Samsung SM-G930S... all the same as

I have a Samsung SM-G930S... which is Exynos 8890.
Can I then put on any ROM from any other Exynos 8890 based phone? And all will be well?

All will be well if you enjoy a brick
Only flash stock ROMs for your model S7 (G930S)
Bootloaders etc are different between models, it doesn't just depend on the chipset

If custom roms, then yes. I have a G930L. Same korean variant as S & K.

So then you stick to L, S and K supported custom ROMS? ...
I see quite a few custom ROMs for the G930F version but that would unsupported/dangerous?

That would be fine. Example custom rom for korean variants are superman rom, superstock rom. I'm currently using superman rom

012512, thank you for your answer. I will look up those two ROMS. This rooting of the Samsung phones seems a bit more complicated than the last time I was rooting, the LG-G3 and the OnePlus One, or is it my imagination.... or just getting more-forgetful?
When you look for ROM's compatible for your phone, are you looking specifically that they are for the SM-G930S, or exactly what are you looking for? Other non-Korean variants that will work?
Thanks again.

Any custom tw roms will be fine. Take note that aosp roms are no longer supported for korean variants.
S7 korean variants are g93xK/L/S
So if you install a g930/5F custom tw rom, you can install it on your phone as long as you don't install the stock g93xF/FD roms.
Also, there is a separate twrp for korean variants in order to install a custom tw roms. Please refer "heroltekor" twrp.

Excellent information, thank you. By trial and error, before picking up your post, I put on an Exynos Infinity 8+ from v8. It seemed to flash fine using the default Bixby CSC indicated in the setup. I did this last night so have not had time to chck out all things, however, cell phone, messaging, bluetooth all work just fine. I'm about to clean install the v17 of the Infinity in a few minutes. TWRP is a a** saver and my friend.
Thank you, again.

Hi,
I bought Samsung Galaxy S7 SM-G930S from the store which was converted into SM-G930FD as I was not having Korean sick apps installed in my mobile and there was no Korean logo of "BANDLTE" while switching off and switching on, when I saw my phone model name it was SM-G930FD and was supporting dual sim both had a same IMEI. But when I restarted my mobile after getting home phone got locked with this message "Custom Binary Blocked By FRP Lock" so decided to got into boot menu there I saw SMG930S written so i flashed mobile with SKT Korean firmware of smg930s but when I installed it I got tons of Korean apps and getting "BANDLTE" logo while switching off and on my phone I lost that Samsung Original logo which I had when my phone was converted into smg930fd. Now I want to switch back to Smg930fd settings/firmware so get rid of these Korean apps and Model to be appear as SMG930FD as the back of my Samsung Galaxy s7 glass has a phone model SMG930FD. I don't know Shopkeeper scammed me or what I told him I wanted to buy SMG930FD but he gave me this converted phone Kindly help me to get back to SMG930FD firmware/settings

Same case for me, one thing different is that i bought the phone used from some random guy on the internet, i tried OTA to get Oreo as the phone had Nougat but it says no update available for me, 4G didn't work on my netword too, then when i saw samsung health not working i thought knox probably is voided when i checked odin i found its a 930S instead of the FD.
I do believe there is ways to convert to the 930F/FD by flashing select flash, using a box/dongle or some paid tool like R3 or Chimera or whatever you can get your hands on. I work on a repair workshop, have those i mentioned above and i saw this feature where you can actually select which part you wanna flash from a specified md5 file, i didn't test it on any phone yet, but i think they flash the bootloader of the real variant 930X but they put the AP of the international version 930F/FD, from the AP file you can also select what to flash and what to not, so you can actually only flash system.img of the XXXF version and the rest can be from the original variant. Never tested it but i think that's how it works.
My advice is to return the phone, that's what i'm going to do as i just bought it today (i was a happy dumbea** already bought few cases and whatnot...) the phone is still good and all functions perfectly, 4G might not work on some networks due to the different bands but everything else is the same! there is a big chance you can get the international firmware on it and be happy with it, but there is always a chance of breaking it too! or getting a network lock which i guarantee you, you're not going to like...
I don't know if this type of phones is refurbished, but i really hate that Samsung actually does that or allow this to be possible (happened before with an S6), same goes for LG too (Had a v10 korean model with Tmobile firmware).
Again, my advice, return it!!

