Go to the S8+ device get and in Guides, News, and Disscutions look for my post with Snapdragon Carrier Switch. I have everything there.
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] jchl97:
Personal experience here. So I decided to get my feet wet by flashing

G950U1 on my ATT G950U upon reading more confirmations of the firmware matching that of the actual unlocked model, just to be careful not messing anything up.

Following the brief yet sufficient guide in post #2 my ATT (already network unlocked) device is perfectly transformed into the unlocked U1 model - nothing really tells them apart besides the FCC label on the back (U or U1) and that's it, AFAIK.

Internally you get the official unlocked firmware that does not include a "Service Provider SW. version" and instead configures to adapt to different SIMs. I was able to try this out overseas and each time I switch from my ATT sim to the overseas carrier and vice versa the device will prompt to reboot and configure itself - perfect.

Several features change upon switching carriers for example the dialer hidden menus (eg 4636, 2263) will be disabled. RAT selection option is actually restricted when in ATT so I wasn't able to configure cellular bands. Anybody know why?

Wifi calling and volte are nowhere to be seen on both my carriers which I assume it's just a support issue - it should work for TMO users upon that auto config process.

But then the bottom line is I'd rather trade those with a clean, fully official and stock, carrier brand/bloat-free and a nearly generally bloat-free (FB and some Hancom office editor not uninstallable) phone as one would've bought as unlocked. Will have to see how the battery goes but so far so good and I expect it to be even better.

One outstanding, unidentified hard/software issue remains that is the home button issue - for those unaware I urge you to refer to this post (https://xdaforums.com/showthread.php?t=3600575) and see whether yours is infected - this should be much more widely acknowledged given how many people has reported on it.

[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] eduardmc:
is the speed really noticeable on U1 compare to stock tmobile. i mean stock tmobile firmware is already flying. another thing, when we had the unlock firmware for s7 edge was how slow the unlock USA model use to get update. it was to the point that all carriers had the nougat except the USA unlock model. i know it was eventually release but it was like 4-5 month after tmobile nougat update.
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] Duck Quan:
I have U1 firmware on my Sprint GS8 but speed is not noticeable. Bloats all gone but that's about it. I think it's just as fast. Only downside is I think the battery life with the U1 firmware is worse. Standby time is horrendous. I might flash back to Sprint firmware just for battery life
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] co.ag.2005:

[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] elliwigy:
personally my battery life is better.. i have verizon tho and on U1 firmware

[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] milojoseph:
Yup, I know Samsung is protecting it's spay and Knox.. But let me blow the fuse. Idc about that stuff give me the option to sign up, like Lg so I can void my warranty to unlock the bootloader. But it's weird that it's the U.S model. I think carriers don't want to deal with customer hassles
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] elliwigy:
doubt it considering its a very small number.. surely those small number complaining to have it unlocked are more than those that would have issues if we had it unlocked lol

Does anyone know why Gear hardware don't work with the U1 fw? Like Gear VR not working. Gear S3 works but SPay disappears on the watch
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] bd1212:
Does flashing the unlocked software disable 4x4 MIMO and 256 QAM or are those still functioning normally?
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] Acoustichayes:
It depends on if your carrier supports it. T-mobile is the only one to support LTE-U, 4x4, and 256 simultaneously on their network currently.

So depending which carrier you flash will probably decide which services get enabled from a carrier update.
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] bd1212:
I'm with T-Mobile, so those features should all be active even though I'm running the unlocked S8 firmware, right?
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] Acoustichayes:
But then I just saw this... Which throws up mixed signals on capabilities
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] Acoustichayes:
That is correct. From my comment above, currently they aren't implementing all the technologies together. Assuming later this year or next year
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] bd1212:
You mean T-Mobile isn't currently implementing all the technologies together? From what I've read it seems to be the opposite, those three network technologies are already implemented and functioning together at certain cell sites. Definitely not all of them, but some. I'll have to run some speed tests around my state and see if I notice slower speeds on the unlocked firmware.

