What NA firmware can I flash onto my G920I?

Hey guys. I'm visiting India from NYC and bought a Galaxy S6 here. There are a lot of region specific things on this firmware that I do not like. For example, when I add new phone numbers, the automatic formatting of (xxx) xxx-xxx does not happen. Numbers just save as xxxxxxxxx and I have to manually add the formatting. This is just one of the many things that are bugging me. I want to flash an NA or equivalent firmware on my phone and was wondering what the most optimal firmware would be to use? Should I use a carrier branded firmware from T-Mobile or something? Does NA have a non branded firmware at all?
Thanks so much in advance!

Digits after firmware number

Sorry to ask, might be a silly question, but I haven't come across this in my reading (or searching) . . .
. . . what do the digits after the firmware version number mean?
The current latest UK customised Z3 firmware is 23.4.A.1.200 / R9C
The UK's O2 firmware is the same number, but ends R11C
What does R9C and R11C mean?
Is R11C Release 11C, and therfore newer than R9C, or am I way off??
Thanks.

N915T using SM-N915F?

i've note edge buy from people in my country *Indonesia last month, when i check in about phone setting it's written Model Number "SM-N915F" that i know it is for Indonesia, but when i put off my battery it's written N915T that's for T-Mobile, so i'm confuse with my phone because i can't do an upgrade from setting/about/update and is it posible to flash N915F firmware to N915T?

If it write T model in the back, then it is the T model because you can change the model number in about phone, so maybe the owner changed the model number before you bought the phone. Even so If you are undecided, you can hardreset ur phone and after succesfull bootup u can find out what the phone model is in about phone... :fingers-crossed:

No you can't.. on T-mobile version only 2G will work. no 3G or 4G..

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

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...
