I've read every step and disclaimer, downloaded all of the files, and trying to take a T-Mobile unlocked device to AT&T to get Visual Voicemail and a couple other things to work properly (sometimes data switches and stays on HSPA+ not LTE until I mess with APN settings).

Anyways, I have all the files and started with the Odin steps to put in the Factory Binary file but everytime it says Setup Connection.. then after a while

<ID:0/003> Complete(Write) operation failed.

<OSM> All threads completed. (succeed 0 / failed 1)

I'm using the file: COMBINATION_FA70_G950USQU1AQCF_CL11021239_QB13008157_REV00_user_mid_noship_MULTI_CERT.tar.md5\COMBINATION_FA70_G950USQU1AQCF_CL11021239_QB13008157_REV00_user_mid_noship_MULTI_CERT.tar.md5

in the AP slot like it says to do.

Anything I should be checking for? I did everything for the Odin and config file. Extracted folders to the same spot on my desktop. Have my S8 at the teal Downloading... page connected with Samsung USB drivers installed.

Is it possible to flash a CSC (GLB to be exact) that sold the exynos variant to a snapdragon unit?
[Samsung Galaxy S8 Guides, News, & Discussion] :
Need some help. I have an S8+ model SM-G955U1. I want to change it to cricket firmware. I changed the CSC to AIO in factory binary, and it says AIO in bootloader now.

Only thing is I downloaded the AIO firmware and it doesn't seem to have any user data file for carrier specific boot screen and apps. Anyone flash to cricket from another model?
[Samsung Galaxy S8 Guides, News, & Discussion] thao87:
I have one big question. If my Samsung S8+ is a T-Mobile Brand which is pay for and unlocked, i can flash verizon firmware and it will work with verizon? from what i heard the Tmobile version have all the lte bands but does not have the CDMA for making calls /activating the phone. Can anyone verify if this is true.

A Verizon S8+ can swap to tmobile no problem because it has both cdma+gsm ... this is what i think ... but can someone shed some light?
[Samsung Galaxy S8 Guides, News, & Discussion] Thor2j:
All s8 and s8+ are the exact same hardware wise.
[Samsung Galaxy S8 Guides, News, & Discussion] DSTG:
Hey all, so I just read this entire thing but wanted to ask some questions, especially now that it's been a few months since this thread has been really active with the updates. I have an AT&T 950U that they unlocked for me because I am now in Germany for Army stuff. I'm bouncing between a few sim cards to see what I like best, but it seems I'll be going with T-Mobile Europe. As has already been said and asked about, the phone does not receive updates because it's off the AT&T tit. How to update is what got me here. So here's what I've gathered.

I can flash pretty much any US S8 firmware on it, including 950U1 FW.

On 950U1 firmware, I won't have AT&T features, which right now doesn't matter until I'm back in US later next year..

On 950U1 firmware, updates SHOULD come directly from Samsung

I CAN put T-Mobile Firmware, and in theory (as I'm on EU T-mobile) get updates through T-mobile.

My questions are

Has anyone else happened to be in this position and know if T-Mobile EU will push updates to my phone? I'm not sure what model S8 gets used around here.

Once I'm back in the United States, is it really as simple as flashing AT&T FW again and it's all back to norm like I never left?

I am currently on G950USQU1AQGL, which seems is a little newer than the FW I have seen posted here. If I flash the older t-mobile, and it DOES take, it ought to update to the newest OTA automaticaly right? If I put 950U1 firmware on there, should do the same directly from samsung right? Or does the last "ATT" being hardwired prevent updates from happening this way?

I caught onto there being way to completely backup the phone in this thread in case the updates don't work and I want to put it back to how it is now, with ADB. I'll look into how to do this, but before I do I just wanted to ask if this backup restores every aspect like CSC, firmware, and anything else that is changed in OP process, as if it was never attempted?

I want to be able to come back to the states and jump back in with AT&T. I don't really care to change this or that, but I would like to make sure I get updates, so if I can just flash an update after QGL without having to worry about carriers and unlocks and whatnot, it would be preferred. So if anyone has managed to find a place or method to do this that'd be great if you could point me in the right direction.

