Hello,
I have checked several threads and didnt find anything specific, so i am going to try and explain myself. I have a SM-G920I phone (galaxy s6), bought in America. I am living in Europe and I have unlocked the network with a code gotten from Samsung. The network and band works great and there is nothing wrong with it even tho the European g920f firmware and g920i have slightly different band/modem.
My friend has a g920f and I have checked in depth her phone and it is exactly the same as mine in everything.
So yes, I want to flash a g920f firmware on my g920i firmware. Please, don't mind why I do it, it is not relevant to my experiment.
I have flashed a modified kernel to my s6 (Droid 5.1.1) in order to root it and back my efs up. Once that is done, I know that if I brick my phone, I can bring it back as long as I have the efs. So okay, I flashed a g920f firmware (Mm) and it failed. I did some research and i guess that there is a file in the md5 which recognizes that my phone is not a g920f and rejects the updating. I have read about pit files and I have seen that all of them set different partition sizes, so I guess that may be another reason why I can't flash the 920f firmware -some file is larger than the current g920i partition-
My question is, if the g920f and g920i phone are TOTALLY equal in hardware, why does it fail? Please, don't give me a silly reason. I am expecting a technical reason.
Also, if I flash on my 920i a pit file according to the g920f firmware, will I be able to flash the F firmware later? If not, why?
Don't worry about band or modem. I will be happy if it gets flashed without any network. It is an experimental thing (i can always go back and flash a g920i firmware)
Thank you!

I asked the other day about using the G920I modem on my G920F as to improve the poor reception on my phone. The next question I hope anyone can answer is would just converting the whole phone to a G920I using stock rom. The hardware in each phone is exactly the same especially the modem which is a samsung shannon. The only difference is the couple of different basebands but these are present in both varients of the modem just software locked. I cant see any reason as to why I could not do this but would like to hear if you have a take on this. Thanks. I have found threads with other people that seem to have managed it but everytime I flash the stock G920I rom it fails. Just wondering what Im missing.

G920I Firmwares SUCKS, i am stuck in 5.1.1 and its a horrible experience, i miss 5.0.2 :crying:
Im on G920F 5.1.1 custom rom and its excellent. I need the modem from the G920i as it addressed the poor reception issue. No such modem has been released yet for the G920F hence I want to change. Once on G920I i will install a custom rom anyway so all will be good.

Have you tried to flash the 920I modem? I think it may be possible to do so as they have the same baseband chip.
But I am not sure whether we can get back the original modem if the flashing failed. I used to have a Nexus 4. Even when I flashed a wrong radio, I can always get back by flashing the right one. It is just a partition with constant data on the device. But I don't know whether samsung is the same.
Flashing a complete stock rom maybe impossible. I think Odin checks the model name, and prevent the flashing if they don't match (Just guess).

Yeah I tried flashing the modem only but when odit checks the PIT it fails straight away. Did try flashing the full stock package but again no joy. Its annoying as people with G920i dont seem to be suffering the issues that the G920F has with poor cell signal. Its definately a phone issue as I am on my third one lol. Have flashed the brand new modem package that was released a couple of days ago but has mad no difference at all surprise surprise. I think your correct though as odin must check the model number before flashing. Hopefully a dev could come up with a way to bypass the check as like you say the modems and hardware are identical on both models. The only difference is a couple of basebands which from my research are only software locked anyway.
You cannot flash G920I modem to a G920F and vice-versa. They are not compatible.

So I guess g920i and f have different partitions. their partition for radio may have different sizes As I found the modem.bin of these two models are In different sizes.
Hello,
I bought a galaxy s6 in Latam (g-920i) before returning to Europe (Spain). It is network unlocked, so it works perfectly. Turns out that the Latam firmwares (g920i) for marshmallow are being left behind in comparison to other regions as Europe (g920f). I have compared both phones (i/F) and they are identical, so I am feeling moved to flash a g920f firmware on my phone. When I try it, it fails. In the very beginning, I thought that it failed because the model name was wrong, so once rooted, I changed it in /system. Nothing happened, so I am assuming that the firmware fails because there is some sort of different partition set between g920i and g920f.
My question is, if I flash a g920f pit file on my s6 (originally g920i), will it firstly not brick it, and then enable me to flash a g920f firmware?
Thanks for your help.
Be good boy and never mess your device flashing stock fw with different phone version. BTW this is belong to Q&A section

I know your feel
Just wait 2 week and we will get marshmallow on our 920i and don't brick you phone
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 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.
Hi I'm new here, I'm having a problem choosing the correct firmware to flash on my s7 g930v because I live in South Africa an from what iv gathered g930v is for USA an that g930f is what we use in SA. Am I on the write path so far? I bought the S7 2nd hand an the previous owner tryed rooting it but I think he used the wrong firmware cause it had g930f and the motherboard has g930v written on the actual board. So what I'm asking is how do I check what firmware I have to flash to the fone? Cause the firmware info that I get are the firmware I flashed with and I'm getting pit error in Odin an only combination firmware is work on the fone. I need South African networks to work. If any1 knows what I should do would be of great help.
Thanks
Boot into recovery and see what it says
