Flashtool developer Androxyde has pushed a latest version of the popular Sony Xperia utility moving it to build number 0.9.19.0. The latest release now supports the latest Sony Xperia devices such as the Xperia Z3+, Z4 Tablet and for the first time MediaTek-based devices are also supported such as the Xperia E4 and E4g series.
We would advise some caution before updating however. Flashtool now needs a template script for your particular handset before a FTF firmware file can be flashed. This can be generated by a program such as Simple USB Logger, but the procedure to capture this data is complex.
This particular Flashtool release only supports the following models: Xperia Z1, Z2, Z3, Z3+, Z4 Tablet, E4, E4g and M4. Androxyde will add a tutorial shortly on how to generate and add new FSC to increase compatibility. In the meantime, if you have a different device, stick to the older build (0.9.18.6).