Thanks a lot for any help you can give me fellas. Have a great day.
[Samsung Galaxy S8 Guides, News, & Discussion] yahoo_test:
Say I get unlock code from Xfinity Mobile, flash with AT&T firmware to take advantage VoLTE, can I use this phone on other GSM network(out-of-country, assuming bandwidth match), flash with AT&T firmware doesn't mean I am locked to AT&T network, is that the correct assumption?
[Samsung Galaxy S8 Guides, News, & Discussion] Thor2j:
You will not be locked to att firmware but volte functionality on another carrier will be iffy.

[Samsung Galaxy S8 Guides, News, & Discussion] thao87:
it is the same but it will not activate on SPRINT/VERIZON if you are switching from a TMOBILE/ATT Brand even though the bands work.... the activations process will not work in store. etc....
[Samsung Galaxy S8 Guides, News, & Discussion] thekojac:
I'm very confused from this whole carrier switching thing (coming from a S7).

I have a Verizon S8 that I would like to use the unlocked U1 firmware on. I don't care about carrier features or anything like that... plain old unlocked firmware is fine.

Can I just flash the U1 firmware directly, skipping the carrier switching part?

What about if I want to switch back to the Verizon firmware (with all the bloatware and carrier features) from the U1 firmware? Can I just flash the Verizon U firmware directly (like I used to do on my S7) or do I need to follow the carrier switching instructions?
[Samsung Galaxy S8 Guides, News, & Discussion] wkorniot:
I have a S8 with model number SM-G950U. I purchased it used and it has been unlocked already. The original owner originally purchased it from Sprint so it has Sprint bloatware and the Sprint loading screen. I'd like to get rid of these but I'm not sure about the unlocked firmware version this guide provides a link to. It's labeled SM-G950U1. Will that work fine with my Sprint so that's been unlocked?
[Samsung Galaxy S8 Guides, News, & Discussion] rlsyoung:
Can I just flash the Verizon firmware onto ATT S8 without following other steps? Will the Verizon radios work, or do I need to follow carrier switching (I do not want to flash the unlocked firmware).
[Samsung Galaxy S8 Guides, News, & Discussion] Analyzer52:
I was getting ready to go through this whole process to change a Verizon S8 to a Sprint S8 but as it went through the activation process with Sprint it did it automatically. The boot logo changed from Verizon to Sprint and everything after it finished downloading the OTA updates. Just letting anyone else know that maybe in the same situation. This would still be necessary if you wanted the unlocked bloat free version instead. All features work and there are signs of the phone ever being Verizon at this point.
[Samsung Galaxy S8 Guides, News, & Discussion] harshshah0589:
Follow these steps : (Copied from 1st page of this thread but I have provided link to latest XAA firmware)

NOTE: The unlocked firmware does NOT unlock your phone for use on other carriers, it only removes bloatware. Some carrier specific features, such as Wi-Fi Calling and VOLTE will not work with the Unlocked Firmware.

Prerequisites:

Prince Comsy version of Odin : https://www.androidfilehost.com/?fid=24591023225177749

Unlocked Firmware : http://updato.com/firmware-archive-select-model?record=422E5AAFD55111E7A5F9FA163EE8F90B

Steps:

1) Extract the Prince Comsy version of Odin and the Unlocked Firmware you downloaded from below.

2) Turn off your S8.

3) Once off, hold the Power button, Volume Down button, and the Bixby button until you see a blue screen on your phone.

4) Press the Volume Up key to enter Download Mode.

5) On your PC, navigate to your extracted Prince Comsy Odin folder.

6) Double click on the "Odin PrinceComsy" executable (Odin PrinceComsy.exe).

7) Connect your phone to your PC with your USB cable.

8) You should see PrinceComsy's Odin output "Added!!" in the "Log" tab and underneath the "ID:COM" section, you should see an empty box turn blue.

9) Now it's time to add your firmware files that were extracted earlier. Individually add an appropriate firmware file for each box on the right. The "BL" box will require a firmware file that starts with "BL", the "AP" box will require a firmware file that starts with "AP", the "CP" box will require a firmware file that starts with "CP", and the "CSC" box will require a firmware file that starts with "CSC" (DO NOT USE THE "HOME_CSC" file for the "CSC" box).

