The Sony Xperia Z2 and the Z3 smartphones together and finding a brand new over the air software update to the Android 5.0.2 Lollipop. You can read up on everything inside the 23.1.A.0.690 build number from this post. Those of you who have already found the OTA update and updated to the Lollipop might be looking to gain root access. That way you can begin installing root-requiring applications, custom ROMs, custom firmware and even increase the device performance by removing bloatware and more.
Before starting the guide after the jump for the Xperia devices, you should read our list of essentials that you should do before starting.
The first thing you should know is that this guide only works for people with an unlocked bootloader. You cannot flash the files below if your bootloader is locked. There are some rooting guides out there for different firmware versions that will work with a locked bootloader, which would have sounded next to impossible a few years ago. Nonetheless, you must unlock the same before coming here.
- The next thing you want to do is back up the Xperia data using a third-party application from the Google Play Store such as Helium for Android, or any other app. others will prefer using the built-in backup options that comes with the phone. It doesn’t matter how you do it, just take the data away from the internal storage or else it might get wiped if you take a factory reset.
- Moreover, you want to enable the USB Debugging Mode which is done from the Developer Options menu. If you cannot see the Developer Options menu you must unlock the options by tapping the build number seven times.
- You should have the up to date USB Drivers by Sony before starting so that yo are successfully connecting to the computer.
- Only applying the following Xperia guide if you are an advanced Android user. That way you can get out of trouble and avoid bricking your device.
- Rooting with the guide below does void any warranty you might have left on the Z smartphone.
