none work?You need to elaborate a bit more on what's the error?
did u read from start ? did u see the context of that reply "none work?" ?
the error message is on thread start 
but i've solved, reinstall from scratch LibreELEC (503) and restore the settings backups from previous OpenELEC (413) kodi
i've try the
Manual Update from OpenELEC (.tar) -> RPi2 and RPi3 (Combined) Build
none work !
even the Last OpenELEC Millhouse build
/dev/mmcblk0p2 13.5G 473.7M 13.0G 3% /storage

Try downloading it again then try the update again.
