MOD DUO X LE and XF4

Recently I did an update on my DUO X LE with the latest fw v1.13.5 and first time booting the Controller XF4 was detected, and I could assign the switches in the Web-GUI, but after second booting, “no Control Chain device connected”. The XF4 has fw 0.4.1
any hints?

Just as a troubleshooting idea, have you tried to roll back the MOD Duo X LE update and check if the problem is still there?
Maybe it was only a coincidence.

How do I do roll back?
With the fw before the update the XF4 did not work…

Sorry the late reply!

Download the image from here for an earlier OS and then you need to do a manual update (explained below the list of images)

…as I wrote the XF4 did not work reliable with a DUO X LE, regardless of the fw, I give up.
