Hello Mattrjc,

If the issue continues, follow the guidance listed here: If you can't update or restore your iPhone or iPod touch

We hope this helps.

Thanks for using Apple Support Communities. Have a good one!

Had the same error. Multiple times. Restarted etc., but what finally worked was simply removing a bunch of music from my phone to free up memory. I wish rather than saying "an error occurred downloading..." it actually said "not enough space dude." :)

Freeing up memory worked. Update installing now.
