Here are Generic S905 (semi official1) builds from LibreELEC. They include what we have at GitHub - LibreELEC/LibreELEC.tv .
They get updated for the LE9.0.x release cycle and all add-ons are available at the repo.
These builds are provided without official support. If they work for you thats great, if not you could ask at this thread but don't expect bugfixing (just if there are easy fixable problems).
Install to nand/emmc:
this is script is known as problematic and has known major problems, but it works most of the times
wget http://cvh.libreelec.tv/AML/S905/installtointernal is reported working (for at least kvim)
chmod +x installtointernal
Updates from 7.x/8.x community images are not working - you need to do a fresh install !
1 we (LE) don't official support these builds at our site due the nature of the rather wacky 3.14 codebase, these builds have their flaws but works in general okay
an deeper explanation why we don't offer official support for it and what could be expected for LE9.2/LE10 could be read here Development Update .
