ok, guys, I can boot it.
Firstly I flash via rsd last 4.1.2 for uk. It flashed wit no error. Just delete cdt line in the xml file.
Then I flash 4.1.2 for KDDI except system partition and cdt line in xml file
Then I get root via chinese vtool and install BMM.
Now I can boot it only from BPool. And I have Recipe failed Error.
P.S. I have one question:
Why, when I flash xt912 rom into my phone, its lagging and looks like it's too slow, but I have cellular data.
But when I flash xt910 rom, I had no cellular data, but it works flawlessly: no lag, no freezes.
P.P.S Sorry for my english.
