Hello, there. This is my second guide, so please forgive me if it looks a bit weird. But without further ado I present you with my Official [Snapdragon] Guide for Flashing Standard Firmware, Carrier Switching, and Flashing Unlocked Firmware for the S8+.[/SIZE]
Here are some useful reminders:
All download links are at the bottom of this post.
Make sure you follow the "Prerequisites For Anything You decide To Do In This Guide" section.
Don't copy quotation marks, unless I tell you to in this guide.
You will need a Windows computer in order to utilize the software provided. Mac users can use Boot Camp to dual boot their machines. Using WINE is not recommended.
This is an S8+ guide, not an S8 guide. Go to https://forum.xda-developers.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817 to check out my S8 guide.
WARNING: Anything you do in this guide will erase your phone completely. It's recommended that you back up before you do anything and that you remove your Google account from your phone (so you don't have to go through FRP).
Note: Flashing to stock from Unlocked firmware requires you to follow the "Carrier Switching" section (which eventually requires you to follow the "Flashing Standard Firmware" section) and do as it says, unless the CSC code of your carrier is currently active. You can check this by going into Recovery Mode by holding the Power button, Bixby button, and Volume Up button until you see a dark blue screen with text saying that the firmware is being updated (it's not actually). Once it transitions to a black screen, your active CSC will be on the bottom log (three characters). If your CSC code is already your carrier's, then just follow the "Flashing Standard Firmware section. But for anything you decide to do, you must follow the "Prerequisites for anything you decide to do in this guide" section.
Disclaimer:
I am NOT responsible for any damage done to your device if you decide to use this guide.
Prerequisites for anything you decide to do in this guide (Required):
Standard Odin
Samsung Drivers
Steps:
1) Uninstall Samsung Switch and/or Samsung Kies, if present on your computer. This helps removes any conflicts with Odin.
2) Extract the Samsung Driver zip and the Odin zip to somewhere safe on your computer.
3) Double click on the extracted "SAMSUNG_USB_Driver_for_Mobile_Phones" executable (SAMSUNG_USB_Driver_for_Mobile_Phones.exe).
3) Navigate to your extracted Odin folder and double click on the Odin configuration file (Odin3.ini).
4) You should have entered Notepad (or your preferred note editor). Find the "[ButtonOption]" section.
5) There should be a setting there called "UMS/PATCH". Change the value of "0" to "1" so it becomes "UMS/PATCH=1".
6) Press the "Ctrl" key and "S" key on your keyboard to save the file.
7) Go ahead and close out of Notepad.
All About Bootloaders (Required Reading):
As Wikipedia puts it, “A boot loader is a computer program that loads an operating system or some other system software for the computer after completion of the power-on self-tests.” In other words, a bootloader is what loads you operating system. In most Samsung phones (including the S8 and S8+), there’s an e-fuse that prevents downgrading of the bootloader. This means any firmware or firmware update containing a lower Bootloader version than the one you have, will FAIL to be applied. There is really no way to circumvent this.
(From what I can tell) S8+ firmware released since December are Bootloader v2, while anything before that month is Bootloader v1. In the next section, I’ll be explaining how to properly identify your current Bootloader version.
How to identify Bootloader version (Important):
Steps:
1) Open “Settings” on your phone.
2) Scroll down to “About Phone”.
