I attempted to research these quite a bit but couldn't find answers to these specific questions so I'm hoping someone's able to help me out. I have an unlocked S8+ coming tomorrow that I plan to use on my existing Verizon line. I'm reading about carrier firmware and CSC codes and have a few questions.
1) Am I required to change either the firmware or CSC to use it on Verizon or can I just pop in my (already activated) SIM and be good to go?
2) What are the pros/cons of changing or not changing them to Verizon before setting it up? (ie. bloatware, wifi calling, etc.)
3) Does flashing either change whether I receive OTAs from the carrier or are carrier updates released just for their own branded devices and either way I'd have to wait for Samsung for unlocked updates?
Any help, whether answers or a simple link to an existing answer I somehow didn't find, would be greatly appreciated.
Thanks!

hey there.
so short version.
i got a sprint s7, apparently it was not carrier unlocked when i got it. sprint says they will only unlock it if it's on an active service in good standing which i dont plan on getting on sprint at all. so i need a trusted place to get the unlock codes for it please, the cheaper the better because of my situation.
longer version.
my dad has early onset dementia so we had to take his phone from him and close his account. it's been a while and i found his S7 sitting there not doing anything and i need a new phone to put on my Verizon prepaid plan so after looking on the s7 the hardware is all the same just the firmware blocks out whichever bands each carrier chooses. so i need to go tomorrow and get one of Verizon sims to be ready so when i get the unlock code i can put it in right away and make sure i dont receive that sim error. or do i need to flash to the verizion firmware before i try to carrier unlock it?
any and all help is really appreciated as our family is really struggling atm and not having to purchase a new phone would save us alot of money.
p.s. device info is sm-g930p
baseband g930pvps4bqc1
android version 7
Here's a link to the remote unlocking service I used to have my 930P unlocked: https://www.gsmzambia.com/product/samsung-sprint/
You'll have to install Teamviewer and let them remotely control your PC to perform the unlock. I found them to be very reputable and helpful before, during and after the sale.
After unlocking, I'd recommend using Odin (https://www.androidfilehost.com/?fid=24591023225177749) to flash the "U" firmware: http://updato.com/firmware-archive-select-model?record=52EF42AE925C11E7963AFA163EE8F90B
With U firmware, you won't have any of the Sprint bloatware that came preloaded on the phone, and it'll automatically detect and apply the proper settings for whichever SIM card you insert. If you don't want to flash alternate firmware, you can stick with what's already on the phone; you'll just have to manually enter the Verizon APN settings.
Hello everyone,
I have an unbranded, factory unlocked U1 Samsung Galaxy S8 that I am wanting to switch to Verizon Prepaid. Currently, it's running on Tracfone with the T-Mobile network. Wi-Fi Calling is a must-have for me, but I've heard that it will not work on Verizon with the factory unlocked Galaxy S8 model. It currently works on Tracfone/T-Mobile, though.
Rather than going the extreme route of getting another phone, I was hoping that it would be possible to just flash the Verizon firmware on it in order to gain Wi-Fi Calling and other carrier features from Verizon.
Below are some questions I have about this.
1. Is this likely to work, or would I just be better off to get a branded phone?
2. Is the process as simple as it sounds on the SamMobile site? Or does the process involve something more like this?
3. Will I be able to receive OTA updates after flashing carrier firmware?
4. Are there any particular issues or pitfalls that I should be aware of before attempting this? (besides possible data loss, of course)
5. Will I be able to flash it back 100% to the stock firmware later on if I want to sell it?
6. Is there any other way to get Verizon Wi-Fi Calling while staying on the unlocked firmware?
Any input would be appreciated.
Thanks!
It is to ask i am having an unlocked s8 active with different carrier and out of usa... no ota here i am able to get and stuck on May security patch.. can somone suggest a way to pull updates as site is listing 2 more FOTAs more there.. will greatly thankful
You cant get otas outside of the usa on the phone its impossible. I did however just upload the dec update to the guides thread. You can flash that.

May be, if someone can connect through other's at&t phone in the US through vpn it could be done?

I doubt it, i would assume it needs to connect to att towers, it probably checks the sim too. But truthfully i have no idea, i just highly doubt it. Updating us phones overseas has always been done via odin and sideloading.
can I use this firmware over the AT&T S8 Active?
https://updato.com/firmware-archive-select-model?record=9A769F232AFE11E99F15FA163EE8F90B
for now I'm on G892AUCS3BRG1
i'm asking because that both my existing firmware and new one on Link above are the same 3rd bootloader
New from TMB G892USQS3BSA2
On My AT&T device G892AUCS3BRG1
in both fifth symbol from the right to left are (3)

You're looking at the SM-G892U model. OP has the 892A. I wouldn't flash that unless you know they're interchangeable and also want a bunch of tmobile apps on the phone.
I've tried but even patched odin couldn't flash
Noob here. Checked forums for answers, but getting confused.
Just bought an S8, model SM-G950FD, which appears as though it's from UAE. I'd like to avail myself of VoLTE and WiFi calling on my main SIM (these features aren't important to me on my secondary SIM). CSC on phone is OXM_XSG.
1. Is it possible to flash my phone with a Canadian CSC even though my processor is Exynos?
2. If yes, where do I get the appropriate file to flash?
3. Can somebody spoon-feed this old guy on how to do this? I already downloaded Odin, but I want to hear from some more experienced folks so that I don't brick my phone.
4. Lastly, my main SIM is Canadian but my second SIM is from Europe. If I change my CSC to a Canadian carrier, will this affect the operation of my European SIM?
Thanks for sharing your experience.
I have an old Tmobile S7E on old ass firmware (Android 7.0 BQE1) and it's already rooted. I just went through Tmobiles Device Unlock process and I believe the phone was unlocked successfully. I'm looking to upgrade to the latest firmware that still allows rooting. I've looked through the Custom Roms threads and can't tell which one is the latest. I am also wondering if I need to use Verizon firmware or stay on Tmobile firmware.
For instance, this thread here: by jrkruse, he mentions to another user in the comments "This one or verizon one? This one just has the Tmobile csc stuff added and a build.prop for gsm carriers thats it" so it made me wonder if I'm using Verizon service but it's a Tmobile phone if this would work. I know Verizon is CDMA so him saying gsm carriers made me think it may not work.
I know this device is old and this thread doesn't get browsed as much anymore so hopefully I can get some answers. If I can't get this working I guess I'll just be getting a new 2020 model phone :highfive:
Thanks guys!
