Bought unlocked phone and having problems with Spay and data - T-Mobile Samsung Galaxy S8+ Questions & Answers

Recently bought an s8+ and I can't get samsung pay to work. I am in the USA and have the model G955FD. I downloaded Spay off of google play and each time I try and start it, it says cannot connect to server. Anyway to get this to work?
I just added the sim to the phone and it works, but according to some guide I read on here it isn't fully working with tmobile. i.imgur.com/nw9IZbm.png
What firmware do I flash to the phone and is there a guide? Also will flashing the phone lead to more problems, such as permanently disabling samsung pay?
Do I have to flash TMobile software or some other software? Thanks

Unable to use Unlocked Sprint Phone with T-Mobile

Hello,
I have called Sprint many times, after they keep telling me it is unlocked domestically and internationally, I finally gave up. The phone simply says to contact sprint to unlock. I have no idea what to do. When I press UCCI Unlock it gives me an internal error(407). I tried flashing unlocked firmware (U1) But it does not work on that either. Tried booting up with T-Mobile sim inside, still same result. What to do?
Please help!
I had the same problem. I did a factory reset of my phone, and afterwards, the phone was automatically unlocked. For me, it seemed like a firmware bug.
Hi all. After the phone get unlocked, flash the U1 firmware and you'll be just fine. On the U1 firmware, T-Mobile is the only US carrier network that utilize the full potential of the U1 firmware, Wi-Fi calling and VoLTE. Verizon second with VoLTE, Sprint and AT&T no ? good on U1 firmware, only standard U firmware. Happy flashing

What firmware is certified by Google?

Hello to all!
Recently, I ran into a problem: Google Pay does not work, because my currently firmware isn't certified by Google.
I have G710PM (Spint) and I used ULM firmware without carrier bloatware (I used this firmware before, but 2 or 3 days ago, payment stopped working).
The simplest solution that I found on the Internet is to flashVerizon firmware (for example G710VM20b_01_0607.kdz). Oh, a miracle, the device is certified in the Paly Store and Google Pay works But in Verizon firmware there are a lot of carrier garbage that is not needed for me
What other firmware come with certification?
Just uninstall your carrier garbage through ADB shell with the PM uninstall method.

Sm-g975u need help switching att to tmobile

sm-g975u unlocked att phone wanting to change to tmobile. I have a tmobile sim and had originally plugged this in. The phone works fine but I recently noticed it has no Ota updates occurring. I would like to load tmobile firmware on it to enable some of the tmobile features as well but primary concern is ota updates.
the service provider sw ver.
SAOMC_SM-G975U-OYN-AT-PP-0033
ATT/ATT/ATT
BUILD NUMBER
PPR1.180610.011.G975USQS1ASD9
Ap/CP:G975USQS1ASD9
Csc:G975UOYN1ASD9
Last update may 2019
When I try says fully updated when I put it on samsung switch it says fully updated
Can this be done?
What firmware do you suggest?
Csc *#272imei#(may have that wrong) but is recognized and does work not sure when and what to use here, many options.
Also, not sure of the answer here, but if I run an update or csc change (the phone is unlocked) would it require me to unlock it again for any reason?
I am trying to get the phone close to a tmobile if that is possible
Thank you in advance if i need to give more info please let me know.
Download the firmware of your current network and flash you will begin to receive updates. However you can also flash the unbranded one which is G975U1 and you will still receive updates too
Can you give directions on how to get the firmware for the current network and how to flash the phone? I have an SM-G975U that is on SPR that I need to get to ATT so it will get updates from cricket. I have found a lot of materials on the internet and not a single one shows all of the steps clear enough for me to risk blowing up my phone. I have found the SPR files and TMK, and USA, and TMB, but no ATT.

Help Flashing Samsung Galaxy S10+ from VZW to Strait-Talk

Hey everyone,
I'm new to flashing phones but have experience flashing other hardware; still, I felt it prudent to ask for some guidance on this being my first attempt:
I have a Straight-Talk phone which is active and working with 4G that I would like to swap the SIM over to use in my Galaxy S10+ from Verizon.
Swapping the SIM without flashing limited the functionality to be contingent on WiFi; 4G would not work correctly.
So I suspect I'll need to flash with unlocked firmware to get it to work properly.
I have downloaded the G975U1_SAU_1.zip which is what I think I'll be needing to pull this off, as well as the latest available download of Odin (3.14.1).
Before I get started, I'd just like to ask some Questions:
Should I leave the intended SIM (Straight-Talk) in the S10+ (Verizon) while I'm flashing, or insert it after the flashing?
Am I using the correct firmware to flash this Verizon phone to work with Strait-Talk? (United States regions)
Also should I back up the intended SIM in some fashion before proceeding with this process (if so what software if any would be advisable for this?)
Is there anything I need to watch out for?
Am I on the right track for what I'm attempting to do?
Thanks in advanced for any help! :highfive:

