What can go wrong flashing a modem file from another s6 variant? - Galaxy S6 Q&A, Help & Troubleshooting

I have a USCC Galaxy S6 (SM-G920R4), and all of the ROMs here don't have any support for it as far as I know. I was able to flash XtreStoLite and everything was working fine with the exception of the mobile data and voice. Is it possible to flash a modem from another device to get this to work? What are some options for getting the mobile data and voice to work?

Nope. The bootloader has to match the modem for it to work.

so there are no options

You could try the Sprint section since your network is CDMA and not GSM.

so I would need to flash the sprint bootloader and modem with odin?

No just try the rom. It may fix your data issue since its CDMA too and if you're lucky sound may work too.
They may even be identical models!

yes i'm in the same boat, except mine is working. i have root and what not but i just want a clean rom like phantom blazer. but when i installed it everything worked freaking awesome....except no cell signal since its geared for sprint only, i wonder how hard it would be to adjust it to US Cellular.

Here is the rar file from my dropbox for CWM backup of my phone. (The file is being Uploaded)
https://www.dropbox.com/sh/ucd5lxmup5ibnxk/QxnDuVDtE8
There is one more way
Just odin the Verizon system rooted unlocked image. tar (1500 mb) Its rooted system image of Verizon. It works fine for me. All Verizon custom ROMs work too. Stock ROMs fail at the modem stage. Once the boot loaders are unlocked they will load too.The baseband remains of US Cellular.
MD5 file Question
There is a Kies updated for USCC phone. Kies downloaded a file and placed it in the Binary folder.
Named "VZW_HOME_R530UVXALG4_R530UUSCALG4_961795_REV00_user_low_ship.tar.MD5" can this be flashed using ODIN to create a stock phone. Sorry new to flashing

Can SCH-R530 be used on GSM network?
Hello,
Can the US Cellular SCH-R530 be used on GSM network? I read about the Verizon SCH-I535 being turned into a world phone. The AT&T rom can be flashed to the SCH-I535 and everything works. I think the only thing that cannot be flashed is the ATT modem into the verizon S3.
So can something like this be done to the SCH-R530 phone?
If anyone is willing to try or has any input, please let us know.! Thank you..

Are you sure the Verizon ROM will work smoothly in Samsung S3 R530 US Cellular and not brick the phone?
Is the Verizon S3 I535 and USCC S3 R530 have the same hardware?
thanks,

If you haven't found help yet, this should fix you ups. All you have to do is install CWM via Odin and then flash one of these!

[Completed] [Q] Flashed CM12 To Galaxy S5(SM-G900F) and now I have no cell service

Hey everyone. I recently flashed the new CM12 rom to my Galaxy S5 and mostly everything works fine. The only problem I have is I can't make calls and/or send text messages. My carrier is Sprint and my model was formerly SM-G900P however after I flashed CM12 it now says SM-G900F. Whenever I click on mobile plan it says "Sprint has no known provisioning website". I can't even access the APN settings. Can someone please help me fix this, I love CM12 and would rather not go back to stock. I have no problems with my IMEI/MEID number, and under Status in settings my phone number still comes up however for Network it says "Searching for Service" and for Mobile Network Type it says "Unknown", it also says "Disconnected" for Mobile Network state. Is their any way to fix this?
Hi
Thanks for writing to us at XDA Assist. From what I can see you have the Sprint S5 (CDMA) but it looks as though you've flashed a ROM for the GSM model. GSM and CDMA are totally different mobile technologies so using a GSM ROM on a CDMA device will result in exactly what's happened to you. Where did you find the ROM that you flashed? Can you provide a link please?
Your device forum is here:
Sprint Samsung Galaxy S 5
Make sure you bookmark that page. Make sure you only ever use ROMs/kernels/mods/modems etc from within that specific device forum for your device. There are many different variants of the S5 and you can't mix and match ROMs, this time you probably got lucky but flashing the wrong firmware can very easily brick your device.
Thread closed.

Honestly, I'd say to factory reset and Odin your correct version firmware. That way the firmware will be compatible with your Sim and Network.
Oh ya. Try to stick to the firmware that belong on the phone.... LOL. Let troubles that way

remove simlock with root??

hi, i have a sprint note edge probably it can be rooted, but its possible to remove the simlock for international use??
I have seen a sim unlock option with galaxy tools app. Dont know if it works just know its there. I was going to ask the same question about domestic unlocking.
So anyone got answers i would like to hear. I read note edge was gsm/cdma capable like the nexus. Please someone who knows chime in. Looking to get domestic unlock because i am sure it isnt easily done through sprint.
Secondly i tried to root it whith the odin/chainfire and it didnt work. Git the error message after failed flash and had to re do the stock firmware with odin. Anyone got a link to the chainfire maybe i downloaded the one for kitkat?

Wifi calling

Hey guys just wanted to see if there is an option on our international duos version for wifi calling? I remember on the s6 there was something I had to enable. Is it the same for s7? Nothing in wifi section about enabling it. I need it for T-Mobile side of sim#2. Any help is always appreciated. Thanks
You need to install the Spain firmware. The option is on there. I don't know if it works
