Moreover i suppose factory reset doesn't works properly

i'v already tried to update prev. versions, still same problem, then i'v tried do this throught my smartphone and same stil...

Installing factory update doesn't helps

Here you can listen to this...

Yes, with all effects off - same thing. I'v tried different updates for firehawk - still the same. Another thing is when i'm trying to restore to factory settings - on launch>display i see things like Version of update>>>Restore to Factroy>>>Starting... and then nothing happens, just turning on first preset and thats all... Or this thing means that reset has been successfull? p.s. Moreover on different bank presets - noise sounds something different

After updating from factory to 1.30 i''v got horrible background noise on my firehawk device (i'v test all ports, same problem there)... Is there any reason for this?
