Install KODI on a smart box with ANDROID 4.2

Dear community
i am very glad to be here.
I buy a Movie Cube F400 from EMTEC – TV Box with android 4.2 on it.
It works to install Kodi 14.2 on it. It seams for the new Krypton version it doesen*t work with my software of Android 4.2.
On this version of Kodi 14.2 – i can`t install the newest Add-on´s for example. It sucks!
Can somebody help me to install the latest version of Kodi that works on Android 4.2?

Or better asked: what software of Kodi are compatible with Android 4.2 ?

Exists any software update possibilitys for my EMTEC-Movie Cube?

Thanks a lot for any help
