Yes, some user have the same issue. According to them this is due to the new firmware update from TM will auto remove the playstore and block any installation.
This is maybe due to high customer request on warranty or to solve problem when they messed up their box. 

Meaning the box is useless d except watching hypptv....haiz....

I have the same problem

ENABLE UNKNOWN SOURCE APK & INSTALL APK TO HYPPTV WITHOUT ROOT!!!

Hi Guys,

I have created a little app to install unknown source APK into your HyppTV box! I have posted here https://forum.lowyat.net/index.php?showtopi...&#entry72787204 originally but think more people will notice if I open a new thread.

Steps:
0) MAKE SURE YOUR POWER SUPPLY IS ON FOR THE WHOLE PROCESS OR ELSE WILL SPOIL YOUR TV BOX
1) Copy the attached HyppTV-APK-Installer.zip [attachmentid=4328289] to your USB drive.
2) Plug USB drive into your HyppTV box.
3) Power off your HyppTV box by plug out power cable.
4) Press your remote control RED power ON button and hold it till step 6.
5) Plug in power cable into your HyppTV Box and press the power button behind the box.
6) When you see white HyppTV welcome screem, you can release remote control RED power ON button.
7) You will see a black screen with a Android robot.
8) Use remote control UP/DOWN to navigate to "Apply update from external storage" and press OK button.
9) Choose HyppTV-APK-Installer.zip and press OK.
10) Wait for system to reboot and when start just run HyppAPK.

This little app will try to enable "Unknown source" apk installation, if set successful, it will fire up a simple file explorer for you to install APK. This app MUST be install as a system app for it to work (follow the 10 step above). As far as I know, no root is require.

Thanks akifrabbani for doing a great job to start all this! Without him, I will be so disappointed with HyppTV Box which cannot install APK!
