Prepare your phone:

  1. Only use this guide with the Sony Xperia Z3 Compact D5803. If you use this with another device, you could brick it.  Make sure you have the right device by going to Settings>About Device, and looking for your model number there.
  2. Charge device so its battery is at least over 60 percent. This is to make sure you don’t run out of power before the flashing process completes.
  3. Back up the following:
    • Contacts
    • SMS messages
    • Call logs
    • Media – copy files manually to a PC/laptop
  4. If your device has root access, use Titanium Backup for system data, apps and important content.
  5. If you have custom recovery such as CWM or TWRP installed, make a Backup Nandroid.
  6. Enable device’s USB debugging mode. Go to Settings>Developer Options>USB debugging.  If Developer Options is not in settings, go to About Device and look for your Build Number.  Tap build number seven times and then go back to Settings.  Developer options should now be activated.
  7. Install and setup Sony Flashtool. Open Flashtool>Drivers>Flashtool-drivers.exe.  Install the following drivers:
    • Flashtool
    • Fastboot
    • Xperia Z3 Compact
  8. Have your original OEM data cable on hand to make the connection between your device and a PC or laptop.

Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device.  Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers.  Be responsible and keep these in mind before you decide to proceed on your own responsibility.  In case a mishap occurs, we or the device manufacturers should never be held responsible.
