Can I flash ee uk firmware on unlocked snapdragon s8 plus?

I've just bought a galaxy s8 plus on gumtree and just realised it's an American unlocked version. I wanted to flash EE firmware to enable Wi-Fi calling but I'm not sure if it's still possible using Odin as the uk phones have different chipsets.
Can anyone confirm either way?
Thanks in advance.

Snapdragon variant phones don't support the band's here in the UK so I don't think it will work. Vice versa an exynos variant won't work in the US

I was afraid that would be the case.
Thanks for letting me know.

The phone does work ok here in the UK along with 4g. I don't expect to get. As good coverage though. Are you sure it wouldn't work?

flash exynos rom on snapdragon , great idea if you want a brick. No joke, it won't work for sure. and if you flash the Exynos firmware with odin , including bootloader , it would be an hard brick, won't turn on , no more recovery or download mode, just completely bricked. So just no. and wifi calling is nothing to do with the phone but with your carrier and or your current subscription. if your carrier doesn't support wifi calling you won't have that option, so other firmware or even force to show that option changes nothing as you would have the same carrier .
and of course a csc (firmware depend of the country) works only with the right SIM card , I mean samsung block the phone if you use an American SIM card on a European phone. European phone works only with European SIM card and European carrier

Dude what?
http://m.gsmarena.com/network-bands.php3?sCountry=United+Kingdom
https://www.frequencycheck.com/mode...-sm-g950u1-sm-g950w-samsung-dream#frequencies
Supports all 3 lte bands used by the UK, 800 1800 and 2600.
Supports all 3 GSM bands used by the UK.
Supports all 3 utsm bands used by the UK.
So in other words you were 100% incorrect
All of the high end phones have been quad band in the us for years.
I really hope this guy didn't just blindly listen to you and dump his phone for cheap.

The other person could not be more incorrect your phone works fine in the UK, along with every other high end us phone for the last like 10 years
I hope you still have it and didn't dump it for cheap because someone decided to open their big mouth without actually checking that their gut reaction has any basis in reality.
I don't know if there is full CSC support for the UK carriers, but all u1 phones are direct from Samsung and sim unlocked at the factory so you will be able to pop any uk sim in there and be able to use data/sms/voice etc no problem. What provider do you use? I can check my /system/omc directory and see if it's preinstalled by the standard is CSC package.
It's also quite likely that if not you can install the local CSC package that comes with exynos phones on yours. Not only are the other posters 100% wrong about the SD/exynos phones habing incompatible operating systems*, but even if there was a shred of truth to it the CSC package is mostly config files and images and whatnot anyway, so there little execution going on
*It has nothing to do with exynos or snapdragon they are both arm64 lol. If anything it's because Samsung kneecapped them to make sure it wasn't possible for licensing/snapdragon bootloader security or some other stupid thing.

Hi
Thank you so much for taking the time to write such a long and in depth reply.
I did reply to the guys post earlier stating that it the phone works absolutely fine on 4g LTE. I just thought he misunderstood me. Or vise versa. I've not dumped the phone because it works fine. Even if I can't get WiFi calling sorted I will still be keeping it. As long as I can still get updates ota I will be happy..
I bought a note 5 a few months ago not realising it was an AT and T model. That was a pain because it was stuck on lollipop and wouldn't accept any ota updates without an AT AND T sim card.
So I was just a bit wary of that happening again. But with this phone being unlocked I'm sure updates will be just the same as UK phones. (hopefully).
Just for the record my phone is running on E.E. carrier.
I've not checked if it's ever been rooted before.
How would I check?
Would a root checker app do this?
Thanks again
Simon.

The phone is not rooted now but I'm not sure how to check if the phone has been rooted before in the past.

There is no way to tell if the phone has been system rooted which is all that you can do to the us s8

I bought my Galaxy S8 from New York, after a while I realized that my phone is US unlocked version, now I live in UK and I don't get any updates for my phone at all since last year, I tried to flash it but it didn't work.

T-Mobile version using custom modem again?

I am sure we may need to wait for Friday or what not, but does anyone know if T-Mobile will be selling a custom OP7Pro with a custom modem so you cannot grab updates directly from OP as they did with the OP6T? Just trying to figure out if I can get from T-Mobile and be good or have to go direct with OP.
Thanks in advance.
Ps. I did see the other thread on the modem channels, but didn't know if that was related to my question. As I just want to ensure the phone I get can be fully supported by OP and not just my carrier for future software updates.

OnePlus told me there is only one variant of the OP7Pro globally. via chat and email

Like previous OnePlus devices that have been on T-Mobile. The firmware is the only difference outside of the second SIM holding being filled. Cutting it out or using a tray with dual-SIM's and the non-T-Mobile firmware will enable dual-SIM. The modem only differs by firmware. Band 71 is available to devices with the T-Mobile modem firmware installed. This firmware can be installed on the Global version as well. Once the devices fully launch, expect ROM's to start popping up with enabled dual-SIM for the T-Mobile version and Global versions with the T-Mobile modem firmware.

Okay thank you both for your comments. Glad they are not doing the hardware differences this time around. I just know from forums that the T-Mobile variant of the OP6T is slow to get updates when compared with the international version due to the custom modem. I am not too worried about the second sim, don't travel much. But unlocking the additional modem channel would be nice on the international version of OP7Pro. I think I have the details I need for my decision. I will do the international version from OnePlus direct to limit the delays on software updates. Then just watch for mods to upgrade the modem firmware to work better with T-Mobile.

