NC won't install CM7, format data, or boot anymore

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!

Stuck in the CW recovery screen, tried everything.

I searched everywhere, but can't find the same problem as mine. I am stuck in the CW recovery screen, after rebooting times after times.
I have been updating the CM9 nightly for a while, didn't have any problem. But when I tried to flash 02-17 nightly, I messed up and in the middle of the install (flash), I hold the power forcing to reboot. Now, it keeps going loop back to the CW recovery screen every time I tried to reboot.

I tried to reinstall the whole thing with the boot-able sdcard, but didn't work. please help! someone?
I tried to wipe, reformatted the system, data, cash, boot. Still stack at the cw recovery screen. Help...
I love my nook and have a road trip coming up. It will be nice to watch a kid movie to keep the kids entertained.

Had you flashed CmWR into eMMC?

Check the ROM information on /dev/block/mmcblk0p2.... this sounds a LOT like the problem 12paq had...

@Dizzyden, thanks for the tip.
I did repartition to 1g/5g awhile back. I am not sure where to start. 12paq tried many things, which one was the solution? Your rombackup.zip?
Many thanks....

@votinh
what do you mean? I am not using the N&O apps or OS. Pure CM9, therefore I guess it is flashed in eMMC. If not, please advice.

I tried to adb shell the nook, but not devices found? please help.
Finally, with the help from the good people of this forum, I was able to restore back to B&N, and reflash CM9 from there.
Thank to you all.

Yesterday my nook color was working great. Today I turned the screen on and it hung. Now I'm having the above problem with it hanging at clockwork recovery.
I've got CM7.1 stable on there running from emmc.

can't get adb to recognize the device since it is in cwr... how did you do it?

Install the google drivers for adb... if you are in CWR adb is enabled... just have to get the drivers loaded on your computer.

It may be that your "boot to recovery" flag is set, and if so, it will always boot to that until it is cleared. When the cyanogenmod logo comes up hold the n button until the boot menu comes up. Then choose boot to emmc. If it works, go to ROM Manager and flash a new CWM Recovery to emmc.

Welcome to the nightmare I lived last week. Don't worry I woke up, was able to fully recover and forget the dream ever occurred.
I to tried to reformat to 1gb/5gb and ended up in the same boot loop.. If you are in the same spot I was, your boot partition got wiped out. And you may notice EMMC is gone.
After much searching I came across a file... Looking....Looking...Looking...
..........................Ah yes here it is. Here is what worked for me.
1. Boot to recovery (Should be easy at this point)
2. Format System, Data, and Cache.
3. Install the attached Zip file. (RecoveryFix.zip), this should recreate the Boot partition and fix the EMMC.
4. Reboot to recovery
5. Install favorite Rom or restore from backup.
6. Reboot to test.
Again this is what finally worked for me, and I went through a lot of trial and error to get there. I am guessing at your situation being exactly the same as mine.
PS. Ignore my since of humor if you need to.

[Q] Nook stuck on loading on Cyanoboot screen

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.

CM7 boot loop (racks triple boot)

Nook color running Racks triple boot via micro SD card. Micro SD card is a Sandisk 8GB class 4 card.
Was previously running fine for many months with the 2/2/12 roms. I would run CM7 99% of the time and I would get a random reboot here and there, but otherwise very stable.
A couple days ago, I had a random crash and tried to reboot CM7. I could get passed the boot loader screen, but then would have a continuous boot loop with the blue android symbol.
Thinking something was corrupted with the rom, I booted to recovery and tried flashed the rom along with gapps. Still boot looping.
I booted to CM9, and was able to run. So I downloaded the latest CM7 and CM9 roms for Racks triple boot. Flashed both along with the gapps and CM9 fix. Apparently I got lucky and was able to boot into CM7.... once. Thinking everything was OK, I went on with my life and ran the new CM7 happily.
Now, a few days later, I've tried to reboot and I'm back at the same boot loop with the arrow spiraling around the a blue skateboarding android. Note, in that short time that I was running the newest Racks triple boot CM7 rom, I did not run a backup, so, I'm basically out of luck with recovery via CWM.
I've flashed the 2/2/12 rom as well as the latest rom to see if either would work again. nothing... still boot looping... for hours now.
Any suggestions other than wiping the SD clean and starting with a fresh install?
Thanks all.
~mike

Bump...
Been a bit, no responses yet. Anyone have any ideas?
Thanks,
~mike

I think the fresh install will help since you already tried partial reinstalling the roms.

It won't boot from an uSD card with clockwork on it and when I tried the 7 hard boot in a row trick, it didn't do anything. Did i really brick the thing? or can it be recovered?

You are in a recovery bootloop with no recovery installed. Go to my tips thread linked in my signature. Read item A8. You need to make and use my special bootable CWM SD (select the 'larger' image). Then if you want to return to stock, read item A15.

[Q] Stuck on Cyanoboot loading screen..

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!
