Here is my community build. Kernel is build as 64bit with 32bit Userspace. It means you can use 32bit armhf packages.
I'm putting it here too. You can also get support here:
Wetekforums for WH
Wetekforums for WP2
Odroid Forum for C2
DISCLAIMER: It's a community build of LibreELEC. USE AT YOUR OWN RISK! Report Bug only to me.
Tar upgrade from aarch64 might work use the following steps:
Then copy the tar into /storage/.update/ and reboot
After everthing is updated you need to remove all the binary addons and reinstall those from the repo.
Beware that kodi caches zips in /storage/.kodi/addons/packages. Those have to be removed too.
If you are updating from one of my previous builds you just need to put the tar in /storage/.update/
LibRetro, DRM with inputstream work.
It is bleeding edge. I'm following LibreELEC release cycle.
