I am at a loss. I got this working just fine and then started tweaking things and ended up jacking my NC and restoring it.
I wiped out and reformatted my SD card and did the verygreen method all over again. I want to run CM7 off my SD card. Everything went smooth and I saw no errors.
The first night I charged my NC over night and woke to found the battery drained and it wouldn't charge until I removed the SD card. After that I got the boot loop.
Came home and redid it all over. Once again it worked wonderfully until I restarted my NC and then it gets stuck in the boot loop again.
I have started fresh and have no idea why the issues. I have the latest stable and gapp. Am I doing something wrong in settings? Do I need to mess with ROM Manager at all if booting from the SD card?
Back up and running but still needing questions above answered.
Is there a thread that helps with CM7 or ROM settings after a successful install?
I just want to be sure I am not changing settings that are causing this. I downloaded Nook Tweaks this go around and not sure if that would give me issues. I didn't do this the previous times when I didn't have problems.

What kind of card are you using? Anything other than a SanDisk Class 2 or 4 can cause strange instability.
16GB Transcend Class 6. I guess I will search for a Sandisk Class 4 and see if that doesn't solve everything. One day it works perfect and the next it melt downs when I have made no changes. Maybe you are correct and it is simple as that.
I don't know how you doing but reading what you said ".... until I removed the SD card. After that I got the boot loop.", it doesn't make any sense, maybe you have done something wrong? because booting ROM off uSD shouldn't have any ill effect on the local internal OS.
You still have a boot loop w/o the uSD plugged?
What CM7 version are you using?
Also, are you using Rom Manager, or just Clockwork Mod Recovery directly to install CM7? Idk if things have changed, but when I was on an sd-card install, Rom Manager would always want to install things to emmc so it was easier to reboot into recovery and install updates manually.
I was also using an "off brand" sd card and would get force closes on apps. It might be possible, but I would suspect this is more of an installation issue than something with the card. That said, Sandisks are still supposed to offer the best reliability and performance.
You should only have a normal Nook Color OS come up every time you boot with the uSD out. It sounds like you may have flashed your emmc somewhere along the way.
I had a similar boot loop situation when i was trying to charge over USB with a dead battery (the nook kept restarting and running out of juice mid boot.) It corrupted my emmc CM7 somehow and it was fixed by reflashing once i had charged it from the wall plug.
Verygreen's method doesn't require rom manager.
Sorry for any confusion. I am not having any problem with the NC booting when I remove the card.
I just ordered a 16GB Class 4 Sandisk and I am going to give that a try. This current install is working fine but I haven't messed with any settings really.
Well, after a few weeks of reading posts, even opening up the hardware and taking the nook apart, here I am asking a question. I figure I would go to the source rather than those other place I was reading and tryign to get info from (mot os those places link here anyway). I know that everyone says that the nook is "unbrickable;" while I want to believe it, I may be in a place where it may be true.
I do want to add a thanks as well, since the NC "tablet" has been very handy, and my wife and I have really enjoyed it. Wouldn't have happened without you all. I wish I had more time to participate in developing, but working 80+ hours/week in a hospital limits my free time, as you can imagine.
I rooted the NC and installed Cyanogenmod 7 back in July 2011. It was a 1.1 model (if I recall correctly). I installed the mod to EMMC, along with CWM. Things ran fine for 6 months. Literally no issues. Then, one night the battery was dead, so I plugged it into the computer USB to charge while the machine was off. Didn't touch it at all. When I went to turn it on again, I was stuck in a bootloop. It would go to the cyanogenmod screen and say "Loading" then would start over again. So, I naturally made a bootable SD card, and tried going into CWR to fix things. However, the SD card had the bootloop as well. It would get to the two skulls and "Loading", flash blank, then start over again.
That went on for a while. I couldn't boot into anything, not into recovery, alternate images, literally nothing. So, I tried different images --- nothing. Finally, I did the power+n and got into the only screen that wouldn't keep resetting. It has blue text and says "Entering boot menu". The menu says "Encore U-boot Menu by j4mmr. 1.2 port+ extras by fattire." From this screen, I can navigate and change the boot options. However, once again, whatever I try does not actually boot, regardless of what I set it to. The only thing that I got from getting here was no more boot loops. After getting it to this point, I can try loading anything, and it will start, then the screen goes black/blank, and nothing happens. Left it on for hours to test.
Since that point, I have switched cards (SanDisk 2 GB class 4, Patriot 8 GB and a generic 8 GB microSD). I know that cards work correctly because I got a hold of a second nook, and they work fine on it. Below are a list of all the images I have tried to run off the SD. Again, nothing will boot, not even clockwork recovery/clockworkmod.
128 mb rootpack (IOMonster)
clockwork 3.0.2.8
clockwork 3.2.0.1 eyeballer
Nooter
Mirage_CM7_ICS_CM9_DualbootSD (this card works great on the working NC)
TWRP 2.0 RC0
Generic SD
Clockwork 0.7 -> starts boot loops again
I also tried ADB, connecting to the computer and using putty over SSH. Didn't work. 8 interrupted boots with 9th holding power+n. Nope. I even took the nook apart and disconnected the battery. Still no go.
If I recall, I think I had CWM 3.0.0.5 installed to the card and to the emmc.
If anyone has any other ideas, I could really use the help. I consider myself pretty computer literate (build my machines, coded in my spare time in the past, hacked a lot of my electronics). I have read many guides/sites and even tried the outdated stuff. Once again, I cannot get into clockwork recovery, so any guide that says to do that as the first step will not work. I also cannot boot off of the SD on cards that I know function.
Would using an older version of CWM (prior to 3.0.0.5) work? I think I remember reading a bunch of stuff about problems people were having with that version. The thing is, I wasn't installing or flashing anything new. I wish I was, because then I would know what was happening when everything got screwed up.
Thanks a bunch in advance for your guy's (gals?) time. This has been really painful.
Wow, that must be frustrating. First make sure you didn't change the boot settings to something other than the SD card when you were in the boot menu. As long as the Nook is powering on and doing something you can probably save it from being a brick.
I would start with a newer version of ClockWork Mod Recovery here: http://mrm3.net/blog/2011/03/11/nook-color-updated-clockwork-recovery-bootable-sd/
There is a contradiction in the file names but the actual version should be 3.2.0.8. If that doesn't work then you may want to go back to an older version. In that case I would still load a newer version's zip file onto that card, so that if you do get the older version to boot you can use it to flash the newer version.
Before going back to older CWM versions though give this a try if the new CWM above doesn't work http://forum.xda-developers.com/showthread.php?t=958748

