Flash button is disabled

[rickyManalo]

Describe the Bug

After following the instructions here, the Flash button seems to still be disabled. QMK already detected the keyboard as well. It already shows

HID console connected: Keychron Keychron C2 Pro (3434:0520:0101)

System Information

• Operating system: Windows 10
• QMK Toolbox version: 0.2.2

The latest Toolbox release currently does not include WB32 bootloader support. You can try the beta or use Keychron's version instead.

Can you point me to those apps?

I tried the beta version, and it doesn't seem to detect the keyboard. Fortunately, 0.2.2 still can detect it

[fauxpark]

You need to put the board into bootloader mode. The HID console connected line is unrelated, it just means the Console feature is enabled in the firmware.

Hmm, how do I do that? The guide from Keychron only said to hit fn + J + Z to go to DFU mode

[fauxpark]

Try holding down the top left key while plugging it in.

[rickyManalo]

You mean the esc key? The guide said that I need to hold the reset button. Can I not do that and just hold the esc key?

[fauxpark]

Yes, this is the Bootmagic feature, which checks a specific matrix location (usually 0,0 - hence why I said the top left key and not Escape) on startup to determine whether to jump to the bootloader.

[rickyManalo]

It seem to do something, but QMK didn't show that the board went to bootloader mode. The keyboard just didn't turn on the lights

The Toolbox may not work for this bootloader anyway - it uses an older version of dfu-util which has an issue with the L4 series, IIRC. I'm trying to get a new Toolbox released soon, but you may have to just use the CLI method of flashing for now... as long as your dfu-util version is fairly recent.

I see. Well, I'm really not in a hurry. I just wanted to change my lighting and found out that my board is having some issue with VIA. Do let me know once you've that new build so I can test it out. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free.www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
