There are enough instructions on the internet. You have to format the data partition. Then connect the mix 2s to the pc and copy the downloaded .zip on the phone and install.

I do not understand the problem that there is no Xiaomi.eu Rom. The Multirom went. And the Dev and the China Rom are also running.
