LG G3 D855 Stock Firware on LG G3 D850 - G3 Q&A, Help & Troubleshooting

Hello,
Since we have received android Marshmallow update for LG G3 D855 (international version), I am wondering if anyone has tried to install D855 stock firmware file (android 6.0) on D850 (AT&T) version and had any success? I am hoping D855 and D850 are not too different because both use same processor.
I am asking this because I used to have a SONY phone from AT&T and I flashed international version firmware on it and it worked perfectly fine. This was about two years ago.

It will brick the device they are not as similar as you think. Only flash D850 firmware on the D850 phone.

Supposedly, the D855 firmware can be modified/patched to run on D850. At least, there is a Lollipop D855 ROM that runs of D850. So in theory, maybe the D855 ROM can be modified to run on D850.

Thank you. That's what I was thinking. LG G3 is my daily use phone so I can't take a risk. That's why I was wondering if someone has tried it. I know folks at XDA are talented and someone probably have found a solution.

Is there any known good method for rooting an LG G3 F400K running 6.0 ?
Reason I ask is that I have tried a few, none seem to work? Updates to most of them were around 2 years ago?
If you are on v30n firmware is impossible to root, for moment, and you need to revert to an older version on firmware , if lg flash tool don't work, give a try to lg up
