The existing versions of Odin failed to flash the .lz4 files as they do not support this format.

So, in order to flash Android Oreo on Galaxy S8 manually, you have to use the new version of Odin which is the Odin 3.13.1. It’s already available on our site. Have a look at this guide to manually update Galaxy S8 or S8 Plus to Android Oreo without any errors.
