Since the old Nethunter page with the process is gone to do a manual install I figured I'd repost this here on how to do a manual install using Kit-Kat not Lollipop for compatibility with adapters that don't work past Kit Kat.

Alright I'll run down the whole process for you (assuming windows installation)

1.) Download and extract the stock google 4.4 image from here https://dl.google.com/dl/android/aos...y-b1b2c0da.tgz and follow the process to restore it to this image https://developers.google.com/androi...s/images?hl=en

2.) Download the KitKat Nethunter version from here http://images.kali.org/kali_linux_ne...zor_kitkat.zip

3.) Follow the steps on the Nethunter prepare page http://www.nethunter.com/prepare/

4.) You shouldn't need to install TWRP as wugsoft's nrt software should for you.

5.) Drag and drop the Nethunter kali image to the root of your sd storage

6.) Boot into TWRP using the TWRP bootmanger app you'll have to snag from the play store

7.) Follow the rest of the install steps http://www.nethunter.com/install/

8.) Wait for it install and reboot

9.) Open a Nethunter shell and run
Code:
apt-get update && apt-get install
apt-get upgrade && apt-get dist-upgrade
10.) Should be able to see your TL-WN722N if you power off plug it in and power back on under iwconfig

11.) You'll need to download pciutils to use monitor mode which will be
Code:
apt-get update && apt-get install pciutils
12.) Test it by running
Code:
airmon-ng check kill
airmon-ng start wlan0
wash -i wlan0mon
13.) To resume normal services
Code:
airmon-ng stop wlan0mon
service network-manger start
Hopefully this should get you up and running, just remember unplugging the otg or adapter while the tablet is on will reset the device.
