This action is not foreseen by the Eversolo policy. Using FW of many other Android based media players doing so hardly ever created problems as a negative side-effect. One can always next do a factory reset on just the downgraded FW.
Fortunately @Remik shared us an Android developers method to bypass this limitation. All thanks' go to him
Just do one of the following:
Main Menu => Settings => About => FW revision => Revision 1.2.96 (press 7x)
Main Menu => APPs => Update...
Howto: Downgrading/reverting the FW level
