qmk_toolbox VS qmk_firmware

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.

I had trouble with HMR as well at the beginning, but since switching to sunaku's fork/PR I've almost eliminated all the issues I had with it. And worth mentioning is urob's timeless HMR config from which I think the fork/PR takes some of its inspiration.

Affirmative. I updated my fork and my clone last week. I also did a second, fresh clone and merged this PR: https://github.com/manna-harbour/qmk_firmware/pull/56

Im guessing installing something like this is what i need to do? https://github.com/manna-harbour/qmk_firmware/pull/56

See my Miryoki PR for details: https://github.com/manna-harbour/qmk_firmware/pull/56

I have a separate system for that as part of this old unreleased project. They're orthogonal so could be used together, but it'd be nicer if they were integrated. If you just want to remap buttons or map buttons to keys you can do that in the OS.

Well, things like Bilateral Combinations are aware of which hand is using the modifier to only apply it to the other side's presses & minimise accidental triggering on same-hand rolls.
