Sheesh ! What do you want ? Blood ?

LOL ! no, it doesn't make any predictions about the elementary particle masses. It's not, and doesn't claim to be, a theory of everything. It's purely a way of quantizing the gravitational field at this stage. I think there has been some preliminary thought on how to put "matter" into the theory, but I haven't got to that bit yet. After I get to the end of describing the formalism, I'll summarise what I understand to be the main results so far.

And no, not a fractional dimension theory.

I will be interested to see if you can recover GR at the end as a classical limit. ;)

Good point. Me too !

I haven't read those bits in detail yet, but I think the way it's approached is to try to construct, in the LQG formalism, a coherent state and extract the classical picture from that. I'm not sure if that work has been completed yet though...
