Title: UT47.2 problem with left ctrl
Post by: envyy24 on Wed, 18 March 2020, 15:44:38

Hi all,

Somehow the left ctrl, the only control it is, in my UT47.2 registers 5 keys at once instead of 1. I tried to flash it back to default but somehow qmk does not recognize the board. When i put it in DFU mode qmk realize it but when I flash it failed. Any one had the same problem before or know how to deal with this?

Many thanks

I'm not familiar with this board but general troubleshooting applies - is the diode for that key soldered backwards or did it used to work?  Also the switch pin could be shorted to an LED pad (again, if it never worked since it was soldered)

As for the flashing actual error messages will probably help someone help you.

I think it is, im not quite sure about that (the diode)

Here is the problem I run into when flashing.

Set to dfu ok here
