Dual Boot Full Android and Android TV on Shield TV
Boot Android TV or Full Android from USB Disk
I was looking for the easiest way ever, and it is this.
The step by step procedure:
1) Format an USB HD or USB 3 Flash Drive as primary Ext4 partition with Linux. You can use Gparted tool.
2) Mount the USB drive with Paragon extFS: https://www.paragon-software.com/home/extfs-windows/
3) Download stock recovery firmware from Nvidia: https://developer.nvidia.com/shield-open-source or Full Android: http://www.videomap.it/forum/viewtopic.php?f=25&t=1580#p3030
4) Extract system.img and vendor.img from stock recovery firmware or from full Android archive
5) Convert system.img and vendor.img to ext4 using simg2img.exe tool: https://github.com/KinglyWayne/simg2img_win
6) Download su.img from here: https://goo.gl/Jo8mus
7) Copy system.img, vendor.img and su.img to mounted usb drive
8) Attach USB drive to Nvidia Shield TV
9) Download the boot / recovery image satv_boot_from_usb_1.1.img from here: https://goo.gl/vGosks
10) Reboot Shield TV to Fastboot mode
11) Flash the satv_boot_from_usb_1.1.img as recovery with the command: fastboot flash recovery satv_boot_from_usb_1.1.img
12) Switch from PC screen to Shield TV screen and with the Shield TV power button long press on Boot Recovery Kernel
13) Shield TV will stuck on Nvidia Logo
14) After short time, if you don't see the Android boot logo, remove the power cable
15) Reboot Shield TV to Fastboot mode
16) Flash the satv_boot_from_usb_1.1.img as recovery with the command: fastboot flash recovery satv_boot_from_usb_1.1.img
17) Switch from PC screen to Shield TV screen and with the Shield TV power button long press on Boot Recovery Kernel
18) Now the Shield TV will boot well from USB and the disk will be initialized in the right way
From now on, every time you reboot in recovery mode from the main OS you will go to the second OS that is installed on the USB drive