10) Go to the "Options" tab and make sure that only "Auto Reboot" and "F. Reset Time" are checked/ticked.

11) Go back to the "Log" tab.

12) Click the "Start" button on bottom right.

13) Sit back and relax for a while. Odin will output what is being flashed in the "Log" and on a box in the top left.

14) The box in the top left will become green and in black letters say "PASS" once the flash was successful.

15) Once the flash finished, disconnect your phone from your computer.

16) Your phone will do an erase at this point, so don't mess with your phone until you reach the setup screen.

17) PROFIT. CONTINUE WITH THE SETUP ON YOUR PHONE AND ENJOY!

I just did this on my unlocked T-mobile S8 and it worked fine. Device status is still 'official' and Samsung Pay also works fine.
[Samsung Galaxy S8 Guides, News, & Discussion] rlsyoung:
Will this work for me going from ATT to Verizon? I want to use Verizon firmware, so I do I just replace unlocked firmware with Verizon firmware, in this guide?
[Samsung Galaxy S8 Guides, News, & Discussion] wkorniot:
I did this last week on my Sprint Galaxy S7 that I have unlocked and am using on MetroPCS. It worked perfectly and I even thought I didn't have to redo all my customizations I had on my phone but when the phone restarted after flashing I got an error (I can't remember exactly what it said) but some background process had stopped working and Everytime I clicked ok on the warning it would immediately popup again making the phone unusable. I was forced to turn it off and boot it up into maintenance mode or whatever it's called and do a factory reset. After that the phone worked perfectly with no errors. All I had to do was basically start from scratch on my settings and customizations.

Another note is that I did end up having to do about 5 or 6 over the air system updates to bring the unlocked firmware up to date.

Hi everyone. First off, thanks to everyone who makes these things possible. Those of us tech-dummies are forever grateful for all your work.

But, I can't get it to work. I've tried following these instructions, but, I can't get past Step 13 of the "Carrier Switching" process. I edited the Odin3 file to switch to "UMS/PATCH=1"

I have downloaded all the attached and appropriate files. I've put my phone into download mode, where the phone screen says "Downloading...Do not turn off target." When I plug it, Odin gets a blue box and the message "Added!" I add the file that starts with "Combination" after clicking on the "AP" box.

But, when I click "Start," Odin fails. Here what the log says:

<ID:0/004> Added!!

I would recommend flashing back BQK5

https://xdaforums.com/verizon-galaxy-s8/how-to/firmware-g950uoyn2bqk5-t3717845

because right now we can't get a second bootloader factory binary for the s8

On BQK5 samsung updated their bootloader to bootloader 2. You can't go back to any bootloader 1 builds.

Same problem on s8 , if some one make factory binary for bootloader v.2, then it will be possible.

When flashing ATT firmware, does anyone know where to get the USERDATA? Do you leave it blank? I found an old ATT USERDATA, but the newer ROMs on updato don't have the ATT USERDATA. Also, does anyone know if I want to run the latest stock ATT firmware post BL2 on an unbranded phone, do I want to update the boot loader first and then use ODIN to flash ATT firmware or can I just go from BL1->BL2 during a flash of the ATT firmware?
[Samsung Galaxy S8 Guides, News, & Discussion] vshvash88:
Thanks for the response. I actually haven't flashed anything into the phone yet, it's completely stock.

Just to clarify: I should flash the BQK5, and then follow the steps to flash the T Mobile firmware into it?
[Samsung Galaxy S8 Guides, News, & Discussion] nfremd:
Hey there everyone, I have an unlocked S8 (SM-G950U1) and am considering switching to the T-Mobile firmware (SM-G950U). Few reasons I'm considering it (but happy to be talked off the ledge), A) I'm wanting to use DIGITS and the T-Mobile firmware has multi-line built into it and the unlocked doesn't B)the 4X4 MIMO.

I'm not looking forward to losing the caller id being baked in and the lack of bloatware, but luckily T-Mobile doesn't have a ton of it that I don't already use.

If anyone can help hold my hand I would appreciate it, I've done plenty of flashing kernels/roms on Nexus/Oneplus phones, but with those phones you can easily recover if you screw something up. I'm more worried with Samsung because I don't have TWRP to fall back on and I don't want to lose Samsung Pay.

