hmmm I am using 20D and CM11 Snapshot 12 and have no issues, just that after first boot brigthness is very low, but after turning screen off and on again the brightness is working well. I just would use 4.2.2 base to get more recent recoverys. I am just wondering if there is a different between radio versions or so. Was not able to get an overview over all different parts included in different bases....
