Converting a nook color into a Jellybean 4.1 tablet.  I think it took me longer to write this up than to actually do it 🙂

Done on Linux Mint – bash commands are showing in bold italics

1. grab a microsd card – they say that Sandisk brand, at least Class 4 works best.
   I have done this with both a 4GB and 8GB card, both worked, you can go larger – I am not sure if there is a max capacity supported by Android or the nook
2. Download the boot image – http://forum.xda-developers.com/showthread.php?p=32921666#post32921666
   Look for the attachment to the main article – generic-sdcard-v1.3-CM7-9-10-larger-Rev5.zip
   I get a md5sum of : a2f15e48a5bb858db8ec02ccedbcb5b7
