A while back I used a sprint rom for my Galaxy S7 to root my device. It didn't really work out in the end and the device would have issues every so often. Currently I have my phone reset to stock, is there a root firmware that I could use that is for a G930R4 model?
I am also a US Cellular customer and S7 user... I would love to know if there is a root that is specific for the US Cellular version of the S7.

I was messing around on videos and I found this video here, it seems to have been working on my phone so far, give it a try. It also has not tripped Knox yet either.

For my US and Canadian Friends - Do you guys think it's still worth buying the International F and FD models with no warranties in the US and Canada, and possible band incompatibility, now that the Sprint and ATT (T-Mobile coming up shortly) variants have Root via the EngBoot? Or you guys think that method will be patched soon enough and the future of Development and Root for the US and CA variants will be 0 to none like the S7 and S7E models?
Thanks for your input!

Lol responded to this on the T-mobile thread as well. If you want dev support I'd go for it. If not and just root, then go for the carrier version. They are all the same on the inside, minus the radio antenna, however it should work with the proper software.

Thanks bud! The root isn't that great on the local variants though, is it? I mean, you get the debug version of the ROM with extra binaries. It will likely get patched, so we'll lose root quickly I think? Finally, no Samsung Pay any way, with the Rooted ROM, right?
Lastly - None of the International variants will working on Verizon, right?

You do lose Samsung and Android pay. Root is good from what I hear. No mention of bugs or experience lacking so far. Not sure if it will work on VZW. Should though.
Hello,
I am planning on purchasing the Galaxy S8+, but I think I'm going to get the unlocked version when it is released. My question is whether T-Mobile wifi calling would work or not on this version, and if it doesn't, then would it be possible to flash a T-Mobile rom on my phone without any problem? Would all T-Mobile features then work as if it was an official phone from T-Mobile? Also would there be any downsides in doing this? I know no one knows right now for sure, but I'm just asking based on the past and whether it has been done before with the galaxy s7.
Thank you!

I don't believe wifi calling will work on the US unlocked version, but if Samsung manufactured the phone's the same as the S7, I.E. same hardware, then you should be able to flash T-Mobile's firmware with minor to no problems (I just flashed AT&T firmware onto a Sprint S7 and the longest part was downloading the firmware. I didn't gave any issues while flashing. But there's no way to tell we have that capability with the S8 until the phone has been released.

If you flash the T-Mobile firmware, yes. You should even receive updates from T-Mobile as well.

It's been done to the S7 countless times. Check out the forums and you'll see. I'd say the biggest downside is carrier bloat and certain carriers block some features that Samsung included in the phones.
I'm sorry if this question is answered elsewhere but can someone please tell me if it's possible to enable VoLTE for T-Mobile USA on the exynos DUOS variant of the S9+ from Singapore? If root is required, can someone tell me what steps are required to get there? Currently I have 4G service as reported by speedtest but whenever I place a call all the data goes away.
Not a total noob but almost.
Thanks
Welcome to XDA! T-mobile US VoLTE is not yet working on the Exynos DUOS. We will need someone like TKKG1994 to work his magic like he did for international S8 version. The CSC for Tmobile is built for Snapdragon so it will need to be ported to Exynos variant. Most likely, you will have to root to get there when it becomes available. (Thanks to the awesome devs here...)

thanks for the info! do you know if att VolLTE would work in the US on this phone?
None of the US VoLTE would work until one of the devs figure out a way to integrate it. AT&T requires an AT&T phone to register for VoLTE so your best bet would be to get an AT&T phone. Someone had success on S8 Exynos by providing AT&T an IMEI from AT&T branded phone and then using the Exynos with "US CSC patch" someone had combined. Hit the thanks button if you find the post useful

I don't think that's entirely true. I have a Verizon Pixel 2 and I get VoLTE on AT&T.