3a) If you are on a standard, carrier firmware, under “Baseband version” you should see something similar to this: “G955UXXXXXXXX”.
3b) If you are on an unlocked firmware, under “Baseband version” you should see something similar to this: “G955U1XXXXXXXX”.
4) No matter which firmware you're on, the fourth “X” would be either a “1” or a “2”, which means you will have either Bootloader version 1 or Bootloader version 2, respectively.
Note: As stated in the last section attempting to flash firmware that contains Bootloader v1 onto a phone that already has Bootloader v2, will fail. You can update a phone on Bootloader v1 to a firmware that has Bootloader v2, however.
How To Download Firmware with Updato:
Note: This is an add-on section for any part of the guide that requires you to download specific firmware.
Updato can download old or new firmware for phones, therefore you can download Bootloader v1 or Bootloader v2 firmware. However, Updato tends to be much slower than SamFirm, therefore its recommended that you use SamFirm if you’re willing to download Bootloader v2 firmware. You should only use Updato if you need to download Bootloader v1 firmware.
Steps:
1) Go to http://fw.updato.com
2) Type in your Model Number (SM-G955U for carrier S8+’s; Firmware for unlocked S8+’s can be found in the “Downloads” section)
3) Find firmware for your specific region.
Here are some common Region codes:
BST Boost
VZW Verizon
ATT ATT
USC US Cellular
ACG C Spire
TMK MetroPCS
VMU Virgin Mobile
TFN Tracfone
XAS Sprint
TMB T-Mobile
XAA Unlocked US
SPR Sprint
CCT Xfinity Mobile
AIO Cricket
4) Download it somewhere safe onto your computer.
How To Download Firmware with SamFirm (Faster):
Note: This is an add-on section for any part of the guide that requires you to download specific firmware.
SamFirm can only download the latest firmware for phones, therefore you’ll be downloading a Bootloader v2 firmware (which means once you flash it, there's no going back to Bootloader v1 if your phone is currently on that version). SamFirm tends to be much faster than Updato for downloading firmware, since the firmware is downloaded directly from Samsung.
Prerequisites:
SamFirm (SamFirm_v0.3.6.zip):https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
Steps:
1) Download “SamFirm_v0.3.6.zip”. Make sure you’ve installed all of its prerequisites listed on the page, such as “.NET Framework 3.5”, “Microsoft Visual C++ 2008 Redistributable Package (x86)”, and “Microsoft Visual C++ 2010 Redistributable Package (x86)”
2) Extract “SamFirm_v0.3.6.zip” somewhere safe onto your computer.
3) Double-click on “SamFirm.exe” to open it.
4) Enter your Model Number and 3-character Region code.
Here are some common Region codes:
BST Boost
VZW Verizon
ATT ATT
USC US Cellular
ACG C Spire
TMK MetroPCS
VMU Virgin Mobile
TFN Tracfone
XAS Sprint
TMB T-Mobile
XAA Unlocked US
SPR Sprint
CCT Xfinity Mobile
AIO Cricket
5) Make sure you’ve ticked the “Manual” checkbox.
6) Input your “PDA”, “CSC”, and “Phone” strings into their respective slots based off the information found from fw.updato.com for your latest specific firmware. Please note that the “CSC” slot is not the same as the same as the “Region” slot; the “CSC” slot should have a long string inputted.
7) Tick the “Binary Nature” checkbox.
8) Click the “Check Update” box.
9) Your firmware should now appear. Make sure the “Check CRC32” and “Decrypt Automatically” checkboxes are ticked.
10) Click on the “Download” box, choose where you want to store the firmware, and relax for a while.
Flashing Standard Firmware:
Prerequisites:
What's listed in the "Prerequisites For Anything You Decide To Do In This Guide" section.
Firmware you want to flash; follow the “How To Download Firmware with SamFirm” or “How To Download Firmware with Updato” section, if you need firmware.
Steps:

