someone would have an idea.
Thanks
If you tried a hard reset, the first thing it does is format everything. That is why you no longer have a backup on internal memory. Never store backups on internal memory without copying them to SD or your PC for safekeeping. It is the first thing lost on a reset.
Those cache errors mean that the cache partition is not formatted. You need to boot to a CWM SD for stock and format /system, /cache and /data. Then flash the plain stock 2.0.0 stock ROM that I have linked in my HD/HD+ CWM thread. Then you can boot to it, let it update and register again.
Then you can start over with CM10 to SD. And when you said you tried to install it earlier, I hope you meant install to SD. It cannot be installed to internal memory.

I'm the same situation. The problem is that these partitions are physically gone.
How do we recreate them? It sounds like something that has to be done using adb, a disk partioning utility (fdisk maybe?) and the names of the devices that need to be created, and then marking /boot as boot.
I've tried to format /cache and the other partitions but it says they don't exist. This problem is also preventing me from installing images including the stock Nook HD software, too, which apparently needs these partitions to exist already.
Thanks in advance for any advice.

I will give you two clues, then do some research.
First to understand the HD/HD+ partition structure, go to my HD/HD+ Tips thread linked in my signature and read item 16.
Second, the HD/HD+ uses a GPT partition structure rather than the standard DOS MBR structure. You need to use gdisk instead of fdisk. Search the Nook Tablet forum to understand a little more about gdisk and GPT. The NT also uses it.

bricked my nook hd+
Hi guys, I'm a noob and yet I took a chance to upgrade my nook hd+ into CM 10.2. On the initial boot with CWM sd card, my nook recognized it right away. I followed "installing cyanogenmod 10.2(instead of 10.1) for dummies After much trouble I was able to "reboot system now". Now as I rebooted from the CWM 10.2 install, all I get is an initial boot with nook for a few seconds which flashes in and out then switches to the cyanogen universal bootloader after power button is pressed a number of times. Then much to my surprise it loaded the page EMMC CWM Based recovery v6.0.3.2. I pressed reboot system now but it didn't load CWM cyanogenmod but only loads nook's initial boot page, flashes same page in & out, then after pressing on the power button a number of times, would switch to the cyanogen universal bootloader, pressing the power button some more brings the screen to EMMC CWM Based recovery v6.0.3.2. The choices here are: 1. reboot system now, 2. install zip from sd card (CWM sd card is still inserted in nook hd+), 3. install zip from sideload, 4. wipe data/factory reset, 5. wipe cache partition, 6. backup and restore, 7. mount & storage, and 8. advanced. What should be done from here? PLEASE HELP. Thanks

Quick question leapinlar. Does the 8 failed boots hard reset also restore the /boot partition to stock given your recovery is stock and not cwm or other?

You need stock recovery still on internal memory for the 8 failed boot to work. But if it works, everything is completely back to stock, including /boot.

Hi, thanks for the quick response. Do you mean rebooting the nook hd+ without the CWM sd card? Yes, I've done this step to no avail. It would boot to the EMMC CWM based recovery v6.0.3.2. I've to be honest, whilst waiting for a response, I tried to remedy the situation by trying to install CWM 10.1 but the upgrade cannot get installed, then the android mascot just seemed to die (open chest with an exclamation point inside a red triangle). Does this mean it's irreparable?

As Sherip said, the CM10.2 is an SD install only. You should not have been following the Dummies guide for installing that. That is for installing to internal memory. You need to go to my HD/HD+ CWM thread linked in my signature and put stock recovery back on internal. I have a link to it in my item 5 in that thread. Then the device can successfully do an 8 failed boot to get back to stock.

Thanks. (sorry for being such a dummy) I tried flashing NookHDpus-emmc-...zip to my nook hd+ but this is the response I get each time I try and choose zip from sdcard, E: Can't mount /sdcard?

Quick question leapinlar. Does the 8 failed boots hard reset also restore the /boot partition to stock given your recovery is stock and not cwm or other?

Forgive me but does 8 failed boots mean turning on my nook and the initial phase of boot-up with"nook" just fades in and out and does hard reset mean pressing on power and n buttons simultaneously till it comes on? Thanks

It means
1. turn on the nook,
2. when it starts to boot up press and hold power until it turns off.
3. turn it back on,
4. repeat steps 2 & 3 8x.
It needs to be 8 "failed" boots, that get interrupted before it has a chance to get all the way through the process.

I did this twice and it booted up alright but right into this screen "EMMC CWM based recovery v6.0.3.2". I'm at myself, but I thank you all for your best efforts at helping me .

