[Completed] PROBLEM : Upgrading by Flash, Samsung Galaxy S6

Hi. I've just bought a Samsung Galaxy S6 AT&T version (GT-920A) and having trouble to instal OFFICIAL Firmware from Sammobile which upgrades to 6.0.1 Marshmallow.
Is it really possible that we can't install SM-G920F ROMS on the version of my phone ? please, help me. Is someone have an issue for install another Official ROM than the AT&T one ? Please.

Samsung s9+ came with android 9. Is it possible to downgrade to android 8?

Hello everyone, a noob here
I bought Samsung galaxy s9+ however I cannot use the sim+sd hack because of stupid message which pops up.
I read how downgrading to oreo is the solution. My phone came with pie (have not upgraded to android 10). The question is: is it possible to downgrade to oreo if a phone came with the newer software (pie, in this case)?
I had my s5 succesfully downgraded from marshmallow to lolipop however that s5 came with lolipop.
Also, how reliable is this method?:
