Unable to to Boot after CM7 install - Nook Color Q&A, Help & Troubleshooting

A friend of mine tried to install CM7 on his NookColor. Something went wrong and so he brought it to me. I've done dozens of these. I thought it would be an easy fix so I stuck in my trusty SD boot card with encore_CM72-MiRaGe-03042012. I booted into CWM and did a factory reset and installed encore_CM72-MiRaGe-03042012. I booted it up and expected it to be fixed.
It did the same thing this time which is to boot to the initial splashcreen and then go blank. You can tell the screen is still backlit, but it never changes. You have to hold the power button for 30 seconds to turn it off.
When I boot back into CMW I see some unexpected messages
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 tried installing CM7 again and watched the messages closely. It says
Installeding update
Install from sdcard complete.
Reboots the same way
Can anyone point me in the right direction to fix this? Thanks

Well, I spent all day yesterday Googling and searching all the forums on XDA Of course I started with Dummies Guide to Fixing 'My Nook Won't Boot'. It is incredibly out of date and is likely to do more harm than good. I think that if it is going to be a sticky, then at least it should show current, relevant information.
I tried [HOW-TO] : Restore Nook Color back to stock EASILY!. I was unable to format several of the partitions specified, but proceeded anyway. It appeared to install OK, but now I am stuck at the N when it boots.
I am continuing to search but I keep running into dead links, downloads that say they will take 5 hours, and references to outdated files. I really would appreciate some knowledgeable help here guys. Thanks

I have the same deal. I think since the WIP clockwork update. I've tried most of the fixes from the links as I still have most. I tried everything you have as well as trying restoring and using different versions of clockwork and trying to get a cache up to no avail. The please keep me posted because this is the first replica of my situation. I am using an Asus t101 now so I'm in no hurry but I've had me NC forever and love the reading size.
Good luck.
How do you create or fix the cache for e:? I can you ADB into clockwork?

Just in case anyone ever reads this thread I thought I would give some more information regarding my problem.
I am able to get into CWM 3.2.0.1 internally. I stiil can't get any ROM loaded though. ( I have loaded several different ROMS to the NC previously including the CM7 nightlies from 75 to 130, so I am well versed in how to do it).
I'm thinking there is something wrong with my partitons. I'm not well versed in exactly what happens during the boot process and what is on each partiton.
I though it might be useful for those people who know about this stuff if I supplied more info (since my eyesight is giving out from reading so many threads)
If I go into the mounts and storage menu and do severals format, this is what I get.
Format system - Error formatting /system!
Format data- Error formatting /data!
Format cache- Error formatting /cache!
I was afraid to format emmc or boot.
Does this help anyone?

Have you tried creating a bootable CWM SD card? That always helps me out when things get screwy.
Tried the EMMC recovery repair?
p.s. - NEVER format Boot. You'll have many a difficulty if you do.

I do have a CWM SD card and can boot to that as well.
Neither one works. I tried installing
nookcolor_1_4_1_update.zip
update-nc-stock-1.3.zip
encore_CM72-MiRaGe-03232012.zip
All leave me where I am now

How old is the nook?
What happened when your friend tried to install cm7? What was going on with it prior to installation?

Don't really have much info.
I have no idea how old the NC is.
I believe that the guy had stock B&N running and tried to install CM7 (verson unknown) with a bootable microSD card, I don't know if he was using the latest CWM on the card.

Um........mail it to me. I'll fix it.
Minimum fees apply.

Here's another clue.
I have a dual boot SD card made based on the instructions in
[ROMS]NEW! Dualboot Mirage CM7 / ICS CM9 Image for SDcard [3/26].
If I use it on a stock B&N NC, the SD card works correctly.
If I use it in the borked NC, it still boots into a black screen.
I would prefer to try to resolve this mayself. I have 20+ years in PC support and feel if I can just get the right information, I can fix it.
If I can't get it done in the next 3 or 4 days, I may take you up on it. However, the frind would have to OK it and I don't know how he feels about sending it off. Thanks
BTW, I tried plugging in the USB cable to see if maybe I could try some ADB magic, but the laptop slings an error when trying to load the driver.

