To set up a Vestel MB400 Android SoC screen with embed is easy.
First, you will need:
a USB stick
the latest embed arm64 Android apk loaded onto the root folder of the USB
With your USB stick ready, connect it to the Vestel screen and then turn on the screen.
Next follow these steps for the initial installation process:
Choose your language
Pin - is not needed so you can skip
Select Signage settings > Next
Auto Launch > set to Disabled (we will change this to embed later)
Display operation mode > landscape or portrait (cannot be set later so be sure to select correctly here)
Power mode > Eco
Network settings > Connect to network (choose wireless or wired network)
With this initial setup complete you will now see four options:
[ HTML5 CMS Launcher | Media Player | Signage Settings | Applications ]
Select 'Applications' and follow these steps:
Select 'App Installer'
Select 'USB' to scan the attached USB
Select & Install the embed arm64 apk
Once installed press the Back button to go back to the four options. Now select 'Signage Settings' and follow these steps:
Controls > No Signal Power Off > OFF
Power up settings > Auto Launch > Select Application > select embed
Finally, reboot the screen and it'll now auto launch embed :)