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", the "CSC" box will require a firmware file that starts with "CSC" (DO NOT USE THE "HOME_CSC" file for the "CSC" box), the "UMS" box will require a firmware file that starts with "USERDATA". The "AP" and "USERDATA" files will take the longest for Odin to load because of their size.
10) Go to the "Options" tab and make sure that only the "Auto Reboot" and "F. Reset Time" checkboxes are ticked.
11) Go back to the "Log" tab.
12) Click the "Start" button on bottom right.

I guess what I am trying to say is, a brief explanation to both would be a good addition to the thread.
Pros and Cons.
Why would I want to odin an unlocked FW oppose to keeping my Verizon FW besides removing a few bloat?

Truthfully, I don't need a shout out or anything. I just know noobs are ready to flash anything and everything with the word unlocked without knowing what it is or what it does.
Pros and cons would be a good addition but will require more research time and feedback from people who are using the unlocked FW.

I'll still shout you out (at the top of my guide)... I do have an S8, and can tell you that VOLTE and Wi-Fi Calling are not in the settings with the Verizon firmware or with the unlocked firmware by itself (meaning that the SIM card was removed and the CSC was set to "XAA"). Therefore, that has led me to believe that Samsung themselves, have not implemented any carrier exclusive features, such as the ones stated above. I also collected some input from the users at the S8 guide, and they report the same things.
Oh, I want to point out that there IS a stock AT&T firmware for the S8+.
On the S8, there isn't.

Yes, that's what I mean by standard firmware (sorry, if I confused you). Your CSC code is already set to "ATT", correct? If not, follow the "Carrier Switching" section and then the "Flashing Standard Firmware" section. If your CSC code is alrready set to "ATT", then just proceed with the "Flashing Standard Firmware" section.

I recently picked up an AT&T tab with the intent of making phone calls and using my unlimited data plan on it on the AT&T network. It took me a while to read all the posts on XDA and understand the process and the Odin tool before I felt comfortable flashing it. I thought I'd outline the steps that worked for me and maybe save others some time
I very well could have forgotten a step and I am in no way responsible if you damage your tab. Doing this will void the warranty
All credit for this working goes to clubtech, samfirmware.com, rotohammer and CLShortFuse with special thanks to clubtech.
The original, main thread can be found here: http://forum.xda-developers.com/showthread.php?t=847273 and should be read through in it's entirety if problems occur.
These instructions are designed to use with an AT&T branded samsung galaxy tab on the AT&T network only
1. Root phone using SuperOneClick (courtesy CLShortFuse)
http://forum.xda-developers.com/showthread.php?t=803682
You will need to turn the phone on, unplug from computer, enable usb debugging and run the program
2. perform a rotobackup (courtesy rotohammer)
instructions: http://forum.xda-developers.com/showthread.php?t=850359&page=5
You will need the android sdk installed and be comfortable running a few commands
3. Download files indicated in first post of thread: http://forum.xda-developers.com/showthread.php?t=847273
4. Decompress the file P1000XWJJ4
4. Put the phone into download mode by holding power and volume down for a while
5. Insert your non-prepaid sim card with voice and data plan and run odin (odin is used to flash the device):
a. click pit button and select the file "P1_add_hidden.pit".
b. click pda, phone and csc buttons selecting the file names indicated in the screenshot attached here.
c. Check Re-Partition
d. Click Start
6. The phone should restart and be in Russian
7. Put the phone in download mode again
8. In Odin, uncheck repartition selected and click Reset
9. Click PDA and select the file P1000OXAJK5.tar
10. Click start
11. After success and the phone restarts, put phone in download mode again
12. Click reset in Odin, click modem and select modem.bin from the file modem_bell_i9000.zip and click start
Phone should reset and be wonderful.
Hi
Great post - just want to confirm i was able to do it all without steps 1 and 2 (i.e. no need for rooting).
Thank you for this quick guide.

