Can't flash stock firmware - Samsung Galaxy S7 Questions and Answers

Hi! A while ago I decided to flash TWRP and a custom rom (LineageOS) onto my S7. After a while I decided that I would prefer the stock OS. So I tried flashing the stock ROM with Odin and a zip file downloaded from SamMobile. But it would always fail when it got up to flashing system.img. So I tried another firmware using SamFirm, the same problem persisted. So I tried flashing the stock ROM using FlashFire, but no partitions showed up. Smart Switch and Kies 3 just said that my device is not compatible. If anyone can help me, it would be massively appreciated.
P.S. I am doing everything right, I've done this exact process on many other Samsung phones.

Are you extracting the AP, BL, CP and CSC files from the zip, or just putting the zip straight into Odin?

"debranding" the g920f with odin dont work

hello guys,
yesterday i bought a galaxy s6 (g920f). it got the 1&1 branding but its simlock free. i just read about, that i can use this fw G920FXXU1AOE3_G920FDBT1AODQ_G920FXXU1AOE3_HOME.tar (5.02), flash it with odin, after that a wipe and than update to 5.1.1 with smartswitch. than i got a complete debranded dbt firmware.
ok, thought it would be easy ;P - a ran in conflicts now. odin got errors on flashing. every time it failed flashing. i read about the "hidden.img". i should extract the firmwarefile with 7zip, delete the hidden.img and after that i have to make a new .tar (not tar.md5, cause i will get md5 errors in odin, already tested ) - still fail on flashing....
than i found a pit file, but i dont know how to handle that. i never done that and dont know, whats happening when im flashing it and i dont even know which i have to download.
here is the link http://forum.xda-developers.com/galaxy-s6/general/g920f-pit-file-banded-firmwares-t3118459
hope someone can help me.
best regards taker-`
//edit: meanwhile i triggert knox, so i tried to flash twpr and try to flash the dbt 5.1.1 firmware with the recovery....recoveryflashing also failed - why?
Are you using the official Samsung cable? Odin is very picky about usb cables. How many times did you try? I recently unrooted using Odin, and the first time it failed as well for no reason. I just reconnected the usb cable and tried again, then it worked.
i used the original cable, but i also tried a original cable from a galaxy s5 and s4. same error all the time.
i flashed my s5 with the same cable, same odin version...i want it on stock firmware, cause i sold it. that worked well, but with the s6, it dont work.
Flash this stock 5.1.1 ROM via odin to debrand your G920F.

Lost IMEI and baseband, ODIN keeps failing

Hello, I'm getting crazy and I don't know what to do anymore.
I have been using the Oreo Rom in the last few days and I wanted to go back to stock firmware using Odin.
I downloaded the last firmware available for my country (ITV) and installed Odin.
The app kept failing when trying to flash and I wasn't able to install the firmware. I tried by flashing only the AP file and I was able to delete TWRP and install the stock recovery. The phone booted up but it acted strange (the touch screen was unresponsive). So I tried to align the CSC using Odin but it kept failing when trying to flash the BL.
I then flashed all files (AP, CP and CSC) without the bootloader and now I have no signal.
Please help me! How do I restore my baseband?
You cannot flash an older baseband through Odin than the one you're on at the moment, at least that's what I was fighting with a few days ago. Check that you're really flashing the latest stock FW and that its baseband is the same as the last one that worked or newer.

SM-G930F SW REV Check fail device 2 binary 1

Hey guys! I have a problem. I have flashed on my Galaxy S7 (Exynos version) the galaxy Note Fan Edition Port rom a couple of weeks ago, but now I flashed the latest stock firmware from Sammobile via odin and it always fails at the bootloader. I don't know why? I searched for many hours for a solution, but nothing works.... I hope somebody could help me
Here is the link for the note fan edition rom: https://forum.xda-developers.com/s7...-galaxy-note-fan-edition-port-vol1-0-t3633626
OEM unlock on?
Could also be that the latest bootloader prevents rolling back, so if you're trying to go from a newer bootloader to an older one it won't let you. You can probably just exclude the BL file and be fine.
Is that Fan Edition ROM you flashed not a S7 Edge rom made to work on the S7..! Maybe your phone shows up as a G935 now?

Hi! Same error but different situation.
I was on the latest firmware 8.0 ITV, I wanted to downgrade to nougat, so I downloaded the first 7.0 firmware BTU (the one that was the best for my S7).
I opened all the firmware files on odin 3.13.1 and I started the procedure but at a certain point everything stopped, on odin the message "failed" appeared and on the phone the message "sw rev check fail (bootloader) device 2 binary 1".
I tried with a different version of odin but the message remains the same, I also tried without flashing the BL file but nothing ... In the end I had to flash again the latest firmware oreo ITV and no errors appeared, but I find myself at the starting point
specific that my S7 has never had modding operations, the knox counter is perfectly at 0x0, I have always used only original firmware and never had problems with odin.
How can I downgrade without having in that error?
Hi just flash this version of latest nougat G930FXXS2DRDI, this is binary 2 firmware (XEO)

Cannot flash proper Stock ROM on s8+

Hey Guys,
So in early January when the s8+ Oreo update got leaked I followed the guide to install it on my device. However, I noticed when I go to download mode it shows up as the SM-G955U and my device is SM-G955W. When I tried download the stock firmware and flashing it in firmware it fails in ODIN. So my question is how would I revert back to the stock firmware and ROM that came with my device, I've tried many different zip files for the stock ROM thinking it might have been corrupt but it does not work.
Edit: here's the tutorial I followed to flash Oreo on my device initially

Thanks!
Try the patched version of Odin 3.13.1:
https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
I did the same thing and used this to get it back to SM-G955W. This version has support for .lz4 files, which is used in the Oreo ROMS.

How would i go about installing stock rom on S7 Edge using TWRP with SAMOBILE files?

Hi, as the title says im looking for a way to keep TWRP while i install the newest stock room for my specific version of the S7 Edge.
I already downloaded the 2GB zip file from sammobile, but that files are made for the Odin installer, and if i install it trough Odin i am guessing TWRP will go away.
tl;dr: Im looking for a way to have MAGISK hence TWRP and newest stock for my specific version of the S7 Edge

The only way you're going to flash any kind of stock firmware while keeping TWRP is if someone has conveeted your stock firmware into a flashable.zip that can be flashed in TWRP. If there is not a flashable .zip available, you wont be able to do what you're trying to do.
The only other way to flash stock firmware is to use Odin or mobile Odin and they will both remove root and TWRP.
Typically, Samsung devices that are rooted and have TWRP can only update the stock firmware via Odin, mobile Odin, Kies or SmartSwitch. This removes root and TWRP which means those users have to root their device again and flash TWRP again.
