Don't use kingroot/kingoroot. They do get the job done but they install viruses on your phone with root privileges. Also, why would you recommend a root app, his kernel date is too new, they patched that a while ago, another reason not to trust a lot of people on the internet without doing research.
Can some help me root this phone?
It seems to stop but it is very busy. If you wait 10-15minutes yo see it jumps suddenly to 83% then finishes much quicker. Try again if you didn't already solve

.. well, for downgrade you should use this official tool http://www.hihonor.com/uk/support/details/index.html?DOC_ID=84943, and you will have 5.1.1 .. but, this yours marshmallow build number is not latest, maybe you should try 860 first .. install firmware finder by Team MT from playstore .. for now I only have problem with sd card unexpectedly removed, still I'm not sure this is software related
i confused what i should i use first? firmware finder by Team MT from playstore OR the tool from hihonor ?

.. as I said, if you want to go back, to 5.1.1 use the hihonor official tool with description in it, but if you want to upgrade marshmallow again from 820 to 860 try firmware finder ..