Okay so here is an update on my case, might help anyone. if you did read my previous reply you'll know that i bought the phone from someone online, contacted him back he didn't block me nor ignore me, he even called me himself, but he bought a ps4 with my money and can't go back. Still waiting to see if he can get the money back, but what i was thinking is to ask for few dollars back just cause 4g network and dual sim functionality doesn't work on the phone, again its a 930S with 930FD firmware, after confirming and playing around its actually 930F not FD so i think i can get back the dual sim function. I'll be flashing the phone if i got no money back, try to get FD or 4G working on it and sell it for maximum price, then use the extra money i'll take from him to sorta re-gain my money and try to find a better one.
If i ended up flashing this 930S to a 930F or FD i'll post the method and the result and link it in another reply for anyone interested.
Wish me luck.

Bro I found a way you can download custom rom of smg930fd by installing TWRP or CF auto root method in this way your model will I guess automatically turn into dual sim supported and model will be shown as smg930fd.

I also have a 930S. How to >Bro I found a way you can download custom rom of smg930fd by installing TWRP or CF auto root method in this way your model will I guess automatically turn into dual sim supported and model will be shown as smg930fd.<

Hi,
I'm facing the same situation. I bought G930FD dual sim but later I found that it's actually G930S.
Now I want to install its stock firmware which is Android 8.0 by SK Telecom, Korea
Can you please tell me:
1. Changing the ROM will covert the phone into Single SIM version?
2. The phone will lock to Korean network only?
3. This will change everything into Korean?
Cheers

1. Yes it will!
2. This one depends if your phone is unlocked or not, most of the time it is unlocked.
3. The firmware is all the same Korean, US, Canada or international the biggest difference will be in bloatwares, as I had that phone before I can tell you, you'll have many SK telecom apps.
4. (this one I added) If you flash your phone with the original Korean firmware which is by downloading the firmware for the S7 SM-G930s from Sammobile and flashing it using ODIN, going back is quite hard! So if you're network locked or you want the dual sim functionality back, you'll need a special tool/dungle called Z3x to make the thing work!
5. (I also added this) To unlock the phone and make it work on all networks there is a process called "Patching the certificate" and it requires an unlocked bootloader which probably you already have, and root! and most importantly! it only works on Android Nougat. Basically what Im saying you can only have dual sim function in Android Nougat with the 930FD firmware, also if you flash the original firmware and its network locked, if you wanna go back you'll need that tool I mentioned and again, only Android Nougat.
Had that phone before, still have the firmware backup for the 930StoFD also. I can help if needed.

Thank you for such a detailed answer.
Now I'm confused to select a blue pill or red one
At one hand the current OS is outdated and have a very annoying and UN-stopable adware buit-in; but it's dual SIM
and on the other hand I may have an updated and ad-free OS by sacrificing dual SIM functionality

What you can do is install TWRP recovery, you can download it from "twrp.me/Devices" and look for your specific device, backup everything and transfer it to a PC or a memory card, just in case you'd like to go back later, then you can flash the original firmware with Android Oreo and see if you like it more and if its worth dropping the dual sim for! if you don't like it, you just reFlash TWRP as it will be erased, format the partitions and restore the backup, You'll be back with Nougat and dual sim function but the network won't work till you patch the certificate (used to be called repair network), and for that you'll need root, debug enabled, and the z3x. Your issue will probably be that last one, z3x, cause as far as I know you'll need this tool or a similar one to get the network to work again! and just to mention, for some reason, if you erase the dalvik cache or reset the phone, you'll have to patch the certificate again.
Just think it through carefully, I work in a repair shop so I got access to lots of tools, but in your case if you don't, it might be quite hard to get things working again if they break.

I simply flashed my device using Odin.
These is no more dual SIM functionality but I'm happy to have a latest firmware for S7 and I'm fee from the ads now.

Happy to hear the issue is solved.
Couple of things you can try for a better experience if you like modding and tweaking.
If you have root and magisk, you can install a module that enhance your camera, it will increase the quality and add some extra features (I just installed it three days ago on my S8+, and the S7 is also supported, love it)
You can install a sound mod that gives you stereo like sound by using the earpeace and the bottom speak together.
Also with root you can patch your host file (Luckypatcher can do that) to block like 99% of the ads within the apps (I can't live without this one, life saver)
And can find tons more withing the forums, these are the ones I tried myself.

