I recently purchased a S9 from Cricket during their last promotion. I'd like to flash U1 on it as it's what I've used with my S8. Does anyone know if VoLTE and Wifi Calling work when using U1 firmware on Cricket. I remember reading somewhere that Cricket only supported VoLTE on their phones bought through them and the restriction was IMEI based. So I feel good about that working, but I'm unsure about Wifi calling.
Hi, did you get anywhere with this? I have a U1 S9 and I don't want to flash the carrier branded firmware but I've heard VoLTE will work on the U1 (unbranded) S9s on Cricket (and AT&T)...

to my at&t s9 sm-g960u
now as obvious - it is running T-Mobile software.
How do I revert or change this to normal?
I want to have my at&t firmware back and VOLTE wifi Calling etc,

You have to flash the U1 firmware, then flash the AT&T G960U firmware. Same way you flashed T-Mobile, just in reverse.
Msg me i would like to help you to restore your device
Can a unlocked Galaxy S9 with U1 firmware be activated and unlocked on sprint?
I've looked up all the bands and radios and it does have it.
As far as I know it should work fine. The US version of the GS9 should work with CDMA or GSM.
If I have a s9 us international version model g9600 can I flash it with the T-Mobile g960u? Would it work and give me wifi calling, volte and video calling also Samsung pay?
Hello,
I have a Galaxy S9, Model: SCV38. Is there a way to enable VoLTE on the phone to be used for Indian carriers? If there is some other post discussion, do point out.
If the correct firmware is installed, then it'll work. If not, then you're out of luck.
You might be able to flash the carrier's firmware using Odin (I did that on my S9+ to get VoLTE working on EE UK, as the phone had generic firmware).
I want to covert my phone AT&T G960U to global rom? Help me
I actually don't believe you really can to be honest. The 960U is the US unlocked variant. So even if you wanted the vanilla feel you wouldn't get it. From my experience, each carrier has been using the same variant of the S9 so they would just rebrand it with a OTA update.
Personally I've switched from Cricket (Original Purchase) to Boost (Boost ROM loaded) to Straight Talk (Verizon) with no issues except one. Which has to do with Sprints activation crap. The latest carrier switch has a default boot screen from Samsung.
You may be able to flash a rom using odin that isn't carrier branded. Like I said though, I'm pretty sure if its activated an OTA update fixes you up either way.
I get my firmwares from Sam Mobile.
