Well, I did it 
I downgraded PR 1.3 to PR 1.0
Generally, I used cert with PR 1.0 version. Then, I flashed PR 1.0:
It failed at cmt-mcusw:
So I flashed CMT from PR 1.3:
Now everything works Check screenshots
So, finally, I can confirm, downgrade is possible
I downgraded PR 1.3 to PR 1.0
Generally, I used cert with PR 1.0 version. Then, I flashed PR 1.0:

I may make a short writeup, but atm i dont have time.
Also, this is really not a beginners task.
There is nothing that will make this an easy task - at least not without someone willing to spend a considerable amount of time programming.
I had sometime ago same results with downgrading as mentioned here. However, Iam not sure on the consequences of the CMT not being downgraded by these steps.

Yes, CMT can't be downgraded. In my case, (on PR 1.0) to make CMT working I needed to flash CMT from PR 1.3, that worked. CMT from 1.0 gave error, the same situation like flashing EU PR 1.3 over CN PR 1.3.
And yes, that's not for beginners. I had time and old N9 in bad state, so I took a chance.

May I ask why, though?
Why would you deliberately NOT want updates to an operating system?
Nostalgia? Or to claim that this is a "collectors item" with "original firmware"?

Thank you a lot!!!
I've spend much time searching this, but haven't found...
You are the saver, man!
Again, thank you a lot, downloading now
I needed it because I want to try downgrade to PR 1.0/1.1. Probably not possible, but why not try
