Ok I’m having a similar problem, I’ve followed the steps, uninstalled Icue, downloaded the 2 files, did the pin thing and swapped over the bin files, installed the earlier Cue, but the earlier version of cue won’t recognise that I’ve wirelessly connected the K63, when I plug in the cable it picks it up, without the cable attached and with the dongle in the keyboard works fine it’s just not getting recognised in Cue, which in turn won’t let me flash the firmware as it says it needed to be connected wirelessly as well as have the cable in, have any of you had this problem?