If I flash unbranded FW on a carrier specific device, loke tmo or att for example, would it sim unlock the phone?
If I flash tmo FW on an att s8 would it in turn allow me to use the att original device on tmo? I ask these questions because I feel like it would work for both my questions since flashing the FW flashes both boot, kernel and baseband/radio. The which is needed for signal. Just some theories but would love to know the answers.
Btw, I have a F model S8+ and was planning on buying some US branded devices so I was curious.

No, it will not unlock the phone (Note: Verizon phones are factory unlocked and remain that way after a firmware flash)
Yes, you can flash any carriers FW to a US S8 and use it with a different carrier.

So I understand, your saying if I flash att FW to a T-Mobile s8 I can use it on tmobile? If that is the case, to me that's an unlock of sorts tiny book lol. Just wanna make sure is all

Just realized the typo.....what I meant was, if I flash ATT on a TMO variant I can use ATT while locked to tmo? I'm very unfimiar with combination fw and always opted for the UK models for alot of reasons. Sorry for the confusion of my op question. I know on the s7 and edge if you flashed the US unlocked firmware it not only removed AOL bloat but it unlocked the device. So that is why I ask.

I had a TMobile S7 edge and flashing unlocked firmware never unlocked the device. That's handled by TMobile servers so...
Flashing unlocked firmware will give you just that. The smoother, bloat free firmware from another device but not the actual sim unlock.

I bought an unlocked device and wanted wifi calling so I flashed the g950usqs1aqf7 att firmware with Odin and it worked to enable wifi calling but I'm unable to get any ota updates and I hate the bloat. Is it possible to get WiFi calling with an unlocked firmware like this one? Also what is the difference between the U and U1 firmware variants?

There are plenty of threads on this, but I don't think anyone was ever successful. I flashed att Oreo to my u1 and got the options, but can't get my company to change my imei back.... My personal phone sim works fine. Quit at that point since it's an Ims registration error. You can try merging the wifi calling apks, but I'm pretty sure it's baked pretty deep in the os. The Verizon guys got some of it working. You can try their threads and see if any of it applies to us.

Thanks. Some threads made it sound possible but inconclusive. I'll just assume it doesn't work.
BTW, can you link to the att oreo fw? And what do u flash that with Odin or comsey?

The thread right below this one entitled Oreo ota has all the details and it needs to be side loaded through adb. Not Odin. But you will need to Odin the 950u base to get off u1

Ok thanks. I need to flash anyways because I'm having terrible battery issues and just debating whether to go to a newer version of 950u or back to U1 and losing WiFi calling. In your opinion is oreo beta worth it

So just to confirm, I have read everything, but I am just a bit confused. If I flashed the unlocked firmware via modified odin on a locked AT&T S8 it will remove a lot of the carrier bloat and give my my wifi hotspot back, but remove wifi calling. Similar to when I flashed the T-Mobile firmware on my AT&T S7 and got rid of a ton of the AT&T bloatware but was able to activate my wifi hotspot but lost wifi calling. I stay locked to AT&T which is fine that is not my purpose for flashing

The links don't work. Any chance you've still got the firmware? I've been overseas since october. I have an unlocked AT&T phone that I intend to keep using when I get back, so I want to keep it AT&T FW.

Hi.
I have a G955U Galaxy S8+ AT&T Factory Unlocked on Android 7.0
Baseband Version: G955USQU1AQD9
Android Security Patch Level - April 1, 2017
I no longer live in the US, and currently in the Philippines. Phone works great and the signal is too and all, but I cannot get OTA updates.
Can I just download the firmware file in this thread and flash straight through ODIN, or do I need to follow another guide?

Sprint S8 Active flash to T-Mobile?

So i've read that the sprint version of the S8 Active is on bootloader v5 and the T-Mobile version is bootloader v1. Is it then possible to flash the T-Mobile firmware onto the Sprint Variant ?. The device is already unlocked but i would like Wifi-calling to work for T-Mobile.
Edit 1: Found this and successfully fully flashed from Sprint to T-Mobile(everything works including Wifi Calling). Only works if you are on bootloader version 1.

