[Nook HD, HD+ Q&A, Help & Troubleshooting] nook2hd:
My Nook HD+ 32GB will only boot into CWM, did I brick it?

Let me trace back the steps that got me into this mess:

1) I had CM10.1 running ok, and felt adventurous to try CM10.2 yesterday. I downloaded cm-10.2-20130904-NIGHTLY-ovation.zip from http://download.cyanogenmod.com/?device=ovation, and installed ok.

2) Noticed Kindle app crashes as some people reported in CM10.2, also noticed that clock app stopped. So decided to go back to cm10.1.

3) Downloaded cm10.1.3-RC2 and installed it from CWM without wipe data (forgot that time, normally I do that step before install a ROM). After reboot, it hung at the Cyanogenmod circle.

4) So I booted with a SD card that was created from emmc-cwm-early2.1.img (from http://xdaforums.com/showthread.php?t=2263553), trying to reinstall cm10.1.3-RC2 into a clean slate, and being too brave, I went into the "mounts and storage" option, formatted all the partitions one by one, including /rom, /system, /bootdata, /mmc, /cache, /data. My guess is that I did too much damage at formatting.

5) Then I installed cwm-recovery-ovation-2.zip first, then cm10.1.3-RC2 and gapps. The installation seemed ok. However, when I took out the SD card and reboot, I will see nook sign, then cyanoboot sign, then get into EMMC CWM-based recovery v6.0.3.2.

6) Tried to boot 8 times, does not seem to help, still can only boot into CWM.

7) Went into the "mounts and storage" option in CWM, noticed that only /cache and /data are mounted, and I don't see /rom partition listed. Without SD card in the nook, I can mount /bootdata and /system, mount /sdcard will report "Error mounting /sdcard!", mount /mmc will not report anything, but the status is still unmounted.

8) Fresh boot into CMW, and go into advanced -> show log, here is what I get:

net.bt.name=Android
net.change=net.bt.name
dalvik.vm.stack-trace-file=/data/anr/traces.txt
init.svc.ueventd=running
init.svc.recovery=running
service.adb.root=1
init.svc.adbd=running

I: Checking for extendedcommand...
I:Skipping execution of extendedcommand. file not found...
I:Can't format unknown volume: /external_sd
I:Can't partition non-vfat: datamedia

If I tried to mount /emmc first and come to show log, I noticed that there will be an extra line:

I: using /data/media for /emmc

before

I:Can't format unknown volume: /external_sd
I:Can't partition non-vfat: datamedia

If I tried to mount /sdcard first and come to show log, I noticed that there will be a few extra lines:

W: failed to mount /dev/block/mmcblk1p1 (No such file or directory)
Error mounting /sdcard!

before

I:Can't format unknown volume: /external_sd
I:Can't partition non-vfat: datamedia

9) When reboot system now from CWM, it says "Root access is missing. Root device?" Choose yes or no does not change the effect that Nook HD only boots into ENNC CWM.

10) My problem bears some resemblance to what reported in http://xdaforums.com/showthread.php?t=2221289, but apparently different.

11) Before I find a fix, I was trying to use CM10.1 on SDCARD following http://xdaforums.com/showthread.php?t=2087988. I have a SanDisk 32G card (not recommended SanDisk U1 card), but after WIn32DiskImager wrote the image to the card, the partition is too smalll to even put the cm10.1 sdcard zip file on to it, and I don't think I have access to the internal sdcard right now. So running cm10.1 on sdcard won't work for me either.

Please help me find a solution, the preferred situation would be to running cm10.1 on emmc as I had before.

Hope I provided enough information for you to decipher the problem.
