Did you change sim cards to get everything working? I can't change firmware but will have either on T-MOBILE no data or network. On Verizon I can make and recieve calls and text but no internet data. Im on Boost want to change to Verizon or T-MOBILE. For either carriers features. Had given up but back at it. Thanks
[Samsung Galaxy S8 Guides, News, & Discussion] uwapalwa:
Just use 3 steps

1. Download firmware u want

2. Download odin prince comsey

3. Flash

Kk. That's how simple it was on my s7edge. But do I need to change any settings to get everything working?(data, phone calls, internet)
[Samsung Galaxy S8 Guides, News, & Discussion] uwapalwa:
Are you changing carriers? And is your phone unlocked

No not switching carriers just want Verizon features. Still on Boost plan. And no it's not carrier unlocked

well dont expect ppl to go searching for you or your other posts to help u.. ppl cant even search for themselves letalone search for your posts just to get details then search for you for a solution

i wasnt telling u to root ur phone.. i was saying if u had root this method is easier and will work.. i nvr got this to work either
[Samsung Galaxy S8 Guides, News, & Discussion] GrandMstrBud:
LOL I've tried everything trust me this isnt my first phone. 3 different computers, downloaded it to many times to count, modified and different Odin versions, different USB cables, the list goes on. Probably going to either get rid of Verizon or sell it on Swappa and get the VZW version. On vacation now so I can't sell it but really debating getting g rid of it and the service.
[Samsung Galaxy S8 Guides, News, & Discussion] vo_danh:
So from my understanding. I have an S8 unlocked. It's model is SM-950U1. I can download the 950U tar and switch back and forth between :

VZW Verizon or back to what is is now (XAA Unlocked US)?

So that 950U.tar has all the versions in it? Does this mean whoever releases Oreo first, verizon or samsung for the unlocked, I could load it into my SM-950U1 ??

i'm a little confused because I thought we had to have an unlocked boot loader to be able to load in firmware. My main motivation is the lack of wifi calling and even normal cloud support from verizon when on unlocked (cloud only saves contact list instead of everything else too).
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
you are the first person ive ever heard who prefers vzw cloud over samsung haha
[Samsung Galaxy S8 Guides, News, & Discussion] rudeguy:

I have a US Cellular S8+ I'm trying to work with. I downloaded the 955W firmware as specified in the OP. When I go to flash it in Odin, I get the error "SHA256 is invalid". Just to be sure....I'm supposed to be using the W firmware and not the US Cellular firmware for the first step, correct?
[Samsung Galaxy S8 Guides, News, & Discussion] vo_danh:
Well its the first time I've used a samsung. But now wifi calling and 3g are a bigger concern. This says it 'll work on the 950U, will it work on the 950U1 ? Is that the same thing?

hi can someone please help me? im on an unlocked at&t s8 plus, using t-mobile service. i want to use this method to switch to t-mobile firmware but reading thru this thread people are saying i dont have to go thru all the steps listed. What do i do to flash t-mobile firmware & what firmware do i download. I also have root, will i lose root & have to re root?
[Samsung Galaxy S8 Guides, News, & Discussion] sjhotwings:
1st does your phone has to be unlocked to do this , 2nd after succeeded switching to a different carrier can you use unlock service to unlock it?. anyone succeeded doing this on the sprint version of the s8
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
this does not automagically unlock your phone.. you need to unlock via the usual methods such as your carrier you purchased the device from..

you can switch carriers using this method but it will not unlock the phone, youll just basically be changing the boot animation and bloatware etc..

so if your locked to tmo on a tmo device and you switch to say att, youll still be locked to tmo but would have att bloat/boot animation so i dont see the point unless youre already sim unlocked

another example, i have verizon which comes sim unlocked so i can switch to any carrier and it will just work on any carrier bcuz its already unlocked at the factory

---------- Post added at 07:32 AM ---------- Previous post was at 07:29 AM ----------

you can download latest TMB AQHD firmware.. extract the system.img, flash in ff followed by a systemroot.zip then flash cp and csc and TMB userdata in odin afterwards

theres a few more steps to it but u get the idea.. if u followed sampwnd root follow part 2 instructions but use the system.img of your choice then modem n csc files in odin after

[Samsung Galaxy S8 Guides, News, & Discussion] Nexii5:
Sorry for the late reply!

