[HELP] Phone bricked after rooting - Samsung Galaxy S7 Questions and Answers

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:

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.

SM-G930V purchased in Australia

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?

United Wireless S7 stock firmware

Hello everyone. I have had a problem quite some time now. I was attempting to root my Galaxy S7 from United Wireless (which is a regional provider) and I ran into an issue in which a firmware file I was attempting to flash over (with Odin) apparently was incomplete or Corrupted. Now I have rooted nearly every device I've ever owned (omitting the Note 8 I currently use for fear of ruining this one too). I have never however run into a problem with incorrect firmware or incomplete firmware. So I went to go look for the stock firmware for the device, and to my dismay, I find that United Wireless uses a firmware that is either; custom to them, difficult to find, or is not a firmware created by Samsung themselves. To this day, about 1 year after bricking, I have yet to find a way to get the S7 working again. Does anyone know of a universal Firmware or something that can be flashed to get it working again? Maybe even enough to get a custom rom on it??
- Thanks in advance,
Evanzire
Assuming you're in the US, you can flash the SM-G930U firmware, as it's the unbranded firmware for US devices and should flash on any US model S7.
If you boot into download mode (Home + Power + Vol Down) what model does your device show as?
US model S7's use snapdragon SoC's with a locked bootloader, so the only working root method is to use an unstable leaked engineering bootloader that allows (some) boot modifications. Custom ROM's are impossible, and root uses non-standard methods.

Can't unroot Snapdragon AT&T S8+

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.

Finding the correct firmware to fix soft-bricked phone.

Hello,
I'm trying to fix my soft bricked phone with this error (no quotes):
"dm-verity verifiation failed..."
I've already soft and factory reset the phone to no avail, as it still will not boot past the Samsung logo. Googling the problem has told me that flashing the original firmware with Odin should fix it, but after hours of searching I still cannot determine what firmware I need to download and use. Reading some of the threads here supposedly i can use firmware that shares my carrier and country but I cannot find the correct combination on any site.
Country: US
Phone: S7 (G930F) - On the recovery mode screen the full designation is G930FXXU1BPH6
Carrier: T-Mobile
Version 6.0.1
Does anyone know exactly where I can find useable firmware for the phone? Everything I see online (like sammobile for example) just has the firmwares for other countries.
Before the bootlock my phone was rooted if it matters.

The G930F is a primarily European device, so a different region than the US.
The firmware version you have provided is an old version of Marshmallow on T Mobile Poland. The fact that it's Poland doesn't really matter it's still EU region.
Now heres the important part....T Mobile in Europe do not use all of the same bands as T Mobile US so although you can flash any firmware for Europe your phone will not work 100% in the US
So first of all flash with either a nougat firmware for United Kingdom T Mobile or Untied Kingdom nougat undranded (BTU). From Sammobile.
I don't advise going straight to Oreo because there may be a fix for older nougat firmware from EU region to work perfectly in US. Once you upgrade firmware you cannot downgrade.
Once your phone is up and running you just need to look on the forum of how to get a G930F device working perfect on US networks.

I need help to identify the correct firmware for my S7 (SM-G930F)

I bought a new S7 (G930F) at ebay. When it arrived i wanted to update to the newest firmware, but i got an error notification.
I contacted Samsung and they told me to send it in.
They checked it and told me, that they are not willing to help because the phone is flashed with a wrong firmware. I bought it as a new device. This is unpleasant.
The seller doesn't answer my messages, so i thought maybe i can flash a new firmware by myself. The actual firmware is working but it is outdated. (1. August 2018)
But how can i find out which firmware is correct for this phone? How to say if it is exynos or snapdragon?
The phone information
Modellnummer: SM-930F
Seriennummer: 5AF94C0C
Buildnummer: R16NW.G930FFXXU7CRH2
Kernel: 3.18.71-14274519 [email protected] #1
Basisband: G930FFXXU7CRH2
Android 8.0.0
Samsung Experience: 9.0
I would like to flash the latest firmware and i want to use the phone in germany. Can somebody identify the correct firmware?
Thanks a lot
What does the phone say in download mode? The ROM can be modified to lie about the model and firmware, but download mode will tell you the truth.
If download mode says it's a G930F then it's Exynos, if it says G930U/V/T/A then it's Snapdragon.
If it is a G930F then good news is you can just flash whatever G930F firmware you want over top what's on it. If it's Snapdragon then you're a bit stuffed, you can't flash Exynos firmware onto Snapdragon.
For updating it if it is G930F my recommendation would be to find out the region code for your device, e.g. from here https://updato.com/firmware-archive...act=1&r=DBT,XEG,DCO,DDE,VIA,DTM,VD2&v=&rpp=15 then download the firmware using that region code with SamFirm tool https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
Download Mode says SM-G930V
I'm doomed
Yep that's a common scam. If you can't return to seller the next best thing would be to flash the G930U firmware, which is the generic unlocked firmware for Snapdragon.
It won't give you the equivalent experience, but it will remove any bloat and give you a carrier unlocked phone experience.
You can use the same methods I mentioned to get your hands on the latest G930U firmware and update the device, but you may need this specific Odin version to flash G930U over G930V https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
Thanks. Does TMK, TFN, TMB,... make a difference when the phone is used in germany?
Should i flash all 5 files:?:
AP
BL
CP
CSC
Home
I tried and my result is: Flashing only AP was not enough. Flashing all 5 worked fine for me. I chose TMK and even LTE is working. Thanks a lot.
Glad its working, for reference CSC and Home_CSC are both CSC files and you usually pick just one. Home_CSC doesn't do a data wipe, CSC does.
But when changing from G930V to G930U it's always safest to do the CSC wipe.
