I really looking forward to Sony XPERIA M5, but it will be available only in selected markets. For now, i download firmware from Emma and upload complete system folder for you. I don't scan it so much (very less time for now), but it is still Android 5.0 Lollipop (i don't understand why, but probably thanks to Mediatek CPU). You can download it below (link is on my site). After firmware will be normally available, we can delete this topic...
