I’ve just installed the first beta of OpenELEC 7 a.k.a. 6.95.1 with Kodi v16 Jarvis on my Cubox-i and RPi2. The Tvheadend service was updated and worked straight out of the box, unfortunately the client does not due to mismatching API versions. Following the steps outlined in this thread, i managed to compile an updated version:

docker build

mkdir -p ~/openelec/builds
docker run -it --name imx6 -v ~/openelec/builds/:/builds damonmorgan/openelec-dependencies /bin/bash
cd /builds/
git clone -b 6.95.1 https://github.com/OpenELEC/OpenELEC.tv.git
cd OpenELEC.tv
PROJECT=imx6 ARCH=arm ./scripts/create_addon pvr.hts

Go and grab a huge can of as this is going to take a loooooooooooong while:

  CREATE ADDON  (imx6/arm) pvr.hts
*** compressing Addon pvr.hts ... ***

Just in case you don’t want to wait that almost 1.5 hours (on a really capable machine), i’ll provide my zip for you guys: pvr.hts-2.2.14-armv7.zip. It works (tested here) for all ARMv7 cpus, including Cubox-i (Freescale i.MX6) and RPi2.
