How to get official firmware back on Samsung Galaxy J7 (2016) J710FN ?

I rooted my phone a a few days ago and now I'm trying to get back the official firmware which should be possible.
I flashed TWRP, SuperSU and "no-verity something".
Yesterday I tried to unroot my phone and I saw in a tutorial I only have to press the fully unroot button in SuperSU and it should work.
Well it did, but I still couldn't open Snapchat I thought it was TWRP. I saw that I need root access to uninstall TWRP. I tried to flash SuperSU once again and then my phone just gave up.
It didn't break or something, but when I boot my phone normally it I get an error message, I have a german phone... I can't translate it perfectly, but it says some "integrity check" has failed and I have to factory reset my phone. That's where the problems started.
When I press the "reset" button, it tries to factory reset my phone, but I think it can't read internal memory. When I connect it to my PC it only shows my SD card.
When I go to wipe on TWRP it shows "internal memory 0MB" and I think it has some difficulties reading the internal memory.
My question is, is there a possibility to get the J710FN firmware and all the things back, like the original recovery and all the things.
I tried to flash the original global firmware via ODIN3 v3.12.3 but it fails. My phone says "SW REV CHECK FAIL Device: 4 Binary: 3"
I just want to get back the original firmware without any rooted things so my phone works again.
Oh and I tried to factory reset it in case somebody thinks that's the problem.
Factory resetting doesn't work, because I THINK my phone can't read the internal memory.
I really hope someone can help me.
You can ask me any kind questions for information you need to gather to help me.
Thank you in advance!
I think sw rev check fail (software reverse)mean's that you are trying to flash an out dated firmware (in comparison to the firmware that your phone has on it now)Your phone will block you trying to downgrade your firmware.
Before you do anything you could try the emergency software update and Initialisation in smart switch,I think you need is your phone's serial number(if you still have the box i will be on there)
If all else fail's you could try downloading the most up to date software from sammobile and flash it with the most up to date version of odin you can find

SM-G920F Logo loop ,can acces only recovery and download mode.

Hello everyone , first of all sorry for my bad english , i am not a native speaker
Device: SM-G920F
ROM name: G920FXXU6ERC1 - GALAXY S6 SM-G920F ROM ROMANIA ANDROID 7.0
ROM version and base: don't know
Build number: don't know (look story below)
What I did:My girlfriend had a S6 ,and for the last months he starts acting wierd like freezing mostly random but often when it's charging , sometimes get an icon with an empty battery and an exclamation point ,aflter a while he shut off and starts a bootloop with no acces to recovery mode only download mode,so after a month or so she decided to give it to me to try do something (meanwhile she replace-it with another phone).
First i am not an expert by any means but i love technology and love to learn something new so i try to charge-it to see if he can hold charge and the battery was complet dead but start to charge and even after 2 days of trying to enter recovery mode or something with couple hours of freezing on samsung logo he died from battery so i thinked that it was a software problem not a hardware and start reading about flash and rom's , i didn't have any build number or anything , just the model ,and i downloaded the last rom from sammobile acording to my country ,flashed succesfuly ,installed updates afler the odin flashed but stil on boot loop , but now i can acces recovery mode , so i factory reseted with no luck , so i start read about Nand erase all and i decided to try-it ,i find the pit file on the forum wich was SM-G920F OXX multi CSC ( BGL CYO RTL MET MSR ORX ROM SEB SEE SIO TEB TOP TPH TSR TWO XEH XEO ) but i think that is a bit old ,only say's for android 4 5 6 ,because after that he start freezing , i start flash-it again just with the rom not with pit , and when it says installing updates not even loading something and appears "No command" or "Erasing" on a blue screen.
Please , i wan't an advice , what is the best thing to do next , is that the correct pit file ?where i can find the ones for version 7.0 of android ,is there a way to fix-it?I can provide photos or videos any info.
Thanks in regards.
----------------------------
LE: I resolve the issue by finding the corect rom and pit using the builnumber from the phone case , the secret is to wait after the rom flash ,even the phone seems to be stuck at samsung logo ,just wait at least 10 minutes before do something
