I have both the Tone1 and Tone2 Pro. I updated the firmware on my Tone2 Pro with no problems, but while updating firmware on my Tone1, I accidentally used the Tone2 Pro firmware file instead.
After I realized my mistake, I tried to use the DFU tool to download the proper Tone1 (V2) firmware, but DFU no longer recognizes the DAC. Is this condition permanent?
Before resigning to tossing the Tone1 in the trash, I connected it to my MacBook Pro. Much to my surprise, it showed up as “Khadas Tone Control” and I’m able to play music through it just fine (listening to a DSD64 album using it as I type this).
I guess this is not the end of the world, but I’m sad that I’ve lost the ability to download firmware to my Tone1 due to this simple mistake. Please let me know if there’s anything I can do.