Let me amend that last post. I tried the dual boot (this time using the alternate boot image) and successfully got into CM9. Does this help me?

I am trying to find a way to fdisk or mount a way to change pemissions to rw,mode=0755 or but cannot find the usb yet. I will see what I can google.
Seems the emmc permissions are wrong possibly.
Edit: this is what my mount says about the nook when I mount it to linux:
/dev/sdb on /media/0838-AA8D type vfat (rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks)

Since I have thee NC booting to CM9 off the SD card, I thought I would load ADB and see if there was something I could do..
I went to [Ref] Nook Color Links |Guides|How To|Utilities| Etc. 12/26 Read FIRST =) in the developer's section and went to the referenced
•Nook Color USB Drivers and ADB Setup (WinXP&7)
The links in that thread are dead. Can someone point out a link to the current prefered method?

have you tried

Hi there,
If you are able to boot to CM9 off the sDcard. Try opening up terminal emulator and enter the following commands:
Code:
$ su
# fdisk -l /dev/block/mmcblk0
and paste the output here. That should give you you're EMMC partition layout.
-Racks

Yeah, what racks said. Sounds like you formatted your emmc boot partition to me. In one of the old resurrected threads that you posted to, the OP flat out says they formatted boot.
Don't format boot, everyone.
Post the output of racks command, and we'll know for sure.
If you just formatted (read: erased) the boot partition, then your ROM partition should be intact. That means 8 failed reboot can load the stock firmware. It may be a last-ditch effort for many, but it doesn't require any adb knowledge our even a computer, so I tend to recommend it early.
Reboot as it is loading the cyanogen screen eight times while holding down power,n, and the volume keys. If it doesn't work the first time, do the entire sequence again. Of course, if you enter rack's command, you will see if your ROM partition is still intact which is required for this method to work.

Yep, your missing the last 4 partitions which are /system, /data, /cache, /media. Which you would need to flash any rom. You're gonna have to re-create them by using fdisk from and SDcard ROM (eg. CM7 or CM9). There's a thread here somewhere that dealt with all that. I'll browse through and see if I can find it for you.

This it?

[Q] Cannot Format /Data

Whenever I try to format /data through CWM 3.0.2.8, it returns the message.
error while formatting /data
Click to expand...

Also when I try to restore a backup, CWM cannot format /data.
I've also tried to install CM7. It says it completed its install in CWM but when I reboot, it retains the OS (rooted stock 1.2) I was currently on.
Me too. I just updated to MR1 and I am trying to restore the /data directory and I can't.
There's one thing I noticed about this refurb'd nook color. The space available in the device info is 1GB. Shouldn't it be higher or did they change the file structure with the latest models?
Also, I went into ADB and mounted EMMC. The last modified date for the files in there is May 4th.
Edit
Not sure if this would help.

Someone responded back to me on this forum.
http://androidforums.com/b-n-nookcolor/333668-format-internal-partition.html#post2672750
Barnes & Noble has started shipping new NOOK Color devices that are partitioned to allow only 1 GB of "user sideloaded" storage. The remaining 7 GB are partitioned for the OS, apps from the new B&N Apps store, and items downloaded directly from B&N. For the typical (non-rooted) device, the user would have to use the microSD slot for additional storage. I suspect you got one of the newly partitioned devices, which is why you are now seeing only 1 GB instead of the previous 5 GB of storage available.

Is there anyway to repartition the new devices or I'm stuck with this? If not, it's going to prevent me from dualbooting. This might also be the cause of my second problem, installing CM7 and still ending up with the original OS.
Oh man am I glad I found this thread. I was freakin' out when I couldn't load phiremod onto my newly purchased NC. Turns out I can only see 1GB of storage like the others in this thread. Hopefully some one will find a way to repartition the newer devices otherwise I am stuck with a rooted NC running the stock ROM with no way to return it.
You can just "Reset to factory default" and it'll remove the root. Then you can try to return it or exchange it. I'd probably say this if they ask for a reason...
"It's showing 1GB space as opposed to 8GB space as advertised"
Though I'm wondering why install CM7 doesn't change anything. After installation, it still boots up the stock OS.

