Sony Xperia Z

Sony Xperia Z users can now update their phone to Android 7.1.1 Nougat, thanks to the release of CyanogenMod 14.1 ROM by the industrious Android custom ROM developers. With Sony unlikely to release any further software updates for the ageing smartphone, the arrival of Android 7.1.1 CM14.1 ROM gains precedence for the Xperia Z.

As the ROM is not an official release by Sony, you will need a custom recovery tool like ClockworkMod (CWM) or Team Win Recovery Project (TWRP) to flash the ROM and Google Apps zip files on the Xperia Z.

IBTimes SG reminds readers that it will not be held liable for any damage to your device during or after the Android 7.1.1 CM 14.1 ROM installation. Users are advised to proceed at their own risk.
