Prepare your phone:

  1. This guide is only for an Xperia Z Ultra C6802, C6806 & C6833. If use it with other devices, you could brick them. Check your model number by going to Settings>About Device.
  2. Charge device so it has at least over 60 percent of its battery to prevent you from running out of power before flashing completes.
  3. Back up the following:
    • SMS messages
    • Call logs
    • Contacts
    • Media – copy files manually to a PC/laptop
  4. If your device is rooted, use Titanium Backup.
  5. If you have CWM or TWRP installed, create a Backup Nandroid.
  6. Enable device’s USB debugging mode. First, go to Settings>Developer Options>USB debugging.  If Developer Options is not there, go to About Device and look for your Build Number.  Tap build number seven times and go back to Settings.
  7. Install and setup Sony Flashtool. Open Flashtool>Drivers>Flashtool-drivers.exe.  Install the following drivers:
    • Flashtool
    • Fastboot
    • Xperia Z Ultra
  8. Have an original OEM data cable to connect 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.
