Hi,

I want to downgrade to iOS 18.5.
I have the 18.5 IPSW file, is it enough to connect the phone to my Mac and option-click restore and select the .ipsw file?

Also I'm using Vodafone UK, will I lose my eSIM?

Thanks

You’ll need to put your device in recovery mode mode and do it.

You won’t lose your eSIM.
