r/Keychron on Reddit: Keychron K2 HE firmware questions
April 5, 2025 -

I'm considering getting a K2 HE and I have some questions regarding the software.

  1. Can I create combos using the Launcher? This is important to me as I use a number of them -- to many to replace using layers.

  2. Am I really limited to only two layers per OS? I can understand that the default configuration only needs two layers but once I want to add my own that is simply not enough.

  3. Can I flash the board with my own version of QMK? This would basically fix the other problems as I can just update everything as I like.

  4. If the K2 HE can't support these requirements, is there another Keychron 60-75% board that can?

r/keyboards on Reddit: Sharing some thoughts on the Keychron K2 HE, curious what others think
June 26, 2025 -

I’ve been using the Keychron K2 HE for a few months now and wanted to share some thoughts on it, especially since it’s one of the more unique boards out there with magnetic Hall Effect switches, adjustable actuation, and pressure sensitivity (even if nothing really takes advantage of that yet).

As someone who cares a lot about design and function, this board really caught my eye. I ended up making a short video review breaking down the build quality, typing feel, the Keychron Launcher software, and whether the magnetic switches actually make a difference in daily use.

If you’re curious about what it’s like to actually live with this keyboard, here’s the video:

Happy to answer any questions about it if you’re considering it or already own one! I would love to get your feedback on the video too :)ts on the Keychron K2 HE, curious what others think

r/Keychron on Reddit: K2 He firmware update
September 10, 2025 -

I'm attempting to update keyboard firmware as the launcher says but device with "boot rom open" won't show up. I'm pressing ESC while connecting the cable and keyboard goes unresponsive (as it should)?

Just download and install it using their instructions. At the bottom, for QMK.

Re "I'm pressing ESC while connecting the cable and keyboard goes unresponsive (as it should)?": Yes, it should. You can positively verify flash mode (AKA firmware update mode AKA bootloader mode AKA DFU mode). It also works on Windows (but see the prerequisites below (at least #1 and #2)). Prerequisites on Windows It is required to install some drivers to flash/update the keyboard firmware. For example, use QMK Toolbox ( this Keychron page has some details on the driver installation (near "Run as administrator")). Prime suspect #1: The notorious Thrustmaster AKA Guillemot driver is not interfering (if it happens to be installed). If it is installed, it may or may not be possible to disable without uninstalling it. Prime suspect #2: SignalRGB is not active. It is allegedly possible to disable it for the current Windows session, without the need to uninstall it. Though it may not affect flashing from the command line (see below), only the configuration tools. If all else fails, do it from the command line (even if not) In a pinch, it is also possible from Linux booted off a live USB stick , say, LMDE (though dfu-util would have to be installed for every session, for example, sudo apt install dfu-util from the command line). BIOS configuration changes may or may not be required for that to work (or at least entering it to select the boot device). Flash from the command-line (with the keyboard in flash mode ): dfu-util -l # Verify bootloader mode dfu-util -a 0 --dfuse-address 0x08000000:leave -D my_awesome_Keychron_K2_HE_iso_encoder_keyboard_firmware.bin It also works on Windows (if the drivers are installed—see #1 above. And if there isn't interference by other software). References K2 HE JSON files for Via (near "K2 HE ISO RGB keymap"). They are also on GitHub . Note: The JSON section should not be confused with the firmware section. K2 HE (main) firmware (near "K2 HE ISO RGB version firmware"). Note: The firmware section should not be confused with the JSON section.
