Nook Won't Boot After Formatting SD Card

My Boot will not boot no matter what I do. I encountered this issue after flashing to phiremod v4, which worked beautifully until I decided to free up some storage space on my SD card and format it through the Nook. The next time I tried to boot, I got the dreaded black screen.
I've burned Clockwork Recovery (4gb v .7) onto the SD card and copied the Nook Color V1.1.0_r2 rom (found here http://forum.xda-developers.com/showthread.php?t=932145). From there, I formatted the data, system, and cache, then installed the rom from the SD card. Everything went through smoothly, until I rebooted the Nook (with the SD card out). Nothing happens! The Nook simply will not reboot without the SD card inserted. Even if it boots (with the SD card) it just sends me back to Clockwork Recovery.
I also tried recovering the Nook through ADB (using the steps found here http://mrm3.net/2011/01/24/113/). I install everything, but I cannot locate the ADB device in the device manager. I've even used the .bat file to auto installs ADB, but it is still not found in the device manager.
I've read that it is nearly impossible to brick a Nook, but I'm not sure what else to try. I'm a Android noob, so please bear with me. TIA!

Fairly certain I read about a bug with formatting the SD card on the NC, that it would format the internal memory instead. I would imagine you will need to flash a new image to the internal memory (should be stock image floating around here somewhere).

No worries, you are most likely NOT bricked. There are hundreds of posts about people thinking they bricked their device.
First thing is first, IF YOU READ THE POST IT SPECIFICALLY STATES DO NOT FORMAT THE SDCARD USING THE NOOK AS IT WIPES THE /BOOT
My suggestion to you is do some research on XDA there are PLENTY of posts about "unbricking" your device.
I have only seen 1 nook be bricked, and it was hardly bricked because it could be booted from an SDCard.
Try following the instructions here to return back to the stock OS:

Yeah, I realize that was a big no no. I am unable to perform any of the steps in the link you provided because my nook doesn't even reach the 'Welcome to the future of reading' screen. Also, I can't try method 2 because ADP is not working properly.
I should mention that I also tried samuelhalff's first method to no avail. Any other ideas?

So you CAN boot from an SDCard correct? Only way to boot again is to flash the boot file...

Yes, I can boot (to Clockwork Recovery) if the SD card is inserted and the power cord is inserted and I hold the power button for 10 seconds. If I install a rom from the SD card, doesn't it flash the boot file? If not, how do I flash the boot file?

I know you said you tried Sams method, I would re-read how to flash his boot repartition file found on his froyo on emmc thread

Here's the link to the boot file. I did the same thing not long ago (formatted SD from within CM7) and I fixed it by flashing this file to repartition the boot.
It's the last link in the OP of this thread (repartition-boot-with-stock.zip):

If that doesn't work, he has a couple of restore to stock methods in that thread as well.

YES! This did it! I missed this link somehow. Many thanks to all that helped.

Ok, now I'm stuck on the screen that says "Contains Reader Mobile technology by Adobe Systems Incorporated". Did this happen to you C Dippa? I'm going to try a reset and see if that helps.

Nope...it just booted up, may have taken a little longer.
Any luck with it?

Yeah, I had to do the 8 failed boot attempts to bypass that screen, then re-root. Now, I'm all set! Phiremod is installed again.

Glad to have helped! Happy nooting!

New to Nook Color

So I finally took the plunge and picked up the Nook color, bought it second hand with HC already on the eMMC so I am not sure exactly how anything was done before. I have been reading the guides and while not completely lost, there's just some things I am unclear of right now.
I installed Rom Manager to install CWR, after installing and flashing it I cant access Recovery, but wasnt sure if it ever worked. Was this the wrong way to go about getting CWR on the unit? I am trying now to boot into a default CWR SD card and run a fix from this thread hoping thats the issue
http://forum.xda-developers.com/showthread.php?p=11591197
I dont really have a need for the Stock config so putting everything on eMMC for me sounds ideal and am currently trying to get the dual boot config from here running.
http://forum.xda-developers.com/showthread.php?t=959461
Question now is if I get CWR running from the sd card, can i just apply the prep file and load the pre configured installations from that page? Does the dual boot both boot from eMMC? Will I need to format my existing solution to install that setup?
Thanks for any feedback.

HC, as far as I know, is the only rom that does not respond well to cwr installed internally (I have had those issues). If you get an sd image of cwr burned, you can add any flashable rom to that same card and flash it in recovery (install zip from sd card). If you want to play with CM7, do a backup of your HC rom from your sd card, do your formats and flash the gb rom. I think in theory, if you wanted cwr installed internally, you can load a cwr zip on your cwr card and flash it. I have not tried to dual boot anything, so can not offer any feedback.

So I ran the fix permissions and now I can boot into Recovery From Clockwork or boot from the SD card. There are a couple problems, in order to install the dual boot I need to run recovery from the eMMC but that doesnt seem to mount my SD card or I need to adb into the recovery so I can permission something to run, however doesnt seem to have adb running in Recovery and I dont see an option to restart it.

