On Android there are system apps and user apps. System apps are stored in the system partition and user apps in the user partition. For security reason, you cannot alter the system partition as a user. That is the reason why a user can not uninstall system apps. The app menu for Home Theater, Music Player or Media Manager don’t show the uninstall button like e.g. the preinstalled user app Chrome does (X9S with firmware v2.1.45. It might be differed on your player).




As precondition, please read the guide “How to use Android Debug Bridge” first.
adb start-server

adb

interactive shell
use the package manager to list the installed Zidoo packages with their package names
pm list packages | grep zidoo

use the package manager to uninstall Home Theater with package name com.zidoo.poster
pm uninstall --user 0 com.zidoo.poster
pm uninstall com.zidoo.poster

Home Theater is no longer listed under APPS

or Settings ➛ Apps

but it’s still listed under Settings ➛ Apps ➛ Show system


The Home Theater app is still on the system partition, so it has to be removed permanently.
change to system app directory
cd /system/app
list all directory starting with zidoo
ls -ld zidoo*
force recursive remove of directory zidoo_poster
rm -rf zidoo_poster

Reboot and Home Theater has completely removed from your player
