Denon staggers rollouts by serial number to manage server load. Try again in 24–48 hours. Alternatively, your region’s server may be behind. Use the USB method to bypass this wait.
The primary purpose of a firmware update for the AVR-X520BT is multifaceted. First and foremost, updates address bugs and glitches discovered after the product’s release. Early adopters of the X520BT occasionally reported issues such as audio dropouts over ARC (Audio Return Channel), failure to recognize HDMI 2.0 sources, or erratic behavior when switching between Dolby Digital and DTS codecs. A firmware patch directly targets these operational flaws, stabilizing the core decoding and amplification processes. Secondly, updates often introduce compatibility. As streaming services and gaming consoles evolve, so do their copy-protection standards—namely HDCP 2.2. A new firmware version ensures the receiver remains compliant, preventing a black screen when a 4K Blu-ray player is connected. Lastly, updates can unlock subtle performance improvements, such as faster input switching or more reliable Bluetooth pairing for the X520BT’s wireless streaming capabilities.
Firmware updates for the AVR-X520BT typically provide:
Typically depending on your internet speed. USB updates are slightly faster (10–20 minutes).
If the update fails, the unit may display "Update Retry" on the front panel. In such cases, you should re-insert the USB drive and restart the process. For persistent issues or if the firmware becomes corrupted, Denon recommends contacting an authorized service facility . Firmware AVR-X520BT
