Problems with software update A1 - due to camera being version 1.10

[StageShooter]

     

I have two Sony A1 cameras and am a PC user. One was version 1.10, one was 1.20. I have just updated the one with 1.20 to 2.02, by using the software from the Sony website (and doing the >1.35 > 2.01 >2.02 pathway). It was fairly straightforward. However I then tried to do the same for the camera on 1.10 and have fallen at the first hurdle. I cannot set the USB method to mass storage mode. The menu is greyed out. I was wondering whether there was a way of finding the upgrade from 1.10 to 1.20? That would hopefully enable me to set the correct USB storage method and allow me to upgrade. Or is there a better way of getting around this?

I have been helped by the photographer Brian Smith with this. I wanted to post it here in case anyone else was having the same problem.  He said: 

What happens when you press the grayed out setting? Does it say “This operation or setting not available as follows: PC Remote”

If so, select Menu > Network > Transfer/Remote > PC Remote Function > OFF

USB Connection will no longer be grayed out and you can proceed.
