1. Flash ROM
2. Flash Gapps that you want
3. Flash Kernel (I've never tested RenderBroken's kernel, sorry)
4. Flash any firmware thats cm12s, I'd go with flashing latest CM12s nightly (not 12.1) then wiping and re-do from 1st step. (http://boeffla.df-kunde.de/bacon/modems/) DONT use Oxygen's, it will brick your phone and ofcourse, again not a 12.1 modem.
5. Download this(http://www.mediafire.com/download/94...05Q_Extras.zip) and flash NON-HLOS.bin via adb fastboot
I'm very tired right now so.. if you don't understand how to adb fastboot et.c i'll help you later.. but this is how I did. I didn't download cm12s firmware, only flashed latest cm12s nightly.