Yeah, it has been frustrating, especially not knowing what happened in the first place. I actually did try the version from that first link (where I put 3.0.2.8). Again, the big issue I am having is that I cannot even get into the CWM. If I could, I could fix it. I also saw and read through that xda thread you kinked to (open right now in my browser), but the problem remains that I cannot even get to the point where I can flash something.
Thanks at least for responding. I'll try a few more things and see if it works, but I am running out of ideas.
In theory creating a bootable CWM card will get you into recovery even though you can't access the Recovery on the internal. Once you reach Recovery from the SD card you can flash whatever you need. It is just a matter of making a bootable recovery card that boots far enough to get you there.
In theory, yes, but as I said in my first post, I tried all the bootable cards without any luck. When I try to set the SD card as primary boot from that one screen from fattire, it locks and never restarts.

This happened to me a couple of times on CM7. Don't know why, but I believe I used the last method listed to repair it. There was an older version of CWM that would cause this sometimes. When you get it going again, you must update CMW to the new one.

How did you get it to boot into CWM in the first place in order to flash? That is my current problem. Any method of fixing relies on the ability to boot into CWM from the SD card, which (for whatever reason) isn't working at the moment.
Well, tried to use the native Nook u-boot. Get the "Touch the Future of Reading" screen, then black, just like with any of the other cards. On the good nook, it boots into a linux file and runs the recovery script, so it is not the card reader or the SD card.
Well, still doesn't work. I guess I officially bricked it without even knowing what happened. Bummer.

