Hey! I have an unlocked S7 from T-Mobile. What all would I need to do to get it working with Verizon? Would Flashing Verizon firmware onto it (I actually already did this once for the Nougat Beta) make the CDMA radios work?

Yes you can flash the Verizon firmware or the 930u firmware and it will work on Verizon. There is no 930u Nougat firmware yet though.

T-mobile I'm looking to leave verizon I know that the Verizon variant does not have 2 of the lte bands that T-mobile uses can I use Odin to Flash the 935t firmware to get the band's or am I asking something that is not possible. Thanks in advance

The answer is NO you're asking firmware to replace/add hardware and that's not possible
I have a Verizon branded s7 edge and used Odin to load the 935U PI3 firmware. I am on T-Mo now and do have LTE band 12 working (validated with LTE Discovery). The research that I did found that the US variants have all the radios in them, but some carrier variants of firmware disable certain bands. By doing the 935U firmware, I also got rid of the notice on every reboot that I was using a non-Verizon SIM. So I now have all T-mo bands and no stupid SIM message.

I can vouch for same experience as SF-IT guy. I bought a G935V and flashed with G935U firmware via odin. Works on T-mobile, even wifi calling works. Currently on the latest PI3 version of G935U firmware. I would that you search the forum to see if you can flash the G935T firmware directly. The only downside of using G935U firmware is that the FM radio chip is not enabled in the firmware. I read that the all the carrier versions (September security patch and newer) of the G935 firmware have the FM radio chip enabled. I prefer the 935U version because it there is not carrier bloatware. Samsung bloatware is still there.

So what would the FM radio chip do? Just enable FM radios is all? Because if that's the downside then it's not a major setback as not too many people use the FM radio.
I don't think you can

You definitely can. All US versions of the S7 & S7 Edge are the same hardware and can be flashed to any other US firmware. (including the U firmware that automatically works on all 4 carriers)

So what you're saying is that flashing the U version firmware will unlock by default all 930"X" and 935"X" phones? As in it just unlocks the mofo and debloats some while you're at it?
What's the catch? It seems too easy

Bloat is definitely gone on the U firmware, which is great. My phone runs faster and has more free space too.
I think some carrier features aren't supported on the U firmware. On T-mobile everything works (VoLTE and Wi-Fi Calling), but I think AT&T might have some issues with those.
If the phone is SIM locked to a particular carrier, I'm not sure that automatically gets turned off or not when you switch to the U firmware. You might need to contact your carrier first to get an unlock code?

What if I got a temporary unlock from t-mobile unlock app and then flashed this firmware? Would it make it permanent? Seems quite possible, but I don't know if the temporary unlock actually unlocks the phone or just inserts a bypass that would disappear if flashed.

I unlocked my US TMo phone when stock, rooted, and am running Echoe - which has a glitch where WiFi calling sort of works (can receive calls but not make them). In the TMo forum, there are threads on U - your comments here are more specific to what I am interested.
Which U firmware are you on and are you rooted (is is updated to latest v4 bootloader version), and did you have to ODIN and full wipe with CSC or did you get by with CSC Home to preserve data?
Also, are you on U CP or did you flash TMo CP to get all the bands?.

Thanks everyone
I apologize, I tried searching for this, but I couldnt find the answer.
Out of curiosity... if I flash my AT&T S7 Edge with the Verizon stock Rom, will that unlock all the necessary bands needed to support a Verizon simcard?
No, the AT&T S7 is missing the CDMA bands that require to run on Verizon. You would have to get either the 930V or 930U variants.

It will unlock the Verizon bands, I can personally confirm this. CDMA part gets activated too. All US S7s have the CDMA portion, its the firmware that enables or disables CDMA. For example, if you flash the T-Mobile/AT&T firmware on a Verizon or Sprint S7, the CDMA is disabled by the firmware and if you flashed the Verizon/Sprint firmware on an AT&T/T-Mobile S7, the CDMA portion is enabled by the firmware. The US unbranded Firmware has the GSM/CDMA portions enabled by default.

