Other carrier flashfire roms on the g935a - AT&T Samsung Galaxy S7 Edge Questions & Answers

Just wondering if one could use, say, g935u flashfire roms on the g935a if they don't include a custom kernel now that we have root? If so, that opens up a whole realm of possibilities.
I get the feeling I may be off on either how flashfire works, or how limited we are one what the g935a can do with the locked bootloader.

All things root and Bootloader?

Hi Friends,
Hope you're all having a great new year. So last time I was lurking the S7E forums, we had a leaked Engineering Bootloader that was used to acquire root on all US Snapdragon models, albeit, with a lot performance issues and etc.
I came here to glance as well as all other variant forums for the SD model and now we have Root for every model, with even ROMs being baked like the Echo ROM for Verizon, Sprint, AT&T models, usually the toughest to achieve these things on. I'm trying to read through the forums, but I fear I'm missing the details, that will help me pull the trigger for getting the device or not.
Can one of you very experienced, knowledgeable, and kind members educate me on the latest?
1. Do we have unlocked Bootloader and Root for all US carrier S7Es? How is it done? I use people using Flashfire. So no TWRP?
2. Does this process still trip Knox and render Samsung Pay to never be used again on the device?
3. If I bought the Verizon variant, for example, can I root, unlock Bootloader, and etc, and then return to stock, to return to the store in case I don't like the phone?
4. Xposed Framework working for all models?
Much appreciate your responses, any and all of them in advance! Thanks!
1. No public unlocked Bootloader on any US variant. Flashfire works but no custom recovery
2. Right now with eng Kernel and custom(ish) roms like Echo don't trip Knox since it is still the U firmware of the s7
3. You can root and jump to roms like echo or other stockish roms and return to normal and return to store but no unlocked bootloader
4. Far as I know Xposed works on most if not all (I have mine on and Att variant running Echo) It is installed/Flashed via Flashfire and is a custom version.
Since we still need the leaked Eng Kernel we still have massive performance and battery lose. There are guides to alleviate these issues but its still not as good as stock. Even roms like echo require it for root. So remember that before you jump in
1. Do we have unlocked Bootloader and Root for all US carrier S7Es? How is it done? I use people using Flashfire. So no TWRP?
There is no bootloader unlock for the US carrier variants of the device as of yet, senior forums members are guessing there probably won't be, either. What is being done successfully is rooting via an engineering kernel. Visit the carrier-specific sub-forum for your S7E model to ensure you're using the appropriate method and files when flashing. Flashfire is being used after the fact, for things like xposed. There is no custom recovery option for any of the US models that I'm aware of.​2. Does this process still trip Knox and render Samsung Pay to never be used again on the device?
None of the outlined processes will trip Knox, as they don't modify or replace the bootloader. Samsung Pay should still work fine when rooted, as far as I've read.​3. If I bought the Verizon variant, for example, can I root, unlock Bootloader, and etc, and then return to stock, to return to the store in case I don't like the phone?
The Verizon variant has some of the better documentation and support for root, but AT&T and T-Mo carrier models can also be rooted. I'm currently running the firmware for the T-Mo variant on my AT&T model and loving it. I'm not rooted, as the engineering kernel is absolute crap in terms of performance/battery life balance, but it is a fluid stock experience w/out bloatware.​4. Xposed Framework working for all models?
As far as I know, yes.​

Unlock Bootloader

Why in God's name are the bootloadera locked on The US variant of the S7 edge? Can anyone figure this out? Is there a way to port over Twrp im so sick of this phone and let the crap to root it.
There;s no way to unlock the bootloader and you cant install twrp on the snapdragon variants (except for the chinese variant.)
Blame the carriers.
But you can use FlashFire to flash stuff on your device with the current root method.
Current root method is using a engineering bootloader so the performace and battery is terrible.
We cant have nice things bro srry

TWRP

Help.... I have a ATT Samsung with Verizon G935U When I changed my op system to Verizon G935U I thought that it was unlock...boy was i wrong i am still locked down. I need to install TWRP so i can install custom roms. Can anyone help me with TWRP or am i locked down for good? Where is safestrap?
Alright so ANY phone in general from ATT or Verizion they are always going to lock the bootloader. So for 935U when it says unlocked it means carrier unlocked meaning you can use it on any US carrier (Tmobile,Sprint,Verizon,ATT,etc) that doesn't mean the bootloader is unlocked. ALL US s7 and s7 edge have the bootloader locked (whether it was Samsung choice or carriers idk) and there is no way to unlock it. So any Samsung phone that was made after the s7 just buy the international variant bc those bootloaders are unlocked and can have TWRP and custom rims installed, however you can still get root here's the link to the thread https://forum.xda-developers.com/verizon-s7-edge/how-to/root-method-nougat-t3566978
Sorry to disappoint you dude☹

AOSP Roms and TWRP ?

Hi there,
Quick question, Is there any TWRP and AOSP ROMs such as lineage os or Resurrection Remix OS available for US version of S7 edge ? ( G935T, G935P or G935A).
Sorry for noob question but, I cant seem to find any thread which mentions US models for aosp roms.
Thanks
Boot loaders are locked down tight, Not TWRP or custom roms. You can root, and do some mods like Viper4android, and Xposed, but that is about it.

Thanks for reply. Just few more question ? I have G935P with T-Mobile carrier and want to switch carrier roms to
T-mobile or unlocked version. any suggestion on that.
I did little research on that, I can see that all snapdragon models ROMS are interchangeable. But I am confused as G935U has different CSS such as TMB and VZW. and G935T has TMB. so how come unlocked phone such as G935U has CSS of TMB / shouldn't be it general css?
Also, I am concerned about partition size on different models as I can't seem to find PIT file for G935P or G935U to compare with ?
and what about KNOX counter after switching different carrier ROM ? is samsung pay work after flash ?
Thanks in advance for clearing my confusions.

No there aren't any roms because your variant has a locked bootloader.
There will never be a custom Rom for the snapdragon phones. At least not the north American phones anyway.
There will only be custom systems, which debloated systems. Nothing else, we can't get a new kernel, just new system.
