Which is a safe firmware for me? - T-Mobile Samsung Galaxy S7 Questions & Answers

I'm still on Bootloader 2. I can freely flash between G930P PE1, G930V PF2, and G930U PEH.
Would G930T PG1 be a good option? If not, what would you recommend?
T-mobile detected I was rooted and on an unknown firmware (Echoe), and there's several network issues here and if I want their Engineering team to investigate, I need to go back to stock and confirm root doesn't conflict with service.
edit: After further research, it appears the lowest T-mobile bootloader version is 3?

WiFi Calling Firmware EE

Hello there XDA Members,
I have a massive problem and I hope someone in this forum is able to help me, I have an S6 Edge SM-G925F, I recently broke my phone and sent it to repair they repaired it and installed firmware that is non EE therefore I lost my WiFi Calling feature, I was like okay let me just flash the EE firmware unfortunately due to the bootloader they installed being newer then the one from the EE firmware it wont let me install (SW B: 2 K: 4 S: 4) this means that the firmware I am trying to install is older and samsung bootloader wont let me, now I want to know if there is a way I can:
1) Downgrade Bootloader or get it to accept this firmware
2)Have EE WiFI calling another way
3)Install EE WiFi calling onto the phone somehow
My phone is on version 6.0.1

I would say look for a ee firmware that doesn't include the Bootloader. That way the firmware should load, most mm firmwares will run as long as you have a mm bootloader.

SM-G930V purchased in Australia

Hi All,
I have a moderate experience in flashing firmwares and modding my samsung devices over the years.
I have recently purchased an S7 which is unfortunately a SM-G930V model, i thought it would have been the SM0G930F which would have made life much easier.
I want to know if it is possible to get the original Australian firmware or even generic stock firmware on this device?
My issue is with the network settings where i have manually put in APN settings my match my carrier and 4G coverage in australia.
If not am i able to just flash a different baseband to this device preferably Australian?
I have read that flashing a different model firmware will soft brick the device, i just want some insight before i start breaking things, also what are my options.
Much appreciated, thanks, Will
You have the snapdragon s7, you can't flash the exynos 930f firmware on it, you can only flash the american firmware. You might have luck with the 930u unbranded firmware just do some research on it.
Thanks mate,
I'm going to flash this firmware using ODIN, do you know if it will be successful?
https://forum.xda-developers.com/att-galaxy-s7/how-to/xda-community-love-g930u-t3415875
not sure how to check my bootloader version etc
No clue, goto the verizon subforum and see if anyone flashed the 930u firmware on their 930v.
Just tried to flash the firmware to my phone and recieved an error, the phone is now stuck at download mode with error:
sw rev check fail : [system] fused 3 > binary 4
this means the bootloader won't accept the firmware?
LOL, guess ill try another firmware.. Any ideas?

Unlocked Sprint Note 5 new firmware help

Ok, so my question ha a few points here. I have been flashing roms for many years but never really though of this until recently as I now have an unlocked phone.
1. As my Sprint Note 5 is unlocked, can I flash say the Unlocked Version of software to the phone taking away carrier branding? I manage a store from another carrier and I hate that when I boot my phone it shows Sprint. I know it will not trip knox as long as it is Official Stock software.
2. If I do flash said Unlocked version software replacing Sprint software, will it change my connection at all? I have seen that flashing ATT software on a Verizon device did manage to improve ATT tower connection however I wonder if this is maybe a placebo effect as opposed to actually changing the bands and connections the device makes.
If you guys could help me out that would be great. :good:
Cheers
There is no unbranded firmware for the Sprint model because well, it is a exclusive model so even if you flash XAS instead of SPR firmware some or all apps will still appear. The only way to get rid of everything Sprint is via custom ROM= tripped KNOX. The SM-N920P cannot run another firmware.

What happens if unlocked phone is upgraded via Odin?

I have an unlocked phone on Marshmallow.
Will it become locked again if I upgrade it to Nougat using Odin and the official firmware?

Thank you for the firmware source.
Just to clarify, you flashed only that AP, no additional modem or bootloader files?
In addition, is T-mobile a cell phone provider also in Arab emirates? I did some search in internet and it seems the answer is no.
Would it be possible somehow to compare if your phone and mine have been unlocked the same way?
Thank you for any additional help

No my service provider is Etisalat not Tmobile but i bought this phone on Craigslist and it was locked on Tmobile network so the owner sold me very very cheap he didn't know how to unlock it.
I bought it in 140$ and and it's brand new condition almost untouched.
i used a software in windows pc called "Z3X samsung tool pro v29.2" a cracked version to be honest to unlock this phone permanently.
After that i flashed nougat via odin just in AP tab and still unlocked.
I did not flash modem or bootloader separately because this firmware comes in full package Bootloader+Modem+CSC+System all you have to do is use AP tab and upload firmware then flash it.but remember you have to do factory reset from stock recovery immediately after flashing successfully otherwise it can get bootloop
Even though i try Tmobile sim unlock app that comes pre installed but it didn't worked cuz i don't have Tmobile sim card.
I am not sure your phone situation to be honest but since its UNLOCKED already so give it a nougat shot.

Should I flash my Galaxy S7 Verizon to stock firmware in West Africa?

Hello.
I have a Galaxy S7 that I got about 5 weeks ago. I paid to have it in the box but the person got a secondhand one. I am in West Africa but someway somehow I got a Verizon one that is unlocked for any carrier. Anyway I checked and some functions were not working. Private mode is not working, there's no software update option anywhere (I checked developer mode) and some features I've seen on YouTube are not even on the phone. I'm stuck on Android 6 and can't update so I made up my mind to flash a custom ROM but turns out Verizon's bootloader is locked which will make such a task impossible. Some days ago though, I found out that official Verizon ROMs can be flashed without unlocking the bootloader and this raised some questions which I want to ask here.
Here's the info at the about phone page
MODEL NUMBER - SM-G930V (there's Verizon on the back of the phone so I think this is true)
ANDROID VERSION - 6.0.1
BASEBAND VERSION - G930VVRU4API3
BUILD NUMBER - MMB29M.G930VVRU4API3
1. Can I really flash a stock Verizon ROM for the Galaxy S7 without bricking my phone and with a locked bootloader?
2. If I were to flash a stock Verizon ROM will the phone be locked to Verizon again? I'm asking this because this is the only phone I have and I'm supposed to use this for 2 years!
3. Should I flash the same baseband version or will another Verizon one work?
4. If all the above questions are true, where can I get official Verizon stock ROM for my device?
If you have any questions for me please let me know.
Thanks

Yes, you can flash Verizon stock firmware without issues, as long as you are not trying to flash an older Verizon stock firmware than the version you already have. In other words, you can upgrade, but you can't downgrade.
As for flashing a west African firmware, Nn, Verizon devices have a locked bootloader, the locked bootloader will not allow you flash anything except Verizon stock firmware. Attempting to flash anything from another region or from a different device will only result in a soft-bricked or hard-bricked device. You can only flash the Verizon stock firmware for your specific model number.
