Finally I solved my problem very simple way - replace my region 41 with the same region dump from other unit. Now I have clone unit with LMT subscription. Funny, isn't.
Now I have unit with duplicated UnitID. This is no problem for me, but I was curious is it possible easy way to change UnitID. I discovered that it's possible. Even in a different ways. But at the moment I don't know how to retain HWID after this change.
