Once the Xperia Z Ultra got Google’s blessings to become a Google Play edition (GPe) device, it was only a matter of time before someone would port over the stock Android ROM from the device to those running on Sony’s customized version of Android. However, instead of a port for the standard variant of the Xperia Z Ultra as one would expect, the first port is actually for Sony’s flagship phone, the Xperia Z1, by well-known Sony hacker DoomLord.
Since the hardware is essentially the same in both devices barring the screen, the port didn’t take long in development, and Xperia Z1 owners can start enjoying the Android experience that Google wants everyone to have. At this point, the Wi-Fi and camera aren’t working too well, but work on fixing them is already underway, though since the Z1 sports a unique camera not found on any other Sony device, it might be a while before full camera functionality can be achieved on the GPe ROM.
To install the ROM, users will need to unlock the bootloader on their Xperia Z1, put on a custom recovery and then carry on from there, with full instructions available at the source link. As always, flashing ROMs, especially those that are ported from another device, can be a dangerous process, so be sure to take the necessary precaution before proceeding with anything (take backups, pray everything goes well, and son on.)
