Unable to upgrade firmware on HDFX-2US

[GameGod]

Hi,

I've had the Flex Duo for a while, and have performed a couple of firmware upgrades using the command line tool (hdhomerun_config) on a Windows OS before. However, when I tried to upgrade the firmware to the latest available (hdhomerun3_atsc_firmware_20230505), from 20210422 I get an error message:

Code: Select all

error sending upgrade file to hdhomerun device

I then built a local version of that with debug logging enabled, and I see:

Code: Select all

20250412-11:11:15 hdhomerun_control_upgrade: ERROR: upgrade failed (invalid image)

The md5 of hdhomerun3_atsc_firmware_20230505.bin that I have is 9f07b91721253cec1af680e0ca73c02e

The device seems to be working fine otherwise, and I can get to the webpage on the device IP.

Can someone help me?

Thanks.

"hdhomerun3_atsc_firmware" is for the legacy DUAL gen-3 (HDHR3-US)

For the Flex Duo (HDFX-2US) you need to use "hdhomerun_dvr_atsc_firmware":
https://info.hdhomerun.com/info/downloads#firmware
https://download.silicondust.com/hdhome ... rmware.bin (20231214)
https://download.silicondust.com/hdhome ... e_beta.bin (20250130beta1)

I could be mistaken, but I thought the Flex Duo allowed firmware updates directly from it's webpage.