Trying to load new ROMS fails because I can't do a data wipe as instructed.
I wonder if they made it so that outside sources can't write or modify /data now but it's still rootable with manualnooter.. I can format the other partitions through CWM and restore them easily.
EDIT
http://www.barnesandnoble.com/nookcolor/features/index.asp?cds2Pid=35583
*1GB = 1 billion bytes; Actual formatted capacity may be less. Approximately 5GB available to store content, of which up to 4GB may be reserved for content purchased from the Barnes & Noble NOOK Store.
I am not sure what kind of security they could have on the actual partitions, but the dual boot ROMS show that resizing the partitions should not be to hard, though it does mean you may lose data (possibly).
I don't mind losing my /data. I rather be able to install CM7 or something on the EMMC as opposed to running it on the SD.
I'd be grateful if someone could show me how to partition it so it's back to the original partition, 4gb/4gb as opposed to 7gb/1gb I think.
I hope something is figured out soon.
Here's the solution to anyone following this thread.

I had this problem too.. bought a brand new nook color... this is what i did using CWM 3.0.2.8 to boot off SD...
1. used manual nooter 4.5.6
(after applying had all types of popup force close messages about /media this /media that)
2. changed my patitions to match this post
http://forum.xda-developers.com/showpost.php?p=13003431&postcount=166
(Note: Although it said that it didnt write the partitions it actually did)
3. did the 8 boot reset and nook button reset...
(This didn't reset the partitions actually and I had 5.sumthin GB free space not 1GB as before)
4. Manual nooted again then installed Phiremod 6.2 and Dalingrin's Kernel 042411 for cm7....

I did this too and it scared the crap out of me when it kicked me out of fdisk. I thought I hosed it for good. Then when I did the 8 resets it kept going into CWM on the 8th reset. It wasn't until I rebooted it from CWM did it go and reflash itself.
Man that was scary. I thought I had a $250 paper weight.
I was a little freaked out when the fdisk said it didn't work... But reading around I seen that its almost impossible to break it as long as you don't mess with the first 3 partitions so what was the worse case I figured... This must be an issue with the CWR though.. Probably just updating the CWR to format different sizes of the partitions... A format with offset and length feature in an advanced menu... then we can change the sizes to what we want.. But going forward until CWR gets updated every new nook probably gonna have to do the partition change... Not like that's a big deal...
I bought a Nook Color used off craigslist cus they "bricked" it. I thought, no prob, through in the CWM uSD card, erase the data and system, and throw 1.2 on to root.
Can't erase the Data!
They said it was only a few weeks old. I'm guessing it was a refurb with new partition, they tried to root it somehow, and messed it up, then gave up.
Let's hope this fixes it!
Let us know if the partition thing works.. that would be cool.. GL.....

[Q] How do I partition the eMMC to support Custom ROMs?

I bought my NC last week and immediately rooted it with out a hitch using ManualNooter for stock 1.2. In the process of trying to flash Phiremod my NC locked up in CWM when doing a wipe data/factory reset as instructed. I did a hard reset and tried to load Phiremod any way, which failed. I ended up using the backup I made of the rooted clean stock OS and it is working.
I read this thread
http://forum.xda-developers.com/showthread.php?t=1077973
and mine has the same issue of a partitioned eMMC that only reports 1GB. This prevents me from loading custom ROMs and side loading any applications.
One of the posts on that last thread mentions how dual booting essentially repartitions your eMMC to allow for the said dual booting, so I tried the "Step 1" in the repartition process here...
http://forum.xda-developers.com/showthread.php?t=959461
And it failed, but did boot back into my stock rooted OS.
My question is...
Is there a way to repartition my NC with what seems to be a new partition scheme that B&N moved to so that I can load custom ROMs, sideload programs, and/or dual boot off of eMMC?
Would like to see this answered as well.
grab your oars....
I'm in the same boat.... I have the 1 gig partition on my new Nook.
I can boot from SD ok but I would rather blow out the stock and save my SD.
Help?