Alright so everything is working, had to format the SD card. Guess CWR SD sets it up as a boot partition so it wasnt mounting, dual booting froyo + HC, just have to figure out the OC kernels now for each.

I've already got my SD card ready to root my nook, and the files are ready to install hc v4 2nd...i can't wait this should hold me over until the 10"ers come down in price

[Q] NooB questions (3 of 4): Can't boot to rom after installing CWR (CM7)

Absolute NooB to the NC here, so please be gentle!
I've got four issues that should be no-brainers but they are beating me up. I've split them into four separate posts to keep things clean.
3. I have CM7 RC4 installed on eMMC (would have preferred to run it from uSDcard but that's another story).
After I got CM7 installed, wireless configured and then gApps installed, I noticed that the uSDcard wasn't mounted. No problem, popped into Setup, Storage and mounted the card.
But this card had been around the block a couple of times, so I figured it would be best to freshen it, partitions and all.
Started ROM Manager and tried to partition the card. But ROM Manager wouldn't partition without installing CWR.
No problem... went ahead and installed CWR, then partitioned the card.
But now I have a problem.
No matter what I do now, I can't boot to CM7 if the uSDcard is installed it boots into CWR. Even if I unmount the card before rebooting, still goes to CWR.
The only way I can get to CM7 now is to physically remove the card, boot, insert the card then mount it manually.
Surely this can't be right.
What have I done wrong?

CWM doesn't work correctly if installed from ROM Manager...

Thanks, danger-rat, for the pointer to CWR 3.0.1.0.
Unfortunately, I flashed it and still have the same problem. No matter what I do, boots to CWR if uSDcard is in place.

Format your sd card in your computer. download the attached sdformatter (found it on these forums somewhere) and use it. it will delete any funky partitions on the card. it sounds like that card has cwm on it, and the nook will always boot SD card first.
Please make sure you take the sd card out of your nook, and put it in a card reader to perform this step. not sure if would work right if you tried it in the nook.
I have had to do this a few times to fix cards that have been modified to be bootable on the nook.

Hi,
The Nook Color will try and boot first from an external uSD card. If there is
a bootable image on it, it will boot from it. Unmounting (but not removing)
the uSD before rebooting does not change if the uSD is detected on
rebooting.
From what you say, if you have your external uSD in the slot, you say
you always boot into CWM - I assume this is running on the external uSD.
It sounds like you need to reformat and possibly repartition your uSD to all
fat32. There are several threads discussing restoring a uSD to a single
large partition.
One of them referenced this tool to run on a PC (I haven't used it)
http://www.sdcard.org/consumers/formatter_3/
This will delete the contents of the uSD, so make sure there is nothing
you want on it!
I have been keeping several uSD cards around, one for flashing from time
to time and one for data and backups.
Hope this helps,
Peter

all you should have to do is flash the cwm zip with the ext4 kernel (cwmr_3.0.1.0.zip) from this thread:

For me all i did was install with Rommanger, then reboot into cwm and installed the zip. works like a charm

[Q] CM7.1 on SD...CWM on eMMC...wanna update to 1.3

Well from following some instructions on here for running CM7 off an sd card I ended up installing CWM that I did not know would go to the eMMC. So I have stock nook 1.2 software and CWM on the eMMC (by mistake), and CM7.1 on SD. I want to remove CWM off the eMMC so I can update to 1.3 and to unvoid my 2 year extended warranty. I have read through threads about returning to stock, but I haven't seen anyone with my same problem using those methods to confirm if it would work in this situation. Everyone seems to have been running some kind of root on eMMC and want to keep cwm. Also with my CM7.1 sd card out I can't get into cwm even though its on the eMMC and I have tried many ways. Do I need to have an update file on an sd card in order to get cwm to run?

Might want to post to the thread for the SD card install.

Use the second file in the first post of the link below. It will restore 1.2 stock and remove CWM from the eMMC. You will have to re-register your Nook.

1. Do I need to de-register my Nook first?
2. Will CWM 3.2.0.1 work for this?
2. If I put the file on a SD card and power on the Nook will it automatically go to CWM?
3. Is the factory reset and option in the CWM menu?

1. Nope.

2b. No. Turn off your Nook. Then press power & the N button together and hold for 5 seconds.
3. Yes.

Actually if you have a separate bootable CWM microSD card (3.2.0.1 should be fine as 416 said) the Nook will default to booting from the SD card when you power on. No need to hold the N button. If the update file (zip format) I pointed to is on the SD card then you can pick it and install from the CWM menu that will come up. (I would make a backup of your current state onto the bootable CWM SD card first and copy the files to your PC just in case.)

EDIT* Ok guys here is my problem now. For the life of me it would not boot into recovery, so I tricked it by trying to install the 1.3 update which goes in CWM but fails. Once in the CwM menu after 1.3 failing I mounted the sd card and tried installing the zip that was on it. When trying to install it says installation failed and something else about verification failed similar to the 1.3 failed. Any help guys?
Would my next option be to create a CWM bootable SD? Anyone have the appropriate link?

