I'm not sure (wait for a proper answer) but I think ROMs from MIUI 9.5.19.0 and above are ARB4. I recommend that you flash a fastboot ROM that include the proper firmware for Oreo.

I will like to ask people why recovery downgrading is risky as with custom recovery u can have n number of possibilities

Thanks buddy for ur help, I successfully downgraded to 10.2.1.0.
One more question,what is the minimum ROM version that i can downgrade to (I have ARB 4)?

Now your ARB version is 4.
You can download the offical ROM image package and exract it.
Then open the file called "flash_all.bat". Look for "set CURRENT_ANTI_VER" in this file and look at the ARB version of the package.
If the anti level is 4 , it's safe to downgrade to this version.
If it's below 4, DO NOT flash the ROM or your phone will be bricked.
