Guys, I started the porting work ... It will be finished soon. Please, tell the guys here since I don't have rights to post in that section...
Just bought an n910C (exynos version) for this reason :) but my sailfish efforts will begin in a few weeks. Come join us at #sailfishos-porters at Freenode :)
If anyone has any hints on how to get root running in 4.4.4 I'd love to know. I've installed many different versions to no avail.
Same situation here - tried with various versions of SuperSU flashed through TWRP - only adb root works ...
