right ORDER installing EU ROM on Mi8 UD OR pro. Originally on CHINA ROM

[miginis]

I have unlocked my Mi8 UD around 5 days ago. Could not find the right ROM, hence loaded my the Mi8, all data gone, no problem. Works fine.
I check the Developer options says Mi Unlock status is Unlocked.

1.Does that mean according to this guide: Method 2: Fastboot Update from http://en.miui.com/a-234.html I can proceed to Step 3?
2. or should I run the Step1 again and while the phone is still in fastboot mode I should quickly switch the MiFlash tool and load the Mi8 Pro ROM?

3.If I can directly go to step 3, which setting in the Developer Options on the Mi8 phone I have to switch on? OEM Unlocking, USB debugging? Anything else?
Should I flash the phone with SIM or without?

Thanks for the help!

Unlock BL / done
Next --> Fastboot Flash recovery
Then reboot recovery, format data, upload Rom, flash Rom, easy as pie, start reading, it helps to gain knowledge...
