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!

I could really use some help, *UPDATE* Thanks XDA....

I don't know where to turn. I started a thread about my effed up nook but it got deleted (my fault) I'm completely at my wits end here. I had NookFroyo .68 working just fine on mine but like an IDIOT I thought it would be neat to try out CM7. Big mistake would not get past the animated N screen no matter what. I got the SD version of the Customized Nook Froyo to boot up but its very slow and stuff doesn't work. How do I get a ROM back on the eMMC? Some one suggested I get CWR and a ROM on the card and flash it via CWR off the card onto the eMMC. How exactly do I do this? I CANNOT get the winimage method to work no matter what I do and I don't know WHAT I'm doing wrong. Everytime I direct winimage to the place I've downloaded an image to, theres nothing there....
I thought I ALMOST had it a few minutes ago. I can get the CWR to come up and I flashed the flashable eMMC NF. I got my hopes up as it started to boot BUT OF COURSE NOT - went into a boot loop, constantly doing the N screen over and over. WTF.
I'm desperate here. I'm at the point where I'm willing to pay someone a small fee to help me get this sorted out. I'm going to keep on trying....

on win image, when you go to select the file. you must change the file types it see's to everything. that will let you see the .img file you downloaded.

We are talking about Win32disk imager right? It only gives the *img selection.

I've heard of an 8 boot reset. How does that work?
I'm reading the "Recovery" thread. Should I do the "repartiion" zip file? I'm starting to think that maybe the problem...
EDIT: Tried the Repartion.zip. No change. Still continously reboots.

I just tried the Nook restore file and it still gets hung up on a different N screen (the Nook symbol). What in the HECK! It wont' go into CWR anymore, says there isn't any room on the card. AN 8GB CARD!!!! I put the card back in the computer and it says its only 115MB! WHAT THE HELL IS GOING ON HERE.
EDIT X2: LOOKS LIKE I GOT IT BACK TO STOCK. WHEW! Now I can start over! Tomorrow after I rest a bit. LOL

Hi,
I found this post (in developers/cm7 users thread) very useful for installing
CM7:
http://forum.xda-developers.com/showpost.php?p=11535969&postcount=151
It is a little dated (weeks) but very detailed and should hopefully still all work fine.
Some more general information on:
http://nookdevs.com/Portal:NookColor
I find that I never have enough uSD cards to use - so make sure that
you have several spare. The emmc Androids are still in general expecting
an external SD card for storing data such as ebooks etc. and CWM will
backup to the external cards too.
CM7 and Froyo use different disk format types for various partitions, don't know,
but that may be part of your problem?
Your PC won't normally read some of the linux partitions on the SD card
either - hence only 115MB showing. This is the boot partition, formatted with
FAT32 (a PC related format) In general you don't need to reformat this partition,
just update or change some of the files. (Some of the names of formats used include:
FAT32, EXT3 and EXT4)
CM7/17 and CM7/19 Have both been very stable and easy to use for me. I switched
to CM7 from Froyo 6.8 a week or so ago.
Good luck, the Color Nook is a fun device!
Peter

Thanks all I appreciate the help. I used some HP utility to take care of the cards, worked great.

Ok I've got a NF .68 up and running. Titanium backup worked beautifully. SetCPU is running it at 1.1 interactive..... HOWEVER!....
I flashed it with a another version of the CWM flashable .68 NF that I had previously. I tried to reflash the other version and it went to install then stated "Installation aborted". I tried twice and got the same thing. I guess its no big deal since their the same version just this one thats on there had some more tweaks hence the title "Customized".
My question is why did it do that? My guess I was supposed to format or clear the data/system/caches' in CWR. Is that right? If so, which ones precisly do I clear or format before flashing a new ROM? I'm starting to think thats' what happened when I tried to load CM7 (Yes I had CWR 3010) and go me all borked to begin with....
And if someone would like to answer a quick question. What this EXT4 stuff and how does it pertain to flashing ROMs? Thanks guys... Your advice got me back up and running!

Always format /system, /data, and /cache. Whatever you do DO NOT format /boot.
As to why you may have had an issue on trying the other ROM. My guess is it has to do with what version of CWR you had been using and wha twas on the device prior to flashing it. I've found if you make say a nandroid backup using 3.0.0.6 or earlier, and are currently using CWR 3.0.1.0 they don't mix well. And I think it has to do with the fact the older CWR version only supported ext3, and the newer one has ext3 and ext4 support. So once you install a ROM using CWR 3.0.1.0 that uses ext4, and then you try to go back to a ROM that is ext3 it just doens't work out like planned.
That all said I not longer flash CWR to eMMC, and I have a bootable sdcard running 3.0.1.0 with all my current and old backup files. Make life much much easier IMO seeing as you can always boot to an sdcard, and all backups are in the correct format and will Restore just fine.