You said you tried eyeballers 3.2.0.1 CWM. Did you mean the 1GB image file he posted on his thread? And how did you burn the image to the card? You should be using win32diskimager running in administrator mode on Windows. And it is best to use a cheap card reader rather than any card reader built into your PC. The nook can be really finicky about how the card is written.

Yes, I tried that image from his thread. I always use win32diskimager and use a card reader. I have working cards (I have a second NC that runs fine); there is just something wrong with the boot process, and I cannot get into CWR to fix it. It starts, but then never makes it in or reboots. Only time I can keep it from rebooting is by holding "n" and going into the boot option menu.

It goes to the boot menu when you hold n with eyeballers image burned to SD? What happens when you select SD and normal? Just a hang? With 'loading' showing?
Edit: I just thought of another reason that could be causing this. There is a flag set in /rom that tells the system to try to boot into recovery. It tries no matter what you tell it to do in the boot menu. ROM Manager uses that flag to boot to recovery when you tell it to. Then after you successfully get into recovery and exit it by telling CWM to reboot, CWM clears that flag. If your recovery is borked up, you never get that flag cleared and it's an endless loop.
There are two solutions I can think of. First, use racks dual boot SD that you already have and go into the boot menu with that. Tell it to go to SD and recovery. Hopefully his recovery will load. Then immediately exit by the menu. That should clear the flag. If that fixes it and it boots to CM7, go to ROM Manager and flash a new CWM to emmc.
If that does not fix it search xda for 'fix recovery'. There is a nook thread telling how to fix the recovery on emmc.
Edit2: I just thought of a third way to try to get it to boot. Take eyeballers 3.2.0.1 CWM SD and put it in your PC. There should be two files there named uImage and uRamdisk. Make a copy of them on the SD and rename the copies to uRecImg and uRecRam. Then put back in nook and reboot to see what you get.
Hmm. Thanks. I'll definitely give it a shot (got nothing to lose at this point). I'll get back and let you know if it worked or not.

Hello? Feedback?

Ha, I tried the quick reply function, and it didn't work. Here is what I wrote yesterday (verbatim, since I still had the window open):
"Well, so far no luck. Here is what I have tried, and the new information that I learned.
Used dual boot SD that I know works and booted into bootloader menu. Tried all different options on the SD card. What happens is that it thinks for a bit, then turns the screen black, but the boot screen never comes up (i.e. the Cyanogenmod logo that usually starts before things boot). So there must be some problem there.
If I hold down power, it will restart. Again, the screen turns black after the loading screen is on for a while (happens no matter which image I burned to the card).
I still need to try the other method (eyeballer one). I don't think the EMMC reset will work with my particular issue, as I had read that thread earlier."

If the problem is the recovery flag, the mods to the eyeballer CWM SD should work. If it does not work, it may be something else. If it does work you can flash a new CWM to emmc using another eyeballer zip. Get it here:

Cool. Will give it a try tonight and report back. Just have to find my spare SD card.
So, tried with the eyeballer, and I couldn't get it to work. One thing I did notice, though (actually by chance) is that even though the screen is black, the nook is on. I saw this because it all of the sudden started flashing the low battery screen and then turned off.
Anyhow, still looks like I am in the same position. The EMMC fix doesn't work for me because I cannot even boot of an SD card.
EDIT: Actually, I just reread your post. I didn't do it right. I am going to try again and report back.
EIDT 2: Nope, didn't work. Do I need to hold all the buttons down while booting or do something else special?