Hrm.. seems like that may be beyond my paygrade...
Just to clarify (and sorry I can't be more specific as I just removed CWM, so I can't repeat my steps), when I did it:
1. I downloaded the aforementioned zip onto a spare sd.
2. I booted into CWM (it seems like your trick should be fine, after it gets you back to the main menu).
3. I selected "choose zip from SD" or something like that.
4. I selected choose zip from sd again (ignoring the "update.zip" option).
5. It did it's thing.
6. I selected back several times, to get main menu again.
7. I selected "factory reset" (wipe data & cache)
8. It did it's thing.
9. Reboot and I was good to go.
If that doesn't work, this thread has the instructions on taking it back to stock by creating a CWM card.
http://forum.xda-developers.com/showthread.php?t=931720
Hope it helps.

This is what I did
1. placed the zip file on a sd card
2. insert into the nook
3. power on
4. cant boot into recovery so placed the 1.3 update on emmc to fool it into going into recovery
5. 1.3 update failed but just used it to get into recovery
6. mounted sd card
7. select install zip from sd card
8. chose the file from sd card
9. yes install file from sd card
10. did not get a progress bar like the 1.3 update b4 failing
11. install failed...verification error (similar to 1.3 update error)
The problem with the thread you linked is that its using CWM 3.0.0.5 when the thread about restoring NC 1.2 says it need at least CWM 3.0.1.0

Hrmm... maybe the zip is a bad file? Have you tried downloading it again?
Beyond that, someone with more expertise may need to chime in.
Sorry about the out-of-date thread. It's just the one I bookmarked after I realized I had accidentally installed CWM to my emmc instead of my SD. I never got around to it; dtbrewer's post today seemed like an easier fix.

I got it guys. I used this site to make a bootable sd...http://mrm3.net/nook-color-updated-clockwork-recovery-bootable-sd/
Wrote the image to the sd installed the zip file and now I'm updated to 1.3 on the stock software and my 2 year extended warranty isn't voided anymore. THANKS GUYS!

Posted this in another thread, but thought I'd ask here as well. If you follow the fix listed in this thread, can you use the dual boot sd card and still have B&N 1.3? Or does updating to 1.3 mean you can no longer use the dual boot sd card. What I'd ideally like to have is dual boot from SD, but when I choose to boot to emmc, it will run the 1.3 B&N firmware. Is that even possible?

need help, nook is all messed up--solved

I use the SD card method to have the nook boot into CM7 and when the SD card is pulled, the nook would be stock to be used by my kids. But I think I messed things up and can't restore. Here is what I have done:
1- I tried to update the stock version to 1.3 manually from B&N website but soon realized I could not. It seems like when in CM7, I had tried to flash CWM recovery (which was not needed and is pretty buggy in SD card method for nook). Now the recovery in emmc appears to be CWM.
2-for some stupid reason when I got into CMM recovery, I formatted boot, system,data and cache (not sure if I did boot also or not). My thinking was to flash a stock image and be fixed. But I am now stuck.
Is there a way to go back to stock on the nook? I am still able to boot into SD card and CM7 nightly. Oh ya, I use Linux Ubuntu not windows. TIA

Sounds like you should get the system back to stock before proceeding any further.
Follow the instruction here: http://www.nookdevs.com/NookColor_UnRooting

The problem is that I get into the CWM recovery and not given the reset option following the options on that page. Any idea?
I think my problem is that I'm not really rooted in true sense since I was running off the SD card. Maybe I shoudl root properly, then unroot?

I did kind of the same thing once. I made an Sd card image with CWM on another sd card -- basically as if you are going to install CM7 to emmc. However, once you get to the point where you would flash Cm7, use the stock zip ROM. It will install that to emmc so it will be back to normal. You should then be good to go.

If you follow the instructions you should be left with an unrooted initialized stock Nook Color. Register your account. Then you can wait for the NC to download the 1.3 update, or side load it. Once that is installed you have an unrooted 1.3 stock system.
From there you can try your CM7 card. Don't forget to remove your SD card at the very beginning since like a PC the NC will try to boot off the SD card if it is present.

when I follow the instruction, I am not given the factory reset option. I am stuck at the n screen. It flashed the read forever but then stuck at the n screen. Do I have to wait longer than 5 minutes?

None of this is mine, I owe it ALL to the threads mentioned below.
So as in many posts on XDA say, it's almost impossible to brick the Nook. What a great device. I had to format my SD card to use it to "un-brick" my nook but it was done. I Mainly used the info here http://forum.xda-developers.com/showthread.php?t=949699
Burnt a bootable CWM image onto my SD card. It took a while doing it with dd in Linux. I'm sure it's the same in Windows or Mac. It took about 20-30 minutes. It also took a while to unzip/extract the img file from the downloaded file. Be patient
Then used the CWM recovery remover file from http://forum.xda-developers.com/showthread.php?t=914690 to remove my CWM recovery and used the 1.0.1 file from same thread to flash the stock image onto the nook.
Once the SD card is ready, just drop those files in the root of the sd card. It should have 4 other files in it to boot into CWM recovery from the sd card and let you use the menus to flash those two zip files. It took a while but it's all in those threads. Thanks to the members. Now lets see if I can go up to 1.3 and then root it again.
