Failed to connect to iXpand Drive iPhone 7 and iPad Air 1,iOS 11

Hi,

I have a similar issue, but the suggested solution will no longer work for me as Apple already stopped signing iOS 10.3.3 therefore downgrade is no longer possible. Any other possible workaround for this issue?

I’m hoping you could help me. Thank you.