Anyone out there can help us repartition the newer nooks?
side load partition 1 gb on newer NC's
guys check this out. I am doing it now and will report back after I get this done.

boot repartition with stock 1.0.0 or 1.0.1, then side load 1.2 update from b&n site:
http://www.barnesandnoble.com/u/nookcolor-support-software-update/379002520/
If I read all this correctly.. this should do the trick. as well as re-enabling apk installs correctly with rooted stock?
Already tried that.
You'll get a 1.0.0 or 1.0.1 with 0 Space available and you cannot sideload because of that. All that does is re-write the folders and not partition it.
I even tried changing the factory.zip with an older version in the /emmc and did a system/data wipe through the 8 boot fails and power + n reset.
One possibility

If you are familiar with fdisk and mkfs.ext2 or are willing to learn, and can boot a rooted OS from the SDcard, it should be trivial to delete, resize, repartition, and reformat /data (0p6 -- ext3), /cache (0p7 -- ext3) and /media (0p8 -- vfat). Do note the size of the partitions (especially 0p7/cache) before deleting them.
Then, when you restart the NC, it should recreate the contents of /data and /media to virgin content (meaning you better have backed up any non-B&N content). You will have to reregister with B&N, so you should probably do this on an UNROOTED Nook.
This is an experiment that I have wanted to try, but have not had the time; I've been too busy doing other experiments, like having B&N do the intentional repartitioning. I was using internal dual boot before, but uninstalled it before the repartitioning, because I knew there would not be enough space for dual boot afterwards.
I'm just unfamiliar with the block sizes and the commands to partition/change it.

[Q] "Install failed" - partition broken?

Hi all,
I've got NST (with 1.1.0 software initially). After trying to root it properly I decided to restore original image and try again, because some added reader apps didn't start.
I tried to format NST as disk (deleting partition) and to write the ISO image I had (with my first backup).
After all, NST started as usual with "Read forever" screen and than after 10-15 second got "Install failed" screen.
Tried several recovery tools, they work from MicroSD, but after starting without memory card NST runs into the same screen.
Also tried "Touch-Formatter v2" CWM from this post
http://forum.xda-developers.com/showthread.php?t=1475613
Everything goes as expected, excepts strings appear such as:
"Can't mount /cache/recovery/last_log"
"Can't mount /emmc/"
etc.
But after reboot I have the same screen - "Install failed".
Also NST is not recognized in Windows as a mounted drive, just "unknown drive" appears for a second and then green light on NST turns yellow, and it goes for reboot.
If I use "mount USB storage" in CWM, connected NST is recognised as "bad disk" by Partition Manager.
Could anybody help?

Uh-oh.
You just made a backup of your boot partition, 1 of 8 partitions.
A full backup is on the order of 1.9 Gigs.
I hope that your formatting didn't destroy all your data.
You need to get ADB working with CWR and see what the damage is.
Try not to dig a bigger hole for yourself.
Take a look around these forums, there is tons of stuff about people who did the same as you.

Fortunately, I succeded writing backup image (shared by somebody on these forums) on NST with Noogie. It was almost 2 GB in size.
Thanks a lot for support!
Mmm, if you just duplicate somebody else's credentials you'll have a hard time registering for things.
You need the stuff out of your own /rom partition.

I don't think I'll buy books from the B&N shop, but...
I found only one file that may be related to ROM - "romrestore.zip" in the very first image of my device.