Hi guys! This is a noob-proof guide on how to flash stock samsung firmware on your i9300. Whether you have bricked it or just want the stock firmware back. Here's how to do it (detailed explaination)
WARNING! : This is only for the GT i9300 (international version) , Check your device before proceeding. Also you might lose all your data. So backup! i am not responsible if you brick your phone(although very unlikely) by not following the guide properly
Also you will lose your custom recovery, Custom ROM and will not longer have root
Ok lets begin!
1. Make sure you have the samsung drivers installed on your pc (http://bit.ly/SDaIIE)
2. Your device should have at least 80% battery left
3. Enable USB Debugging by going to Settings>Developer Options>Tick the Usb debugging tick box!
Files needed :
1. Android 4.1.2 I9300XXEMA1 for Galaxy S3 I9300 - http://bit.ly/10vkxdj
2. Odin 3.07 - http://bit.ly/16aRzF4
Extract The firmware Zip file until you get a file with a .tar extension and some other files. Do not extract furthur
Extract odin zip file till you get Odin3 v3.07.exe
Now here comes the actual flashing part
1. Power off your smartphone. Wait 5-6 seconds for vibration to confirm complete switch off.
2. Now, get into Download Mode by pressing and holding Volume Down, Home and Power button simultaneously until Samsung Galaxy logo appears in phone screen. Wait few seconds and your phone will be in download mode.
3.Open odin as administrator and connect your s3 to your computer with usb cable
4. You will get a message "Added" in the message box in odin and You should also see COM port with a number in Yellow if you successfully added your device.
if you don't get this , try another usb port.. if it still doesn't come , reinstall drivers.
5. Select these files from I9300XXEMA1 folder in Odin at respective buttons:
Click the PDA Button, and select the .tar.md5 file here with *code* appearing in its name
Click the Phone Button, and select file with *modem* in its name (leave if there is no such file)
Click the CSC Button, and select file with *csc* in its name (leave if there is no such file)
Click the PIT Button, and select the .pit file. Use only if you got it while extracting , otherwise ignore it.
6. make sure Auto Reboot and F. Reset Time checkboxes are selected. Also, make sure that Re-Partition checkbox is selected, only if you are using a .pit file
7. Double check everything above and hit start!
8. once flashing is complete the phone will reboot automatically and soon you will see a PASS message with green background in the left-most box at the very top of the Odin. You can then unplug the USB cable to disconnect your device from computer.
congratz , you have just restored your i9300!
If this has helped you make sure to hit the thanks button!
what have you developed?
We already know Odin, and this doesn't UNBRICK anything
Sent from my GT-I9300 using xda premium
This is so worthy of development thread. ...:banghead:
Sent from my GT-I9300 using xda premium
Helpful post to some,,,,,however the unbrick part is misleading as all this does is flash a stock ROM.
Only soft brick... like any other Samsung device.
Reported not development plus we have all this information already posted .
OP is splattering this post all over the forum .

