Android 8.0 Oreo is now official and its system images have been made available by Google for devices such as Google Pixel, Pixel XL, Nexus 5X, Nexus 6P, Nexus Player and Google Pixel C. The flashing instructions are available here. Users are required to perform the backup of their devices before installing Android 8.0 Oreo through system images. The search engine giant has also released Android 8.0 Oreo OTA updates for the devices that have enrolled in Android Beta Program.
Installing Android 8.0 Oreo manually through system images may not be convenient for all even though Google is offering a hassle-free installation process now. The easiest way to get the Android 8.0 Oreo before it is officially released by the carrier or the smartphone vendor is by joining the Android Beta program.
Users of Google Pixel XL have claimed that updating to Android O from Developer Preview 4 has been unsuccessful. However, Google seems to have resolved the issue. The OTA update is available without any problem for Nexus 6P and Nexus 5X smartphones enrolled in Android Beta Program.
Fixed now. We had a signing issue for beta users.
