remapping keychron v3 via/qmk on linux? how to upgrade/reset the firmware?

The hardware reset button just let the keyboard boot into flash mode. If nothing is done, you can simply unplug and replug so the keyboard would boot into normal mode again

Source: I uses qmk from the terminal

So you mean it would have no effect, yes? On restart it will have the same settings and firmware it did prior to pressing the reset button?

I looked at the QMK docs to see about using it from the terminal. But I am not clear about how to get around the issue of the firmware not being up to date.

I don’t quite trust various bits and pieces I’ve found about how to use it around the web. Like the configurator page for this device says

Reset Key: Hold down the key located at K00, commonly programmed as Esc while plugging in the keyboard.

compared to the keychron docs I linked to in the OP which says

reset the keyboard by pressing fn + J + Z (for 4 seconds)

And also describes an actual reset button located under the space bar.

Why are they different…? It seems like keychron probab knows how to reset their own device. So I wonder if it is a good idea to load anything from this qmk page using methods I don’t understand well because I’d never be able to get myself out of a mess.

Ah I see there is a confusion. The button under the space bar is the flashing mode button, only for flashing new firmware. The factory reset is for when you brick the keyboard.

When I flash firmwares I use the button under the space bar. I remembered screwed up once , but I forgot which key combo I used to reset it.
