Error 52 Update Error

Hi there,

After an update on my Iphone 5 the phone got stuck.

I've booted it into recovery mode and DFU mode, when I plug it into my macbook with the latest itunes, it recognises it and it starts to recover. However near the end when it's restoring firmware it just stops for ages. It eventually comes up with the Error 52. Please help, this is a nightmare and I'm without a phone!

Thanks