Will we even need the T-mobile firmware for band 71? The review that GSMArena put out said that they were able to use band 71 fine with their review device. I would think that the devices that Oneplus sends out to journalists would be the unlocked version.

More than likely, no. Swapping out the modem firmware for the slightly tuned version though, is something some on T-Mobile will want to do. Most journalists received the 12GB/256GB unlocked global version. T-Mobile likes to tune their radio firmware for devices sold by them. If you look at the Galaxy or Note lines from Samsung. The S9's and Note 9 support band 71 on the U1 non-carrier specific firmware, but also do on the TMB U T-Mobile specific firmware. The difference is, carrier aggregation in the modem firmware. Ultimately, it isn't a big difference, as a former S9 Plus and Note 9 owner that has tried multiple firmware on each.

We tried swapping modem.imgs it doesn't work. Causes mismatch and won't boot. And once u convert a tmo OnePlus u get ota's. No one will want the tmo software cuz it usually is missing every cool extra.. and they push it with an Android 6 about phone menu..blah.

What is the difference between US version N986U and N986U1?

Anyone know what the difference between the two? Or if there is a differenc e at all. I am on ATT network in US.

Carrier unlocked U and factory unlocked U1
U is for the carrier variants in the US. U1 is for the factory unlocked version which you buy directly through Samsung. Even though unlocked, the U model will have a carrier logo when booting up. If you want true unlock, go for U1.

Can I flash N986u1 firmware to my galaxy n986u ? Will i loose esim feature? I want to do because I am not getting 5G and also ota updates

If you flash a note 20 (or other Samsung phones with Knox for that matter), you'll permanently blow an efuse which removes some phone features like Android Pay. I didn't think that the esim feature was one of those features but I'm not totally sure on that.

Guys, i need a fully support arabic language
For
SM-N986U​
should i change to U1?
its already unlocked phone with Verizon
so any sim is working
but the 5G is not working
AND a full arabic is not there.
if i changed to U1 will i get a full arabic lanaguage? ?

As for 5G with Verizon, check the coverage map in great detail! Unfortunately, you may find that it just doesn't currently exist where you're testing. I've had Verizon Reps (at multiple stores) argue with me that 5G coverage did exist in areas and eventually find/admit they were wrong.
After doing my own research on Verizon coverage, I've found that their 4G LTE coverage is very good, but their 5G coverage is pretty much only in (5G mmWave) and around (5G UW) big cities and even spotty in those locations. When Verizon claims they have "Nation Wide 5G", think of coverage which looks kinda like a chain link fence. Verizon is spending much money to fix this lately, so hopefully it will improve quickly.
For the time being, I've abandoned Verizon for T-Mobile because of its indisputably superior 5G coverage in the US.
N986U vs N986U1: As for switching to a U1, I'd say don't. I have an N986U and my wife has an N986U1 and I get Android updates much more quickly on my U and she does with her U1. It's weird but true.

AT&T firmware on Unlocked version

I've been using the unlocked Z Fold 2 but in need to use Wifi calling which is missing so I would like to know if it is possible to flash AT&T firmware to get Wifi calling? If so, how? Also, will I be able to switch back as well?

There is no AT&T firmware available, nor will there ever be, most likely, which is why my unlocked Fold2 sits on a shelf and I use the AT&T Fold2 that I purchased from AT&T. Either live w/out wifi calling or switch to T-Mobile or buy an AT&T Fold2.

Aaaah, that's not what I was hoping to hear. Oh well, look like I will be buying At&T version of Samsung phones again..... even though I hate all the bloatware.

There's WAAAAYYY more Samsung bloat than the teeny weenie bit of AT&T bloat that's all disable-able anyway.

Yes, it's absolutely possible. Has been since the Galaxy S8. All the US versions of Galaxy devices are identical. The only difference is the firmware, which is cross flash compatible.
Two caveats:
1. ATT firmware is not as readily available as other carriers, but it can be found. If/When Samsung upgrades the Z Fold 2 to BYOD firmware, that won't be an issue.
For now, check this thread for the ATT firmware:
F916U AT&T Odin Firmware Links
For those who don't know, F916U is the model number of all of the US carrier versions of the Galaxy Z Fold2 5G. The F916U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100%...
forum.xda-developers.com
2. If you flash ATT firmware to an unlocked device, you will NOT receive OTA updates. You'll have to manually flash each new version with ODIN. ATT is the only carrier I know of that does this.

AFAIK, out of all of the "U" models of the Note20 Ultra, only the T-Mobile version has eSIM capabilities. There's a couple of threads around here in Note20 Ultra land on the subject.... I'm not sure if flashing the T-Mobile US firmware will bring up the option on a U1 device.

This worked in the past, flashing TMB firmware using modded Odin.
However I have a new Note and have tried many times to flash TMB firmware but cannot get it to stick. I am stuck on XAA CSC.
There is another thread where people got it to work originally however I am wondering if Samsung did something to the bootloader to prevent the CSC change. I really want to get this to work , if not , I may return it, still have a little time left. Plastic film still on phone
