QU-24 firmware update V1_82_4387

Does any one have any problems after Qu24UpdtV1_82_4387 update?
I update my QU-24. First that looks at there are no problems but…
Middle of the next gig, I could not listen (Headphones) anymore any Mix 1 - 6 (aka monitors)? Everywhere was same mix than L+R…
Meanwhile, routing went nut… All monitors listen only Chanel 10 (this time lead vocals…)

I checked several times all routings and set up but did not found any mistake…

Am I crazy (that´s also possible…) or can be a problem with the device / firmware update?

Try a hard reset of the board. If that doesn’t fix it, do a new download of the firmware. Make sure your USB stick is one of the approved models properly formatted. It’s best to use a stick with nothing else on it and double check the formatting.
