Could you say when there will be a new working version of this rom?
And which rom you will support and recommend the most (carbon, liquid or pac man)?
I really can't provide any ETA. Keep in mind that I am not part of the ROM developer crew. I just merge our device tree into their source code and compile it. Still using the same CM12.0 device tree provided by u-ra with minor adjustments. I don't have the time or resources to become a new device maintainer. Will update my repo on a regular base and try to provide new versions, but when the ROM developer changes prove as incompatible with CM12 device tree there is not much I can do unfortunately.
The second question is more a matter of your personal preference, all 3 repos are kept up-to-date for now. They all have a compareable set of features. My personal favorite is CarbonRom, I used it for a long time on my old phone (an ancient HTC Desire Bravo - Credits to spezi77 :good it was always giving me the best mix of functionality and features for my own demands.
