You first need a .ftf firmware file from here

Then follow this guide here - Ignore the title as it's the process you need to follow simply use the firmware from above instead of the Xperia S firmware listed but everything else is the same in regards to Flashtools etc

Hi you can unlock your bootloader and flash custom from Trinity and flash custom kernel from Trinity. Now camera works fine! Sony please pay attantion that problem with camera on Z1/Z2 can be resolved if you change your stock kernel on another stable kernel! http://forum.xda-developers.com/xperia-z1/development/ub-trinity-vengeance-raptorx-v1-0-t2838835
