What is SMT Download, really?

[LoganDark]

I've seen it all over the Internet, with the warning "DO NOT try to unlock SMT Download mode, or else your IMEI and Widevine certification will get wiped". (I assume the Widevine certification is for DRM in apps like Netflix)

I don't have a OnePlus 7 Pro yet, but it'll arrive in about a week and I'm trying to find out everything I can about the device. Plus if anyone knows anything about this, I'm sure other people are curious about it too and would like to have a search result to click on to find out more.

Is SMT Download mode some sort of super-powerful data-flashing mode used by the factory to configure devices after manufacturing? Is it possible to recover the data wiped when enabling it? What are its capabilities?

It allows you to re-flash all partitions with a qualcomm flash tool. You can start it by turning off your phone, hold the louder button and plug the phone into your pc.

I think you're confusing it with regular download mode.

no, on the phone its both the same. you just change the mode in msm download tool from "upgrade mode" to "smt mode".

This allows you to reflash all partitions, even IMEI

Ohh - so SMT mode is the super-powerful factory flashing mode? Good to know. Is it just a straight "overwrite /dev/sda with this blob" thing?
