Installing Latest Openelec 7

[Stormbreaker]

Hiya Folks,

Hope you can help me

Ik have a Eminent 7580 Tv Streamer box.
Some info of the box:

Openelec 6.95.2.70 / Kodi Jarvis 16.1 RC
Chipset: AMLogic S805-H with Dolby and DTS, Quad Core Cortex 1,5GHz
GPU: Quad core Mali-450MP

I want te experiment a bit, for example installing the latest Openelec 7 beta with kodi 17
or atleast the stable final version of openelec with kodi 16.1.

I have access to the box using SSH

Is that possible? if so wich image file do i downloade?

Thx for you help
