Jelly Bean on a Nook Tablet

Because so many people ask and are confused on how to boot a Nook Tablet (NT) using an SD card....Oh and a similar process works for the Nook HD+.

Make the NT rock and install Jelly Bean boot via microSD in 10 easy steps:

1) Format a good SD card of at least 4GB in size (A good SD card should have a formatted Crystal disk 4k QD32 write of 1 or greater.) Sandisk class 4 cards have been shown to be consistently good. I found the 16gb G.Skill class 10 cards from newegg were great - QD32 1.4.

2) Download the rather stable cm10-121208_acclaim_sd_hd_img.rar and extract the image file using 7-zip. Additional roms are available: CM 10.1 Jelly Bean  and CM10.2 Jelly Bean (shown)

3) Write the extracted image to the SD card using win32diskimager. Make sure you are writing to the SD card and not to some other portable drive or SSD on your PC!

4) Open MiniTool Partition Wizard  and you should see your PC's partition(s) (leave these alone) and 5 partitions including the unused partition on the microSD card.

5) Delete Partition 4 (Fat 32 SDCARd) and hit Apply

6) Delete the Other partition ~600mb and hit Apply (Neither of those two partitions had any files in them. DO NOT delete the 1st or second partitions which both have the necessary files already inside.)

7) Create a new partition called DATA and select Primary and Ext 4. Make the size 1-4GB (or more) depending on app usage. This is where apps will install. It you are an app hog, them go with 4GB. I went with 2.5GB. Hit Apply.

8) Create a new partition called SDCARD and select Primary and FAT32. The size should be the remaining card space by default - leave it this way. Hit Apply.

9) Close the Partition Wizard, remove the microSD card and place it in the NT that is currently turned off (it needs to be off and not in the sleep state).

10) Turn the NT on and welcome to Jelly Bean. (If you reboot it will go back to stock NT. If you turn it off and then on it will boot Jelly Bean.) Enjoy!
