Dear friends
i has s7 g930t unlocked , and indian sim card was working on it.
then, I flashed unlocked S7 T mobile G930T to G930U firmware (downloaded from updato).
Then i inserted my Indian sim card , but it didn't get network.it just keeps on searching network.
Then i again downloaded G930T Firmware , and flashed again back to tmobile. But still i am unable to get network.it just keeps on searching network. when i click on search network, ,it just fails
i flashed both "HOME CSC" and "CSC" that i downloaded from updato fro 930T Tmobile , but still no network.
any help on this?
how can i get back to normal network?
this whole thing happened as i thought 930U may support indian VOLTE

I'm not as concerned about this for ROM flashing. I'm wanting to find out if my G920T can use G920I or G920F modems/bootloaders, etc.
Here's my deal. I have a T-Mobile G920T. To unlock this phone I need to get away from the G920T modem. I previously had a G920T1 (MetroPCS) firmware set installed and it worked great, but the rom sucked.
I've since restored back to stock G920T and i've rooted/twrp, but I see other ROM's and I'd like to give them a shot. The catch - they all say I need to have the newest OI7 firmware installed. I'm still on the G920T sim locked OH8. The only OI7 modems/bootloaders I can find are for the G920F variant. I can't find OI7 for the G920T1 variant. I don't know if the G920F variant will sim unlock my phone. I don't want to brick my phone to figure that out, so this is the reason why I posted this question. I can flash ROM's all day long, but if I can't use my Cricket sim when I'm out in BFE then the ROM is pointless.
Does anyone understand what I'm asking?

DO NOT flash any FIrmewares through odin if its isn't your model number, if you purchased your phone and don't have an EIP you could sim unlock with the app, so any rom your on unless its not Touch wiz based (aren't any available besides touchwiz)
Hi Guys,
Does anyone know if it would be possible to flash an EE (EVR CSC) onto my rooted BTU 6.0.1 firmware? The BTU 6.0.1 firmware doesn't support EE VoLTE. I don't want to be on EVR firmware because it messes up my dual sim model (G930FD)
VoLTE became active on my EE G920F (BTU) earlier today. I'd been asking the same question as you for a few days. Was messing in the settings, disabled and reenabled wifi calling and it just happened. Phone rebooted itself and VoLTE was active. Tested with a few 4G calls to confirm.
None of the ims files were changed but there is a new APN named 'ims' in the settings. It isn't selected active but it is there - it wasn't before.
Yes, the phone was bought.from an EE shop and still carries the original IMEI. So I believe as long as your phone was bought from an EE outlet you will definitely be able to use VoLTE sometime soon.
Currently running the CarHDRom V.27
Have an unlocked tmobile s8 active I'm using on the AT&T network that I'd like to be able to use wifi calling on cause i get lousy cell reception at my place, is it possible to flash the AT&T fireware onto the device? ive already tried using odin and the stock AT&T 8.0 android oreo firmware i found in a different thread but it fails.
Im in US , i have s7 G930T (Tmobile), carrier unlocked. At some point i needed Polish cell number so i came up with idea to have Orange sim card (its Polish cell carrier) shipped to me and install on my cell so i can make calls to Poland over wifi calling. When sim came and was inserted into my s7 it displays ATT carrier and wifi calling is no longer there, but i kind of expected it , tmobile kind of sucks when you try to use phones from different carriers on their network or vice versa. So using odin i flushed it with xaa rom (it should be stock us rom), then with att rom, both times wifi calling was not there just like with tmobile rom. Then i tried to flash it with Polish stock s7 rom and then with Orange s7 rom, both unsuccessful flashes (partition fail).
Does anyone have some idea what i should try next ?
PS s7 is my old phone , currently have galaxy s10e (G970U version), funny thing is when i put new Orange sim into S10e everything works fine, wifi calling showed up without a problem.
Any help greatly appreciated. Thank you.
If I recall correctly VoLTE and VoWifi config is part of the CSC device firmware on the S7, which means you'd need to flash the polish firmware.
But the US model is a different SoC (Snapdragon instead of Exynos) which is why the flashing fails as it's not the right firmware for the hardware. I'm not sure there's any way around it.

Beanvee7, thank you for response, i kind of figure that much, I just had some hope there is a way around it somehow, especially since with my s10e i have same scenario ( us tmobile phone and Polish sim) and everything is working fine. Thank you again.
Looks like the S10 still has the CSC firmware, so I can only guess it no longer relies on carrier config in the CSC for VoLTE and VoWifi. But it's always been how the S7 has worked and commonly asked.
Hello, I have an unlocked Galaxy Note 20 Ultra from Verizon. I am wondering if it is possible to fully convert this device to work fully with TMobile I was specifically wondering if it's possible to use TMobiles 5G Network on this device. I have flashed the U1 Firmware to the device but it never showed me an Option to choose my carrier or anything like that, and even though the Signal shows 5G whenever I turn a speed test or view the cell info it pops up as LTE
You need to change your device CSC to TMB and flash TMB U firmware, not U1.
You device currently shows VZW/VZW/VZW in your screenshot.
It should read TMB/TMB/TMB, or at least VZW/VZW/TMB.
The SIM card itself will determine what network you have access to.
Be careful though as you have now flashed newer firmware with the new version 2 bootloader.
So you can only use firmware with that bootloader version. No going back.

If you change ur CSC from VZW to TMB, then it will read TMB/TMB/VZW in your screenshot.
You can only change to TMB/TMB/TMB if you root your phone .

Please note, some codes in original post don't work for some, with latest 10.1 Update.
Using Sammobile, I've seen U1 firmware with a T-Mobile CSC. That way you won't have all the T-Mobile apps or boot screen.
