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

Use Firmware Of A Different Model

Hi,
I have a S8+ with the model SM-G955FD and was wondering if I am able to download the firmware for the model SM-G955F?
The phone was purchased outside of Australia and doesn't use the Australian (Telstra) firmware that I would like it to. I just figured they are the same phone just different model numbers so there shouldn't be any issues right? I might just lose a couple features or something but the phone should work correctly?
Thanks in advance.

Yea, the G955FD is the dual SIM Exynos variant, right?
I'm sure the dual SIM uses the same firmware as the single SIM, so you should have no worries flashing Aussie firmware.
But I would suggest you flash the XSA (Aussie unbranded) firmware, not Telstra firmware. You'll lose nothing, but you'll get faster updates.

I thought as much, thanks so much for clarifying. I will download the XSA firmware as well.

I'm using Metro PCS service on a Singapore XSP and experiencing some terrible 4G service. Is there anything I can do about this, looked perhaps flash smother CSC onto my 955FD?

2 - Same network Bands supported . The ROM contains the programs on how to operate in different frequencey bands .

Hi there I am a silly person who purchased a Galaxy S8+ from Kogan which is flashed with Emirates firmware
Its model SM-G9f55FD G955Fxxu1AQL5
No VOlte and Samsung pay etc
I need to use Telstra network (im rural but in a VOLTE area) and so I need to flash it with Australian Firmware so it gets all the local features.
I would just like to know how I know what chipset to use - I dont think its snapdragon
And where to get the firmware.

Here's the XSA (Australia) firmware:

Flash it. Doesn't matter if your device is G955F or FD, the ROMs are exactly the same.

Does the method works with G955J SCV35 model? I'm running NTDocomo firmware on KDDI model to unlock network (single SIM) . I wan't to flash unlocked U firmware but getting scared that the phone will be bricked.

Flash SM-G930F firmware on SM-G930L phone?

Hey everyone,
I picked up an S7 SM-G930L yesterday which has come with a lot of bloat.
I'm hoping I can just flash over it with the SM-G930F international firmware. Does anyone know if this is possible?
I tried searching for an answer in other threads, but couldn't find anything which said it would be possible. There's a bit on the US variants of the S7, but I found little about the G930L.
Does anyone know if this is possible?
Thanks.

I'm pretty sure that if you are planning on using Odin to Flash a different Firmware it's going to fail... That's based on my experience trying to Flash Tmo Firmware on a Canadian Note device (accidentally by the way) - But it definitely failed..... You may have better luck with the S7 - But I wouldn't count on it.

No man. It won't work. Just use a custom firmware and by the way, g930l has an unlocked bootloader.

I have tried mine bro. It just don't work. Odin keeps on failing.

Thanks for the replies.
However, I actually noticed on the back of the phone that the model is SM-G930S, despite the firmware being SM-G930L under the settings.
Seems like the shop I bought it from (refurbished) have reflashed it. I may actually give it a go and try the G930F firmware.
Does anyone know if I try another firmware if it will brick/cause an issue with the phone? E.g. will it wipe/reset the phone, or require me to reflash the original?

Also got smg930l phone. Please let me now if you find any solutions. Sms on this is really sucks.

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!!!

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.

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.

Flashing My Note 20 Ultra 5g N9860(BRI) with SM-N986U1 firmware

Hi,
I was wondering if its possible to flash US unlocked firmware onto the unlocked dual sim Taiwanese variant of the Note 20 Ultra 5G (SM-N9860).
There are certain features like Samsung pay that is somewhat limited for me because its still shows the region as Taiwan.
Of course I don't want to brick my phone but wanted to see my options in terms of changing the region to a US version.
Also, just to confirm, there is no way for this 5G variant to get 5G with US carriers, correct?
Thanks

SAme question here.. can anyone help please? also can anyone help in this issue:
I am living in UK, have note 20 ultra 986U1. all 5g Bands are not active, on android 11 (UI3.1) there was a way to access to service menu and enable all 5bands. and I was using the 5G here. now, I updated, and that can not reach seavice menu to enable right 5G band. anyone has any idea what should I do? even I can not flash with UK rom, as UK rom is for Exynos, but mine is snapdragon. any other idea maybe? or other rom that works with my phone and also enabled 5G bands?
do you think if I just change the CSC , my problem will solve? if yes, which CSC I must flash and how?
