Update Galaxy S8/S8+ To Android Oreo with Odin

A couple of weeks ago, Samsung started updating the Galaxy S8 and S8 Plus to Android Oreo. The firmware started rolling out in select regions. At first, the firmware rolled out through OTA updates and then the firmware also made it to the web.Update Galaxy S8/S8+ To Android Oreo with Odin

Galaxy S8 and Galaxy S8 Plus owners were eager enough to grab the firmware files and flash them using Odin. The moment users pressed the start button in Odin, the updated started and crashed in the end. As a result, the phone wasn’t getting updated to Android Oreo.

The initial version of Android Oreo for the Galaxy S8 was also reported to have the random reboot issue. Users reported that their phone was getting rebooted on its own after a specific amount of time.

After coming across all these issues, Samsung pulled back the update. It took the Android Oreo files off from its servers and halted the update for a few days. The update finally started rolling out again about 3 days ago.

It turns out that the flashing issue was related to the compression method used by Samsung for the firmware files. Usually, Samsung uses the .tar.md5 or the .tar conversion for the firmware files. But with the Galaxy S8 and S8 Plus, Samsung used the .lz4 conversion method. The existing versions of Odin did not support the .lz4. There was a workaround that enabled the users to convert the files back to the compatible format. However, Samsung rolled out a new version of Odin that now supports new firmware files.

Now that all the issues have fizzled out, you can flash the Android Oreo on your phone without having any of the previous issues. Android Oreo flashing will go flawlessly with the new version of Android. We did not post a guide to update the S8/S8+ Plus to Android Oreo because there were issues with the previous Odin and also with the previous firmware files. We decided to do a guide when all the issues get fixed. Now that everything is good again, we will take you through the tutorial to install Android Oreo on your Galaxy S8 or S8 Plus.

Have a look at the following steps to update Galaxy S8/S8+ to Android Oreo with Odin. The guide makes the use of Odin 3.13.3 for this purpose. Follow the steps carefully to have the latest Android Oreo running on your S8 or S8+.
