I have got a Samsung UE 55 TU7022KXXH Crystal UHD 4K Smart TV (firmware ver. 213.3) and the mentioned application works perfectly.
A simple Philips FM08FD70B/10 Pendrive was formatted to FAT32 by using Windows 10.
Downloaded tizen.zip was extracted to the root of the pendrive. (Mentioned folder was appeared.)
The pendrive was pluged into the TV and a notification was appeared on the right top corner.
Installation was finished successfully and EMBY application was appeared in the HUB of the TV.