I think having a US model will always get you a better chance of VoLTE vs international Exynos model. I do not use AT&T or Verizon so I am not entirely sure but read a few other posts in this matter.
I bought S9+ from Samsung in Singapore. Brought to US, 4G works fine on Tmobile.
At first, I can't get 4G to show up. Upgraded software, still 4G does not show up.
Then I asked someone to send me a text message and I made a quick phone call. 4G showed up after that. I think it needs a synchronization.
Do you have VoLTE though? When you make a phone call does it stay 4G or does it change to H+?
On the Exynos variants you will get 4G data but not at the true data speeds and noVoLTE as I have noticed with my Korean variant. If you have already rooted and got things going you can follow a thread by a fellow international user on XDA who was able to achieve on his Note8.

When I call, I notice it stays 4G. Web surfing also on 4G. I notice it is a bit faster than my older S6.
Note that Singapore S9+ only has 4 bars signal strength, not like US version which has 5 bars. So you might notice it is lower signal strength but the dBm is probably the same. I have no way of measuring so I don't know.
Just FYI everyone, TekHD has forged a CSC flashable that gives all carrier features from Tmobile on international Exynos model. !!!
Link please?

I guess this is it. Looks very promising. Will probably try it out soon. But I hate to loose Samsung pay and secure folder...but then again. How many times do I really use that anyways?
Will going through this TWRP process trip KNOX? If so, is there any way to make Samsung Pay work again?

I thought this is just a CSC flash, which doesn't trigger Knox

You have to flash this zip with TWRP which I think needs root. I have been away from the scene since s7 edge but I'm pretty sure you need to root.

I also have a Singapore S9+ (XSP) 965F. Are you sure VoLTE works with Tmobile? That is awesome!

I assume this requires rooting though VIC?
I've been searching around the forums but I'm a little overwhelmed with all the info and I'm not quite sure what I need to be looking for. I used to flash a lot of ROMS but I really haven't messed with that much for a couple years.
Which version of the Galaxy S7 should I get that will allow root/custom ROMS and work on US ATT? (I don't care about Samsung Pay).
From what I can tell maybe G900U? or G900W8? or G900F?
I don't want to flash a rom unless I have to, but I can't stand bloatware or certain factory settings that can't be turned off (like the volume warning notification every time I connect to my car stereo with Bluetooth that I used to get on my Galaxy S5 before I flashed a custom rom).
Thanks
unfortunately, SM-G930 US version with snapdragon chipset cannot flashing any custom rom (bootloader locked). flash the US firmware on your S7 ATT for much less bloatware
Thanks, but I don't currently own an S7. Just trying to figure out which version to buy that will work with ATT but also allow root/etc.
if you really need to root your device, maybe international version of S7 is for you. or the canada version SM-G930W8
Rooting US models means using an engineering bootloader, which restricts your charging capacity to 80% and causes stability issues.
If your desire is to root and/or custom ROM you'll want the G930F/FD/W8
All will work with US carriers, but they don't have the full band support so network speed may vary. But there's plenty of G930F posters here inside the US.
I just received my new phone today as my secondary rooted phone, although I now feel like I bought the one wrong model out of the bunch.
For the life of me I cant find any way to root this phone online, I am hoping someone can tell me if its possible. I dont care if I trip knox or its a paid program i have to get to run, I just want to make it happen. so any and all help would be appreciated.
I am truly sorry if there is a current thread that answers this, but so far everything I have found is pretty old.
On a similar boat and it seems that Nougat cannot be rooted. You can downgrade to 5.1.1 and then root but that seems not worth it as you are giving up features that are available only in Nougat. I myself might just switch to a tmobile S6 motherboard. I have the Verizon S6 variant but I'm on T-Mobile.
I can really care less about the services lost in the downgrade. If you know how i can downgrade to 5.1.1 to then mod, I'd still love to do it. I already have a S9+, S8 for back up and an apple s6. I really want to mod this Verizon, or it will have no use

I'm fine with downgrading as long as that means I can root my phone, is there any kind of tutorial for downgrading?
