So I've been using my NC for a while flashing roms no problem. I tried honeycomb emmc and it works but I want to go back to cm7. Didn't make a nandroid backup (wanted to start from scratch on purpose) . I can reflash honeycomb fine. I can also always boot to cwr from my recovery SD I made. What am I doing wrong to prevent cm7 from booting after flashed? I want to continue loading cm7 from emmc, not the SD card. Any ideas?
Should add I've tried cm7 nightly 114 and another 103 I believe, which was working perfectly before I flashed honeycomb. It displays the cm7 boot logo then just an all black but still powered on screen. Never makes it to the boot animation.
Kinda at a loss for ideas here. I'm sure it is something simple that I missed, but I'm not finding anything like this on XDA. Right now my nook is either booting to recovery and sitting there, or just a totally useless paperweight. I know it isn't bricked, I just don't know what else to try to get back to CM7.
shamless bump. I have spare time today to play with this.
Did you wipe /system and /data before you flashed CM7?
Absolutely.

Are there additional steps I'm missing? This is the first issue I've had flashing the nook or any android device.

I seem to recall CM7 not booting for me after one of my play sessions. Although I hadn't loaded Honeycomb. The only way I could get back was to flash Nook 1.2 from a CWR sdcard and start over.
I just flashed nook froyo 1.2 that keeps CWR and still am unable to boot. If it wasn't for booting to my CWR SD, I'd be scared I bricked it.
What are some known good ways to get back to 100% stock? I don't mind re-rooting. Is there a RUU file or something?
I also recall having to remove the emmc CWR that ROMmanager installed (without really asking or making clear what it was doing).
In the DEV section there's a zip that removes the CWR boot and returns to stock boot. I'd try that.
I'm surprised there are no experts on hand to offer more guidance - it's a bit like sleepy hollow here!
I did try that zip if we are thinking of the same thing. IDK what is going on. I can't get it to boot on 1.0.1 BN, 1.2 BN, CM7....I'm really worried now.
Sorry this is not an answer to your question, but I wondered why you didn't like honeycomb and want to go back to cm7?

Honeycomb isn't a complete port... it has no hardware acceleration and doesn't do a lot of things that CM7 can, probably due to the nonavailability of the source code.
Also, OP, try this: http://forum.xda-developers.com/showthread.php?t=914690&highlight=stock
If you can't get that to work, PM me on here and i'll try to help you out
i posted a while back in here, and the help i got didn't do much of anything. so now i'm desperate.
This isn't even my nook color, it's my dads and right now he's pissed because it's bricked more or less.
it boots, and gets stuck at the android screen. NOTHING was done to this other than installing CWM, CM7 and then it just sat there, no one used it for almost 3 months. Then when he tried to turn it on. stuck on android.
i tried holding down the power and N button, but it never boots into recovery.
So i had CM7 and CWM installed to the internal memory (because i couldn't get an sd to work properly)
now, i want to either wipe it and get it back to CM7 where i'll just reinstall everything, or totally wipe everything off it and get it back to stock.
aside from nexus devices, i'm a total n00b so please, i need easy to understand instructions here to get this thing working.

Go here Dummies Guide to 'My Nook Won't Boot' and read.
OK, so I wasn´t paying much attention and instead of formatting the system, I formatted the boot of my Nook. After that my Nook wouldn´t boot into EMMC CM7 nor EMMC CWM.
After creating a bootable sd-card I manage to get the EMMC CWM going but, no matter what ROM I tried, or what I wiped, I can´t boot on CM7.
I tried reading every guide and post that would suggest a solution to my Nook but every time i try to download something that is supposed to work I get a broken link. I even try to go back to stock but I cant find a working link for that either.
Anyway, I dont want to go back to stock. I want to get the CM7 going again.
Can anyone help me here?
I got it working again!!!
So, in a overtime hail mary moment, i got it working again. Thank you, xawen!!
Here is how I did it:
I downloaded the "RecoveryFix_3.0.2.8.zip" file from xawen´s post (http://forum.xda-developers.com/showthread.php?t=958748) and install it with the bootable sd-card CWM I had created.
After that, I removed the sd-card and reboot.
This time the Nook showed the "Touch the future of reading" screen (not the Cyanogen screen) and entered into EMMC CWM. I install the "update-cm-7.2.0-RC1-encore-signed.zip" file and reboot. I didn´t wipe anything this time (because I had wiped everything over and over again so I bother).
After the cyanogen screen everything went black and I waited. It took a while, but then, all of a sudden, that little blue fellow showed up. It had never made me happier!
I hope this can help someone else.
Hello,
I was running one of the CM9 nightlies and decided to try one of eyeballer's with OpenGL, and was able to make the switch without any problems, but after a while wanted to go to a non-openGL build and after flashing it my Nook won't boot past the loading screen.
I have a 1GB card with CMW which I'm able to boot to, I've tried wiping data, format boot and format system and reinstalling one of the builds that had previously worked, but still get stuck on Cyanoboot's loading screen. Even tried going back down to CM7 to see if that helped, but stuck on that loading screen as well.
What am I missing here? I've formatted boot, system, cache, data, everything, but the issue persists.
Any suggestions as to how I can make my Nook come back to live.

