SKY04O Pro - Issues and firmware

I'm convinced that there's something not quite right with the steadyview mode on my goggles.

In MIX1/2/3 I get a generally better signal, but if it cuts out at all then it doesn't come back. In diversity mode it's a poorer image, but any loss of image isn't permeant.

The manual has this

If FW1: Start with V1.3.9, means V1 hardware

If FW1: Start with V2.3.9, means V2 hardware,

If FW1: Start with V3.3.9, means V3 hardware

I have

FW V1.1.4    
FW2 01.01.00.00    
HW1.1.3

The latest firmware appears to be 1.1.3 but even then I can't actually get into the mode where you'd update the firmware

1 Connect goggles to the computer.

2 Hold the left wheel then turn on the goggles, the usb cable will power the goggles, release the left wheel, computer will automatically install the driver , computer will show a new removable storage .

3 copy the Firmware(A/B) File to stortage. goggles will installing the update at the same time

Finally there's sections on updating the DVR firmware and the receiver firmware.

I'm at a loss to determine

1. What versions of firmware I'm actually running for each item

2. If I even need to update the firmware on anything
