Unfortunately I can't post on the slim thread but the 9-9-2014 I have flashed on my g900T tonight. I used a version of an inverted velvet gapps for aosp 4.4.4. You can search for darkhorse inverted apps you can use any of the 4.4.2.+ I believe. These Gapps look great with it.
Also the pac-rom is fully functional with the g900t also. I flashed both and have both working.
Both roms camera, dialer incoming answer, APNs [Editable and can be saved but they are already working].
If you aren't interested in the camera for g900t Mokee Rom and Cabon Rom both are ajust about fully functional without the camera. Carbon Rom you need to just add the APN to get data which you can search for instruactions. Its very easy.
And CM11 seems to be fully functional it just doesn't have all the MODs built in that the other AOSP Roms do. Its perfect for anyone that wants to switch for stock to AOSP.
This is true up to todays date to my knowledge. I am just thrilled I finally have a working SlimROM on my S5 as of today.
