I have a Samsung Galaxy S7 from US Cellular SM-G930R4. I'd like to use a custom ROM with it, but I'm pretty sure its a Snapdragon, and from what I see on these forums, all the custom ROMs are for Exynos. Why is that, and are there any compatible ROMS I could use?
Thanks
US S7's are all Snapdragon models, which all have a locked bootloader. With a locked bootloader you can't modify the boot image which are what custom ROM's change. So no there aren't any compatible ROM's for your device.
Exynos lets you unlock the bootloader easily, which is why it has all the custom ROM's.
Hrmm ok thanks for your reply.

Hey XDA,
I just recently purchased a AT&T S7 (SM-G930A). I also just recently found out that AT&T doesn't push updates to non AT&T network phones. I am using the phone with T-Mobile and I was wondering if it was possible to flash the T-Mobile stock rom without tripping Knox or anything of that sort. I remember being able to do this to my AT&T Note 2 back in the day. If it is possible, can someone kindly link me to the file and instructions on how to flash the stock ROM from T-Mobile? Thanks!

DO NOT DO IT . I believe AT&T has the exynos processor and I know for a fact T-Mobile has the Snapdragon processor I'm pretty sure you will perma brick your phone. Tmobile also has a locked bootlaoder.
Just change your APN settings
Actually, I posted this in the AT&T forum as well and they said it work fine and it did. The phones are identical. The problem is that I can't go back to AT&T stock because AT&T is still on BL V2 while T-Mobile is on BL V3. I flashed anyway and it worked fine. Make sure to use Odin 3.12 from the Verizon Root Guide!
All US carrier S7's are Snapdragon based
@goofwear, All US based S7 and S7E have the Snapdragon SOC. And ALL have a LOCKED BOOTLOADER. @IbbiAnsi, you can flash just fine. Just read more about them in the threads and follow at your own risk.
I am using Android phones since several years and had no problems finding ROMs and flash them. Bootloader Unlock was no problem back then on Galaxy S1, HTC One S, Nexus 5 and Galaxy S5 but it kinda surprised me that the S7 is my first phone which will "probably never" see an AOSP ROM because of the locked bootloader and the unknown software architecture of Exynos processors.
What has happened that pretty functional and stable AOSP ROMs are now blowing up on XDA?

What locked bootloader? Did you not know that aosp and exynos doesn't mix before you got the s7?

see the Exynos development forum there's a bunch of AOSP ROMs there now.
I'm also wondering what changed to facilitate all these ROMs working on the Exynos S7.
magic dude, im telling ya, in a period of 2 months, they already made it bootable and stable enought, not for daily usage, but really near to!
I think some devs were working to get aosp on exynos and Samsung.

Good to hear, still unrooted so i barely visit that section. When i bought the phone when it came out i knew it probably wouldn't get aosp, but after using touchwiz i really don't miss it.... omg i've said it!
Are there any roms right now that support the sprint edition sm-G930P Galaxy s7. Every rom that I have come across appears to be based on the international G930f version. Apparently since the oneplus is not compatible with sprint networks I am basically forced to either get the s7 for something comparable and flash it or switch carriers. Any recommendations?
Snapdragons are bootloader locked, if you have root for 930p you may have a working custom rom (check T-Mo forums)..
Is there not a working root and custom roms and mods for the s7 through att yet? I'm looking here and not seeing too much. Before I get the phone I want to make sure there is a root and custom rom support, etc.
Speaking for the ATT version btw.
What you see in https://forum.xda-developers.com/att-galaxy-s7 is all there is
From memory the required documentation/software for working with the S7 snapdragon implementation has never been released.
I have a J700P. I want to install a Rom, butt not a stock debloat deodex....I can do that myself, but that's all I'm seeing for this variant. I've been out of the Sammy loop for a minute and just acquired this j7 that was FRP (like.. Good too) and ready jump in on an unlocked bootloader.
It's looking like I'll need to learn to cook a Custom Rom myself huh.... And yes I plan on trying the Lineage build for P variant. Basically just wanna know if anyone had tried any of the kernels or Roms posted F/M/H on the P or if that's feasible. Thanks guys.
