G930V ROMs? - Samsung Galaxy S7 Questions and Answers

So now that I'm running a rooted S7 on Verizon (G930V), I'm looking into custom ROMs. Everything I can find seems to be for other variants. Is there anything for the G930V? I can't seem to figure out how to tell when most of the ROM's don't specify.

In the forums for the G935V they only have the firmware from the G935U, plus some minor changes to the U's firmware to allow Wi-Fi calling, etc. on Verizon's network.
I would assume that you could do the same, but make sure you only use the G930 and not G935's firmware. That's all that really exists at this time because the bootloaders are still locked and I'm not sure if there is a working method of TWRP around for the S7/E variants in the US.

[Q] S6 variants - which firmware/modem/bootloader is interchangeable?

I'm not as concerned about this for ROM flashing. I'm wanting to find out if my G920T can use G920I or G920F modems/bootloaders, etc.
Here's my deal. I have a T-Mobile G920T. To unlock this phone I need to get away from the G920T modem. I previously had a G920T1 (MetroPCS) firmware set installed and it worked great, but the rom sucked.
I've since restored back to stock G920T and i've rooted/twrp, but I see other ROM's and I'd like to give them a shot. The catch - they all say I need to have the newest OI7 firmware installed. I'm still on the G920T sim locked OH8. The only OI7 modems/bootloaders I can find are for the G920F variant. I can't find OI7 for the G920T1 variant. I don't know if the G920F variant will sim unlock my phone. I don't want to brick my phone to figure that out, so this is the reason why I posted this question. I can flash ROM's all day long, but if I can't use my Cricket sim when I'm out in BFE then the ROM is pointless.
Does anyone understand what I'm asking?

DO NOT flash any FIrmewares through odin if its isn't your model number, if you purchased your phone and don't have an EIP you could sim unlock with the app, so any rom your on unless its not Touch wiz based (aren't any available besides touchwiz)

Flashing G930A ROM?

Currently have a G930T on ATT sim thats rooted and all (bought it because I though it would have an unlocked bootloader lol). I wanted to flash this G930A rom http://forum.xda-developers.com/att...30apf2stockdeodexeddebloatedrom-7-12-t3417012 because I wanted the AT&T wi-fi calling and video calling to work.... I've seen in another thread that the firmware between G930T and G930U has different bootloaders currently? Is this the case between the bootloaders of the G930T and the G930A as well? Also, does anybody know how I can find which bootloader I currently have?
Thanks.

New to S7 - Few Questions

I just ordered the S7 G930U, coming from S4, as I understood that it has support for more frequencies and I wanted the ability to switch between Verizon and T-mobile without a problem. I have a few questions:
Did I understand this correct, or it's based on the firmware? So If I get the G930V phone and flash the G930T firmware, would that use/open all the frequencies on the T-mobile, or the phone has hardware limitations?
I have been reading around, and I got that if I use the G930U on Verizon, I will lose the Wifi-calling and some other options, if I flash the G930V firmware on my G930U phone, would that make them work or not? Is there any way to make those options work on the G930U without changing the firmware?
I see different sub-forums for Verizon, T-Mobile, etc. How about the unlocked G930U? I don't fully understand this. Do I just use the G930V Roms on my G930U if I am using it with Verizon? Can I flash any ROM on my G930U, as it's unlocked, or I am not understanding this right?
If I flash a different Firmware, would that trip Knox/warranty?

You can flash Verizon's firmware without tripping Knox if you follow the directions posted on the forums and you will have wifi calling and all other Verizon features. You must flash Verizon's software for those features to work. I'm not sure if you can flash any ROM, and I'm also not sure if you can flash T-Mobile firmware but I don't see why it wouldn't work, make sure to go to T-Mobile's sub forum and read up on it
Thanks Outbreak444. I read in XDA that the hardware is the same for G920U, G930T or G930V, it's just the firmware and you can install it, is that true? The reason I am asking is that the price changes between them.
Can someone that has the G930U confirm that you can flash different Roms on it?

Yes, by doing a quick search I see others talking about flashing their U phones with the T's firmware and no problems arising. Make sure to read up on how to do it, download the files you need, read again and make sure you understand everything. If you don't understand a step then ask before moving forward, it will prevent headaches. If you feel good about what you need to do then follow through with it, you shouldn't have any problems and will find it's quite simple. But flashing between multiple firmwares will most likely wipe your phone every time. I could be wrong, I know I've read certain CSC files won't do that but I'm not sure if that's just from rooted or not.

Have S7Active and moved to T-Mobile ... What's to do?

I was able to save a ton on my monthy bill by moving from AT&T to T-mobile.
The rest of the family all had iPhones so the move was relatively smooth for them.
I have a Samsung S7 Active (G891A). I have been able to get it to work on T-Mobile network,
However, there are still tons of AT&T only settings and apps and stuff still hanging around.
I am looking for advice as to what to do ...
Live with it?
Use a custom ROM? If so which?
What are ramifications of custom ROM (the phone is obviously unlocked)?
Thanks
If the active has an unlocked variant, you could flash the unlocked firmware via Odin which has no bloat.
Custom ROM's won't be an option if it's a Snapdragon/Qualcomm SoC since they have locked bootloaders.
I was only able to find S8 active firmware from the usual sites (updato & sammobile) but there was an S8 unlocked variant so there has to be an S7 unlocked variant.

G930W8 on T-mobile, and did I get lucky?

I just bought a used S7. I was told it was the Sprint version, but when I checked it it turned out to be a Rogers 930W8 with an Exynos 8890 which is a little faster than the S820 in my other phone.
Did I actually get lucky with this version or would the Sprint be better?
I would like to have it fully functional on Tmobile including all bands such as LTE band 12 and VoLTE and Wifi calling.
With Sprint the plan was to flash the stock Tmobile firmware.
Is that still an option with with the Exynox?
Do I even need full firmware and would flashing just CSC files to get me VoLTE and wifi calling.
Also, is the bootloader unlocked on all Exynos phones, and if so, is there an even better option than Tmobile firmware to give me everything I want?
Thanks
Flashing T-Mobile firmware won't be possible because it's developed the snapdragon SoC specifically, you'd brick the phone trying to flash it onto exynos, assuming Odin would even let you flash it at all.
Same goes for the CSC, you will need it for VoLTE and VoWIFI but you'd brick it trying to flash via Odin. Your best bet would probably be flashing TWRP and flashing the CSC zip if it's still being updated.
