How to Unroot the Sony Xperia Z3

Maybe you’ve had enough fun with your rooted Sony Xperia Z3? Maybe you want to go back to stock? Either way, this guide should help you unroot your device and get it back to stock. It’ll also install all of the system apps and reset everything to factory settings. Here’s how to unroot your device:

Unrooting is the process of removing root access, a custom recovery (if you have one), and just trying to get the device back to as close to stock as possible.

Some of the reasons for unrooting your Sony Xperia Z3 are:

  • Sending in the device for warranty (most, but not all unrooting procedures reinstate the manufacturer warranty if you had one before rooting).
  • Starting over (simply undoing everything you did while rooted so you can have a clean slate to start over).
  • Fix any issues (Maybe rooting messed something up? No problem, unrooting will take care of it for you).