Maybe I'm misunderstanding your post, though.
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] Acoustichayes:
I meant they aren't all working together concurrently.
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] bd1212:
You mean the S8 itself isn't using them concurrently? That doesn't make sense, though. One of the most widely marketed features of the S8 was it's gigabit LTE capabilities by utilizing LTE-Advanced technologies such as the ones that T-Mobile is currently using on it's network. Is there a source other than that screenshot from Samsung's website that talks about this?
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] Acoustichayes:
Once they make it capable to the masses yes. But the full feature set isn't fully implemented yet. They just tested it earlier this year... They still have to upgrade towers and everything else on the network for people to use it. You can't prepare many towers to handle these things within 5 months.

Especially given tmobile is the one that's furthers along in this process. Literally a simple Google search can tell you these things
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] bd1212:
Actually, that's incorrect. I've spoken with a few T-Mo network engineers and they've said that 3x CA, 4x4 MIMO, and 256 QAM are active at many cell sites already. This isn't to say it's active at all of them, but it's definitely already live and available for use by customers in areas where these technologies are active, so the S8 should be able to support that already. Here's an article from September 2016 that states exactly this: click here.

From the article: "According to T-Mobile, its new 4x4 MIMO technology is now available in 319 cities across the country" ... "T-Mobile on Tuesday also announced the launch of 256 QAM for downloads and 64 QAM for uploads. Ray said the technologies are already live in half of the Un-carrier's network and will be live on every T-Mobile cell site in the nation by the end of October."

So, the S8 should certainly be able to take advantage of this right now, not in a few months time.
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] Acoustichayes:
I've already stated I'm talking about all 3 concurrently. LTE-U, 4x4mimo, and 256 .

And tmobile won't have LTE-U running for months still. And given it runs in the 5ghz range, you're going to have to be close to a tower to be able to get those speeds.

Point being, even though the 835 has the x16 chip in it, with a theoretical max of 1gb+/-, you won't see anywhere near that in consumer capabilities.

Look at the s7. Cat 9 lte, capable of 450mb/s, yet actual usage never got near it.

To sum it up, you won't have to worry about maximizing on all of them anyways because you'll never use it in a real world scenario anyways. Given standard lte with CA can get well over 100mb, all the extra stuff is still in the future for necessity
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] bd1212:
Oh yeah I totally realize that gigabit LTE won't ever be the actual speeds we'll see, but the reason I initially asked if the unlocked firmware supported those network technologies is because even here in my hometown they make a big difference to LTE speeds. For example, my iPhone 7 Plus gets about 30Mbps down, but my S8+ (on T-Mo firmware) was hitting 80Mbps. I can only assume it's using CA with either 4x4 MIMO or 256 QAM (pretty sure the towers around me have been upgraded to support both) to achieve those higher speeds.

So, I asked my question because I didn't want to flash the unlocked firmware and then find out 4x4 MIMO and 256 QAM don't work with T-Mo on the unlocked firmware. Thankfully, that doesn't seem to be the case. Those technologies may not mean I'll get full gigabit LTE speeds, but they definitely make a pretty significant difference in everyday speeds.
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] Acoustichayes:
We got way off the initial question then here haha. But yes, they all should be active on all firmwares because they are all part of hardware capabilities and eventually being implemented on every carrier
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] bd1212:
Haha yeah we really did. But yup I get what you were trying to say, was having a brain fart earlier I guess.
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] Zorn_:
Can we get some additional info on some of these steps please?

Does this require using both regular Odin, as well as the Prince modded one, at different times?

Step 15 "open IME setting on Factory Binary" - I don't understand what this means

Do you just start typing adb commands into the command prompt at random as the phone is rebooting and it will send to the phone? Confused about that part.

In step 17 , do you still select XAC if you are planning to use Tmobile?

