Issues with SXmini Q Class. Settings error!

[Aronnok]

Hi,
Since this morning I am facing an weird problem with my newly bought SXmini Q class mod.
The issue is, when I connect the device to SXi-Q, it doesn't show any curve like before.
Sometimes the curve appears for half a second only. Rest of the time it's just flat line.

Any help in this regard will be highly appreciated.
Or, can anyone put a link for the default profiles / firmware?

I am using SXi-Q V - 2.8.1.7
Chip - SX450J v - 1.090

I am really frustrated at the moment. Please help - if you know the solution.

Very Best Regards,
Aronnok
