Sony’s Xperia Z2 isn’t the only device that got updated to Android 5.0.2 Lollipop (23.1.A.0.740). The update is being pushed out on Xperia Z3 as well and if you want something more than just an update, you’re at the right place. We have created a guide on how to root Xperia Z3 running Android 5.0.2 Lollipop (23.1.A.0.740). The same guide is available for Xperia Z2 here. However, if you are willing to simply update your phone to the latest build, follow this guide.

  • Make sure your battery is charged to at least 70 percent.
  • The ADB drivers must be set up. Here’s how to.
  • Turn on the USB debugging by going to Settings > About Phone > Tapping the ‘Build number’ at least 7-8 times and going back into settings and then going to Developer Options.
  • Backup your apps and important messages.
  • Download and install flashtool from here.
  • (optional) If you are running firmwares newer than the ones released in October, you’re going to need to downgrade. If not, then root the firmware using this and install the recovery from here. Do keep in mind that you’ll need the installer version.
  • (optional) In case you need to downgrade, you can do so by downloading the FTF file of an older firmware and flashing it. Download here.
  • You can create a pre-rooted flashable zip using this guide.
