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.
Hey guys!
Yesterday I got a Sprint carried S7 SM-930P as a gift. The only problem is that although it works flawlessly on my sim cards (I'm not in the US), I found out that the 930P won't get the 7.0 update. Is it possible to flash the G930U firmware without messing my phone up?

I wouldn't do it unless your absolutely sure, I wouldn't be so sure if it's for a different model number. If they were able to have the same firmware flashed Samsung would just release it, they obviously didn't because it requires extra effort, pointing towards the conclusion that the firmware is not flashable on 930P

You can flash it, i have done it myself. There are many guides over here that tell you how. All S7s in the USA are the same exact thing hardware wise, only the software (firmware) is different. Am currently running SM-G930U firmware on an SM-G930VL S7. @op the sprint s7 (SM-G930P) already has android 7 as of last 3 weeks

SM-G930P converted to SM-G930U
Hey guys. I was able to flash the sm-g930u firmware downloaded from sammobile... the problem I have now.. I have a blank csc. No product code.. and on software updates it fails to register my device. Also in settings . I have some weird options. Which some of them are repeated. I will upload screenshots.. Also there's a system UPDATE option and also software option. Which one of them fails to register and the other only works with Wi-Fi. Should I revert back to my stock sprint firmware. If so do I need to wait for a firmware with same build date or newer. Because on sammobile haven't uploaded a firmware with a build date on par with the current install. Then I would have to wait right. ? If using a older firmware it will brick or do something to my phone ?

Did you flash all file in the SM-G930U folder (AP,BL,CSC,CP)? Because i did it with T-mobile,Verzion an it work fine
Thanks for the reply. Already solve.. what happen i flash home_csc. So ir was like that. But then i made a back up.. and flash again using the csc file. And all work perfect. At first phone was with the SPT csc.. then after i restored phone and pop in my sim it did something.. and now I'm with XAA csc. Works perfect. And could receive updates (phone registered). Just waiting for the july security patch update. Btw phone works better in every way.. battery even last longer..

Hey buddy.
i need some help here with that Home_CSC.
i'm from morocco and my phone is also unlocked to use my service provider SIM card ( maroc telecom) but I'm stuck at marshmallow 6.0.1
and I need to flash the U firmware to get rid of bloats and get OTAs but i don't want to screw something.
please can you make it clear what CSC to flash with ? and how so ? I mean like Screenshots.
and forgive my Noobie questions.

Hey Buddy. I would recommend doing a full back up on your phone., using Smart Switch app
It saves all your numbers, message, etc..
Then proceed to flash the latest firmware for the Region or Provider. Using (CSC) not (home_csc) which means flashing the csc will wipe your phone data. Phone will be like new again. Proceed tru set up. Loggin in gmail. Proceed to update smart switch app if not found in apps. Then restore from the back up file. And good to go.

actually all S7 are not the same hardware fyi. The Sm-g930p has chipsets snapdragon and uses cpu procesaor quad core but the sm-g930F has the chipset Exynos8 cpu is octa-CORE the chipsets vary from these two. Flashing firmware for one chipset to the other may cause major problems bot to mention bootloops.. but I looked up sm-g930U and it uses the same processor as the P model.snapdragon

He said all S7's in the USA are the same, which is correct. Exynos/930F isn't sold in the US, only way to get one is to grey import.
You can flash any USA model's firmware onto any other USA model because they're all the same hardware.
anyone running the 930p with current update how did you get around the binary 6 lock all the 930U firmware versions I can find are binary 4 I think t-mobile is 5. Anyone got links to a firmware we can push to sprint variants that are binary 6.

You can't get around it. It is currently impossible to "downgrade" the bootloader binary version. All US carrier variants are version 4, except Sprint that is 6. You are stuck.
The only way it would ever be possible is if (a) one of the carriers, in a future software update, increases their bootloader version to 6, or (b) if someone figures out how to unlock the bootloader for the Snapdragon models.
Neither of those options is likely to happen, ever. You might get lucky and hope the G930U unlocked version has a higher number (it hasn't been released for Oreo yet), but I wouldn't bet on it.

Well this is all very sad all this bootloader nonsense has me thinking Im done with samsung. I need to look for any phones where this nonsense isn't happening.

Blame Sprint; there is really no reason for them to do what they did except keep users from switching their phone to another carrier. This isn't a Samsung thing. I don't believe you would be able to do this with any other Android phone, either (i.e. go backwards in bootloader versions).
Hello,
I live in Switzerland and have a Exynos Galaxy S7. Will looking for accessories on Aliexpress, I noticed that the refurbished US variants sell for a huge discount compared to the SM-G930F (up to 80$) version. I saw that the G930F seems to support all LTE bands will the other are more constrained (but the AT&T version supports all the bands used in Europe as well). So my question is are they simlocked? Would they work in Europe (out of curiosity)?
Thanks
No advices?
You can get carrier unlocked US models which will accept any SIM, and they should work in the rest of the world. Of course network availability would vary, but you've already checked that. So if the US model supports all the bands your carrier uses you should be fine.
Only problem is the US model has a locked bootloader, so you can't use a custom recovery or ROMs. From memory root is possible but doing it is a bit different.
I'm not sure if you'd be able to flash your carriers CSC onto a US model phone, since the CSC would be built for the 930F. Which means OTA updates etc might not reach you, and you'll have to manually flash firmware updates.

Thanks a lot for your detailed answer
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.
Hey Guys, I am in desperate need of help.
So I bought the note 20 ultra (model N986-U) from a seller in Texas (I live in Canada). The phones original csc code was ATT/ATT/ATT. I have a rogers sim card (csc code RWC). I noticed the phone is still stuck on One UI 2.5 because I am not connected to the ATT network.
So I tried changing the CSC using SamKey. I bought some credits, followed the steps and now for some reason my CSS is XAA/XAA/ATT.
I understand now that my phones model does not have a RWC firmware. Frija can't find the software for the SM-N986U running RWC but has no problem finding the software for the SM-N988W running RWC.
Is there any way for me to update my phone without bricking it? In an ideal world I would get OTA updates. Can I download the CSC_HOME file from the SM-N986W and flash it on my SM-N986U?
I'm really sorry for the noobish questions, I read so many threads and watched so many videos but I don't have the balls to experiment with such an expensive phone.
I know you can flash U1 firmware on a U device without any issues.
That's what I did to mine.
As for flashing W software on a U/U1 device, it's technically possible considering they are identical hardware, but I cannot say for sure what impacts it might have to the phone's performance.
You can always manually flash current U firmware.

Hey thanks for the answer,
I ended up flashing the W firmware on the phone and it worked flawlessly! Now the phone shows that it's a model N986W. OTA updates still don't work tho, even though the csc shows RWC

Glad it worked. Grab the latest firmware for RWC and then wait for the next update. (N986WVLU1DUB5)
