Thanks,

Question, I need make all process or only the unlocked U1 firmware install, I mean, i don't need make the carrier process?
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
Just u1 will do it
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
No problem, but what do you mean by losing your data?
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
Just follow what [MENTION=2479447]bricky23[/MENTION] said, unless you are going to be using an other carrier. If that's the case, make sure your phone is SIM unlocked and change the CSC code to "XAA" (U.S. Unlocked) by following the "Carrier Switching" section. Then flash the unlocked firmware by following the "Flashing Unlocked Firmware" section and insert a SIM card of your choice.
[Samsung Galaxy S8 Guides, News, & Discussion] keithnet:
When T-Mobile/Samsung release a new firmware and I follow the "Flashing Standard Firmware" instructions, will it delete the phone's data or just update the system software?

-Keith
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
Following the "Flashing Standard Firmware" section will delete everything on your phone. Try doing OTA updates instead.
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
Check the introduction if you are willing to do this. Could someone tell me if flashing stock firmware on an unlocked S8 (FROM THE FACTORY) with standard Odin, gives you a fail? Possibly a "Model dismatch fail"? If so, I'll have to edit the guide. [MENTION=3664806]nocloo[/MENTION], did you successfully flash stock on your unlocked S8 with standard Odin?
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
[MENTION=712470]keithnet[/MENTION] You can follow the "Flashing Standard Firmware" section, but for Step 9, use the "HOME_CSC" file for the "CSC" box instead of using the "CSC" file and don't use the "USERDATA" file for the "UMS" box. Disregard the warning, as that's only for people who need to flash regularly (aka Erase-Flash).

I asked peterjitg if he could add the AT&T firmware on fw.updato.com.
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
I'm going to start adding the things I respond back to people, by tomorrow, such as Updating the S8 through Odin and more warnings. I will also cleanup the guide a bit, to make it more clearer. I still need someone to try flashing carrier firmware on an unlocked S8 phone (ONE THAT IS SM-G950U1 FROM THE FACTORY); If you are willing to do this, check the introduction first.
[Samsung Galaxy S8 Guides, News, & Discussion] nocloo:
Yes, the flashing of stock Verizon firmware went fine on my unlocked S8 with standard odin 3.12.7. Thank you for the great guide !
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
Thank you for your info, and I am grateful that you found this guide useful.
[Samsung Galaxy S8 Guides, News, & Discussion] strikerxtreme4u:
I've tried with stock ATT, but there was no USERDATA file, so I used the HOME_CSC file instead. That resulted in a "Model dismatch fail"
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
Where did you get the AT&T firmware from?

[MENTION=8364454]strikerxtreme4u[/MENTION]

I also need a screenshot of Odin once it fails the flash.
[Samsung Galaxy S8 Guides, News, & Discussion] strikerxtreme4u:
Ah I'm an idiot, was using the U1 firmware. Should have payed closer attention, apologies.
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
lol, It's ok we all make mistakes. You got me worried a bit.
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
Wait, I don't understand how it could fail? You were flashing the unlocked firmware on an unlocked S8, correct? The Unlocked firmware doesn't contain a "USERDATA" file.
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
Oh wait, did you put the "HOME_CSC" file in the "UMS" box? That doesn't work.
[Samsung Galaxy S8 Guides, News, & Discussion] TylerG518:
I downloaded the stock TMobile firmware for my Verizon S8... did everything EXACTLY as specified and once the phone rebooted after odin saying pass.. it was still on the Verizon Firmware... am I missing something here?

[UPDATE: So after going through the setup ( I skipped basically everything ) I noticed that in the app drawer and I have stock verizon apps AND stock T-Mobile apps... but the phone is still Verizon's firmware...... where in the world did I go wrong for this to happen?? :eek::eek::eek:
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
Did you change the CSC code to "TMB" by following the "Carrier Switching" section and did you flash the "USERDATA" file in the "UMS" box (including the other necessary files as stated in the "Flashing Standard Firmware" section)? Basically, I'm asking if you followed the "Carrier Switching" section and then followed the "Flashing Standard" section. Did you also follow the "Prerequisites for anything you decide to do in this guide (Required)" section?
[Samsung Galaxy S8 Guides, News, & Discussion] Mike15678:
[MENTION=8362254]TylerG518[/MENTION] Did I correctly answer your question?

I never tried, I was too afraid of coding my warranty. I'm currently selling my S8 to get a OnePlus 6T.
[Samsung Galaxy S8 Guides, News, & Discussion] dreamer8ful:
Thanks for the guide.

Being a noob, I have few questions.

1. Does this guide mean for upgrading from android 7 to 8?

2. If yes, what should I do if I can't find firmware with v8 for my G950u XAA? Can I use v8 firmware from any carrier and flash it using 'carrier switching' guide above?

