Step 8 was required (set password for root on the phone) otherwise from the pc I could not login as root. (It did not accept the root password. But when I changed/set the same as was/ the root password on the phone in fingerterm, I was able to login as root from the pc.)

However if the pkcon refresh and version --dup do not require root, then we can skip step 8. As I said this it how have done and how it worked without any problems for me.