No apparently the bootloader version must match or be lower so in this case sprint is higher so you can't flash. I've tried and downloaded the tmobile oreo firmware; you'll just get a fail in odin

That is the part i am maybe not understanding. My Sprint S8 active says it is Software version G892USQS1ARC1. Doesn't that mean it is bootloader version 1?

Sorry I was wrong! I actually flashed it! Very happy right now. I was being stupid and using an older version of odin before. Now I successfully flashed sprint to t-mobile oreo with no problems! Use Odin 3.13.1; not prince comsy mod or anything else. So it was bootloader 1 after all; there were some misleading posts without proof. I will trust the software number from now on

ARE YOU SERIOUS?!?! Does wifi calling work for you now?

I'm not sure. How can I check? I'm on Fido which is Canadian carrier without WiFi calling. I'm guessing I'm supposed to be looking for a tmobile WiFi calling app. See attachment screenshot for proof. Still recognizes my phone is from sprint

Yeah i just finished flashing it and i get the same as you. Phone still recognized as Sprint and no WiFi calling. Darn. Android 8.0 Oreo is a huge plus however.

I think we need to follow this guide to change carrier but the thing is there is no factory binary for the s8 active so this guide won't work until there is one...
https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487

Actually I have found and flashed a factory binary trying to change it to T-Mobile. The problem I ran into is they want you to download the firmware with "w" after the model number. That is what I think let's you change the option after typing in the code. That firmware is only for s8 I think(not active as it has the s8 model #). Without flashing that, after I typed in the code the only option I had to choose from was sprint. No "xac" or whatever it was.
If I am not mistaken. The model with the "w" is the Canadian version of the s8. The s8 active is US only I think.

So Im getting ready to pick up a Sprint version to use on Att or Tmobile (good deal). Are you guys seeing any issues after flashing? Thanks

The only thing I've notice is there is no option for mobile hotspot( i don't think it was there to begin with, i could be wrong however). Other than that it works perfectly. Great battery life and everything. Flash the userdata to get rid of the Sprint Boot animation if you'd like. I did it and now there is just the "Samsung s8 Active" logo, then lock screen. Goodluck.

WiFi calling works fine on T-Mobile without flashing to T-Mobile firmware. Only issue is that sometimes it gets stuck enabling WiFi calling requiring a reboot. Band 12 also works, its in the Sprint specifications. The big question I wonder about is if band 71 can be enabled.

Did you follow the video I posted?. Ignore all the other comments about things not working. When i updated the OP with the link, it fully flashed the sprint device to T-Mobile. The only thing you have to watch out for, is if your Sprint software is running a new bootloader. You can tell by looking at the baseband version number. This will only work if you are on bootloader 1. My baseband is currently "G892USQS1BRD5". The bootloader version is the 5th character starting from the right. The number 1 before "BRD5".

At&t branded phones on Tmobile network

My wife works in a hospital and we used wifi calling because reception was poor.
It's still poor with Tmobile but no wifi calling. When we moved from At&t the wifi
option was greyed out. Tmobile states that it works fine on their network.
Is there any way to get a samsung s7 g930a and a samsung j7-j727a to use wifi calling
on the Tmobile network?
I'm sure it will probably involve something over my pay grade but I am willing to try
anything needed to get this feature to work

If your current firmware has WiFi calling (Volte) You can only use Volte if the network supports it. There are however many apps you can use for WiFi calling look on the play store.

Not sure what volte is, I have had some other issues with the
service that I thought might be resolved by installing a
different rom
Tell me if i'm wrong
Thanks

Volte is wi fi calling over a network which the network operator supports without the need for a specific app.
Please tell me exactly what you are trying to do
What network are both phones using?
Which networks were the phones on initially?
Have you modified the phones in any way? Root? or TWRP?
What firmware are both phones currently using? Go to Settings>about phone>software information>baseband version G930A????

Sorry for not getting back sooner
Both phones are currently on Tmobile network
Both phones were originally on At&t network
No modification
Samsung s7 g930a baseband version G930AUCS8CRL1
Samsung j7-j727a baseband version J727AUCS4BRL1
Note: Wifi calling was available on original at&t network but is now greyed out on tmobile network

Ok since wi fi calling is network specific (some have it some don't) you either need to have unbranded firmware on your phone so it works no matter which network is providing it, or you need to now flash T Mobile firmware for it to work again on your phone.
US networks are a nightmare when it comes to this sort of thing and it's a right pain in the a** to solve it. So what you need to search for now on here is how to flash different firmware on AT&T S7. You should always try to flash unbranded firmware so everything works easily, if not it will have to be T Mobile Oreo.