I'm not sure what to tell you to do next. I guess I am going to send you to a post that tells pretty plainly how to do the 8 failed boots. I know you tried that, but timing is very critical with that procedure. Worth a try to me.
http://forum.xda-developers.com/showthread.php?p=25405429
How do you do the 8 failed boot deal with the cyanogenmod screen running. I am not sure about the timing of things. Also, which buttons? I have seen people do it with just the power button. Other places say with the power+n+vol up.
I see that there are other posts on this same subject and I have looked through them to try and fix my problem but I haven't found a proper solution yet. I rooted my NC (1.4.3) cm7 and it worked alright after that but apps weren't available for the version so I attempted an update then reboot. I powered down and pulled the micro sd then powered up and it gets to "Read Forever" then goes black. I have tried cm10 with manual nooter in order to try and re-do the partition on the device but it won't do anything once I put the card in and try to boot. I have had to dis-assemble it so that I can pull the battery and get it to power down completely. I have tried a factory reset boot, sd card boot with auto nooter, manual nooter, cm7, cm10, and other options on the sd card, I have also tried to boot directly from internal memory. I have tried the process of plugging it into the computer through the usb cable. I have charged the battery completely so that isn't a problem.
I have read that it is virtually impossible to brick this thing but I think I might have succeeded....any input on what I can try next would be helpful...

You need to do a better job of describing your situation if you want help: how your NC was set up; exactly what you did that created the problem; what you want to end up with. At a guess, I will assume the you were running rooted stock on EMMC and CM7 on SD, decided to update CM7 to CM10, but used directions for updating CM that was installed to EMMC. I am not an expert on this, but sort of remember Leapinlar posting advice for someone (or maybe a few (?dozen?) someones) with this problem, you might want to search for those threads.

Here are the exact steps that I took to get to where I am:
I rooted the stock EMMC with the manual nooter to be able to get the Google Play Market, that worked well and I had access but the Android version was so old that I couldn't install the apps that I was after.
I then attempted to flash the EMMC to CM7, all status came up as pass and I rebooted. when it came up after the reboot all I got was the "Read Forever" screen.
since then I have read many different posts and tried to boot from the SD...that doesn't work, the screen just stays black
I have tried to boot to CWM to repair or rebuild the EMMC...same outcome
once I remove the SD all I get to is the "Read Forever" screen...
I have read and tried all the steps listed in every post you listed but they all have the same outcome
I have attached a pic of what the screen looks like when it tries to boot.

Hopefully someone more knowlegeable will look in, this is above my level. The fact that the Read Forever still displays shows that CM did not install correctly, if it's a newer version. You might want to try posting your problem in the same thread that you got the install instructions from.
I have a Nook Color that I've used for some time with CyanogenMod 10.2 with no problems. Last night I was looking at the fixes for Netflix since CM currently has a problem with it, and followed the instructions on XDS for the xposed installer (loading Liquid64's NetflixHackPersist.zip). Things appeared to go fine, and it booted into CM again and I ran the app as instructed. Everything seemed fine up to that point.
But on rebooting, the Nook will not go past the Cyanboot screen. Whether I let it boot by itself, or go to the boot menu and select any of the emmc or SD card options, it just sits there saying it's 'loading xxx' whatever option I've selected and never gets past it. I cannot find a way to force it to boot to the SD card to try anything that way.
I've tried 2 SD cards, reformatted and reburned an 8gb clockwork 3.0.2.8 image to make them bootable...so I don't think it's a card problem.
I'd appreciate some help if anyone knows a way around this. I've had experience with rooting and loading from the SD card, but if it always gets to Cyanoboot and I can't get it to even boot the SD card, I'm stuck. (The 8-reboots trick doesn't seem to work..I've likely reworked too much to still do that.)
Thanks,

Hallelujah! I followed your link and (though what I saw suggested trying CWM 5.5.04 for CM 10.2) it WORKED!! It booted to the SD card from Cyanboot, and I had a CM 10.2.1 zip that I was able to install and I'm back in business.
Out of curiosity, is Cyanoboot something unremovable, meaning I can never simply boot straight to an SD card as in the past? It did let me get to the recovery on this SD card, so I guess Cyanoboot was actually working and my problem was something else...but if I simply did a factory reset and wiped everything, would that have removed Cyanoboot as well?
If anyone has suggestions, I'm trying to decide if I'll keep this thing or sell it, so I'm curious what the most fully functional ROM (CM or ?) is considered to be these days, if I didn't put it back to stock?
I've loved this Nook, and only got into the earlier predicament because I thought, if I sold it, a buyer might want to use Netflix...so I was hoping to have it working with a ROM that would please the average Joe user who might hit up Youtube, Netflix, etc.
Thanks for the help!
