However, you should prepare yourself for any unknown bugs that you might face. After all, it is only the first set of builds. We might see more improvements, fixes, and feature support later in the course of future releases.

Below are all the features that are working on this ROM:

  • WIFI
  • Bluetooth
  • Camera
  • Gravity & light Sensors
  • Audio
  • USB OTG support
  • Video playback

The developer does credit XDA contributor – USBhost for providing the stock kernel that allowed the ROM to finally boot. So our appreciations go to him too. It requires you to flash his Fire-Ice kernel or the ROM wouldn’t boot at all. You shall also need to have the latest vendor (N9F27H) image and bootloader installed. Now to get Android Oreo on Nexus 9, follow the instructions below.

The ROM will encrypt your device storage, so make sure that you flash the SuperSU or Magisk root package prior to the first boot.