Ok, If you think unbranded is the best way to go can you point me in the right direction

updato.com and sammobile.com both host firmware and have flash guides. SamFirmTool also is good for downloading firmware, but only lets you download the latest version and isn't as user friendly.
For unbranded you'll want to look for G930U firmware.
For best compatibility you flash all 4 files using (AP,BL,CP,CSC) this will wipe the phone clean. Otherwise you can try Home_CSC instead of CSC (So AP, BL, CP, Home_CSC) , which keeps your data but may not fully resolve your issues.

What beanvee has said but I think it's worth mentioning I find Sam Firm tool pretty straight forward to use and you'll always get the firmware in separate parts which can be useful.

I found a link for the G930A here
I'm not really understanding the differences in firmware. How is flashing with this firmware
any different than what's on the phone right now?
I am just trying to get the wifi calling to work, How is flashing it with at&t version firmware going
to help me on the tmobile network.
I guess I don't know what I need, stock, unbranded, official or custom rom.
I checked all sites listed and there is no firmware for the J727a, alternative?
I would rather someone more knowledgeable guess what I need to do, if that is what is
necessary because the phones are no good to me without that feature. Any suggestions
would be appreciated.

Each carrier deploys their own CSC file, which contains carrier specific configurations, and its this file that determines if VoLTE or VoWIFI is enabled and how it connects.
AT&T may have different VoWIFI settings to TMobile, which is why using AT&T firmware it doesn't work. Some carriers outright disable it since they don't offer it.
Your best bet would be G930T firmware https://updato.com/firmware-archive-select-model?q=SM-G930T&rpp=15&order=date&dir=desc&exact=1
However unbranded G930U should also work because the unbranded firmware is meant to work on all cariers. G930A would likely get you no where since it'll be AT&T specific
The phones in the USA are all identical hardware under the hood, the only difference is the carrier branding and firmware.
But that's only for the S7, I'm not familiar with the J7.

And it's not through lack of knowledge @JohnAtlas, US phones are a nightmare to do anything with. There are several options available but it's difficult to explain what to do and how to do if you are not familiar with how the software works.
There are many guides on how to unlock the software on all US networks, and depending on the network can include multiple steps to complete, you just have to search and read.

Ok, I was able to find the latest firmware for the G930 phone
I installed odin and have the files, BL, AP, CP, and CSC or Home CSC
My question is, Do I load all files and then start or do one file at a time in odin
I tried all files the first time and got failed error and dismatch
Thanks

That is the system recovery and when you flash with Odin you need to put your phone in download mode first press volume down+home+power. The phone should not go to that screen you have posted either before or after Odin, its a completely different recovery mode.
Get your firmware from updato. Com or sammobile
G930U, filter by USA and choose the latest XAA or USC and use the modified version of Odin. We know this works because thousands of people have used it to do what you are trying to do.

Thanks for info, I used G930U TMK version since we are on Tmobile carrier
It seems to be working fine and wifi calling is available
There is no TMK version for the J727U but will try the XAA for the other phone
The way I understand it is that the U means unlocked and the XAA is generic and not carrier specific
Please advise if I'm not on the right track
Thanks for your help

