I've got NT 8 Gb with CWM and used Hard reset to brick my NT.
Now I'm able to boot BETA-1-4-2UbuntuRecovery4GdiskAdamOutler.img from SD (appears "n" screen and then "box" image), then black screen for 30 mins and Power Button for 10 sec. (I'm assuming this part works by cable indicators ). Then I took out SD from Nook.
But the screen simply won't turn on and nothing happens when I press Power buttton or Power+"n". No "n" start screen, no 1.4.2, no recovery.
So I can't load from internal memory as someone above mentioned but able to load from SD.
Waiting to hearing from you)
that i pretty much the same for me.