Thanks for the info! I'm sure that will make trying to upgrade to CM7 actually work! LOL!
But first can someone explain to me what this EXT3/4 stuff is?

Different filesystems for Linux/Android. Wikipedia has pages for each if you want google them and get too much info

Too much info? No thanks! As you can see I can barely handle the info I'm getting now!

Need some serious help...

Alright here's my whole story...
Was running Froyo 6.8 flashed to internal memory. Was going to update to latest Phiremod. Booted into clock recovery and formatted system and data. Then went to install the Phiremod zip and it wouldn't work. I forget what it said now because i've been trying so many things. Either way wouldn't go more than a line or two before saying it couldn't install. Now after reboot it won't go past the blue android line in the upper left corner. I can still get into clockwork but now it says it can't mount sd card. Someone please help. I knew I should have left it alone...

Well as long as the hardware itself is ok there should be no need to worry. I wish I had enough experience to help you through this but Im afraid at this point it would be like the blind leading the blind. So just relax and be patient and im sure someone will be able to help get you going again.

Try flashing it again this time also formatting cache and MAKE SURE NOT TO FORMAT /BOOT! Also make sure none of the partitions are mounted. If that doesnt work write down the darn error msg.. oh also redownload phiremod and compair it against the md5

I've had a few instances where the sd card just stopped talking to the nook. Usually just taking it out and reseating it seemed to help. Could be this is the issue with not mounting, either that or the card just needs to be reburned with an image. I would start with just popping it out and back in, and if this doesn't work relfash the image to the card. If I'm not mistaken Phiremod is based on CM7, and you need an EXT4 aware CWR. Make sure you have the right version for what you are installing.

[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] I can ONLY boot to recovery

Hi,
I was happily using my blue-dot NC with CM7 Nightly-177, as suddenly it started to boot ONLY to recovery (CWM 3.2.0.1).
I had used the NC, then put into a neoprene type cover, and put all in a soft bag, and carried it in the car and when I wanted to power the NC on, I was in recovery..
SDCard was intact, could read and copy the contents in my PC.
Tried everything including trying to install CM7 from the sdcard anew multiple times.
It boots from the sdcard, I wipe data, I wipe cache, I wipe dalvik cache, I find and install zip, I install gapps, everything goes OK.. I power down, take the sdcard out. I powerup.. I have the green logo, then the recovery...
What could I be doing wrong?
I'm really pissed off, and thanks for any help.

I wouldn't have wiped data. (I hope you have a backup.) Since it will boot into recovery off the eMMC, put a nightly on a non booting SD card and try again and only wipe Davlik. Normally when updating with ROM Manager that is all you need to wipe. You also might want to flash the gaaps .zip again if you find the market missing after you get back into CM7.

Seemed like you flashed ROM manager into eMMC.

Yes, multiple times with different zips..
It is always, the green Cyanogen logo, says loading, a little flicker, and the amber menu..

That is very odd. Possibly you have a corrupted image on your card. Have you tried creating the bootable image all over again?
Dumb question..... is it fully charged?

I will try reverting to stock, and then install once more. If not, I will try to boot from the sdcrad (double boot).

Before trying once more I want to check with you which image, which nightly, and which gapps should I use, and maybe from where to download..
I have a 4 GB Sandisk sdcard.

Do you want to install CM7 to the internal memory (eMMC) or just running it off the uSD?
You have to know what you want to do first.

Of course I would like to install to emmc..

I assume you have a brand-new (or like brand-new) v.1.2 NC and you don't want to deal with its partitions.
1. I never try that 3.2.0.1 from eyeballer, but it should be good. Just make sure you not get the corrupted one during download
2. Get the Win32DiskImager old version, r0.15 or something
3. Create flashable uSD (i'm sure you know how to)
Make sure it's good (there should be 4 files in the boot uSD)
4. Get the stable CM7 7.1 and the latest Gapps (0811 or 0821)
5. Drop both in the uSD
6. Fire the NC up.
7. It should get into the CwM R, from there
a. format /system
b. format /data
c. format /cache
Note: I didn't format /boot when doing mine.
d. install CM7 first
e. then install Gapp
8. perform wipe data/factory reset
9. after done, remove the uSD before reboot system.
Give it some times during the first boot.
If after 10' and still not up, then force reboot.
Keep fingers crossed.