When this happened to me I was able to reboot the phone doing the bixby+power+volume down trick and it started the setup procedure but it was messed up. Meaning it was the setup process but it bypassed a bunch of steps and setup quickly, but wrong. What I did was just let it do it's thing and then do a system restore. Once it restored everything was working properly and the setup process went smoothly.

I followed the entire instruction converting my Verizon galaxy s8+ to T-Mobile, now I downloaded the "Phone NFO" app to verify the CSC code, the Original CSC code is empty

I am not looking for anything fancy. I just really want AT&T stock on my Verizon phone with all features (VoLTE, VR etc) working.

Once I get to step 15 I keep getting the error "process.com.android.phone has stopped". I click OK and proceed to IME and enter in the numbers even though the error pops up every couple seconds. Once it gets to the screen to select XAC, before I can even select anything it automatically reverts me back to the home page. Anyone else run into this issue?

13. Put the HOME_CSC of the G950W firmware into the CSC part of Odin 3.12.7 (NOT PrinceComsy)

14. Click start

15. Open IME setting on Factory Binary

16. Type in *#243203855#

17. Select XAC

****NOTE ABOUT 15-17: A bunch of system processes kept saying they were force closing, but I just kept saying OK until I could successfully type the code into the dialer and select XAC. It worked, even with those processes supposedly failing.****
[Samsung Galaxy S8 Guides, News, & Discussion] Billyst3:
Sending out an S.O.S.......to this world.

Hello all. I'll get the apology out of the way now. The next (first few) post from me will be in effort to correct an issue. I thought I was good with phones. I do love them, not so much for talking lol but because of ALL of the stuff you can do with them. Ever since my 1st android, (still one of my all time favs) my sprint OG HTC Evo, I've loved android. Yeah, I have a piss on Apple sticker lol.

Okay enough meaningless talk.

I have my note 8, so have freed up not s8 plus. Both are at&t. I paid $25 to have an unlock code sent to me. It worked, at least is said success. I then put in a Verizon SIM and I got nothing. I know cdma or gsm or cdma/gsm network phones don't combine well, but i was under the impression that this could be overcome easily??? If so I am unable to make it happen...

In short I think after reading all day, that I've found the 1 solution; the directions in this post?

What I want to be able to do is 1) use the phone on AT&T, 2) use it on ANY U.S. network 3) have it as stock as my note 8 I purchased from Samsung, Factory UNLOCKED.

Is this possible and can it be done by a tech savvy, but no expert guy that can follow instructions?

I'd also like to be able to go over seas and use it as well.

Again, I apologize for the help request off the top, but I'm in frustrated mode at this point. My $25 bucks basically did nothing for me.

Oh p.s. my s8+ is model G55U according to the sticker on the back of it.

Thanks to all in advance!:D

I look forward to learning lots of good stuff.

Bill

[Samsung Galaxy S8 Guides, News, & Discussion] sharper4:
I just want to say thank you. Been driving me crazy having an ATT phone on TMB and not being able to have all my features working. For some reason, the downloaded firmware I first got didn't have the AP file, so I was stuck waiting for another download to finish but the instructions and info here were very helpful. It says TMB/TMB/ATT, but I don't think that's causing any problems with anything. WiFi calling and everything else is now fully functioning.

Side note, I missed the cutoff for the Oreo beta. Didn't qualify with the "ATT" phone but didn't get switched to TMB before they quit taking testers. Still thankful to this group.
[Samsung Galaxy S8 Guides, News, & Discussion] kennyhayes:
Thank you so much to the contributors of this guide and the answers in the forum. I was able to switch the firmware from Sprint to T-Mobile successfully on my Galaxy s8+. I do have a quick question, when I go into the settings it tells me that my service provider is TMB/TMB/SPR. What is the last spot referring to? Is it possible to change it to TMB or is that the only one that is permanent? Thank you!