In various places it has come to my attention those lamenting they cannot root their Verizon Note 3 due to Firmware version. This is likely common knowledge among those in the know, but to many NOOBs like me coming here, it is not so obvious!
The first thing you need is the 0F1 firmware https://stockromupdate.com/2016/06/22/stock-rom-sm-n900v-samsung-galaxy-note-3/
Next you need Odin on your PC http://odindownload.com/
1) Unzip Odin putting the folder somewhere easy to find like the desktop
2) Unzip the 0F1 firmware to the Odin Folder
3) Boot your Verizon Note 3 into Odin mode (Volume Down, Home, and power) using the up volume to get past the warning and actually into download mode
4) Connect your phone to PC using USB connection
5) Launch Odin (You will know it is connected when you get both a blue box in the lower box of the upper row of small boxes and the text box on the lower left says "added"
6) Tick the box next to the AP
7) Click AP and select the 0F1 firmware and let it scan in
8) Click start (If you click before the firmware is accepted, Odin will stop responding)
9) Check your software version after reboot and you will have the 0F1 firmware.
As far as your phone is concerned it simply updated itself. Backing up your data is always recommended, but do not be surprised when all your data and apps remain intact.
Please note Kies (Samsung Smart Switch) can be used as well as Odin, but everything will reset back to factory like it has never been used which may be your choice, thus included.
Smart Switch can be found at http://www.samsung.com/us/smart-switch/
My wife and I have ATT S8's which were updated OTA to PIE a couple of months ago and since then, we have been fighting with high battery drain. I've done several full complete wipes and even replaced the 1.5yr old original battery on my phone thinking it was bad, yet still, both phones drain with little to no use. By late afternoon, the battery is down to the teens.
I'm 100% convinced it's PIE, based on other complaints of battery drain since their S8's were updated to PIE.
So I want to downgrade back to a factory ATT OREO firmware. Both phones are currently on PIE version G950USQSDSE5. Can I safely downgrade to an official ATT OREO firmeware, ie. G950USQS5CRL1 or G950USQS3CRE2 using ODIN without the risk of bricking?
If so, what is the correct ODIN process to follow? I've read different instructions.
One of them reads:
1. Download and extract a zip file containing your desired firmware.
2. Open Odin Tool.
3. Boot your device in the "Download Mode": Press Volume Down, Power and Home buttons at same time for 5-8 seconds until download mode is active.
4. Connect your device to PC via the USB cable while in download mode.
5. Next, check the "Auto Reboot" and "F. Reset Time" options in Odin Tool.
6. Hit the AP/PDA button then browse and select a tar.md5 file from the extracted folder.
7. Finally press the start button to begin flashing the firmware update on your device.
Another guide states:
Extract the firmware file you just downloaded. You should get 5 files:
AP (System &Recovery)
BL (Bootloader)
CP (Modem / Radio)
CSC_*** (Country / Region / Operator)
HOME_CSC_*** (Country / Region / Operator)
Add each file to it's respective field in Odin v3.13.3. Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data.
Reboot your phone in Download / Odin mode (make sure your device is off) with the following button combo: POWER + VOLUME DOWN + BIXBY
Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a BLUE box will show up with the COM port number. (Be sure, the SAMSUNG-drivers are installed on your PC!)
Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.
Click the start button, wait for Odin to say 'PASS' in a GREEN box. Once the flash is complete, your phone will reboot, and you can disconnect your phone from the PC.
Any help to get us back to OREO is greatly appreciated!
I was able to successfully downgrade, but even with disabling software and security updates, PIE forced it's way back onto my phone after a week or so. I need to find a way to block updates so I can go back to Oreo and stay on it.
Hey, I have the same phone and I am having an issue finding the correct firmware for it. Can you give me a link to the firmware you downgraded to that worked? I just flashed it with ODIN, but the firmware I used caused it to get stuck in a bootloop on the ATT screen and it wont turn on. Thanks!
I need to do this to my S8 Active. It finally went to Pie a few days ago and I cannot stand it.
Hi you all for those trying to unlock and root the Samsung Galaxy S8 SM-G950U snapdragon locked for USA sprint company. Voila! it is possible even if you got the 6th version firmware (latest update to October 28, 2019)
After some days trying to root and lock unsuccessfully and looking info I gave a shot to movical wesite. Price is very cheap and they guide you into the process. Basically the steps are:

2- Select you phone model and Insert the license provided by movical website in the search bar.
3- Install samsung drivers into the pc and connect the phone via usb to pc
4- Open the device manager (window+x ) and see what type of connection is showing the phone. If it say "modem" it will no work. You must set up to "ADB" for that follow this step (two options):
First developer option must be activated
4.1 Dial *#0808# if this not work (in my case didn't) then
4.2 Dial ##3434# when prompted select CMDA, another screen will show up, then tap on DM+MODEM+ADB.
4.3 Check again device manager after plug the phone again into pc it should now say "ADB"
5- Run Unlock client set up the settings and it will return a message that is not possible unlock cause flash must be done first and the software provide the link to download the files needed for make the flash
6- Flashing:
Open Odin and set up the file recomended by unlock client software on the Odin ( i used v3.13 version) AP section. Let Odin software do the rest. Voila you phone has been flashed.
7- After flashed turn on the phone and plug it again into the pc
6- Set up and Run the Unlock client software again and voila this time the software is able to unlock the phone the message " Unlocked" should be displayed on the screen.
8- Recover to stock room
8.1 Download the files recomended by unlock client for recovery
8.2 Open Odin and set up all the files Ap, BL, CP, CSC (you got two option here if you select CSC home yo got the sprint logo back if you dont want it then select CSC file) and USER Data
