Though it seems skeptical if the Sony Xperia Z would receive stock Android 6.0 Marshmallow firmware update, here is a port from the latest AOSP source code, released by Google recently. Following the AOSP port, the official CM 13 ROM has been released for many Android devices like the LG G4, G3, G2, HTC One M8, Nexus series and lot’s more. However, neither stock nor CM 13 is available for the device at the moment. Hence, the Android Open Source Project is the only viable option.
Here is a tested and working tutorial to install the AOSP based Android 6.0 Marshmallow ROM on Sony Xperia Z. The listed ROM is an initial built and consist of some bugs at this moment. However, stability and bug fixes can be expected in the future.
As there is no word from the manufacturer about the official release, the AOSP remains the only option available to get the Marshmallow OS running on your device. The ROM is light weight and very close to the Nexus device firmware.
This is an initial release and users may expect some bugs. Over all the ROM doesn’t have any issues like system crashes or force close. With time, users can expect more builds from the developer.
Also make sure you have the latest TWRP setup on your device as Marshmallow compatible Google Apps needs to be flashed via custom recovery. Also, if you are looking for root, flash the SuperSU package at last.
Lets begin with installing the AOSP ROM on your Xperia Z.