Sorry for my bad English, hope you understand what I meant. Thank you
[Samsung Galaxy S8 Guides, News, & Discussion] woofersus:
I've been searching around and I'm ready to do this but I just want to make sure I have the right files. I have an unlocked (att) s8 that I bought refurbished. Baseband is g950uqu5crg3 and it's running Android 8.0.0. Service Provider shows ATT/ATT/ATT. I want to flash to XAA and use on Verizon.

I downloaded the patched Odin 3.13.1 software, binary (combination) G950USQU5ARG4, Firmware G950U1UEU5CRJ2, and installed ADB + fastboot (thanks Snoop05) as well as the samsungg usb drivers. Are those files correct? From there I basically follow the instructions for switching carriers, not the ones for installing an unlocked firmware, right? I had no trouble finding the files I was looking for, but it's less clear which ones I should be looking for. ;)

Flashing Successful But NO MORE THAN 1 BAND ACTIVE

Greetings,

Got My Sprint S8 with Boost mobile FMW including BOOTLOADER 5 (NOT 1 OR 2).

1. I live overseas and worked perfectly with local carriers. Switched between 2g/3g/lte automatically and made calls/sms etc. The only issue that annoyed me was Sprint's SIM registration procedure after rebooting and decided to try this thread.

Result:

XAA>UNLOCKED FMW - stuck on 3g single band only and periodically lost singnal

VZW>VERIZON FMW - stuck on 3g single band only and periodically lost singnal + no bloatware at all.

TMB>TMOBILE FMW - stuck on 4g single band not loosing signal at all + no bloatware at all except 3 and 2 of them can be uninstalled.

2. Why Verizon, ATT and Unlocked firmware starts all with G950U1? in fact software that I downloaded as unlocked and Verizon are both IDENTICAL. T-Mobile starts with single U only.

Because of this, I suspect flashing ATT software wont help me at all. Any Help, much appreciated.

[Samsung Galaxy S8 Guides, News, & Discussion] AhmedKhan123:
I flashed U1 firmware on my G955U. Now when I reverted back to stock G955U firmware, it shows me XAA/XAA/SPR. I want to get it to SPR/SPR/ SPR. I've flashed stock firmware multiple times but each time without USERDATA as i don't want any Sprint bloatware or bootanimation. Is there any way to get SPR/SPR/SPR without getting bloatware?

Thanks in advance.
[Samsung Galaxy S8 Guides, News, & Discussion] njdan30:
Wouldn't spr/spr/spr be all sprint? I thought xaa was unlocked or unbranded without the sprint bloat? I have an unlocked sprint model looking to change to unlocked-unbranded myself im also using v5 bootloader
[Samsung Galaxy S8 Guides, News, & Discussion] cnewsgrp:
I have a AT&T S8 (SM-G950U ) with V5 Bootloader. I tried carrier change using the guide and was not successful - would fail at IME setting on Factory Binary. I gave up and installed latest Tmobile firmware for SM-G950U downloaded from sammobile (G950USQU5CRK1) to my pleasant surprise I find that Wifi Calling etc works fine. You need to have TMobile SIM in the phone when you flash the firmware. I am not an expert but please check out (at your own risk)

THX to the OP and supporters around here !

I installed G950FXXU3CRGH_CL14023573_QB19093103. Now my CSC is: XEU/XEU/MOB

Can I use any combination File starting with G950FXXU3 or must it be more specific ?

What is the least / minimum requirement that must fit?

- like must only the bootloaderversion fit XXU3 ?

- or must it be Oreo or could it be from Nougat too (I am on Oreo)

- must the country fit like I am ATO (Austria) but the only available is Germany which has the same LTE Bands
[Samsung Galaxy S8 Guides, News, & Discussion] gggg:
OK, I found that every combination firmware can be used aslong as it has the same bootloader as the original firmware that was installed before.

I switchted to ATO. which is open Austria.

Now it shows ATO/ATO/MOB. So still locked to MOB (A1 Austria)

Of course I also read that this guide regarding carrier swiching does not remove the lock of my carrier ...

So my question is: Is there a way to remove the carrier lock without rooting except unlock codes ?
[Samsung Galaxy S8 Guides, News, & Discussion] fallen_jedi:
I just got my S8 today and read the original post along with the first 10 pages but just want to confirm what I'm about to do is correct as from the guide I can not tell what bootloader version I have.

This is what my phone shows.

Model: SM-G950U

Carrier: Verizon (USA)

Android: 8.0.0

Baseband Version: G950USQS5CSB1

Kernel: 4.4.78

Build: R16NW.G950USQS5CSB1

Knox Version: 3.0 (API Level 24, TIMA 3.3.0)

Android Security: FEB 1, 2019

What I want to do is install the Unlocked Firmware (Bootloader v1), **I THINK** in order to be able to use the moblie hotspot feature on the phone via the verizon network which the phone is from.

So reading the guide I do the following:

1) Download the Samsung USB Drivers

2) Download Prince Comsy's Odin

3) Download Unlocked Firmware (Bootloader v1) ????? I am not sure if I have v1 or v2???

4) Follow the steps in "Flashing Unlocked Firmware:"

Is this correct?

