A number of devs are actively working on the Xperia Z2 and it looks like a CyanogenMod 11 port (based on Android 4.4.2) could be heading to the handset soon. Giulio Cervera (aka Kali from the FreeXperia team) teased the following picture. However, don’t expect it in the immediate future as a number of features are not working right now including Wi-Fi, camera, audio and Bluetooth.
In addition, DooMLoRD has released the DooMKernel for the Xperia Z2, which includes a number of tweaks and optimisations. Further information can be found on XDA-developers.