I went from 930a to 930v, it works fine firmware wise but is constantly roaming. Do you have this issue?

Not sure to be honest, my carrier is gsm only so i dont use the verizon firmware on mines.
Hi,
I'm a little confused here. I want to upgrade my firmware on an unlocked S8 I bought SM-G950U and it's currently running G950USQS2BQL1 which is VZW FW but I have att as a provider.
To update my firmware do I flash VZW FW or can I flash ATT FW? If I'm able to flash ATT will updates be pushed OTC from now on? Also is there a way to upgrade without wiping the data? Lastly, can I update straight to Oreo (one again without losing data?) The OTA function never provides any updates.
Thanks.

Flash the US XAA firmware and you will get rid of all the carrier bloat and get updates straight from Samsung servers.
If the S8 is unlocked then you can just pop in the Verizon sim and it'll ask to reboot and then you'll have the ATT FW.

Okay, so I need a Verizon SIM to update the device?

What month security patch are you on? If its the November or later it should switch to an ATT S8 after it asks you to reboot. If its earlier then yea you'll be a verizon(doesn't have to be active) sim to get it to take the OTAs to being you speed, and then it'll change to an ATT S8 after asking for a reboot.
Edit: You don't have to flash a different carrier version, it'll change itself on the newer FWs to match whatever sim is in the phone.
I have a question. I have the Unlocked AT&T Samsung Galaxy S8 (didn't realise it was AT&T until I received it and turned it on) and when I go to update the software it says it is up to date but it is not. How do I update my software? I am not rooted or anything, the phone is in its normal state.
Is it an unlocked S8 with AT&T firmware or an unlocked AT&T S8? Also, what carrier are you using?
Either way, you can use Odin to flash the newest firmware. Search Updato.com for the firmware for G950U (AT&T variant if you want bloat) or for the G950U1 if you want actual unlocked firmware with no bloat. However, the newest that they have posted if CRF5 and CG3 just came out the other day.
I asked about carrier because:
If you're running on Tmobile for example, use the tmobile firmware. You'll have bloat but you'll get all the features and you'll be good to go on updates.
If you're using Tmobile and want Unlocked firmware download the TMO coded U1 firmware and again, you'll be good with updates.
@jpcdeux I would think it has AT&T firmware because it came with a few AT&T apps on it. However, it is not locked to at&t so I am able to use it in my country (St. Kitts).
Would I have to root?
No, rooting is not required to flash unlocked firmware
Thanks much @jpcdeux
I have a Sprint Galaxy s8, but I am no longer on Sprint.
Is it possible for me to flash the unlocked ROM, effectively making it SM-G950U1?
My current build nnumber: R16NW.G950USQU5CSA4
I'm hoping when it's available I can flash to the Pie version of G950U1.

Only if Sprint unlocked the device through uicc unlock. If you flash u1 on a locked it's still stuck to the original carrier. As for guides there are several guides in the general section for carrier switching

Yes it is. I just did it yesterday. I was on G950USQS5CSB1 and didn't get wifi calling or VoLTE on Mint Mobile but after flashing G950U1 I now have them.
Since you say you are no longer on Sprint I assume you just want the unbranded G950U1 firmware.
Using samfirm on your computer putin G950U1 as phone and XAA as CSC and search. You should get G950U1UES5CSB2. It is the latest and has the same bootloader as you. Download it.
Download and use the 3B modded version of Odin.
Back up your phone as it will be wiped.
study here how to use Odin..... there are many guides
Use the CSC file not Home_CSC.
Have the sim of your current carrier in the phone when you flash.

This is exactly what I'm doing. Switched to Mint, but don't heav Wifi or VoLTE. Glad to hear that G950U1 works with both those (was worried I would have to flash TMO to get it).
Thanks again!
