Flashing Unlocked or AT&T firmware on unlocked Sprint S7? - Samsung Galaxy S7 Questions and Answers

Hello, I'm selling my old Galaxy S7 to a friend of mine and he plans on using Straight Talk or any GSM compatible pre-paid network. Using Straight Talk on an unlocked Galaxy S7 wasn't the best experience for me since I'd have issues reconnecting to cellular data and reliability was shaky compared to non-Sprint branded phones.
Someone suggested to flash either AT&T or unlocked firmware on my S7, but I'm not sure if it's safe to do. If so, what it is the most stable firmware?
EDIT: I tried flashing the unlocked firmware and Odin failed. Using v3.13. also got a rev check fail: fused 8 > binary 4
EDIT 2: Downloaded a newer version of the unlocked firmware, was able to flash successfully

Possible to flash unlocked Samsung Galaxy S6 G920A (AT&T) to G920T (T-Mobile)?

I own an unlocked Samsung G920A which I actually flashed to a G920AZ (Cricket Wireless (who is owned by AT&T)). I now want to flash to T-Mobile as I want to be able to 1. get Marshmallow. Cricket may never. 2. Be able to use WiFi calling and you can only do that with the TMO image (from what I read). I downloaded the G920TUVU3EPD1_G920TTMB3EPD1_G920TUVU3EPD1_HOME.tar and using Odin tried, but it fails.
Is it possible to flash to the T-Mobile firmware/ROM ?
If it is impossible, then I think I would want to go to the G920A again to get Marshmallow 6.0.1, then simply pop the T-Mobile SIM in, update APN, etc. Unfortunate though as the LTE bands all work. Seems sh***y it wouldn't work to use their firmware.

Suggest an international rom for an Unlocked N915T

Hi folks,
I have an American T-mobile factory unlocked Galaxy note edge (SM-N915T) that I use in the UK on Three's network.
I would like to flash an official unlocked international ROM, preferably with a Marshmallow, so I get faster updates (Tmobile is very slow at this) plus no additional Tmobile's widgets and apps.
Any suggestions? I tried flashing a BTU region N915FYXXU1DPC3 via odin but got an error, I imagine it is not compatible with my phone?

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?

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?

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.

Thank you very much!
