The FreeXperia custom ROM community took good care of you and here I am to guide you on how to install Android M on Sony Xperia Z Ultra by using FreeXperia ROM.
Here I am to tell you from the start the fact that this tutorial is only to install the Android M Developer Preview ROM build provided by FreeXperia for Sony Xperia Z Ultra, so don’t even think of trying it on any other device. You should also be aware of the fact that there are some bugs that might annoy you, while the final build will be much more stable and may come with even more features. And just as it always happens, you should know the fact that this operation is not official, so it will make you lose the warranty of your handset (use this guide on How to restore it). However, this also means that if something wrong happens, you will be by yourselves, so make no mistake.
Before starting, you must make a backup of all the important data, additional files, apps and settings as this procedure will wipe all the data. Make sure that the device is rooted, with the latest TWRP already installed and that the bootloader is unlocked. Even more, your Sony Xperia Z Ultra must have at least 60 percent of battery charge in order to avoid the unpleasant surprise of seeing it powering off during the installation process.
Make sure the USB drivers of this handset have been installed on the PC and also prepare the original USB cord to establish the connection. Are you ready for the procedure? Let’s begin:
