May have bricked KB16-01

[Bestmixtape]

Hi, I tried to flash my KB16-01. The flash seemed to be successful the first time, with the Rainbow Style RGB backlight on the macropad after the install, but even after a reset, it wouldn't get detected in VIAL.

I tried the firmware update again, and I believe that was an error on my part, and now the macropad seems to be bricked. It gets detected in QMK toolbox, but I get a firmware update issue.

OLED doesn't light up, nor does it get detected in VIAL. It has the APM32 Chipset.

Update

I was able to re-upload the firmware by playing around with reset button on the PCB.

But still can't get it detect in VIAL.

I tried CLI, updates okay from there too, but still nothing in VIAL on both MacOS and Windows 11.

try this one

[thompson-vii]

if it still doesn't work then you might have bricked the bootloader

i would check with the qmk discord then.

Mine has got bricked too during the flashing of this firmware. Got a message "Error during download get_status (LIBUSB_ERROR_TIMEOUT" at 76% of the download.

Has anybody tried to unbrick it with "st-link v2 dongle"?

Edit on July 13, 2023: Found the reason why it was bricked: the firmware I downloaded was 145KB (I right clicked the file on the main page then saved it, it is actually a text file! Why it works like this?) I downloaded again today and it is 60KB. I unbricked it with "st-link v2 dongle" and flashed kb16_rev2_vial_fw again. It is working!

Thanks to @thompson-vii for this great work!

I accidently used this on my KB-16 (1) and it works fine. Just make sure your following instructions properly

@yardern how did you manage to unbrick it with the dongle? I seem to have done something similar to mine.

[yardern]

@Flopalop2 Have you got the dongle? You basiclly follow this: https://docs.qmk.fm/#/isp_flashing_guide?id=flashing-stm32duino-bootloader

[Flopalop2]

@yardern that is exactly the guide I was looking for. I have the dongle I just couldn't figure it out. Thanks!
