Thank you! I suppose is a hard way... I wanna learn deeper about this!Don't wanna discourage you but I think it's a too long way to go to make a Snapdragon ROM working on Exynos device.
I read guides that say "change some files, edits these other files..." It looks to easy to be true!
Maybe it would be easier to upgrade directly from cm-14.1 to los-15.0 for the same device...
I'll keep reading and learning!
