I tried following this approach:
The initial image with CWM 5.x worked fine, and the Nook rooted fine. I installed ES File Explorer, launched the Nook recovery Flash.apk, fine
Installed CWM 6.2.7 fine.
Final Step - Went to install the last stable release of CyanogenMod (cm-10.2.1-acclaim) and the screen flashed several times, then went off).
I powered it on and it stuck int the "Read Forever" white screen.
I can get it to go into Recovery mode by booting off the micro SD Card image I first created, and can even get it to CWM 6.2.7. But that's it. I can't get it beyond recovery mode, or rebooting into the "Read Forever" screen.
As a last resort (and maybe not a bright one?) I tried restoring back to factory defaults..... To no avail. No change in behavior.
After downloading some earlier mod versions (i.e. 10.1.3, 10.2.0, etc) I did manage to get the Cyanogemod bootloader to install. However, I could not get past the initial boot screen (where the Arrow circles the face).
I tried installing different versions of the Mod (even successfully installing 10.2.3 which I initially had problems with). I tried wiping the cache, and the Dalvik cache and rebooted, as well as trying wiping them, installing another cyanogenmod and restarting, and to no avail.
So, I can get to recovery screen, and I can get to the bootloader screen, but no further.
And all this, because Netflix stopped working on the original 1.4.3 B&N firmware (sigh).
Really appreciate some help here.
