Download Snapdragon S8/S8+ Oreo update G950USQU2CRB9 for Verizon, AT&T, T-Mobile, Sprint

The Galaxy S8 and S8+ are now receiving the latest Android 8.0 Oreo OTA update from Samsung Mobiles. This started with the Samsung Beta Software Program which gained huge popularity for its Samsung Experience 9.0 firmware. The Beta came with Android 8.0 Oreo along with several new features and a new skin. However, the Oreo Beta was meant for only a select number of users. Now that Samsung’s Beta has ended, the Exynos variants have already received the stable Oreo update OTA. It is now time to update the Snapdragon Galaxy S8 and S8+ devices to the stable Android 8.0.

Following the leaked AT&T S8 and S8+ Oreo, Verizon has finally started rolling out the stable version of Android 8.0 OTA. It comes with new firmware build numbers G950USQU2CRB9 and G955USQU2CRB9 for Galaxy S8 (SM-G950U/U1) and S8+ (SM-G955U/U1) respectively.

Now, all the Snapdragon variants from the USA share the same model number. This means all the USA carrier variants can be updated to Oreo using the same Verizon OTA update. This includes Snapdragon S8 or S8+ AT&T, Verizon, Sprint, T-Mobile, etc. holding the model numbers SM-G950U/U1 and SM-G955U/U1

Here in this tutorial, we will show you how to update your Snapdragon variants of Galaxy S8 (SM-G950U) and S8 Plus (SM-G955U) to latest CRB9 Oreo. We will achieve this by first flashing the previous G950USQS2BRB1 or G955USQS2BRB1 using Odin tool. Later we will be updating it to CRB9 stable Oreo using stock recovery or ADB sideload method.

How to update Snapdragon AT&T/T-Mobile/Sprint/Verizon Galaxy S8/S8+ to Oreo?

In order to update Snapdragon Galaxy S8 and S8+ to stable Oreo CRB9 OTA update, follow the instructions below.

While stock recovery install should work perfectly fine, here is the ADB sideload method:

Step 1: Installing BRB1 base firmware using Odin.

  • Make sure you have one of the Snapdragon variants from AT&T, Sprint, T-Mobile, or Verizon S8/S8+.
  • Enable USB Debugging from Developer Options on your device. To do so, go to Settings > Developer Options > enable USB Debugging from there.
  • Setup ADB and Fastboot on Windows, Mac OS, Linux or Chrome OS with quick 15 second ADB installer.
  • Download all the files from above including the full G950USQS2BRB1 or G950USQS2BRB1 stock firmware Odin files and the Oreo OTA update zip with build CRB9.
  •  Transfer all the files for your specific device from the download section to your PC.
  • In order to update to Oreo CRB9, your device needs to be on the BRB1 base firmware. So backup before you proceed as it will perform a clean flash.
  • Extract the BRB1 zip file to get the firmware with .tar or .tar.md5 extension.
  • Reboot your device into Odin Mode [Download Mode]. To do so, turn off your device completely and then press and hold Power button + Volume Down + Bixby keys.
  • Download the Odin tool for PC, extract it, and run Odin software as administrator.
  • Connect your S8 device to your PC using a USB cable.
  • After a successful connection, the ID: COM in the Odin should turn Blue and an Added!! message should be displayed in the Log tab. 
  • Now click on AP button and add the firmware file by navigating to the file path. If there are multiple files, then add them to their proper section.
  • Take care that only Auto Reboot and F.Reset Time are selected on the Options tab. Do not check Re-Partition.
  • Once done, verify everything and proceed with installation by selecting Start button.

Note:  Sometimes firmware could come in 4 different files like BL, CSC, AP, CP. If it’s a 4 file firmware, then add each file to its proper location. Take a look at the image below:

Odin Note 5 Android 6.0.1 MArshmallow

  • When you get a PASS! message in the Log tab on your Odin software, that means firmware has successfully been installed and the device will restart itself. If not, then reboot manually.

Step 2: Installing CRB9 OTA update zip via ADB sideload method

Note: If you think ADB sideload method is not for you, then you can also settle for an easier method of applying updates using stock recovery from here.

Step 1: Make ADB and Fastboot is setup on both Galaxy S8 and PC. Trust the connection at the first USB connection on your Android.

Step 2: Connect Android phone to PC. Now open a command prompt or terminal window on your PC where the OTA update zip is present. To do so, type cmd in the address bar and hit Enter key.

Step 3: Reboot your Galaxy S8 device into Recovery mode. To do so, issue the following command through cmd or terminal.

adb reboot recovery

Step 4: Now go to device recovery and select “Apply updates from ADB”.

Step 5: Navigate to the location where you have placed the OTA file on your PC. It’s time to flash the OTA by issuing the following command. (Note that you type the exact name with its proper extension.)

adb sideload update.zip

Note: Put the exact file name in the <filename> section without “<>” and proper extension.

Step 6: Approve the update and wait till the upgrade completes.

Reboot device to the system. Alternatively, while, on Mac OS, you can issue “./adb sideload <filename>.zip” command or on Linux type “sudo adb sideload <filename>.zip” to flash the OTA. Check out the complete tutorial from here.
