With the Openelec v7.90.009 for Odroid-c2 the PHP not longer runs
openelec? 
For libreelec I will rebuild it as for RPi2. Need a day.
Update: Nope, my build machine is still i386 based and can't run 64 bit binaries which are used by Odroid. Maybe after new year when machine will be reinstalled (if time permits).

You need to go to addons, select LibreELEC repository, select PVR clients and install this addon. Then you need to configure it (set m3u8 playlist). After that you also need to enable Live TV. Reboot after all this could help too.
On Xtreamer Ultra HTPC suspend mode works as it should. And it can be resumed with IR remote.
I can build it but support has been ended 
Which LE image are you using?
If they are dead they are dead - you can't repair them.
Where does the calibration addon writes the coordinates?
I think
/storage/.kodi/userdata/addon_data/service.touchscreen/pointercalNo need to copy extra files anymore - everything is already included
PROJECT=... ARCH=... scripts/create_addon touchscreenTouchscreen addon is also build and available from LibreELEC repository and there is no need to compile it anymore. But it still needs to be manually configured as before.
Seems not all can be pleased - according to one forum post
It looks like CEC got fixed. It seems this release is gonna be the first time I'll use this Cubox-i without an issue.
You can try image with 3.14 kernel because there is different implementation.
And what happen if you scan for devices on TV? Does it detect cuboxi/kodi?
You are using unsupported distro (linuxmint) and some packages are missing. Because those packages (gperf makeinfo lzop ...) can't be installed automatically from a build scripts you need to install it by hand on your system. And then build process will work.
Install those packages by hand?
Seems you will have to figure few things yourself - I can't support things directly which I do not own or have some direct access.
No response from them on my questions previously when OpenElec will be updated.
Bad company then 
Maybe they provide some newer device with updated kodi.
Manually stop all extra services and check how much time it take:
systemctl stop some_service7.0.2 release has similar samba config - no /storage/.kodi exposed directly.
Like I wrote above: if you want to see other folders you need to adjust samba.conf. Or use ssh console.
/storage/.kodi folder is not visible with default samba config. You can see what is visible and which paths here.
If you want to see /storage/.kodi (or /storage or even /) you need to add new share. Or use ssh console where you can see everything.
Ask Xtreamer? They are good providing builds but no sources are disclosed.
If you see udoo in it's name it is for Udoo system. The other is for solidrun's cuboxi and others.
