Stem not working no lights

[mrgamingspirit]

I updated my s-tecs to v2.20c and after that my stem is not connecting anymore with the s-tecs base.
I have tried a differnt cabel and a default reset in the VKB device convig but nothing helped. It is also not showing up in the find & show tab.
It once did shortly connect but directly disconncted again.
USB-C ports should be fine nothing looks weird.

Can some maybe help with this problem?
Thanks

What firmware were you on previously?

[mrgamingspirit]

I think 2 .09. It was defenitly after the 2.0

If updating the firmware was the only change, it probably means that the new firmware has a bug. Try some older versions of firmware from here (the Firmware section).

Thank you for the files. I have tried diferent firmware files but nothing changes the problem. Also with the differnt firmware it still dosn't find the stem in the find & show.

Make sure the connecting cable is plugged in properly at both ends, then reset to default and recalibrate.
