After months of endless rumors, the Sony Xperia Z Ultra was announced back in June. Its certainly one of the biggest smartphones that Sony has made, with respect to its sheer size, as it touts a 6.4 inch full HD display. If you don’t like running Sony’s customized Android 4.2 user interface on that gigantic display, there’s now a alternative available which brings an experience that’s much closer to AOSP. CyanogenMod 10.2 nightly builds have started to roll out for the Sony Xperia Z Ultra, not only bringing a refined user interface, but also an updated version of Android.
That’s right, CyanogenMod 10.2 for Sony Xperia Z Ultra brings Android 4.3. Installing the custom ROM shouldn’t be much of a hassle since Sony usually doesn’t lock down its bootloader, if you have a custom recovery installed, you’re good to go. The relevant ROM for Sony Xperia Z Ultra is available under the “togari” codename, it weighs in at 217MB. There’s just one build available as of now, but more stable builds are likely to be released in the near future. Since nightly builds can tend to be buggy, it would be a good idea to create a backup of your data prior to installing the custom ROM. The applicable flashable Google apps pacakage will also be required if access to Google services such as the Play Store is needed after installation. The CyanogenMod 10.2 nightly build for Xperia Z Ultra can be downloaded here.