That's brilliant , glad your up and running.
So the letter "U"after the "G930" denotes the region of the world the device is build to operate in, the Americas just happens to be U. The unbranded firmware is the one that has a region but no network assigned to it, so a 3 letter code is used instead, in your case its USC, or XAA.
Europe is G930"F" or "FD" and the 3 letter code for unbranded is BTU & XEA.
Anyway if your phone is running great on T Mobile then don't update it anymore, turn auto update off. The advantage of keeping it T Mobile is you have the wifi calling, the unbranded firmware needs more fiddling around with the get the wifi calling working on the network your using, so best to stick with what works.
I will have a look for firmware for the J7 you have to see if i can recommend doing something with it to get the wifi calling working.
*update*
So it seems the J727 is the same as the J7 in terms of the internal components, everything is the same in both models so that's great news. I think the "27" bit is just a marketing thing.
In theory you should be able to flash the latest T Mobile Oreo to your device from this link https://www.sammobile.com/firmwares/galaxy-j7-pop/SM-J727T/TMB/download/J727TUVS4BRK1/249137/
Now before we start please check / do the following to avoid further problems.
1. Save everything you need from the phone to your pc.
2. Check that you have OEM unlocked in "developer settings" and "USB debug" enabled.
3. developer setting menu is, settings>about phone>software and information>build number>tap 7 or 8 times, developer menu should now appear. (Sometimes it's somewhere else but build number is what you want to find and tap on 7-8 times).
4. To avoid any issues with device FRP lock, delete your google account off the phone., settings>accounts>google. delete it. When successfully flashed you just add the account again when the phone starts for the first time by signing in.
5. Use the same version of Odin you used to flash your S7.
you can also use updato.com (i think it's slightly faster than sammobile.)
Let me know how you get on.
Remember J727T (TMB) is the firmware you want.

Question Weird firmware version on my S21 plus? Some things not working as expected

Hi all,
So, I have a new Samsung s21 plus that I bought. This phone has not receive any updates and I am still on Android 11 Security patch september 2021. Going to download mode, it seems this is a Verizon set but I also noticed my phone does not have similar codes that other phones have. Was wondering if my download mode codes show anything weird.
I am also not able to use Samsung Smart switch, after connecting my device to my computer, Samsung smart switch auto closes(maybe crash?).
Even though this is a Verizon set, I do not have any Verizon bloatware. I am currently looking to install G996USQS5CVCB_G996UOYN5CVCB_VZW which I downloaded from Sammobile, will this introduce bloatware to my phone? Since I am not installing G996U1 firmware, this should not need my data to be wiped right?
Any advice would be much appreciated

CVCB... but I see that the update is now pushed, at first when you posted the comment, I wasn't seeing notice for updates being pushed from VZW. It is the correct version, it was just a delay of information form my end.
Not sure what may cause your issue(s), you can try getting help from samsung by reporting each issue using samsung members app > get help >error report after reproducing or seeing the issue again.

the bloatwares come when you install the USERDATA segment of the software, but I may be wrong. I do know that you can install carrier apps during the setup process, it asks if you want to download the sponsored apps and such... I just can't remember if it comes in the USERDATA or not. You should be able to reach out to vzw and ask for the carrier apps :/ if it's not in the playstore then they'd be happy to share their bloatwares
other than that your device... I think it should say Service Provide Software version : .....OYN_VZW_....
where you running unlocked before?

Haha thanks for the info. I don't want their bloatware but I'm not sure which firmware to flash as I don't want to lose my data and I don't want to accidentally put bloatware on my phone. Any ideas?

first I would check why you have the XAA as the provider software, XAA indicates it was a unlocked device... or had been unlocked by carrier, if it was always with VZW then the last bit of the provider software version should read something like VZW/VZW, VZW/VZW or something similar.
if it has XAA as part of it, then it means it's initially or was running unlocked software version.
such case, yo may need to download the unlocked software version, not the carrier version. I'm just confused because your model number seems to read as carrier locked device... is the Model Number in About Phone showing as G996U or U1?
Also, if you were initially referring to the carrier apps like visual voice mail and other carrier supported feature/apps then unlocked won't be able to get them. only devices that started carrier locked will get it if I'm not mistaking.
I'm assuming at the moment that your device was unlocked and you installed VZW's software hence you didn't get the correct push for the update and still stuck in UI3.1 (just a guess...)

Yeahh. It's weird. I got this phone cheaper than usual and the guy that sold me doesn't seem to know either. That's why I'm kinda confused which version to flash. My model number is G996U and in download mode it says VZW but the phone is unlocked and I don't have any bloatware. So, should I just flash g996u1 software and hope it doesn't reset my phone?

I would try confirming with VZW to see if the device was initially carrier locked and later unlocked. and ask VZW what the best way to go about is.
My guess,... if it's showing 996U as the model number, then just be safe and go with the carrier's version of the software.
BUT as for the carrier apps and other bloatwares, don't expect to get them since the device seems to have been unlocked. unless verizon shares the User data packet with you, you won't get it.
