I am typing on my Ducky Zero DK2018 keyboard. Three days ago, I noticed the Num Lock, Caps Lock and Scroll Lock lights were all flashing. Plugging it into a different USB port didn't help. After doing a few minutes of researching, I found that this is a common problem for a few Ducky keyboards and the fix is to update the firmware. The firmware wasn't too hard to find but I had to dig a little to find the updater tool.
Here's a zip file of the firmware updater tool and the firmware that I used. If you need a different version of the firmware, you can get it from Ducky's old site.
After I plugged the keyboard in and opened the tool, the device was showing "ISP Mode", so there was no choice for my keyboard. I then checked the current firmware version by clicking the firmware button on the right. It showed B1886V14. I figured it looked close enough to the firmware that I was going to flash it with (L1886V25), so I pressed the Download button to start the update. When it is finished the correct keyboard DK2108 is showing in the Device section and the keyboard is back to normal, hopefully for many years to come.
