No I haven't.. and I can't... my Sony devices (but I think that this is
a practice of all OEMs/ODMs) are using a Sony signed venus firmware, so
I am totally limited to use the firmware that comes with the device.

Besides that, the version is still different so, even if I had any
possibility to try that, I don't think that it would work anyway...