Insert SIM after flashing. You need the current U1 firmware from sam mobile. You also need the patched version of Odin that's floating around the forums here. No need to backup your SIM, but using Odin will reset your phone to brand new. Nothing that I can think of, you just put the correct Odin file in each slot and hit go. Seems like you're onto it, you need 3 things which are patched Odin, latest firmware, and I think phone drivers so your PC recognizes the phone. Should be able to find these on Samsung website or other parts of the web.
Thanks for the support!
After your encouragement, I rechecked my firmware made sure to acquire the USB Drivers from Samsung.
Successfully flashed the phone and its now working as intended!
:victory:
I used the Frija tool mentioned here to make sure I had the right files.
And the Driver install came from here.
Thanks again for your support! :highfive:

No problem man, glad to help. Good you posted links too so others can do the same if they're having issues.
Absolutely!
Anything I can do to help pay it forward.
I should also mention I got my CSC code from the list posted at
Droid Views dot com /how-to-change-csc-in-samsung-galaxy-phones/
(Won't let me post the outside link given that I'm new)
The code was required to use Frija to download the correct firmware.
(The 4GB download averaged at 2.5MB/s)
Here is the list I saw on the aforementioned page; I used XAA
Code:
[LIST]
[*]ACG – Nextech/C Spire
[*]ATT – AT&T
[*]CCT – Comcast
[*]LRA – Bluegrass Cellular
[*]SPR – Sprint (CDMA)
[*]TFN – Tracfone
[*]TMB – T-Mobile
[*]USC – US Cellular
[*]VMU – Virgin Mobile USA
[*]VZW – Verizon
[*]XAA – USA (unbranded/unlocked/default)
[*]XAS – USA (unbranded/unlocked)
[/LIST]
Random questions:
If you start with a Tmobile GM-S975U that is carrier unlocked (got unlock code from tmobile)
Will it work just fine with straight talk? If not Does changing the CSC code work, and to which code?
Is different firmware required? like U1?

The U1 software for the S-10 plus is strait from Samsung and has no carrier bloat. All US S-10 pluses are the same, no matter who the carrier is. That means you can flash any vendors rom as long as you don't go backwards on the bootloader version. The phone gets set up by the simm card installed on the first boot. The good things about the U1 software is there is no vendor bloat and your updates come straight from Samsung. Don't forget, you have to us the customized Odin to flash with.
Deatailed info and Odin link can be found here. https://forum.xda-developers.com/s10-plus/how-to/guide-g975f-flashing-megathread-faqs-t3936704
Thanks for the reply. Should straight talk just work? My friend says data isn’t working on tmo firmware. What firmware and Csc code would work with them?
curious, do mobile Hotspot work, or is carrier still able to block it?

CSC Change On Locked VZW S9 To Use It On Tracfone?

Good day everyone!
I recently got a new phone (Galaxy S21), and I saw that you can bring your own phone to Tracfone, so I gave my Verizon S9 (SM-G960U) to my wife (to upgrade her old Samsung Tracfone phone).
We bought and installed the Tracfone SIM card and everything seemed to be working (she could make and take phone calls).
Little did I realize that Tracfone actually also uses WiFi for phone calls, and thus making and taking calls was not using Tracfone's network while connected to WiFi.
When we started researching why her phone did not work outside the home, we found that the CSC is still set to VZW.
This S9 has the latest April 2021 security update from Verizon (Android 10).
I downloaded an older stock Tracfone ROM, but Odin fails with an Auth error (presumably because the phone is not unlocked nor rooted, and the bootloader is locked).
I also tried just flashing the CSC with a Tracfone CSC, but it also failed with an Auth error.
All of the research I have done to this point indicates that Samsung makes flashing Android 10 Galaxy phones very difficult, and I suspect that I am screwed.
Should I put the Verizon SIM card back in and beg Verizon support for an unlock code? Will that even help?
Why doesn't the Tracfone SIM card override the VZW CSC? I thought the SIM card would take precedence.
Thank you in advance, and I hope I am not repeating another thread (I searched, but I couldn't find anything related to changing CSC or rooting a Samsung Galaxy phone running Android 10).
P.S. I have no objections to performing a factory reset of the phone if it will help.
P.P.S. I would like to run the stock Tracfone S9 image so my wife can get the OTA updates, but I'm willing to do whatever to get it working (I would even be happy with running the existing VZW firmware as long as it works).
