How to really downgrade Galaxy S6 SM-G920F firmware from 7.0 to 5.0.2/5.1.1/6.0.1? - Galaxy S6 Q&A, Help & Troubleshooting

Hello
I've been reading forums and downloading files for days. Many of the links in the posts no longer work. Posts are 5 years and older. There are no new ones. At least not one that actually works. Downgrade I mean. That's why I wrote this question and I'm asking for help - how to really downgrade my Galaxy S6 G920F.
Thanks for the help.

[Q] root for a Korean Galaxy noste 10.1

Hi there all!
I just got a new galaxy note 10.1 from South Korea and I have some questions.
I tried to find a guide to root the device but I couldn't find anyone specific for this model,
and I'm not sure if it's because I'm new to android (former apple fan, first android based device I own),or just because there aren't any
I hope someone can help me and guide me a little bit
Many thanks

I've got the same model that I bought when I lived in Korea last year. The file I've used to root is called
CF-Auto-Root-p4notewifiany-p4notewifiany-shwm480w.tar.md5
I got it somewhere here on the forum (don't remember where, so search for it. I just install it with Odin (again, read the root section on how to use Odin)
As for other firmware, I haven't had much luck. For some reason, the FW installs, but won't fully boot (boot-loops at Samsung screen). I haven't asked any of the smart people on here for help, but there is probably some trick to it. This model appears identical hardware-wise to the 801x models, but I guess it's not. I ran into the same problems with my original Galaxy S phone when I lived in Korea, only it was much different hardware-wise than the international version.
So rooting is easy, other FW, I haven't had luck with, but I haven't tried that hard to change it, either. There have been a few posts specific to this model on here, so search for them, too. But again, very little info on this model.

[Completed] *HELP* Rooting Samsung Galaxy S5 AT&T 5.0 G900A

Hi, I've been searching the whole the web for rooting a at&t samsung galaxy s5 android version 5.0 for a week now. I haven't found a single way. All methods for rooting any other model works. But none have succeeded with the at&t model. I heard you can downgrade it if you have 5.0 but it can brick your phone. I wanted to try it but I didn't want to take the risk. If anyone knows a way to root the at&t samsung galaxy s5 please help me and others tying to find the answers. Thank You.