Any help is appreciated. I'm currently on Beta 4 (Oreo) but would downgrade to G950U1UEU2AQK2 and then look to move over to G950USQU2BQK5. The questions I have are A) I'm US, so why would I download canadian firmware? I'm already using Tmobile, but on an unlocked S8, so I still need to switch a carrier? B)I could easily move back to the unlocked firmware since that was the original firmware on the phone correct?
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
You're most likely on Bootloader v2, since you have Oreo Beta 4. Right now, I don't have the Factory Binary for that bootloader version; therefore, you can't follow the "Carrier Switching" section (yet). If you were to follow the "Carrier Switching" section on a phone with Bootloader v2, then Odin will report a fail, as you're trying to flash a Bootloader v1 Factory Binary onto a phone with a higher bootloader version, which Samsung prevents, meaning that Bootloader downgrading is impossible.

The "HOME_CSC" file found in the Canadian firmware is flashed with Odin onto your phone, allowing you to select the "XAC" CSC code in the Factory Binary, which allows rw permissions to the "mps_code.dat" file (which is otherwise normally locked), and would allow you to input a different CSC code of your choosing, with ADB.

And yes, you can always move back to unlocked firmware, in the event you flashed another carrier's firmware. All you would have to do is follow the "Carrier Switching" section to change your CSC code back to "XAA," which is the unlocked firmware CSC code, and then follow the "Flashing Standard Firmware" section.

If none of this makes sense to you, please let me know; I can understand that this is a lot information being thrown at you.
[Samsung Galaxy S8 Guides, News, & Discussion] nfremd:
Thanks for taking the time to get back to me. No that makes sense, I was wondering if I was on bootloader v2. How would I be able to confirm that I am? Go into download mode? Also, I would first downgrade from 8.0 beta to 7.0 stable before doing any of this. When I downgrade, that won't move me back to v1 bootloader right? If it won't, i'm basically screwed until we get a v2 bootloader we can use huh? Do we have any idea when we might, or how we could get one?

Verizon S8+ need help!

I have a verizon s8+ running the unlocked U.S version. Every time i try to flash back to stock verizon software, it reboots right back up too the U.s unlocked version. The phone is on QK5 and also unlocked on verizon through ebay but everytime i pop a metropcs sim card into the phone it dont work cant get data or anything working on it. I also think its on bootloader 2 because everytime i try your method to carrier switch, when i put in the combination file into AP it fails and reads binary fuse>2. Need help trying to get this phone working on verizon, I get no data on the u.s verision or verizon software still shows emergency calls only.
[Samsung Galaxy S8 Guides, News, & Discussion] bernardwu:
hello! I have a SM-G950U (unlocked, originally was Sprint). I'm thinking of flashing a more updated unlocked firmware for my phone however I couldn't find any XAA G950U firmwares, only XAA G950U1 firmwares. If I follow the steps for "Flashing Unlocked Firmware" and use XAA G950U1 on my G950U, will it damage my phone in anyway or is it 100% safe?

Also if it does indeed work, will my phone model in the settings change from SM-G950U to SM-G950U1?

This is 100% safe and is completely reversible (by following the "Flashing Standard Firmware" section)! And yes, your model number will change from 'SM-G950U' to 'SM-G950U1' if you follow the "Flashing Unlocked Firmware" section of the guide.

Hi Mike15678, thank you very much for posting this guide! I am trying to flash the Verizon firmware onto an SM-G950U1. I ran into a similar problem as an earlier commenter, which is that when I downloaded the 12/27/17 Verizon firmware from Updato it contained every file except for the userdata file. The other commenter was able to get the userdata file by retrying the download; however, I have been unable to get the userdata file in any of my download attempts. I also tried downloading an earlier firmware version but had the same problem. Do you know if there's away to resolve this or another place I could get the userdata file? Thanks!
[Samsung Galaxy S8 Guides, News, & Discussion] shellshocker528:
I figured out the problem: I was downloading the SM-G950U1 Verizon firmware, which is unlocked and does not contain the userdata file. To get the userdata file I needed to download the SM-G950U Verizon firmware, which is carrier-locked. Thought I'd clear that up! Thanks again for a great guide!
