[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
SO i just wanna start by saying i did not make these files. I simply arranged them together to help out those on cricket wireless like i am and needed Volte working. So here we go.

I also know there are other tutorials with similar things but this is a simple more straight forward process who dont wanna go through all that and wanna just flash in odin.

Required for this

Galaxy S8

ALL FILES NEEDED WILL BE INSIDE 1 FOLDER JUST EXTRACT AND YOUR GOOD TO GO( THE FILE IS 3.87GB)

Unlocked firmware CSB2(in one of the links below)

Odin patched 3.13-Thanks to REALBBB and BLUEFOX721(in one of the links below)

At&T User Data file(in THE FILE)

DOWNLOAD

https://drive.google.com/file/d/15ZQN1Epy8d81N_GNUP2M3gXQPL02kIGL/view?usp=sharing <<<PATCHED ODIN

:::WARNING:::, THIS WILL WIPE ALL DATA ON THE PHONE, PLEASE BACKUP ANY DATA BEFORE THIS PROCESS. I HAVE NOT PROVIDED ANY ADB FILES OR ANY OTHER THING AS I AM SIMPLY DOING A FLASH. IF YOU NEED THOSE FILES PLEASE LOOK ELSEWHERE.

IF YOU DONT WANNA WIPE USE THE HOME CSC AND IT WILL KEEP ALL YOUR INFO ON THE PHONE BUT DOING A DIRTY UPDATE CAN CAUSE ISSUES SOMETIMES.

1. UNZIP THE FILE and you will see 3 folders in it, the UserData file/Patched Odin/Full Oreo Firmware.

2. launch The patched Odin

3. Put you galaxy s8 into download mode by turning the phone off. Then Hold the bixby button and the Volume down button and push the power button.

It will show the download mode and you will then push the Volume Up and you will enter download mode. Plug in your phone thats in download mode now to your computer.

4. Go to ODIN and then select BL, AP, CSC>>>(select the non home CSC), CP and direct each one of those to the corresponding files. SO BL GETS BL FILE, CP GETS THE CP AND SO ON. Make sure to select the NON HOME CSC file. Shut down odin and restart it again as you will need it later. Unplug the phone.

DO NOT SELECT THE USERDATA FILE YET, THAT WILL BE LATER.

5. Once you are ready make sure your phone shows on the ID:COMM up top. If it does go ahead and click START. Depending on your computer this can take anywhere from 4-20 minutes. SIT BACK AND RELAX TILL ITS DONE.

6. Once the phone is done it will restart. (it will say updating system and likely get not that high % and then say erasing-this is normal). Let it load back up to the WELCOME screen. Once it gets to that screen turn the phone completely off again and put it back into download mode(shows how to above in step 3).

7. Launch ODIN again or go back to odin if you already restarted it from the earlier step. Plug the phone back into the computer again once its in download mode.

8. Make sure the phone shows up in odin by looking at the ID:COM, if it does then go down the USERDATA spot and select it and direct it to the userdata file(USERDATA_AIO_G950USQS5CSB1_CL15104926_QB21778972_REV01_user_low_ship_MULTI_CERT.tar.md5) in the USERDATA folder you extracted. Once your sure the phone is showing in the ID:COM and you selected the userdata file go ahead and click start. This process should only take around 3-6 minutes or so.

9. Once the process is complete it will restart at which this time you can unplug the phone. It will take a bit to load up because it fully erased the phone again. IT will likely say updating system and then get to a certain percentage and stop and say erasing(this is normal).

10. You now have an unlocked firmware cricket phone with the Cricket Splash screen and working Volte. setup the phone and enjoy OREO.
