Bricked Mah Nook!

I know, its not truly bricked. But as of right now it'll only power up if connected to USB power source and will only boot as far as landscape Android text with a blinking underscore. Part of why I didn't get it fixed last night was my unwillingness to leave and aquire a larger micro SD card. I'll be leaving work in a couple hours to go get some stuff to get this thing working again (its 2 days old) heres the recovery plan:
Aquire 4GB + MSD card
Flash a stock 1.1 ROM (the one thats pre-rooted here)
Install (sideload) that stock joint
Read that Elephant book that comes with the Nook because its working again
From there I'm a little confused. Can I flash Clockwork to a MSD and then use that to flash CM7? Or am I oversimplifying here?

From my trial and error the only thing I have gotten to "un-brick" is to boot into monsters pack then switch cards (i used the 128mb version and it removed the rest of the space on my 2gig card) then format cache and system in the mount section of clockwork. then head to install zip and installed a complete restore to 1.0.1. when thats done I head to BN site and got the side load to 1.1.whatever and let it do its thing. From there your up to date and just like new and can then try and "re-brick" it. Ive had mine for less than a week and done this a few times now cause I am never satisfied.........

The nook is never bricked unless it has a hardware failure. One of the great things about the nook is that it has a very early hook in the boot sequence that checks for presence of a bootable SD card. Creating a bootable SD card is easy. Follow the thread which instructs how to make a CWM bootable SD card. You need to choose between the EXT3 or EXT4 version depending on which ROM you will flash. CM7 requires EXT4 version of CWM. If you try to use the wrong CWM version you will get the outcome that you just observed, stuck at android text. If you want to flash the stock 1.1 rom, then you'll need the CWM EXT3 version.

I had the exact same issue. I used this:
The internal CWR workaround is ugly to say the least. So if you NC should refuse to boot or bootloops, which I hope won't, flash this boot repair that I'm adding just in case. Just flash it, no need for formatting.. Use a bootable CWR SD Card.

That makes things much clearer for me. I knew CM7 required EXT4, but was unaware that the CWM flashed MSD would be properly formatted and couldent be bothered to boot in Linux to do it. Blame lack of sleep. Thanks!

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

CM7 Build for CWM(internal)

All I see are instructions on how to use ADB or to use CWM to flash to the external SD. Is there a way to use CWM ready CM7 for the internal flash?

Hi,
If I understand your question, you would like to run CyanogenMOD7 off the
internal memory also called emmc, rather than running it off the external
memory or uSD card.
Though a bit dated, I found this walk-through to be very detailed:

Hope this is what you are looking for.

It is helpful, however I am looking for a CWM ready version....so far no luck.

Hi,
The instructions in:
http://forum.xda-developers.com/showthread.php?t=960542&page=16
Are assuming running from uSD version of CWM.
Following other CWM install instructions you can end up with CWM installed
on the internal flash, emmc.
For example:
http://forum.xda-developers.com/showthread.php?t=971197
Minor issue to watch for: the versions of CWM that support EXT4, required
for CM7 also require a different kernel.
I'm not quite sure what you mean by CWM ready version of CM7... the CM7
nightlies are in a .zip file that is flashed by CWM running off the EMMC boot
partition. The first time you install CM7 you also have to use CWM to
reformat some of the partitions on the EMMC (to ext4), but after that you can
use CWM to update the flash each time.
ROMManager can also be used to download ROMS and start CWM.
I am in 'updating' mode, I usually download a recent CM7 nightly and
recent overclock Kernel on PC, then share to Nook using Dropbox.
On Nook, I download .zips from Dropbox and move to root of the data
SD card. I also have latest Google apps (GAPPS) in Dropbox or SD card.
I then use ROMManager to run CWM to backup entire ROM.
Then I use ROMManager to boot into CWM and individually:
Install from .zip: nightlyxxx.zip (Current CM7 version)
Install from .zip GAPPSxxx.zip (Current google apps version)
Install from .zip kernelxxx.zip (Current OC kernel, overwrites the CM7 version)
Then I wipe cache partition.
Then finally wipe dalvik partition - CWM freezes here.
Reboot and wait a while (5 mins) (I assume it is rebuilding dalvik cache here)
Often seem to need another reboot and wait.
Hope this helps...

Thanks, that does clarify things. I'm new at this and do it was a little confusing to me how to do it. In the captivate forum they're a little more forward on how it's done. I appreciate the help. I tried using the rc4 encore signed but it seems to stop at the startup with N color on it. I thought I formatted all the partitions properly. Is there something I did wrong?

Hi,
I haven't had the problem of being stuck at 'N', but I'm sure there are plenty of
others that have... it will be something simple, probably missed one step in install.
Perhaps check through the list you followed and try and remember if you forgot
one step, or didn't understand one of the steps.
My install no longer shows the "N" at all when booting, so I'm guessing that
there is a missing piece somewhere!
I get:
"Touch the Future of Reading"
Brief flash of "Loading"
Few seconds of sideways "android..."
Then an animated CyanogenMOD logo for more seconds.
Here is one (long) thread about booting problems, but there are other ones too.

Hope this helps,

Got the problem fixed. Had to boot to a different CWM and format as ext4. Now all is well.

Speed Comparison
I have CM7 flashed to a class 4 sd card and it seems a little slow compared to the stock elcair build. Does CM7 installed to the internal memory speed things up a bit or does the system still seem a little slow. I'd like to know before I flash to my internal memory.

It should be faster on the internal, logically speaking, but perhaps with the right SD card you'll get comparable speed.

[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

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.
