I rooted my phone (SM-G955U) a while ago using the PartCyborg method found a while ago, but it's not too useful to me and I'd like to unroot it. However I am plasered with model mismatches and auth errors in odin no matter what firmware I try to flash onto it, and I cannot find any firmware that matches my baseband version G955USQU3CRC7
Am I not doing this right? Thanks in advance for any help.

Had a similar issue yesterday when I tried to update my rooted 5.0.2 to an official 5.1.1. I have used ODIN many times before since SGS3, and back then you were able to mix your system image from other regions, but that apparantly has been locked down by Samsung. Now you can only update an official version of the rom if it exactly matches your existing region. Because you updated your SK international S6 and tried a region set rom from Czech it most likely failed towards the very end of flash with "FAIL".
Your options are: 1) you download the 5.1.1 version for your region in ODIN format from SAMMobile or 2) you use Smart Switch and let it do it for you - in this case you will need to know the SN of your phone as it is used for verification.
Samsung has locked down the serial number with the regions that come with it. So if you have to install, you should update it or use same region odin file. There is a way to break this chain if you are rooted and some additional files are being used in the odin but I am not completely sure as I have not tried it yet. But there are chances that you may void your warranty if you try that or the worse hard brick as it can sometimes change your serial number if not used properly. but I wouldn recommend that. I'll let you know once I understand the usage correctly.
Hi All,
I have a moderate experience in flashing firmwares and modding my samsung devices over the years.
I have recently purchased an S7 which is unfortunately a SM-G930V model, i thought it would have been the SM0G930F which would have made life much easier.
I want to know if it is possible to get the original Australian firmware or even generic stock firmware on this device?
My issue is with the network settings where i have manually put in APN settings my match my carrier and 4G coverage in australia.
If not am i able to just flash a different baseband to this device preferably Australian?
I have read that flashing a different model firmware will soft brick the device, i just want some insight before i start breaking things, also what are my options.
Much appreciated, thanks, Will
You have the snapdragon s7, you can't flash the exynos 930f firmware on it, you can only flash the american firmware. You might have luck with the 930u unbranded firmware just do some research on it.
Thanks mate,
I'm going to flash this firmware using ODIN, do you know if it will be successful?
https://forum.xda-developers.com/att-galaxy-s7/how-to/xda-community-love-g930u-t3415875
not sure how to check my bootloader version etc
No clue, goto the verizon subforum and see if anyone flashed the 930u firmware on their 930v.
Just tried to flash the firmware to my phone and recieved an error, the phone is now stuck at download mode with error:
sw rev check fail : [system] fused 3 > binary 4
this means the bootloader won't accept the firmware?
LOL, guess ill try another firmware.. Any ideas?
I rooted my note 5 (sm-n920w8) and installed sick as hell rom. Apparently, I installed the t-mobile version of the rom (sm-n920t), as this is what the model number of my phone now says.. I am now trying to unroot my phone, but odin fails to flash the stock firmware for model sm-n920w8. I dont want to just flash the t-mobile firmware, as I am worried it will make the phone useless in my area. Any solutions to this problem?
Hi all,
I successfully rooted my S7 from Nougat using the guide below:
https://forum.xda-developers.com/tmobile-s7-edge/how-to/heres-how-rooted-nougat-s7-edge-g935t-t3567502
But performance seems to be suffering since then. I'd like to unroot back to stock, but:
1. Can't find a stock firmware image of G930A to use with Odin
2. The newest version of Samsung Switch no longer has the "Device Initialization" tab as shown in the guide here:
https://www.youtube.com/watch?v=9QhJngOuLQ4
3. I've tried with Samsung Kies as well, which seems to not properly recognize my device serial number.
Has anyone had success in finding an older version of Switch or other methods of unrooting the G930A?
Hi, same problem. Did you ever solve this? Thanks!
You checked both sammobile.com and updato.com?
If so try G930U firmware since it's just the unbranded firmware for US phones, works on all of them.

I did actually solve this a few days ago to unroot my Galaxy S7 G930A.
I used:
Odin V3.12.3 Patched
G930U Firmware (AP, BL, CP, and CSC files) from Updato (https://updato.com/firmware-archive-select-model?record=9CDE46F3EB8211E7A5F9FA163EE8F90B)
After doing this it honestly feels like I have a brand new phone. Huge performance jump compared to the rooted package.
I rooted my phone again, but this time, for the first time ever, it failed. Jesus!
I kept trying to find a firmware for my build + device, but i can't find any that matches both (not sure if the firmware must match build number).
PHONE INFO:
Model Number: SM-G930A
Build: MMB29M.g930AUCSAPK1
I need help really bad. Thanks
Have you seen this yet? The guide to unbricking the phone at least helped me:
https://forum.xda-developers.com/galaxy-s7/how-to/guide-onelatest-stock-fw-csc-root-t3702963
Since you're on a G930A which is snapdragon, you can use any snapdragon firmware that's the same or higher than what you're currently on, which is marshmallow judging by your build.
If you go to sammobile.com or updato.com you should find G930A firmware, you can also try G930U firmware which is the carrier unlocked firmware for snapdragon.
Lastly what root method were you trying? Since you're on Snapdragon, your bootloader is locked, so the methods that work for G930F/Exynos won't work for your device, which might be why it bricked.
