Can I switch carrier firmware?

My phone is on G928VVRU2BPD4. It's a Verizon carrier unlocked phone I currently use it with AT&T I'm on marshmallow 6.0.1. Since I use it on AT&T I cannot get any Ota updates I have to use odin. My question is can I switch it to AT&T firmware? Also is the AT&T version root able if I am able to switch it?
Unfortunately no.If y had an....lets say g928f carrier locked then yes switching is easy but since you have an g928v (the v at the end stands for verizon) you cannot change to another firmware since its a verizon model and there are no other firmwares for it.

AT&T Branded Note 4 (Unlocked) on T-Mobile -- firmware flash?

I recently activated my SM-N910A on my new T-Mobile account. The phone was out of contract, so I asked AT&T to unlock it, and they did. The phone is working properly with my T-Mobile SIM card, albeit on the AT&T firmware.
Is it possible to replace the AT&T firmware with a stock Samsung Firmware, or, at the very least, with the T-Mobile branded firmware (for SM-N910T)? I understand that the bootloader is locked on these AT&T devices. Is it possible to unlock the bootloader and load a different firmware onto the device?
AT&T firmware has SO much bloatware, and I've not had any luck finding a way to root the phone on this firmware, so I'm stuck with all that bloat. What are my options here? Thanks!
EDIT: The phone was updated OTA to Marshmallow (6.0.1) when it was on the AT&T network. Build number is MMB29M.N910AUCS2EPH7

Change Device Model/Type

I installed the USA unlocked firmware (G935U) on my AT&T S7 Edge (G935A) but my company flagged it as an unsupported device when connecting to the Exchange Server (total BS since it's the same phone). Anyway, I had to go back to the AT&T firmware but it's killing in terms of how slow and buggy it is.
If I go back to the G935U, does anyone know if it's possible to change the device model/type so it matches the AT&T device ID? Basically go from SM-G935U to SAMSUNG-SM-G935A.
You need to download unlocked firmware but with same version. In most situactions you cant install G935A on G935U.
Download firmware from here and try to flash it https://www.sammobile.com/firmwares/database/SM-G935U/

G950F model with T-Mobile US

Hello is there a way to flash the T-Mobile (G950U) firmware onto a G950F model phone or change the CSC without root? While the phone is working, I do not believe it is able to take advantage of carrier aggregation and VoLTE without the proper region code for my area. Wondering if there is any way to achieve this? Thank you.
You want to flash snapdragon firmware on an exynos phone? You sure?
I'd like to know this too...
so is this not possible??
Guess I went the wrong route by purchasing an unlocked phone to use on the Tmobile network. the internet is sooooo slow...

AT&T Galaxy S8 software update

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
