Alt keyboard seems dead after firmware update

more_vert
Received the Alt keyboard this morning. Connected it to my MacBook Pro, and worked well. I then attempted to load a new firmware, and after what seems to be a successful firmware update, the keyboard seems completely dead - there are no lights or any response whatsoever. Please advise...

I had the same issue. I was able to fix it by flashing the keyboard again using sudo: sudo ./mdloader_mac --first --download myconfig.bin --restart

Same issue here, I turn it on and get no response, can hit the "reset" button on the bottom and get a solid orange light, but even after a successful flash it fails to respond. Is this thing just dead? No reset, really?

Are there any updates on this? I'm having the same issue. After flashing a firmware update, the keyboard no longer turns on. 1) The applet-mdflash.bin file is in the same folder. 2) Definitely flashing the fireware bin, not the applet bin. 3) Also tried turning off, removing and repluggin in, and flashing using th eQMK Toolbox. All the same. I can flash the fireware and it says that it's been successful, but afterwards the keyboard does not turn back on. If I press the reset button, an orange light turns on which I know represents a connectivity issue. 4) I definitely have --restart at the end.

@jxliu is correct. Although the keyboard seemed to be dead/unresponsive, I was was able to reflash it with the correct firmware file by running the QMK Toolbox and pressing Fn-B to put the keyboard in DFU mode.

How did you manage to do this? My board is dead, no lights+completely unresponsive. QMK toolbox just says "there are no devices available"

You need to flash the firmware file you downloaded, not applet-flash-samd51j18a.bin

I did the same stupid thing to my drop ctrl. I described it in my post under Tech. does that mean the PCB is totally wasted? is there anything can be done to revert the change please? thanks.
@jxliu Any ideas?

Wow, I guess it's not just me. Saw the exact same thing, updated the firmware, it worked for a little while, now it's completely dead.
