Where to begin...
So I based my install off of this YouTube Video: youtube.com/watch?v=88qRbLLEAPQ and after I got done following everything to the T, I was not able to format /data. I feel this may be my problem. After doing all the steps minus that one I tried to install CM7 and it would boot the second time around in CM7 (Something I read was common). IT would get the the skateboard screen and then it would just stay there with the arrow continuously looping around and around. I let if sit for quite some time before I had to power it off.
I called up my buddy who told me I would more then likely have to install it manually with the Android Developer tools (Or whatever he called it). I did not have those tools so I kept poking around online. I found that sometimes the SD card caused problems so I bought a new 4Gb class 4 card. This was not the issue.
I poked around alittle more in CWR and I accidentally formatted /boot. The unit froze up so I restarted it. It booted into CWR just fine and after trying to wipe the /system, /data (Still not working) and /cache and rebooting, it has now just turned to a black screen that I can't even boot from a card.
Now before I just cash in on my protection plan, What can I do to get this running again? I hate having a paper weight sitting on my desk..
Thank you so much!
tl;dr, Tried to install CM7, can't format /data, tried new card and re installing, accidentally formatted /boot and now it won't boot at all.
Honestly, I can't watch Youtube at work so I am clueless what instructions you are following.
1. What version of your NC? 1.2? 1.1? 1.0?
2. What version of CwMR?
3. You tried to install CM7 in the eMMC or uSD?
I don't know which Nc it is... I just got it 2 weeks ago today.
I do believe that the cwr was 3.0.0.3 or something like that... it was supposedly the newest.
and it was the latest stable version of CM7.
My problem now is that my computer has totally crashed and it won't start in safe mode even. I am fairly sure it has something to do with having the files on my computer.. I just have to get that part figured out, then I can get the rest of it working..
Latest CW is 3.2.0.1 if I recall.
I know when I leave my imaged microsd card in my adapter on the laptop that the laptop won't boot. You don't have the card in an adapter on the system do you?
Also, I assume you are trying to install CM7 to internal memory?
You have to use CWR v. 3.2.0.1. Earlier versions will not wipe/clear everything. Do that and you should be ok....
If it has been around 2 weeks ago, then it most likely be v1.2 which you need CwMR v3.2.0.1, which reportedly fixes the format /data issue.
Give it a try again.
Ok, got the Nook to boot back to the Nook software. Won't get past the loading screen, but atleast it is booting..
I got my computer working finally after booting in Safe mode and deleting all the zip files and images from the computer. So now I am back to a clean slate.
Where do I get CWR 3.2.0.1? And then where do I get the CM7 latest release? I feel like I should be listening to you guys rather then listening to the YouTube video.. It was nice to see things happen on there, But it did not work for me.
Thank you guys SOOO much for having this forum and the "How to fix the black screen" tutorial! I would be lost without it!
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:

You would want the first choice.

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.
Hi all,
I bought my kids nooks for Christmas and rooted them all with cm7. Recently my oldest son decide he wanted to clear his nook and set it back to the factory state... (no idea why) regardless he decided to do it on his own which I only found out about after he had er bricked it. Here's a description of what he says he did.
1-Wiped the SD card
2-Copied the nook software to the sd card
3-rebooted into recovery mod
4-deleted anything he could delete? No idea, this is where I had to laugh
5-rebooted the nook, it didn't... Go figure
I'm not sure what version of recovery he had but it had to be an older version. I tried the various resets but I'm pretty sure the internals been wiped... now I did connect it to a PC and just cycled the power and it will chime recognition for a sec but then its still dead. Is there a way to create a new internal boot loader or is it spare parts?
Thanks either way, love the site

You may want to try to boot ClockWorkMod off an sd card(here is a link to a forum post about it) and if that works then you will want to follow leapinlar's post to repair the partitions here
Your issue is he probably formatted /boot (older versions of CWM allow that). If he did that it will not turn on unless there is a bootable SD in the slot. The solution is to go to my partition repair thread as the last user recommended and follow the instructions there.
Sent from my Nook HD+ running CM10.1 on emmc.
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,
JT

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!
