Just installed today’s nightly. Reboot to Coreelec ATV app still works 
It has a slight freeze on splash screen at 1st time but it worked.
I applied dovi.ko from CE-NG Dolby Vision (+FEL) for DV-licensed SOCs (s905x2, s922x/z, s905x4)
Sometimes my LG CX switches between HDR and DV while seeking through a FEL test file, it didn’t happen on older ATV. Is there a new dovi.ko file which could fix that or it doesn’t matter?
I see someone pulled it from ATV14 and it has different size Homatics Box R 4K Plus - #5462 by hungphutho
