Any way to rollback my phone?

So, thought I'd upload some photos I took last night onto my laptop. Computer and Link failed to recognise my phone & kept getting messages to update both Link and my software on my phone.

Backup wouldn't work and now because I updated my phone it has been rolled back to the factory settings & I have lost everything. Please keep the recriminations to yourselves, I know how stupid I've been. I just would like to know if this can be "undone"? Not holding my breath, though.

Thanks for any help you may have!
