[Barnes & Noble Nook Tablet] rp201:
I had some free time so I thought I would upgrade my nook. I had read some issues with sideloading 1.4.1 and using adb so I stayed on 1.4.0 until today. I also wanted a freshstart but more of a migration. To follow what I did today you will need the following:

titantium backup installed on your 1.4.0 (purchase the app)

micro sdcard installed to hold your backup apps

an empty 2 gig or greater micros sd card to root and install gapps

root explorer installed on your 1.4.0 ( you can choose to install this after rooting if you wish)

sqlite3 installed on 1.4.0 (you can choose to install this after rooting if you wish)

reasons why I updated and was happy after the fact.

1. heard better battery management.

2. 5% processor boost. (quadrant standard of 1786 before 1896 after)

3. had lots of crap and residue

reasons not to go to 1.4.1 and stay on 1.4.0

(I will fill this in if they come up)

Please read through all steps first. if you do not understand everything and feel confident then take the blue pill and go back to what you were doing before reading this post.

step 1: backup up applications.

using titantiumbackup, back up all apps you wish to keep and update backups of apps already backed up! do not backup and restore everthing and especially not system apps. don't forget to look for titanuim backup icons (their names are all green) and select "Wi-Fi access points"

remove sdcard of your backups and data from nook and power down the nook.

step 2 factory reset of 1.4.0

make sure your nook is charged to 20% or better.

while nook is powered down, hold both volume up and down buttons at the same time and keep them held as you you hold down the power button down also for 8 seconds. you will see the screen go black and the nook powers down at the 8 second mark. repeat this process 8 times then do a standard power up and allow image to reset fully and reboot.

step3 register with barnes and noble to receive update ota.

this could take some time to receive the update so what I did was use my pc and go to barnes and noble and log in.

http://www.barnesandnoble.com/u/Software-Updates-NOOK-Tablet/379003187/

there I copied the 1.4.1 update file to my pc. do not unzip the file. Now, without an sdcard in the nook, I plugged my nook into a pc and without changing the file name I copied the "nooktablet_1_4_1_update.zip" to the root of the nook. after the file is copied disconnect nook from pc and let it go to standbye mode. this is when it applys the update. takes a minute or two for process to start automagically. you should now be updated to 1.4.1

step 4 rooting and installing google apps.

I followed instructions here:

all they are basically asking you to do is download 2 files.

1 file is the image creator you will use with 2gb empty sdcard. the other file "Gapps_and_root.zip" you copy to the created image root of the 2gsdcard for installing root and google apps. so place card in nook tablet, boot it. it boots into cwm and apply zip file from sdcard called "Gapps_and_root.zip" use the volume up and volume down to go through the menus. use the "n" button to select. and use the power button to go back in the menu while using cwm.

step 5 your device is now rooted and on 1.4.1 and we will begin restoring apps.

press the n button once and select search. seach on "market" and launch the market app. login to the market and download both titanium backup and licensed titatinum backup app. if you did not purchase "root explorer" do that now. if you did not backup sqlite3 with titanium, do that now. Use titanium backup to restore your apps, wifi settings etc and root explorer and sqlite3.

step 6 enabling sideloading of apps.
