How to find build number on a (soft)bricked phone? - Android Q&A, Help & Troubleshooting

I have a Samsung Galaxy S6, model number SM-920F, provider T-mobile Netherlands,.
My phone is stuck in a bootloop but TWRP is still accessable, and I want to know the build number so I can download the right firmware and use Odin to put back to stock firmware.

First of all, I assume that you're using TWRP 3.0 or above
Boot into TWRP, go to Mount, check System, go back to TWRP's main menu, go to Advanced > Terminal and type this line in it:
Code:
cat /system/build.prop
And press Enter when you typed that line in Terminal
(Scroll around, and you'll see some lines
starting with G920F (Copy one of these, because that's your build number)

That method only works on Samsung phones on stock ROMs or on non-stock ROMs with stock build fingerprint (aka ro.build.fingerprint property in build.prop)

So how can I find my build number? Please.
PS: when I do the manipulation, I can see:
