Safe way to update Keychron mechanical keyboard firmware? (lemmy.world)

As noted in the title, I am trying to figure out the safest way to update the firmware on my recently purchased Keychron K1 QMK V6 keyboard. I was finally able to get the web based Keychron Launcher app to talk to my KB after using chmod to give the correct HIDRAW device read-write access but it looks like the new firmware needs another utility to be installed and only the Windoze directions are provided.

From my own online research it looks like there is a terminal-based method but it wasn't really explained. I am not super concerned about updating the firmware since the preloaded version works well enough for my needs but I am still wondering if anyone knew of a tutorial on how to do this without bricking my shiny new keyboard.

I am using Fedora 43 Workstation if that makes any difference. Thanks in advance for any tips or advice!

Follow the instructions here to install qmk and the stuff it needs. Then go to Keychron's website (scroll to the 'Download Firmware and JSON Files' section) and find your keyboard. You should then have a .bin file. Make sure it's the right firmware for your model, Keychron have too many models with similar names and installing the wrong firmware will make the keyboard inoperable (not bricked, as it can still be recovered by installing the right firmware).

You can install this to your keyboard by putting it in DFU mode (remove the space bar and press the small exposed button while plugging the keyboard in) and run the command:

qmk -b <path to firmware file>

This. The QMK environment flashing tools are generic and bundled for convenience, so they will work fine even with firmware files that aren't QMK at all, so long as they're for your keyboard or chipset. I use them to flash Soarer's style firmwares on Tuxedo OS.

Thank you for the detailed response. It will be good to have this information available if the need ever arises to necessitate updating the firmware for a more critical issue or feature. That said, I think I will accept the cautions and hold off on taking this action for now.
