The instructions below can be used to flash ANY firmware build for 2017 Sony Xperia devices and beyond. While Flashtool was recently updated to support some of the key 2017 Xperia models, including the Xperia XZ Premium and XZ1, we thought it would be useful to write a tutorial for Newsflasher as it provides an alternative, easy-to-use way to flash your Xperia firmware.

This is where Newflasher, a command line Xperia flashing tool developed by XDA member munjeni, comes in.

Using the Flashtool application has been the main way to go about this, but when Sony released its 2017 Xperia models, it changed the flashing process which rendered Flashtool redundant. Whether that relates to upgrading/downgrading major Android versions, debranding the handset or simply changing the firmware region for faster updates. One of the most frequent questions we get asked from Sony Xperia owners is how to change the firmware.