Well, for one thing, never format boot.
After trying cm7, you still get cyanoboot? It should have changed to the green cyanogenmod logo. If not then your flashes are not working.

After flashing CM7 I get the green boot screen, but my Nook also gets stuck on that loading screen.
When flashing CM9 I can press the ''N'' button and scroll the available boot methods, but when I choose one I get stuck on loading again.
So on both CMs I'm getting stucked on ''loading'', which started to happen on Monday after going from one of the openGL builds to the latest non-openGL build.

Ok, that means that CWM is putting the boot files on the boot partition since they change CM7 vs CM9.
Which version is your CWM on the SD?
You can't boot to anything, not even emmc recovery? Or you just can't boot to 'normal'? Do you even have emmc recovery installed? If you don't, get the first file on this post and flash it with your CWM card. You may be in a recovery bootloop, without a recovery.

Thank you leapinlar, seems like it was me having an old CWM on my boot card that wasn't helping me, installed the recovery zip and manage to boot into that from cyanoboot's loading screen and reflashed and managed to boot my Nook.
I'm still intrigue as to how this happened, do you think that when switching between openGL and non-openGL the boot partition got corrupted or something? I've been flashing many roms for almost a year and had never had this issue happen to me before.
Thanks a million for taking time to help me, you're a life saver.

It's possible your recovery somehow got corrupted during the flash. If that happens, it does not clear the recovery boot flag and it keeps trying to boot to recovery and it can't because it is corrupted. And it just bootloops forever.
Also, make sure your CWM bootable card is a recent version. If you have a newer nook and an old CWM and you try to clear data, it fails and you have a mess.
Hi, I am totally new at this but I been having a nook color for over a year now and been running CM7 on it for the longest time. Tonight I wanted to put CM9 on and for whatever I did now I just can't seem to get pass the Cyanoboot screen. Doesnt matter what I do it just gives me a blank screen and stays there. What do I gotta do to fix it or get rid of this cyanoboot and back to CWM so i can re flash everything. Any help would be great. Thanks

Try flashing latest CM7 then CM9 over the top. Might want to format Data and wipe caches in between.

Try using my bootable CWM card in my tips thread in my signature. It works fine under ordinary circumstances, but I have been wanting someone to try it to see if it gets you out of that bootloop.
Edit: Just a question out of curiosity. When you finished flashing that new ROM with your CWM, were you able to reboot from CWM normally using the menu choice? Or was there some lockup or something where you had to reboot from CWM by hard powering off?

I believe i had to powering off. I'm sorry but I didnt quite understand what you told me to do with the bootable CWM. I am fairly new to all this flashing ROMS crap. If u can explain it a lil bit better that would be greatly appreciated.

Just follow the directions in the thread to make the card. Then put it in the nook and try booting. If it boots to CWM, just use it to flash like DizzyDen said. And when you exit, use the menu to choose re-boot.
PS, the hard powering off caused the problem. CWM was not able to clear the recovery flag and you ended up in a recovery bootloop. Let me know if my card boots.

Thank YOU for testing my card and proving that gets you out of the recovery bootloop you were in.
You need to take one more step. You need to put a new CWM back on your internal memory so it is there ready for the next time you want to install a ROM. If you go back to my tips thread, there is a link to a new flashable CWM zip (version 5.5.0.4) that can be put on your internal memory. The link is in item B1. Just download that zip file, then boot one more time to my bootable CWM card and install that zip. You should not need my card anymore after that unless you get in a bootloop again.
I've had something similar going on. I believe my nook has been using the EMMC to boot. It was on CM7. I grabbed the latest open GL CM9 because I plan on giving this to my parents. I wanted them to be able to use the TWC TV/DVR app which only works on ICS. I am stuck in a loop where it keeps going to recovery and neither flashing cm9 again nor recovering to an old back up is working. Is the recovery SD card the suggested method for fixing this? I'm not stuck in a loop but I am stuck and having to go into recovery every boot.
For awhile, the N menu gave me both EMMC and SD card boot options. Now it only has EMMC ones.

You could try the new CWM SD. Just make sure when you finish using CWM to exit from that by using the 'reboot' choice in the menu. Do not just hard power off.

So slap the image on a clean SD card and boot up from it. After it's done and I hit reboot, what would I do to get back to CM7 or CM9? I haven't had to do something like this yet. Any time I've had issues, I've been lucky enough to go back to a saved clockwork backup and restore things back to how they should be

First thing I would try is just to exit the new CWM via the menu to see if it gets you out of the bootloop. Retry booting without the SD in. If it will still only boot to recovery, I would again boot to my CWM and flash the new recovery to emmc. Next I would try to restore your old nandroid backup with the new CWM. If none of that works, flash a new CM to emmc with the new CWM.
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!