In step 24, make sure to flash non-home CSC - what does this mean? As in, put nothing in the UMB field, and just use the regular CSC file in the CSC spot in Odin?
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] mweinbach:
It requires both Odins, on the Factory Binary home screen it says IME and you do select XAC because you are just changing your CSC to be able change it with the command and EngBoot. If you follow everything exactly it works. If it seems wrong, it still works.
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] atarilynx:
I just went through this last night...and I figured I would answer your questions: Yes...you need both Odins. Make sure you know which one you are using, since If you attempt to image with the unmodded one the third time you use it, you have to reboot the phone and get it into bootloader again. Once you see a small white line on the screen of the phone...Odin is attempting to image. If you used the unmodded Odin and got a SHA-256 error like I did, the phone is still in receiving mode even though Odin errored. It needs to be put into bootloader mode again and the modded Odin used

the ADB commands will only work when the phone has booted into an image, whether the Factory Binary image or a different one. So wait. And "open terminal" means opening a command prompt in your Windows PC

the Factory Binary image has an IME icon on the bottom. touch it, and you'll get a keypad. That is where you enter the code from the next step.

for the step 24 I flashed the other CSC file in the ROM I downloaded. It had a home_CSC and a CSC_OYN. I flashed the CSC_OYN. If this is wrong, let me know.

I have one question for the community. People talking about having XAA/XAA/XAA or XAA/TMB/TMB, etc. I think I know what it means, but would someone explain that and how I can check what I have on my freshly flashed phone? I have imaged many an android phone, but I am new to Samsung flashing.
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] Zorn_:
Thanks for your answers. This one I can actually help with. If you are on a carrier version, under "About Phone" you will have a field called carrier software version , or something very close to that, which will show this. If you are on the G950U1 unlocked firmware, this doesn't show up at all because there's no carrier software of any kind. But if you were on TMobile firmware for instance, it will appear in there and show TMB/TMB/TMB I believe.
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] atarilynx:
I did some searching...and I discovered this in a different thread...thanks.

"Settings / About phone / Service provider SW ver."

What I am unclear about is what they actually mean.

I have a TMobile S8 that has been unlocked, but only gets HSPA on Cricket/ATT SIMs. That is why I looked at imaging. I followed the steps, but now I have an XAA/XAA/TMB phone.

Which section "unlocks" the many bands of the phone? what do the other two sections mean?
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] ZION959:
Delete
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] Acoustichayes:
All bands of the phone should be active by default if you have a US variant. As they are all the same device. Just check to make sure in the dial pad configuration. Dial *#2263# and it should bring up the menu showing all the active bands on each radio

Did you install the correct drivers and are you using the modified odin?

If you are on download mode Odin should say COM3 or another COM when it detects your phone, then you can proceed loading the files you downloaded.

After many trial and error and frustration, I was finally able to flash G950U1. I didn't do exactly what the guide said but it worked for me. Here are my differences.

1. Guide appears to me I need to prepare Odin before connecting the phone. For me, I have to connect the phone while adding firmware in Odin to get everything rolling.

2. The traditional Bixby+power+volume down didn't work for me (I could use it to enter download mode but always failed in Odin). I used "adb reboot bootloader" to enter download mode and Odin could flash.
[T-Mobile Samsung Galaxy S8 Guides, News, & Discuss] jchl97:
I flashed G950U1 for about 2 weeks and finally received my first OTA update (QDC>QE3). I can now confirm that flashing this firmware will completely transform your carrier device into the unlocked model without any issues thus far. Much pleased that Samsung seems to be working to get updates on the unlocked model much quicker as well!

So did the update to the U1 firmware bring the actual Bixby? When I first updated I pressed the button and it seemed to be true. It did the cool animation and brought up a terms and conditions menu. Now it doesn't work. I go into Bixby home in the "about Bixby" menu to update it but when I press update, it "downloads" for like 2 seconds then stops and says latest version installed but nothing changes

"UPDATE: Chainfire says that we might have Engboot root at some point, but for now, it is very restrictive. " The last part confused me.

Does that mean flashing this Engboot does have enough root... say for at least Titanium Backup or GMD gesture control (both require root) to work properly??
