So for essentially ever I've always been able to enter an IMEI swap with ATT and maintain function with all my Exynos devices
Hopefully same will work with Note 10

Do you normally import an international model? Because this isn't an Exynos device

Yes normally for several devices I have .... and of course calling features are always a bear, even with root
So I was really hoping buying unlocked snapdragon from Samsung wasn't going to keep me from having WFC with att

So Wifi calling works for you? I am using ATT prepaid. Right now ATT wifi calling doesn't work with my Note 10 Plus. It was working on my S10 plus. What I did was switching my SIM to the Note 10 plus with the stock unlocked U1 firmware. Then I flashed my phone to the ATT U firmware with the SIM already inserted. Sounds like I should of insert the SIM after I flashed the phone to the U firmware and not before. Now when I insert my SIM back to the S10 plus, wifi calling also doesn't work anymore. It seems that it has to do with wifi calling provisioning on the network side.

I also called ATT. They told me Note 10 plus doesn't support wifi calling. I find that to be ridiculous.

I've been out the flashing game for a while now. Could someone kindly direct me to a step by step method? Do i use the files provided from the op or use the Sammobile? Any help would be appreciative

I just did the firmware flash to AT&T for my unlocked 10+ and Wifi calling works. Keeping my fingers crossed that it sticks!

Just use the files from the OP. Worked for me now.

Used the following instructions from the International thread to get the steps:

1. Extract (un-rar) the firmware file (i.e. to folder c:\Odin) ***
2. Download Odin v3.13.3
3. Extract Odin ZIP file (i.e. to folder c:\Odin)
4. Open Odin v3.13.3
5. Power OFF your Note10+
6. Reboot Phone in Download Mode (1st plug-in USB-cable to your Note10+!!!), push Volume Up + Volume Down buttons, while pushing them plug-in USB-cable to PC
7. Wait until you get a blue sign in Odin
8. Add the firmware files to their designated slots
9. Make sure re-partition is NOT ticked
10. Click the start button, sit back and wait few minutes

Extract the firmware files from the OP. You should get 5 files:

AP (System &Recovery)

BL (Bootloader)

CP (Modem / Radio)

CSC_*** (Country / Region / Operator)

HOME_CSC_*** (Country / Region / Operator)

I used USERDATA as well for AT&T. Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data.

Ok..I finally got my Wifi calling working on my Note 10 plus despite ATT saying it is not possible. What I did was inserted my SIM to an old iPhone that I have and then inserted my SIM back to the Note 10 plus and Wifi calling started to work right after that. I have a feeling this tricked the system and it thinks I am using the iPhone but I am actually using the Note 10 plus.

As other users have posted extensively, AT&T's system does take a while to detect and process the device/IMEI switch. So eventually, wifi calling will probably stop working

So far after a bit more than 24 hours it still works ....
With my previous exynos devices it continued to work indefinitely

I have attached the screenshot of my phone software information. Appreciate your help which sofware I can download and flash via Odin. Thanks in advance!

 

[burrzoo]

I do have a Win10 laptop but will the flashing process also work using a virtual machine - parallels >Win7 > iMac?

This thread is not for your model. Please post in a thread that is about your specific model number

Depends on how good of a VM it is. Some work well, and others are shoddy

Can anyone please tell me why I am such an idiot and can't figure this out???

I tried firmware from the OP and from Sammobile direct and still can't get the phone to go from ATT to Tmobile. Screenshot below of ODIN with the files.

I got the correct USERDATA file from the OP and put it into download mode with the volume up/down and it loads fine but on completion, get the ATT splash still on original software.

Thank you!

You have to flash U1 firmware first and then go to tmobile one

You guys aren't reading the OP. The steps for going from U1 to U with full carrier bloat, or for going from one carrier's firmware to another, are given right there

I was already on U1 firmware so flashed ASH4 firmware from SamMobile TMB code, and now get the not supported message, am I missing something? Is it nesseary to flash non home csc?