I´ve made the same mistake... your backup is useless... the correct file are bigger.
To correct this you will need to recover the ROM partition (have unique informations about your device) and replace this partition in a nook backup.
You can try this tutorial: http://forum.xda-developers.com/showthread.php?t=2104145
But the backup image available is for NSTG.

romrestore.zip sounds good but it actually contains no personalized data.
You need stuff like in /rom/devconf:
DeviceID
SerialNumber
MACAddress
PublicKey
HashOfPrivateKey
There is /factory/rombackup.zip which does have what you want.
You can mount the /factory partition with CWR.

The problem is that I have erased my own partition with everything excepts that small 76Mb part... It seems that "factory" sector has gone too.
But I think it's generally not a problem, if I don't need any service that checks some unique ID.
i have theoretical method
boot with noogie image , and use recovery programs to recover format files ,but the main problem is (u had overwrite the exist partition) and i think u cant recover it anymore
last thing ..... try to write ur backup (the corrupt 78 MB) to an sd card and hope that will share the Rom partition
PS : i was have same problem& mistake .... but i was lucky that my backup was with rom partition i from my corrupt backup
good luck

[Q] In need of a BOOT.IMG dump

Long story short, I screwed up my internal memory partition table and believe I've got it back.
Problem: I need a dump of /dev/block/blkmmc0p1 (and p5) if at ALL possible from anyone that has a working Nook.Color.
My problem is similar to this one: http://forum.xda-developers.com/showthread.php?t=918772
If only the files on this page were still active on Mediafire: http://forum.xda-developers.com/showthread.php?t=919353
That's the long and short of it. If you guys want some additional info I can provide any information, but as I said, a dump of someones boot partition would definitely help.
Thanks all!
-Josh
Your PM to me says you flashed my 3 zips. I generally don't respond directly to PMs, I prefer the forums. I assume you meant my three zips in my partition repair thread. The repair 145678 zip has a dump of that partition built onto it. So if that flashed successfully, and it still will not let you boot, finding another dump file will not help. If you want one, extract the one from there.
You may need to describe more what you have done and how it is acting now.

OK, I'll just start from the beginning with what I've done:
I have a Nook Tablet (not talking about it, just saying... I'm in the right forum lol) and a friend got a Nook Color and wanted to know if I could soup it up the same way.
Well I had it working and like an idiot, I accidently used the Nook Tablet "swap storage" routine to make /sdcard1 <-> /sdcard0 instead of the one for the Nook Color. It took the flash fine and upon reboot it claimed that the SD Card needed to be prepared so I let it format the "card"
That's all she wrote so far. I rebooted it again and it wouldn't even come on. It was at 30% power when I told it to reboot, so I figured it was plagued by the sleep of death so I let it charge all night.
Woke up, still nothing.
I made a CWM bootable SD card and LO AND BEHOLD, it started up without a hitch!!! But it complained constantly of "/cache" not mounting to store its log files (that was earlier today and it has been a LONG day so I cant recount the exact error message). When I tried to install the ROM again, however it failed all around.
Your partition 2 repair file failed at first for me, that's how bad it was.
After many different attempts, I setup a bootable SD card with Nookie and get a little further.
With Nookie, I was able to FINALLY adb into the device and fdisk -l /dev/block/mmcblk0 which revealed an empty table and with wrong cylinder, head, and sector count, which I fixed by using the information found here: http://forum.xda-developers.com/showthread.php?t=942324
After that, I remade my CWM bootable SD card and got better results. /cache errors are gone and I was able to use all three of your zip files for repairing partitions (forgive me for not having the file names handy).
That has gotten me a little further, but now I keep getting errors about /boot not mounting.
Also, I haven't just been using CWM, but also TWRP (which thinks my serial number is all 0s), but when I manually mount /rom I can see in the devconf folder that my serial number has been restored (before I recreated partition table and ran your 3 zips, that wasn't even the case).
I'm sorry this is so scatter brained. I've been at it for a solid 10 hours all while laid up in bed with walking pneumonia, so..yeah...fun times..
It could also be that I didn't partition it properly because partition 1 (the only 1) seems to lose it's file system type every time, while the other 7 remain intact.
If it did not have the proper cylinder head count, how did you repartition it? That quoted thread just says what the proper layout should be, not how to repartition it.

