After many days of searching and tests, here's the Beta build of Marshmallow for Locked and Unlocked bootloaders.
WARNING
This is a beta firmware and it may not work on your device, only way to come back if you are in bootloop will be to flash a stock ftf with flashtool.
INSTRUCTIONS
1) Better to be on latest Lollipop, so here's a ftf and a flashable zip with recovery:
