Just received my Z3 Compact after ordering online. It's a great phone, but the File System Version is APAC-LTE_23.0.A.2.93, which is the version designed for the Asia-Pacific market. I want to install the Global or UK version of the software, but I don't want to unlock the Bootloader as I've read it ruins the low-light performance of the camera. Does anyone know how I can install the global version of 4.4.4 instead of the APAC version?!
