Hi mate
Not sure what you want.....
for the S7 International there are many CSC ... is not just one
You can flash any G930F firmware in your phone that is not an issue....you must care that it has your required language and that the selected CSC has your carrier specific options...like wifi calling , Volte......
What country are you from and what carrier do you use?
BTW you said your phone is broken...what happened?

Use SmartSwitch Emergency Recovery mode. Do not connect the phone, but type in your serial (not IMEI) when it ask for it, and it downloads the ROM for your device original market (which is may not the same as your country if you bought it online)

Unlocked SM-G955U

Last year's S7/S7edge had a different model number for each carrier (G935A/T/V/P/R4), but this year they all seem to be using the 955U model with different CSCs for each carrier.
I noticed on SamMobile there's an unbranded firmware available for the G955U with the XAS CSC, what CSC is that? Generic?
The reason I ask this is that because these US variant phones get imported to Pakistan and some people buy them since they're cheaper than the officially sold G955F models here, so if a G955U gets imported here which for example was previously used on T-Mobile in the USA, if one flashes the XAS ROM, will it basically be an unbranded Snapdragon 835 S8+ or is removing the carriers CSC not possible?
All replies will be appreciated.
Cheers

The U version is locked and not able to root. It's used by all USA carriers and they probably made it locked down due to Samsung pay. At some point a root crack will surface but it probably won't be stable

I don't need root though.
Just the possibility of flashing an unbranded ROM with no bloat, something that won't be used with US carriers.

You cannot flash firmware without rooting on this device. That's my point. When you try flashing in Odin, nothing happens. That's why you cannot root or even flash things. Got it? You need root in this case.
I think we are after the same thing; xas is sprint from my understanding. xaa should be the "unlocked" carrier neutral you are looking for. There is a thread in the s8 forum where some people had success flashing parts of the Canadian firmware then refreshing parts of us firmware they had quasi obtained this but I have yet to try
https://forum.xda-developers.com/galaxy-s8/how-to/rd-carrier-switch-root-snapdragon-t3597473
I read somewhere that only G955f models can change CSC firmware using Odin.
G955U models won't be able to... I could be wrong...
Then again, we won't really know until someone buys the U model and tries it out for themselves.

What did you find out?
What did you find out? I'll try it with mine but I need help. I am by no means a schooled veteran in the world of command lines and tech talk but I can follow direction. I've managed to unbrick a couple LGLS 675 and bypass frp (for myself) a couple hundred times. I'll post a screen shot of my about phone if you guys are interested.

im using a 955f (so could be different on your phone), but just turn the phone around, on mine the S/N stands printed on the bottom of the backside, you can slightly see it ->here<-
and also I'm really not sure about that, but i believe some Serial/IMEI/whatever-numbers do stand in download mode
EDIT: By what i've found google'in, on the 955U, just the IMEI is printed. Sorry

G955FXXU1AQH3 unlocked, bloatware grabage problem.

Hey fella's, and ladies. I just got my G955F, bought inside of the US off of the same person I usually go through. Turns out It's a UK model that came with Vodafone bloatware and shows 4G instead of LTE (even though it IS LTE). Is there a US variant? And if so can I flash the phone with any G955F variant software using odin? So I guess I'm asking, what is the best, and purest firmware if I am in the US. I have T-Mobile and I'm in Cali. Thanks ahead. (Sorry, but I posted this in the S8 section originally, like a dumb-dumb)
Also, could I flash with G955U unlocked firmware?

Here you can download the US ROM and use Odin to flash - these are official ROM's so Knox will not be tripped
NO
You CANNOT flash a G955U rom to a G955F device
It will definately soft brick or even hard brick your device
You can flash this rom ( https://www.sammobile.com/firmwares/galaxy-s8/SM-G955F/EUR/download/G955FXXU1AQH3/184528/ )
No bloatware, multilang and fast updates.

DON'T GIVE WRONG INFORMATION!!!
If you don't know what you talking about, then say nothing!
You CAN'T flash G955U FW to a G955F
Do you know the difference between the G955U & G955F?
If you did, than you would have known the answer!!!

Read the post moron
He has a G955F phone with a UK ROM on it... he wants a US ROM so the link takes him to the US ROMS for a G995F phone
I didnt answer the last bit about the G955U as I only just saw that - and just to clarfiy the G955U is the Snapdragon version so no, a Exynos ROM will not work

Got it. Couldn't find any US firmware on that page. Part of my question about the US firmware, or multilang firmware comes from the fact that Walmart sells G955F's. I would imagine whatever firmware is on there would be what I would want. Just don't know what that is.
-Thanks for all the replies so far. If I can't figure out what firmware comes on the US Walmart G955F phone, I suppose I will go with the variant listed above.
-Also, will VoLTE work on the multilang rom? Or is there a rom that works with T-Mobile and VoLTE? And if anyone is wondering, I wanted to Exynos variant, that's why I didn't buy G955U.

Well, I went ahead and used this firmware. Really like it, no problems at all and its exactly what you said it would be (hopefully its got great support as well). Appreciate the direction. Thank you.
If anyone finds out what comes on the US released (Walmart) G955F, I would really like to know. I've been searching and searching, and can't seem to figure it out.

No problem. Im sure that you will like it even more
If you can, please share a pic from the device info to see which CSC do you have
Hi guys, I've just got a G955F as an upgrade from Vodafone UK with lots of their bloatware. Can I flash any other firmware over it without tripping Knox or invalidating the warranty? I'm in the UK btw.

Galaxy s8+ japanese

which variant do i use for galaxy s8 from japan? Sm-G955J / SVC35
Please
variant of what? you looking to stay w/Japanese or go to another region/country?
I just want to use an operator-free rom stock, but I can still use it in Japan
Thanks for help!
What's Japan use for cell svc, GSM? Exynos phone? If so pretty much any custom Exynos ROM, with the version appropriate CSC ought to work just fine.
Maybe it's out of topic, but kinda similar with my question, and the last reply is still quite recent.
I just got a used s8+ g9550 (TGY/Hongkong). I looked at Phone Info app, it comes with Hongkong PDA & CSC (G9550ZHU1AQG6), and US version of BL & CP (G955USQU1AQGL). Still on Nougat 7.0.
It works just fine here in Indonesia. But I'm afraid it won't be getting any OTA updates since I'm not living in China. Is it actually OK to mix up the firmware (AP, CSC,BL,PDA) like that? What versions are compatible with my device?
I'm totally new here. I don't even know why there're 4 firmwares for each device, and what each one of them is for. All I know CP = Modem/Baseband, BL = Bootloader. Mind to explain it to me? Thanks

I beleive your phone is a snapdragon processor not exynos - if it is chinese, I think there may be a way to unlock the bootloader but I am not 100% sure of that. I know that the S7 Chinese was able to be unlocked but there was a special ap you had to install in order to do it.
I know I haven't helped much but I wish you good luck...
