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 eg. the preinstalled user app Chrome does (Z9S with firmware v2.3.33. It might be differ on your player).
To modify the system partition of your device it has to be rooted. For this task download listed applications:
Download the APKs and put them on a stick or in the download folder of your player’s internal storage.
There are several ways to install an APK eg. double click on the APK in the Media Center. With the app ApkInstaller you can install several APKs at once.
ApkInstaller scans your system for APKs, so you might have to deselect what you don’t want to be installed
press the Install button
execute OnekeyRoot and follow the instructions on your screen
after reboot your device is rooted
execute Terminal Emulator
change from role user to superuser
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
but here under system
The Home Theater app is still on the system partition
change to system app directory
list all directory starting with zidoo
ls -ld zidoo*
force recursive remove of directory zidoo_poster
rm -rf zidoo_poster
The system partition is read only by default so just removing the folder zidoo_poster will fail. To get write permission on the system partition it has to be remounted
mount -o remount,rw -t yaffs2 /dev/block/mmcblk0p1 /system
now you can remove the folder zidoo_poster from system partition
rm -rf zidoo_poster
Home Theater has completely remove from your device
Reboot your player

Hi. I’m trying to uninstall the Hometheater apk but I do not know how to manage or control Terminal Emulator. How do you manage to control the app? I managed to install it but when I run it opens but I don’t get how to control it.
