I am new to android stuff, and I am trying to root my nook color 1.4.2 by following
from above guide i am unable to find how to do a complete wipe for nook color 1.4.2 so I followed
although its not for 1.4.2, may be to this reason I am unable to do complete wipe nook color 1.4.2.
Also I followed all steps to create a bootable SD card from the 1st source
but unfortunately I am unable to boot nook color from SD card, hence I am not able to root my nook color
