Convert G920F to G920I - Galaxy S6 Q&A, Help & Troubleshooting

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.

S6 regional firmware + pit files

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!

[Q] Flash SM-N915W8 (Canadian Note Edge) firmware onto a SM-N915V (Verizon) phone?

I'm thinking no, but wondering if it is OK to flash a stock Odin fw that is different from the device's carrier? Has anyone tried this? From what I recall from other Samsung devices, worst case is it would fail but not brick the phone. But still want to see if there's any feedback for this phone.
Have a SM-N915V here (SIM unlocked) in Canada and would like to flash a Rogers stock fw onto it if possible.
I guess NO
Reason : both the device have different partitions(that is the only thing i guess). if partitions can be matched it can be tried as hardware is more or less same.
Still i would suggest take a full Nandroid backup including the efs, and flash the firmware, even if you brick you can recover.
Thanks. I assume this is where .PIT's come in - but I understand the danger of force-flashing a PIT of one model to another model. Too scared to brick. Will stick with Verizon firmware ;D

Possible to convert flash SM-G930U firmware on a SM-930P?

Hey guys!
Yesterday I got a Sprint carried S7 SM-930P as a gift. The only problem is that although it works flawlessly on my sim cards (I'm not in the US), I found out that the 930P won't get the 7.0 update. Is it possible to flash the G930U firmware without messing my phone up?

I wouldn't do it unless your absolutely sure, I wouldn't be so sure if it's for a different model number. If they were able to have the same firmware flashed Samsung would just release it, they obviously didn't because it requires extra effort, pointing towards the conclusion that the firmware is not flashable on 930P

You can flash it, i have done it myself. There are many guides over here that tell you how. All S7s in the USA are the same exact thing hardware wise, only the software (firmware) is different. Am currently running SM-G930U firmware on an SM-G930VL S7. @op the sprint s7 (SM-G930P) already has android 7 as of last 3 weeks

SM-G930P converted to SM-G930U
Hey guys. I was able to flash the sm-g930u firmware downloaded from sammobile... the problem I have now.. I have a blank csc. No product code.. and on software updates it fails to register my device. Also in settings . I have some weird options. Which some of them are repeated. I will upload screenshots.. Also there's a system UPDATE option and also software option. Which one of them fails to register and the other only works with Wi-Fi. Should I revert back to my stock sprint firmware. If so do I need to wait for a firmware with same build date or newer. Because on sammobile haven't uploaded a firmware with a build date on par with the current install. Then I would have to wait right. ? If using a older firmware it will brick or do something to my phone ?​

Did you flash all file in the SM-G930U folder (AP,BL,CSC,CP)? Because i did it with T-mobile,Verzion an it work fine
Thanks for the reply. Already solve.. what happen i flash home_csc. So ir was like that. But then i made a back up.. and flash again using the csc file. And all work perfect. At first phone was with the SPT csc.. then after i restored phone and pop in my sim it did something.. and now I'm with XAA csc. Works perfect. And could receive updates (phone registered). Just waiting for the july security patch update. Btw phone works better in every way.. battery even last longer..

Hey Buddy. I would recommend doing a full back up on your phone., using Smart Switch app
It saves all your numbers, message, etc..
Then proceed to flash the latest firmware for the Region or Provider. Using (CSC) not (home_csc) which means flashing the csc will wipe your phone data. Phone will be like new again. Proceed tru set up. Loggin in gmail. Proceed to update smart switch app if not found in apps. Then restore from the back up file. And good to go.

actually all S7 are not the same hardware fyi. The Sm-g930p has chipsets snapdragon and uses cpu procesaor quad core but the sm-g930F has the chipset Exynos8 cpu is octa-CORE the chipsets vary from these two. Flashing firmware for one chipset to the other may cause major problems bot to mention bootloops.. but I looked up sm-g930U and it uses the same processor as the P model.snapdragon

He said all S7's in the USA are the same, which is correct. Exynos/930F isn't sold in the US, only way to get one is to grey import.
You can flash any USA model's firmware onto any other USA model because they're all the same hardware.
anyone running the 930p with current update how did you get around the binary 6 lock all the 930U firmware versions I can find are binary 4 I think t-mobile is 5. Anyone got links to a firmware we can push to sprint variants that are binary 6.

You can't get around it. It is currently impossible to "downgrade" the bootloader binary version. All US carrier variants are version 4, except Sprint that is 6. You are stuck.
The only way it would ever be possible is if (a) one of the carriers, in a future software update, increases their bootloader version to 6, or (b) if someone figures out how to unlock the bootloader for the Snapdragon models.
Neither of those options is likely to happen, ever. You might get lucky and hope the G930U unlocked version has a higher number (it hasn't been released for Oreo yet), but I wouldn't bet on it.

Blame Sprint; there is really no reason for them to do what they did except keep users from switching their phone to another carrier. This isn't a Samsung thing. I don't believe you would be able to do this with any other Android phone, either (i.e. go backwards in bootloader versions).

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?

Changing CSC code from a different model number

Hey Guys, I am in desperate need of help.
So I bought the note 20 ultra (model N986-U) from a seller in Texas (I live in Canada). The phones original csc code was ATT/ATT/ATT. I have a rogers sim card (csc code RWC). I noticed the phone is still stuck on One UI 2.5 because I am not connected to the ATT network.
So I tried changing the CSC using SamKey. I bought some credits, followed the steps and now for some reason my CSS is XAA/XAA/ATT.
I understand now that my phones model does not have a RWC firmware. Frija can't find the software for the SM-N986U running RWC but has no problem finding the software for the SM-N988W running RWC.
Is there any way for me to update my phone without bricking it? In an ideal world I would get OTA updates. Can I download the CSC_HOME file from the SM-N986W and flash it on my SM-N986U?
I'm really sorry for the noobish questions, I read so many threads and watched so many videos but I don't have the balls to experiment with such an expensive phone.
I know you can flash U1 firmware on a U device without any issues.
That's what I did to mine.
As for flashing W software on a U/U1 device, it's technically possible considering they are identical hardware, but I cannot say for sure what impacts it might have to the phone's performance.
You can always manually flash current U firmware.

Hey thanks for the answer,
I ended up flashing the W firmware on the phone and it worked flawlessly! Now the phone shows that it's a model N986W. OTA updates still don't work tho, even though the csc shows RWC

Glad it worked. Grab the latest firmware for RWC and then wait for the next update. (N986WVLU1DUB5)
