Early in the month, Sony officially announced to roll out the Android Lollipop OS update to the company's flagship Xperia Z series smartphones across the world in February.
Sony even confirmed that the new software update will be first released to Xperia Z3 series smartphone and later to the older flagship models.
Xperia Z3 owners, who are eager to explore the newer, visually appealing interface and other numerous customisation options of the Android 5.0.2 Lollipop, can try installing the new CyanogenMod CM12 custom ROM.
We like to remind our readers that this new CM12 series custom ROM is a nightly version. It is unstable and has some un-tested bugs in it.
So, we advise our readers to go through the whole tutorial article before going ahead with the custom ROM installation.
Some of the features that are missing in the CM12 nightly version are:
Theme Engine
Quick Settings reorganisation and customisation
Quick Settings Ribbon mode
Navigation bar reorganisation and customisation
Sound panel customisation
Lock-screen quick unlock
[Note: Cyanogen has confirmed that they are on final stages of the development (85% complete) of the stable firmware and would release it soon. Until then users can upgrade their device with the nightly update.]
Prerequisites (Things to remember before installing the CyanogenMod CM12 Nightly):
Users are advised to update their third party add-ons to ensure compatibility
The CM backupscript.sh in recovery will ignore and remove incompatible applications from your system partition (these are usually non-CM apps that users have opted to install). You must install a compatible app (or app pack) to regain that functionality
You can flash CM12 nightlies directly from CM11 M12 or CM 11 nightlies (no need to wipe), provided you read and followed the above 1 and 2 steps
Once on CM12 nightlies, you cannot downgrade back to CM11 without wiping – if you are thinking of just exploring the release, then take a backup of your existing installation if you want to go back to it.
Users must install Lollipop OS compatible recovery before installing the new CM12 custom ROM.
Make sure the device is rooted before going forward for custom ROM installation
This new CyanogenMod CM12 Android 5.0.2 Lollipop firmware has to be installed on the Sony Xperia Z3 (aka Leo) model; if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number]
Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
Users make sure you have installed USB drivers on the PC, or else your smartphone (Xperia Z3) will not be recognised by the computer.
Make sure your device has more than 80% battery, or else there is a chance of smartphone getting temporarily bricked if the installation process is interrupted mid-way.
[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) Android devices. If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or being permanently irreparable. International Business Times, India Edition cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked. Hence, users are advised to proceed with caution.]