Well, I'm not EXACTLY a total n00b. I looked up the busybox/fdisk syntax.
First I did fdisk -C 965 -H 255 -S 63 /dev/block/mmcblk0 (as it was reporting nothing right)
That command got me the proper size of the disk and I, with help of the "m" help command" recreated it to this (now that I have adb working in TWRP, I'm back to my preferred parted, so this is not an fdisk printout, but a parted printout):

Hope of backing up any partitions went bye bye when I had to recreate the partition table the first time.
Now, is that the partition with devconf files or the factory.zip partition?
I'm still a bit unclear on that.

P2 is the one with the devconf files. P3 has the factory.zip, but more importantly it has the rombackup.zip which was the backup of p2 when it was manufactured. That is what my p2 repair zip uses when it reconstructs p2. If you don't have that info, you will never be able to boot to stock again. But we can make dummy info so it can boot to CM. If you got a backup of the p2 before it died, you will be ok.
BTW, I just used your fdisk commands to fix my bad cylinder count. Thank you.

You need to make three files to put in the devconf folder.
DeviceID has your 16 digit serial number
SerialNumber has the same info
MACAddress has your 12 digit MACaddress with no spaces or colons.
Also BootCnt should automatically get made by the system. It will not hurt to have a dummy one there. 4 bytes with nothing in it. That is the one that triggers an 8failed boot reset if it ever gets up to 8 in that file.
Also in the main folder should be a file call BCB (which means Boot Control Block). That should get created automatically by TWRP or CWM.
You get all that in there and flash a CM ROM and it should boot.
P3 does not matter unless there is a problem and stock recovery needs it. As long as you make sure that the DeviceID file is intact, you will never need p3.

No, it is because the original device name was zoom2. You do not want to flash that anyway, since you do not have a working p3. It does the same as my repair p2 zip.

Nope, once you verify those files are really there, just flash a CM ROM.

Two things, look at my edit above. And did you format those partitions after creating them? You need to. flashing my repair zip and format zips will take care of 145678. You still need to manually format p2 as fat32.
Edit: It looks to me like TWRP is doing some more checking that CWM does not do. You might try using CWM while trying to fix this. Also the new TWRPs do not like my zips.

I verified that the files were still present after a reboot and they were (plus a Lost+Found directory indicates that there's an active, formatted partition), but I am going to go ahead and format both boot and rom with FAT32 file system:
ADB Shell Commands:
mkfs.vfat /dev/block/mmcblk0p1
mkfs.vfat /dev/block/mmcblk0p2
Then attempted restoring again. Same process as before, except NO errors AT ALL this time, so seeing it as a ray of hope, I followed it up with the GApps package (in hopes that THIS IS IT....)
Good news, PROGRESS has been made:
Now, WITHOUT an SD card, the unit will power on and give me the Cyanoboot Bootloader, but just hangs at loading from EMMC 01
What do you suggest now? ( and when this is all said and done with I'm gonna be needing your PayPal account so I can thank you)
Those other partitions need formatting too. Use my 5678 format zip.

E:Unable to mount '/data'

