Help! X-Pro 2 power and shutter release broken

So I've just arrived in Bali and my X-Pro 2 bounced off the bed and my power switch / shutter release fell out. Looks a bit busted inside. Happy days.

I can power it on by sticking something sharp in it but it won't stay on. If I could keep it powered up then I could trigger using my phone.

I can't find any way to power it on remotely or trigger the shutter with another button.

Any suggestions for a workaround until I get home?

Thanks in advance, hoping for a miracle...
