Update Sony Xperia Z to Android 5.0 Lollipop With AOSP Based ROM

It has been sweet of Sony to promise Android 5.0 update for the Xperia Z even when the device is now older than the 18 months update policy. However, Android 5.0 update from Sony is going to take time, our guess would be end Q1 2015. So are we not going to use Android 5.0 Lollipop on Xperia Z until then? Hell no!

Thanks to thomas1991_12 over at XDA, we already have a working Android 5.0 Lollipop ROM for the Xperia Z. The ROM is based on AOSP source code for Android 5.0 that Google released a couple of days back.

Xperia Z Lollipop ROM is currently in experimental stage so expect some bugs if you’re planning on installing the ROM. The developer has stated that Camera and Call functionality aren’t working at this moment. So we wouldn’t recommend to install it if you use your Xperia Z as a daily driver.

NOT WORKING (as of November 6, 2014):

  • Camera
  • RIL (Calls + data)

Android 5.0 Lollipop update brings a major user interface overhaul to Android, and it has been named Material Design. You’ll also see beautiful and smooth animations throughout the system along with a ton of new features like Guest User Mode, Screen pinning and many more cool features.

So without further ado let’s hit the downloads section and installation instructions for the Android 5.0 ROM for your Xperia Z.

    fastboot flash boot boot.img
    fastboot flash system system.img
    fastboot flash userdata userdata.img
  9. Once you’ve successfully flashed boot.img and system.img and also wiped the userdata. Then reboot your Xperia Z using the following command:
