How did you even manage to compile the old version?
I tried to cross-compile 8.95.003 using the command PROJECT=Allwinner ARCH=arm DEVICE=A64 UBOOT_SYSTEM=pine64-plus make image. But this just gave me this error: ERROR: Project not found, use a valid project or create a new config.
For the newest LibreELEC the compiling works like charm, but still gives me an image with Kodi19.
But like you, I'd like to have Kodi18 for plugin compability until most devs updated their plugins.
So, how can we compile LibreELEC 8.X (or 9.2 with Kodi18) for the A64plus? I'd do it native on the board, but I don't know how.
EDIT:
I managed to get 8.95.003 to start compiling after copying the /projects/Allwinner folder from 9.2. Compiling did well for like 30 minutes, then stopped to prompt me for files to patch.
