Channel faders stop working Prime4+

Hello, after few days after updating to 4.2.0 firmware, the channel faders went crazy. Now the channels 1 & 2 only works with channel faders 3 & 4. everything else is still in the right channel like EQ, meters etc. When using Channel 3 & 4 in USB mode, then audio from 1 & 3 are mixed in the same channel fader and the same in the other side. I tried downgrading to 4.1 and the issue persists, so I am assuming is a hardware issue. I opened a support case, this device has literally 5 weeks since I bought it, and I would expect the support team can help me faster and eventually replace the defected device.

Hi @Carlos_Mayol

Try maybe a factory reset, and also try the following manipulation:

Unplug the unit and hold the power button for 30 seconds then release.

Replug and restart the unit.

Also try downgrading to a version 4.0 or earlier to see if that helps. If it does from then update to a version 4.2.0 from a USB media.

Hello I did try to reset to factory defaults and nothing has changed. I downgraded ti previous version where the device was previously working fine

I don’t see why another version will make a difference, is an explanation to try another release?

I am actually very disappointed with the customer service at this point
