Prepare your device:

  1. This guide is only for use the Sony Xperia Z1 C6906, using it with another device could brick it. Go to Settings>About Device to look for and check your model number.

  3. Back up the following:
    • SMS messages

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.
