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.
If it’s installed then you don’t need to do anything. Use the following steps to find out if your AVR has the latest firmware installed:
- Turn on your AVR.
- Press the “Setup” button on the remote control to access the setup menu.
- Select “General” from the menu.
- Then, select “Firmware”.
- Select “Check for Update” from the Firmware menu.
- If there is an update, select “Start” or “Update” or “Install Update” to install the new firmware. However, the device should be connected to the internet as explained below in the Heos section.
If your AVR is updated with the latest firmware, then a “No update required. Latest version installed” message will appear on the screen. If AVR needs to be updated, follow the instructions on the menu.
Here is a quick example:
2. Use The HEOS app
Below is the step by step method that you can use to check the firmware from the Heos app:

2. Update Your Denon Receiver Firmware
For some receivers, updating the device is as simple as choosing the update option from the setup menu after you have connected it to Wifi.
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
- Make sure that the receiver is in STANDY mode. If not, turning OFF the unit is OK.
- Now insert the thumb drive that contains the firmware file.
- Turn the device ON.
- 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.
- Select “OK.” to install.
- 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.
- When the firmware update is complete, your receiver will reboot on its own.
- 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.
Does The Denon Receiver Firmware Cause Problems?
Some users report various issues after updating their Denon firmware. These Denon AVR firmware update problems are reported in forums all over the internet. The main issue has been problems with the network connection after a recent update.
How To Fix Denon Network Connection Issue After Firmware Update
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:
- Put the unit in Standby mode. (Zones powered off)
- Press and hold the “Button A” and “Button B” buttons on the front panel. Do this while holding in the power on the unit.
- You will see “Restoring FW…” on the display.
- Release the 2 buttons and give the receiver about 10 minutes to complete.
Other Denon Receiver Problems
Denon receivers are known to have other issues that may not be due to a firmware update. For example, if after a firmware update your Denon receiver turns off and binks a red light, check out this guide.
Denon AVR 1912 or 1913 Firmware Update
To update the AVR 1912 firmware, follow the procedure below:
- Connect the receiver to the internet
- If the firmware notification comes up, select “SETUP” or if not, go directly to the setup menu.
- Select “GENERAL” and then select “FIRMWARE” followed by “UPDATE”.
- Select “CHECK FOR UPDATE”
- Finally, select “Update” and the AVR 1912 or 1913 receiver will automatically update.
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:
- Reset the receiver as indicated in the manual
- Connected the receiver to your network using an ethernet cable. It will not be able to connect via WiFi due to the reset.
- Restarted the receiver
- Update retry