Working on my Mom's Nook Color. Rooted at one time, restored to stock. I believe something got nuked in the 1.4.1 to 1.4.3 update and because of it's age, B&N won't do a thing about it. So it's up to me. I'd like to restore it to stock if possible but even repairing the EMMC enough for a ROM would be fine as my mom has resorted to a SD ROM. I personally would like to fix this because I've never seen an Android device I couldn't fix (yet). I've tried both CWM and TWRP with the repartition zips, installing ROMs and stock files, etc. Only thing I haven't tried to manual creating partitions through ADB. Issue I'm getting is that no matter if I'm wiping or installing, I'm getting an "E:Unable to mount '/data'" error. Oddly enough, when booted into CM7 on the SD card, I can see the 5gb of user data partition and can even place the Nook update file on it (from B&N) but Nook recovery never sees it when I boot into it manually. The 8 failed boots recovery method is the only thing I haven't been able to try and I can't imagine it would do anything more than the partitioning zips. Anyone here have an insight on how to manually partition this thing or how to fix this NC through any other method?
Did you use my format zip after you ran my repartitioning zip? That would give that error if you forgot.
Yes, you can repair the emmc partition manually with fdisk in terminal emulator (TE) in CM7 on SD. First thing to do is to enter in su mode in TE by typing su enter. Then run this command:
fdisk -l /dev/block/mmcblk0
It should list the configuration of the partitions. I suspect your cylinder/head/sector (CHS) settings are wrong. It should say 965 cylinders, 255 heads, 63 sectors. If it does not say that, you need to repair it. Type:
fdisk -C 965 -H 255 -S 63 /dev/block/mmcblk0
Then type the earlier command to make sure it is right.
Then you should be able to run my emmc repair zips and they should work.

You are right, it should be 255, I was going from memory. I will correct the above post. (Also can you either remove my quoted post from your above reply or edit it so users do not see my incorrect post?) Your partition table is ok. But from looking at the print out, you have not successfully run my partition zips. If you had run it successfully, p4 would end on 965, not 935. But I still think you need to run my format zip.

Nope, created a bootable SD using the TWRP in your thread. Gave me the same /data error after installing each of the zips. Tried installing 1.2 from the SD card, seemed to go fine but still gave me the /data error. I starting to think this is truly just a nuked Nook.

Ok first, please remove my incorrect post you quoted above.
Second, it sounds like the recovery is needing a valid /data partition before it will let you flash. You can repair it manually using fdisk. I will send you the commands via PM so noobs do not try this and muck things up.

Corrected the quote, will be looking for the PM. Thanks for all your help man! I'm good with repairs generally but not to this depth.

It needs more correction than that. I suggest you just delete it. PM very shortly.

Done.
Well I'm booting to the N logo and freezing. When I was trying to flash a rom over it before, it would not mount /data in SD recovery. Cannot get to EMMC recovery. When I flash from the dual boot SD with CWM, it doesn't give me the /data mount error but it still doesn't boot past the N logo. Beginning to wonder if my EMMC bootloader is damaged.

Back from the PM exchange.
Let me explain how the booting works. A lot of this is explained in my NC Tips thread linked in my signature in item A12. There is more detail there.
When the nook boots, it looks at p2 to make sure everything is ok there. If it is not ok not it tries to boot to stock recovery to repair itself. If stock recovery is not there or corrupt it hangs on the N logo. Obviously yours is messed up. So yes, your emmc bootloader files are messed up. Usually flashing a ROM to emmc fixes that. My emmc partition repair zip also fixes that. But you have had no success with that.
Also, usually when it tries to boot to stock recovery and the SD is inserted, it will boot only to SD recovery, not an SD ROM which yours does. So that confuses me.
I personally don't like or trust TWRP. You said earlier you tried to use one of my bootable CWM cards and it gave the same can't mount /data error. Yet you say the dual boot CWM did not. That dual boot CWM has been modified to put things on SD, so I recommend trying my bootable CWM again.

Well I tried with CWM 5.5.0.4 and it was addressing mmcblk1p2 for some reason so now I'm writing 3.0.2.8 to an SD. If that doesn't work, I'll switch to an older CWM. If THAT doesn't work, it seems a vat of acid is in store...

You need to explain these statements. How do you know it was addressing 1p2? You know that is normal for any CWM to do that? It is looking for a possible /sd-ext on SD. It has nothing to do with your issue. You know just enough to info to make bad assumptions. I'm just about to give up on you.

I'm done too. Just one more comment. I'm not sure why you are concerned so much about getting emmc working when SD works for you. If it is because you want stock for your Mom, you can try my stock on SD in my B section of my NC tips thread. It may not work if your p2 is messed, but it might be worth a try for her.
Done.
