This has already been asked by another user, and unfortunately this is still my suggestion:
Ok.
I have installed CoreElec 9.2.8 on Mecool KIII very long time, with some specific service like ZeroTier, TVLINK (Python 3.11), etc which ones have been installed via entware.
I tought to replace this CoreELEC with your LibreELEC, due to leak of support for this old CoreELEC, and you still work and issue update of LibreELEC which work with internal dvb tuner.
Thanks for reply.
