The Denon AVR X250BT is now, post-firmware, the rock-solid entry-level receiver it was always meant to be. Have you applied the fix? Share your experience in the comments below. For additional support, visit Denon’s official firmware page or the AVSForum Denon Owner’s Thread.

The new firmware also includes minor security patches for the network stack and improved compatibility with the latest HDMI 2.0b source devices (e.g., PlayStation 5, Xbox Series X). While you can skip it, Denon will likely require this version as a prerequisite for future feature updates (such as new Alexa voice control integration rumored for later in 2026). Conclusion: A Rare Win in AV Firmware History AV receiver firmware updates are notorious for causing more problems than they solve. However, the Denon AVR X250BT firmware update labeled as “fixed” by the community genuinely lives up to the name. The HDMI ARC stability, Bluetooth reliability, and remote responsiveness have all seen measurable improvements.