8 failed boots will not work unless you have stock recovery still on emmc. It looks like you replaced stock recovery with CWM. You either have to flash a stock ROM (which also replaces the CWM with stock recovery) or you need to flash my stock recovery zip from my HD/HD+ CWM thread linked in my signature.

Thanks, I will be following your instruction (perhaps flash your stock ROM) with a new microsd card. :fingers-crossed: Hope i'll get it right this time.

I did try using a new sd card and an old one, both failed; why is the message always "E: Can't mount /sdcard/"? I was hoping to sideload but my laptop cannot even recognize the nook attached by usb.

I don't know why it gives you that error message. I recommend you go to my HD/HD+ CWM thread linked in my signature and make one of my CWM bootable SDs from item 1. Then flash my plain stock 2.1.0 zip from my item 6.

I'll do that, thanks.
Hi all,
My Nook seems to have broken over night, more than likely the trim command was fired and broken my partition table.
I would return the item, but the Cyanogen Boot logo still appears. Is there anyway to remove it based on the nooks current bricked status?

If it shows that logo, it is not likely bricked by the trim command. Try making a bootable CWM per my HD/HD+ CWM thread and try flashing a plain stock zip from item 6.

Thanks for the reply,
Ive now tried different SD cards and both ways of creating a bootable sd card. but nothing works. I cant get past the cyanogen boot screen.
The TWRP image did boot but didnt get passed the splashscreen.
Any advice?

I have this EXACT same problem, I would love to find a way to get the cyanoboot splash screen to go away so I can get it exchanged for a new one.
Both of you only have two choices.
If you left stock recovery on internal before it screwed up, you can do the 8 failed boot procedure and it will reset itself to stock.
If you replaced stock recovery with CWM or TWRP, you must boot to it or a bootable CWM SD so you can flash the plain stock zip I have in item 6 in my HD/HD+ CWM thread linked in my signature. To get to your custom recovery on internal, power up from the powered off condition and hold both the power and n button simultaneously for 5-8 seconds. Then first release power and then a couple of seconds later the n key. It should show the cyanoboot logo followed by the recovery.
If you cannot do any of those things, you are screwed.

Looks like im screwed. It is strange though how the TWRP bootable image actually attempts to boot?
UPDATE: http://forum.xda-developers.com/showpost.php?p=44797803&postcount=73
I tried this and have managed to boot into cwm.
I then noticed a error that kept repeating. E:unknown volume for path [/cache/recovery/command]
So I then did the following
1. wipe data/factory reset
2. wipe cache partition
3. mounts and storage > format /boot
4. mounts and storage > format /system
5. mounts and storage > format /data
6. mounts and storage > format /emmc
7. mounts and storage > format /data and /data/media (/sdcard)
Alot of this did cause mounting problems. but I did notice I could mount /boot and browse sdcard from the "install zip" option. The only problem is the partion in the SD i can see isnt the partition that CWM can see.
I'm going to try and sideload the stock recovery using adb when I get in from work as I dont have the usb cable on me.
If you made a backup of stock prior to loading another ROM, you may have better luck restoring it than flashing the stock zip. That has been my experience. In addition to doing the restore, you may need to flash the stock recovery zip.

Well I couldnt get ADB to work with my tablet. So I couldnt sideload the stock emmc. So I then used "Paragon ExtFS for Windows" to copy the files to the other correct ext3 partition on the MicroSD.. I then booted into recovery and attempted to flash the zip. It didnt work, I recieved a error stating
E: unknown volume for path [/cache/recovery/last_log]
E: cant mount /cache/recovery/last_log
Looks like the nooks dead.
My EMMC became corrupt I think after it tried to do an internal recovery.
Now the only thing that boots is a CWM recovery SD card. However I can not install any zips as it does not mount ext SD, nor internal SD cards. It does not mount Data, or System.
Not sure how to solve as it will also not boot a full SD Card image.
What are the next steps to solve? I assume getting the EMMC partitioned and recovery and boot put back on the device?
Saw a similar thread about the HD, but it only had a hard coded link for a hummingbird downloadable:
flashable_fix_bootdata-hummingbird.zip
Does someone have a link to the ovation equivalent?
Thanks,
Rick
i was having a problem installing cm13 as it kept rebooting to the recovery screen.
i wiped all the cache's and reinstalled everything multiple times.
Then i found out that the emmc was not the image that i needed and grabbed the newest nightly image.
i copied it to my sdcard as a zip and installed it as a zip along with my other zips from the recovery screen.
it now runs fine.
i hope this helps you.
Please give details
