Information Concerning Firmware Update for Onkyo Network Receivers
Onkyo has discovered there is a possibility of failure when updating receivers to this new firmware package via ethernet in certain network environments. For this reason, we are now only releasing a firmware file for installation via USB port / flash memory device.
Users should first check to see if their network receiver is running the firmware (1130-9106-0300 or 1130-9106-0301 released August 10, 2012) before installing this update via USB. If your network receiver is not running firmware version 1130-9106-0300 or 1130-9106-0301, please update your receiver to this version via the network facility before proceeding further.
If your receiver is running more newer firmware, there is no need to update via network facility. You can judge whether older or newer by the first three digits.
To check your firmware version, press the â€œHomeâ€� button on your remote control. Highlight â€œF/W Updateâ€� or select the â€œFirmware Updateâ€� icon and press enter. Your current firmware version will be displayed on the front panel of your A/V receiver as well as your TV screen.
Should you encounter any difficulties when performing this update, please contact us.
We appreciate your understanding and apologize for any inconvenience this issue may cause.
