Where can I download the official MIUI ROM (a pre-treble version)

[rrrsssttt]

So I made the mistake about trying to install Lineage OS, without updating MIUI.

So my plan is to reinstall an earlier version of MIUI for the note 5, upgrade that to its current iteration. And then proceed to install Lineage OS.

I just need help finding a version of MIUI. If someone can help me I'd appreciate it.

Or if my plan is dumb, I'd appreciate that feedback as well
