When I read the explanation its normal to leave out tops when checked
 

For now it seams the update worked 
 
I'm printing the second print in a row without an error.
also I went in to the maintenance menu and checked the noise level but it was at 2.47.
This shouldn't trigger any error.
 
I fully understand that the data that the sensor is sending out isn't affected by the firmware, but the way it is interpreted is.
for now it seams that upgrading to 8.1.1 worked let hope it stays that way.

@MariMakes: be careful with the freezer, it can chip your glass plate because it can not keep up with the shrinkage.
the fridge for 10min is a better option. 
 
@oakcreeklibrary getting a spray with some water should also help with getting a pva print of the plate.