---------- Post added at 09:36 PM ---------- Previous post was at 09:33 PM ----------

This was exactly what happened to me. I had Sprint firmware on a T-Mobile SIM card and I didn't think it would be an issue. It's too late now for me to get the beta. I have been waiting months for Oreo but the wait will have to be a bit longer I suppose:(.
[Samsung Galaxy S8 Guides, News, & Discussion] muppetmaster916:
Orrrr just flash to QGL. Then apply oreo beta from stock recovery. Super simple. As long as you're familiar with odin. Any us variant s8/s8+ can run the beta right now
[Samsung Galaxy S8 Guides, News, & Discussion] kennyhayes:
So sorry, but what do you mean by QGL? Also, do you know if anyone has grabbed the Oreo firmware and where I could find it? I haven't seen it anywhere :(
[Samsung Galaxy S8 Guides, News, & Discussion] mweinbach:
PSA: If you want Oreo but could sign up, download this firmware: http://updato.com/firmware-archive-select-model?record=FBDD1D148EB711E7963AFA163EE8F90B. Flash it with odin, home_csc if you want to keep your data. Then download the ota.zip from the ATT forums and use recovery to flash it. You are now on Oreo.

[Samsung Galaxy S8 Guides, News, & Discussion] sharper4:
So, when we flashed the first time we had to flash 4 files (BL, AP, CSC, etc). This time, we simply flash the HOME_CSC file and it will keep our data but upgrade to Oreo? This seems easy enough.

Followup, does anyone have the a link to the OTA.ZIP? I did a quick search but it came back with a lot of irrelevant info. If anyone on non-ATT has used it, does it put anything ATT related on our phone or did you stay exclusively TMO, or Sprint, or whatever you have?

Thank you mweinbach. I'm pretty excited about upgrading (esp if it doesn't require all the steps it did when I first flashed from ATT to TMO because I had to re-install everything from scratch).

Ok here's a quick question for you experts out there!

I've just bought a USA unlocked (U1) S8 for use in NZ. Now the phone works fine (aside from the obvious lack of updates), but my carrier (2 Degrees) has just launched Wi-Fi calling, but I have no option for this under call settings being an unlocked USA phone. Is it possible to enable this feature, or am I out of luck? Local S8's have Exynos chips whereas my S8 is the Snapdagon variant. Am I right in thinking it would not be possible to flash an NZC CSC file meant for the 950F phone to a 950U1 device?

Thanks for any advice ?

Why wouldn't it? Even if you flash a different firmware, if the device is sim locked, there is no point unless you want the bloat from other carriers which would probably be useless for Sprint users or they want to use the unlocked firmware but they're still sim locked to Sprint.

Yes so then this thread is for those wanting to change carrier firmware and would have nothing to do with a simlocked phone if you don't have any need to do so. Why go into a thread that has nothing to do with you? Can you not unlock a Sprint phone? All carriers have simlock. Etc etc.

Galaxy S8 (Snapdragon) bootloader unlock via carrier change - is it possible?

Just few "loud" thoughts...

From what I read the last hour, it's clear that the main problem with the ROOT is coming from the locked bootloader.

The lock is in place for the carrier provided devices only, since the International versions has the "OEM Unlock" option available in the "Developer Options".

As I understood the carrier's code role, that's a possible way to convert a phone, let say from Canadian Rogers (code RWC) to Canadian Public Mobile (code XAC), in using the EngBoot and after that flashing the full set of XAC files (where the bootloader will be replaced via Odin's "Phone Bootloader Update" switch).

Such a phone should work fine with any provider and the only drawback is that there will be no OTA updates.

Please, correct me if I'm missing something!
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
You'll still get OTA updates, just slower than carrier provided ones.
