I followed the guide and installed the new firmware from the link above, but for some reason the firmware won’t update. The DFU tool clearly shows “success”, but when I reopen the DFU tool to check, the version is still the previous 1.14. I’ve tried using a USB 2.0 port and different cables, but it didn’t help at all. Reinstalling drivers or running the program as an administrator also made no difference.
Is there anyone who has experienced the same issue or knows how to fix it? As far as I know, most DACs have a firmware update mode, so I’m not sure whether this issue is related to the device settings or the firmware itself.
