    I am following the information on http://blog.winkeyless.kr/183 however, I am unable to get the firmware loaded (the LEDs are blinking all the time)

    I went through the troubleshooting steps and followed the soldering guide.

    How to fix when keyboard doesn’t work after uploading firmware

    Soldering Guide


    When I click the Firm Up button it runs, briefly stops blinking and then continues to blink.

    I checked the PCB, and I get the HIDBoot item in my devices, and the LEDs are all blinking.


    I have the 4×6 layout on the b.pad.


    What am I to do next?



    The images are too large so I placed them on imgur.




    Hi, Happy New Year!!

    Sorry for your inconvenience.

    If the leds are blinking, most of the reasons are coming from bad soldering
    – electric short, wrong direction(polarity)…

    Please check solderings.

    And could you tell me whether keyboard is working?
