qmk_toolbox VS mdloader

Flashing custom firmware - the current version QMK tool off the website won't work. You'll most likely get a "USB device connected (NO DRIVER): WB Device in DFU Mode " and not be able to flash anything. You will need the beta version that supports WB32 flashing utility. I grabbed mine from the GMMK guide QMK tool from GMMK

You first have to download QMK toolbox https://github.com/qmk/qmk_toolbox/releases/download/0.2.2/qmk_toolbox.exe. Once downloaded, download this bin file https://github.com/GHv4/Sense75-CAPSLOCK-UNDERGLOW/blob/main/sense75-CAPSLOCK%20UNDERGLOW.bin. Open the QMK toolbox exe file, then hit the open button. Locate the .bin file. Hold Right FN+BACKSPACE until it pops up in QMK Toolbox. Hit flash and wait for it to finish flashing. Via and Vial compatible. YOU'RE WELCOME FRIENDS!!

Flash it with qmk toolbox: https://github.com/qmk/qmk_toolbox/releases

I got things working by using the https://github.com/qmk/qmk_toolbox project, and the firmware file you linked. As you said, my pad now works with Vial, and has 12 layers. Though the layer selector still only traverses between layers 0 through 3.

- QMK MSYS: you'll need it for many things, for compiling your firmware file and for flashing, especially if flashing with QMK Toolbox isn't permitted in firmware settings (in this case QMK Toolbox just won't recognize your keyboard);

I am currently using the QMK online configurator tool to do the compilation and download the resulting .bin file, and then the QMK Toolbox to flash it onto the keyboard.

Check out this site: http://kpchn.com/s/PoHJ. I found it from the AliExpress page and it leads to all the VIA/VIAL configs for the KPRepublic boards. Go into CSTC75 and you'll see a .hex file, that's the firmware. You should be able to use the QMK toolbox: https://github.com/qmk/qmk_toolbox to flash the firmware.

When I first plugged them in, my Mac (running 13.1 Ventura) recognized them as a USB storage device. I was trying to use the QMK toolbox to flash the firmware onto them, not realizing that I needed to drag and drop a .uf2 file instead of trying to flash a .hex file.

They have a newer release that has a integrated applet file, iirc. Are you using this version? https://github.com/Massdrop/mdloader/releases/tag/1.0.6

looks good to me. windows even marked them as binary file. They are not made for you to open them, but upload in special program (mdloader i guess). Just read unstructions from here https://github.com/Massdrop/mdloader

There are no devices available

Ok, I found something that I'll try: https://github.com/Massdrop/mdloader/releases

- Atmel SAM-BA (Massdrop) via Massdrop Loader (https://github.com/massdrop/mdloader)

This one worked for me: https://github.com/Massdrop/mdloader/releases (just replace the mdloader and applet files)
