I am trying to build my own custom Cyanogenmod ROM for Galaxy S5 Exynos (G900H), but it seems that this model was never supported by CM and now by LineageOS.
At first I tried to flash the regular Galaxy S5 (klte) ROM, however the regular system.img and recovery.img didn't work at all on my specific special model (Exynos) obviously, but I had to try.
I saw a few unofficial ROMs for that model over the internet but I need the source code for them (in order to edit it by myslef) and some explanation for how to combine the new Exynos code with the original CM (or LineageOS) repository.
So, is there any way to build a CM ROM for Galaxy S5 Exynos (G900H)?
