Can the verizon variant be fully converted to unlocked version?

Hello. I have been on the forum for days searching for answers for the sprint variant, which is hard to find solid proof of it working completely on gsm. Now for the verizon variant. If I buy a verizon variant will it work fully on GSM carriers like at&t?
Plus can it be fully converted? Including radio, to the US unlocked version? I have done it in the past with the at&t m8, converting it to unlocked variant with s-off, cid change, and ruu. I see tutorials saying to flash unlocked version to then reflash verizon radio. Will it work with unlocked radio? Or is it the same as with the sprint variant, where it always needs sprint radio?
Thanks for any help.

Thanks. I had read that forum, but since the guide posted says to flash verizon radio, I was wondering if you could leave the unlocked radio. After reading various posts afterwards it seems it is posible to not flash the verizon radio (keep the unlocked radio).

Correct, you can fully convert to Unlocked without flashing anything Verizon afterwards. Im using my Vzw 10 on a gsm network, converted to unlocked.

Thanks. I will look into buying the verizon variant. Did you also have to sim unlock? Or will flashing the unlocked version ruu take care of that? I truely doubt it, but I can not find any verizon unlocking service. And the only 10's I can find are locked to verizon.

Verizon 10 is not sim locked. You can take it, in stock Verizon form, and insert a gsm sim card and it will work. The real benefit of converting to unlocked is to have direct updates, have access to more lte bands, and best of all not have Verizon's bloated OS.

Confused - Unlocked Samsung S8+ from Samsung ... on ATT

I just purchased an unlocked S8+ from Samsung to use on AT&T in the U.S.
Do I need to do anything to the phone to be able to use all of the AT&Ts features/ VoLTE / get OTA updates timely?
Any help is appreciated!

I was not able to get any of the features on AT&T (including voice over lte).
The updates will not be coming from AT&T, they come straight from Samsung.
Basically you bought a phone that can work on AT&T, everything that got to do with the phone is not related to AT&T and not it's responsibility.

I was able to get wifi calling, but not VoLTE. What's your carrier codes? What did you tell Att was your imei?

I got volte when I flashed carrier change but instead of doing the Guide for the T-Mobile I did the AT&T one at the very end And had no need to call AT&T

I'm little confused about between "Carrier switch" and "flash standard firmware" section in the follow post. Basically, not sure what file to use. I just downloaded the latest ATT firmware which includes AP, CP, BL, CSC, USERDATA files. should i just flash all of them using ODIN and use the adb line to "ECHO-> ATT"? is there a specific order i need to follow? thx.

If you have an unlocked Galaxy S8 u1 I followed these instructions from the beginning but instead of flashing the T-Mobile firmware at the end I flashed the AT&T one it works great for me with wifi calling and voice over LTE
https://forum.xda-developers.com/tm.../guide-how-to-convert-to-100-stock-t-t3615957

what i don't understand is they use G950W which is a canadian firmware. I am on US ATT network so i want to use US ATT fireware.

Honestly I don't know why they Flash the Canadian one but I followed all the instructions and at the very end I flash the AT&T one and everything works fine honestly I don't know what's the purpose of flashing the Canadians home

I'm not seeing the att portion in that thread..
and this flashing, does it wipe the phone and you have US att and the 950U1 and it then still worked for the USA att? (giving hd voice)? (need hd voice for s3 watch and numbersync to work apparently)

at&t to verizon

I just picked up a used s7 edge from a at&t customer, every thing that I could find said once unlocked it would work on any network. I unlocked it via at&t, checked that it works on an at&t sim and Tmobile but it is not working on my Verizon sim and their techs can get it to work either.
Will an At&t s7 edge work on a Verizon network? if so how? Or should I find a different phone?
Thanks
Andy

That is an interesting question. I believe all the US based Snapdragon S7 and S7 Edges have the same hardware, so you would just need to flash Verizon or unlocked firmware over the AT&T image. That part is confirmed, as people have gone from V to U and A, and A to U and V. If I were you, I'd probably go for the unbranded firmware, but that's a personal preference.
The real trick is getting Verizon to properly provision it.

At&t is gsm and Verizon is cdma not compatible with cdma you need to give carrier imei that's how cdma works not just with SIM card
Sent from my SAMSUNG-SM-G935A using XDA-Developers Legacy app

The US (Snapdragon) S7 and S7 edge share the same physical hardware. There is a better than average chance that if he flashes the U or V firmware, and can get Verizon to put on their network, it will fly.

Question: to convert from one firmware to another do I have to install U first? I want to convert my G935T to G935A to be able to use wi-fi calling. My phone is unlocked and everything works on At&t except for wi-fi calling (Or VoLte as I see it referred to often)

If this is your first device with AT&T to support WiFi calling, you may have to get a new SIM (or get your current SIM provisioned correctly).

So are you saying I don't need to install the G935A firmware?

Using the AT&T H910 outside of the US. Does that mean I will never get any update?

I heard that an active AT&T sim card is required for software or system update. Is it possible that I buy an AT&T prepaid sim card from ebay and use it solely for system update outside of the US?

Yes. As long as you are on an AT&T network. Roaming on another provider will not work. You have to have an AT&T SIM *AND* be on the AT&T network.
The other very LONG way, is to root your phone, and then flash the latest firmware. If you don't want to stay rooted, then you can flash the latest full stock firmware which will take you back to stock.

I have this issue as well, unlocked AT&T version on Cricket, I bought a GoPhone SIM hoping that just putting it in the phone would work, but it needs to be active.

Okay thanks for your replies. I guess there is nothing more I can do about it then.

If using 900ds on Cricket, will cricket push updates or can one use the att SIM trick? Ty

You need to contact verizon support and make them to explain what is the problem exactly, ask for supervisor if needed. "There is an error" is not an acceptable answer.
Probably they need to whitelist your IMEI somewhere b/c it's not from verizon or unlocked phone originally - I'm just guessing here.

Verizon uses CDMA, Sprint uses CDMA but both of them are on different CDMA network, uses different hardware for it so in your case it wont help.
