Denon is constantly making upgrades to its software and systems which means your Denon receivers will require a firmware update sometimes. A firmware update will upgrade your Denon AV receiver software without needing an upgrade to the hardware. You will have access to new features and an enhanced user experience. In this article, we will explore how to update your Denon receiver firmware.

To update your Denon receiver firmware, you need to first check if the latest firmware is installed. If it’s installed, so nothing. Otherwise, connect the receiver to the internet and use the setup menu to update the firmware. 

Disclaimer: It is critical that you are careful when updating your firmware since if it is not done properly, you may completely remove the current firmware and the device will stop operating. In addition, ensure that only 1 single firmware file is loaded on the thumb drive that you will use to perform the firmware update.

1. Check If The Latest Firmware Is Installed: How I Know If My Denon Has The Latest Firmware

There are two different methods to check if your receiver has the latest firmware installed:

1. Check The Setup Menu

Before you go ahead and try to update your Denon firmware, you should first check to see if the latest firmware is installed.

For others, it’s not that easy. For example, if you can’t connect the receiver to the internet, you will need to update the firmware manually.

Below, we explain how to conduct a Denon firmware update via USB:

1. Preparing the Update File

When a new firmware is available, you will be able to find it in the DOWNLOADS section of the product page. Just search for your product name + firmware download, for example, search for “Denon AVR 1912 firmware download”.

Once you find the firmware file on the page, download the files and extract them if its zipped. Place these files on a thumb drive that is in FAT32 format.

2. Perform the Firmware Update

  1. Make sure that the receiver is in STANDY mode. If not, turning OFF the unit is OK.
  2. Now insert the thumb drive that contains the firmware file.
  3. Turn the device ON.
  4. You should receive a message on the screen regarding to the firmware update. The updated version will be shown on this screen. Make sure that this firmware version is the one that you want to load into the device.
  5. Select “OK.” to install.
  6. Wait approximately 1 minute for the firmware update process to take effect. You may notice that the screen will blackout. Don’t be alarmed. This is a normal occurrence when updating the firmware.
  7. When the firmware update is complete, your receiver will reboot on its own.
  8. Once the firmware is updated, it is recommended that you check the version and make sure that it’s properly loaded. To confirm the firmware version, use the steps highlighted above.

If you are having this issue, you can revert the AVR’s firmware back to the initial firmware version. This will allow your AVR to reconnect to the network and then receive the current firmware version once again.

However, you will need to redo the setup for your AVR after the new firmware has been installed. To save your settings, you can use the Save/Load option along with a USB drive.

Firmware Regression (Factory Restore) Procedure:

  2. Press and hold the “Button A” and “Button B” buttons on the front panel. Do this while holding in the power on the unit.

Denon Receiver Update Retry Loop

Sometimes, certain issues will cause your Denon receiver to fail to update and simply go into an update retry loop. 

This is likely to happen if the firmware update is interrupted by a power loss or if the USB was unplugged while the update was running for example. If this happens to you, it will be very difficult for you to attempt to fix it. We recommend that you send the device to Denon to have the BIOS reflashed.

However, if you want to attempt a simple fix, you can try the method below:

  1. Reset the receiver as indicated in the manual
  2. Connected the receiver to your network using an ethernet cable. It will not be able to connect via WiFi due to the reset.
  3. Restarted the receiver