Thanks!
[Samsung Galaxy S8 Guides, News, & Discussion] fallen_jedi:

[Samsung Galaxy S8 Guides, News, & Discussion] phillysdon04:
Thanks!

I purchased an unlocked S8 online but I couldn't get past the Knox Enterprise Cloud Services login screen. I normally setup the phones before inserting the SIM card but this time I inserted an ATT SIM card while on the setup screen. The model number on the phone is SM-G950U and it's 64 GB. After doing all the prerequisites, I then tried the Prince Comsy's Odin but that failed so I rebooted the phone and used the Standard Odin with success. I used http://fw.updato.com to find the latest firmware by searching for SM-G950U1 and I used region code XAA Unlocked US. I didn't want to register for an Updato account so I plugged the information into SamFirm. I followed the FLASHING UNLOCKED FIRMWARE steps.

You should flash the ROM from the country that has the CSC you want to have, and the same v6 bootloader. You can't downgrade bootloaders.

Stitching to Visible carrier

Forgive me if this question has been answered elsewhere, but I'm not finding it after no small amount of searching. This topic does seem relevant, so Ill try here.

I'm moving to Visible as my carrier, which is a US LTE-only service. They offer the S8/S8+. I have a U1 model S8+ which is not connecting to their network.

The tech support reps tell me that the *unlocked* version cannot be used on their network, only the carrier-issued ones. I'm guessing this is because certain features including TDD LTE are turned off in the firmware to make the phone appealing to certain prepaid providers and MVNO's.

I've switched to the September 2019 version of the Verizon firmware, and my CSC shows as VZW, but I don't see any Verizon branding or apps, and the phone still won't connect. I'm currently at Pie/BL 7.

Will a carrier switch enable these features on my S8+? Any advice on what to do? I'm by no means an expert, but I do believe in reading and following directions.
[Samsung Galaxy S8 Guides, News, & Discussion] alirz:
I believe branding is put in effect based on the SIM card in the phone. If your CSC is ok, they your phone should connect to the network.

Try putting a Verizon card in your phone, if that's what you mvno is using as the carrier.
[Samsung Galaxy S8 Guides, News, & Discussion] k3mot:
Can I do this if i have XEU Carrier ID and i want to have XEO Carrier ID? Becasue:

Same issue here. I can't locate the bootloader 7 versions of the firmware. Where did you download from?
[Samsung Galaxy S8 Guides, News, & Discussion] nrkva:
Update: Success switching to Visible

My phone was originally purchased as a Verizon SM-G950U. Back in December 2017 I flashed the firmware using this guide to SM-G950U1 so that I could use the phone with Sprint BYOD 1 Year Free. With the Sprint BYOD program ending, I wanted to switch to Visible, but Visible doesn't work with SM-G950U1 so I needed to switch back to SM-G950U.

Despite finding the latest version of all of the files mentioned in the guide (bootloader 7 combination file, latest Verizon firmware, and latest Canadian firmware for HOME_CSC file) I could not get the step of updating the IME to XAC to work. No options were listed and XAA showed as the current CSC. The carrier on my phone had always shown VZW however.

After messing with it for quite some time, a user on another thread suggested I use Odin Modded 3.13. Using that version of Odin, the initial step of loading the combination file left my phone showing VZW. From there, I skipped the step of updating the IME, and I went right to flashing the carrier firmware (latest Verizon, downloaded from samfirm) and it worked to reset the phone to Verizon SM-G950U and compatible with Visible.

Here are the links needed:

Bootloader 7 version of the Samsung Firmware:

https://xdaforums.com/galaxy-s8/help/samsung-galaxy-s8-sm-g950u1-binary-7-t4025053#post81363615

Odin Modded v3.13:

http://https://xdaforums.com/android/software/patched-odin-3-13-1-t3762572

Latest Firmware:

Use fw.updato.com to get the latest version listed for your device and carrier/region. No bootloader 7 are currently listed, but just get the PDA, CSC, Phone, and Product Code values from there and put them into SamFirm. SamFirm will then pull up the bootloader 7 version that you need.

Hi. :)

My S8 its from T-Mobile and i cant unlock carrier via IMEI code, i try "Device Unlock" from T-Mobile and give me an error.

So if i flash "Unlocked Firmware (Bootloader v2): Use SamFirm." its good to go and put a code for unlock my device?

Information about my device:

Sorry for my english. :D
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
No must be done through the tmobile app. Or a paid service that specifically does t mobile

They use server side unlocks. Not code unlocks. Any code that you can get aftermarket would be wrong and a waste of money

Thats sad. Even if i flash an unlocked firmware? :(
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Again no. Tmobile does not employ number based unlock codes. It's a server side based system that changes a value in a protected partition. So no it cannot be brute forced either

The g950u1 firmware. But be aware of your current build. In your software info and build

G950FOXM7DTA6. Look something like this. 5th digit from far end is your current revision or bit number. In this case its a 7. So you have to match that or be greater than yours. Or you will get an error
