Is it possible to flash or setup a carrier unlocked S20+ that has Verizon branding (when I boot it, it shows a verizon logo) with an AT&T firmware to be allowed to use AT&T Wifi Calling and other features?

I have a carrier unlocked TMOBILE S8+ , not rooted, Is it possible to flash firmware of verizon or an unlocked firmware and move my service to VERIZON? please help! thanks, do i need to root?
Why would you need to flash anything other than wanting certain carrier apps? You just said that your phone is carrier unlocked. Which means you can take it to a different carrier.
I successfully went to 2ARF4 on this and it's now a G960U1 but I'd like the AT&T wifi calling, is it possible to flash the AT&T software to gain that or does it have to be a AT&T branded device for their system to register it? If it's possible which OS version should I get, I don't see a ATT version of the one that's on here or anything that would be the alternative.
You can get Sprint S9 or S9+ variant unlocked through Ebay:

Also can do Bad IMEI devices also.
After you're unlocked should convert to ATT software when you insert sim.

It hasn't converted to AT&T software on the U1 firmware I flashed. That's why I started the thread to see if anyone else has been able to

First SIM unlock the phone...
Then, Use an unlocked and generic firmware like g960usqs3brj6 and flash with newest Odin.... Use csc NOT home csc and do NOT insert a SIM....
Factory reset, boot phone and setup to home screen... Then just pop in an AT&T sim and click restart device. It should install everything you need for att. I am running att video calling and all other features on my g960u with the above firmware and have no problems... Lists ATT/ATT/SPR under service provider now... Good Luck!
Hey I have a att note 10 I recently got unlocked with a unlock code. I put in a Verizon sim card and service works but the carrier profile and apps aren't switching to Verizon from att.
I got the att note 10 unlocked by unlock service that sent me the unlock code.
I'm not sure what to do iv factory reset the device multiple times and I can't seem to get the phone to switch to Verizon software like the boot screen showing Verizon and all the Verizon apps so I can get wifi calling working.
I tried this before with smooth success with a TMobile note 9 that I got unlocked and installed a Verizon sim card then it immediately prompts me to reboot the device to switch all the new sim card carrier settings and apps.
Hi
I have been able to flash the unlocked non carrier specific firmware on several Verizon Samsung phones over the past few years. Through my employer, I was able to get a free Motorola One 5g UW that I want to take and use on ATT. I know it has the antennas. I can put my sim in, and it shows cricket, but it is locked through Verizon. Is it possible to flash a Motorola from one carrier specific firmware over to another like the Samsungs ? Verizon says it will unlock after 60 days, but even still, it will have Verizon bloatware on it. Thanks in advance.
It doesn't work
Radio in AT&T and VZ versions are different.
Moreover, both bootloader are dead locked and there's NO WAY to unlock
I have a verizon s20 plus that was carrier unlocked by verizon and I want to give it to someone with T-Mobile. If I flash it with T-Mobile or unlocked firmware will that enable lte band 71?

Yes, it should. IF your VZW S20 is already updated to android 11 you'll probably have to downgrade it android 10 , at least I did. To get to TMobile flash Android 10 unlocked on top of the VZW firmware. Let it boot all the way up, insert TMobile SIM, you should get a pop up saying carriers settings need to update or some such, and ask you to reboot. After you've rebooted power off, boot to download mode and flash the TMobile firmware.
You could probably leave it on the unlocked if you wanted. I've just had better signal strength with the TMobile firmware.
