The CyanogenMod team have this week released CyanogenMod 11 builds for the Sony Xperia Z1 and Xperia Z Ultra Google Play Editions. Based on Android 4.4 KitKat, the ROMs include everything you’d expect from Google latest operating system, coupled with all the tweaks and add-ons that come with CyanogenMod.

This is the first time CyanogenMod has supported the Xperia Z Ultra, so the current release is an “experimental” one. That means it’s nowhere near stable yet, and is likely to contain bugs and other issues that could cause instability or prevent some features from working.

If you use your Xperia Z Ultra as your daily driver, then, it’s probably best to steer clear from the CyanogenMod ROM for now. Of course, as the weeks go by, it’s only going to get better as the team irons out the kinks and fixes the problems.

As for the Xperia Z1, its latest CM11 release is a another “nightly” build. This means it’s mostly functional, but again, there could be some bugs here and there. It’s best to do your research before you install it to see if there are any known issues that may break features you rely on.

The builds are labeled “honami” (Xperia Z1) and “togari_gpe” (Xperia Z Ultra) on the CyanogenMod downloads page. Like any custom ROM, you’ll need to download the ZIP file, transfer it to your device, then flash it using a custom recovery like TWRP. Don’t forget that you’ll also need to flash the CM11 “Gapps” file to install Google apps.
