What is error 800700AA? - Windows Phone 7

Yesterday i was updating my windows phone but it failed through zune, dont ask me why.
Now, I am unable to even on my phone, hard reset it or anything, whenever the phone is on, after the HTC logo appears, it is the "Connect to PC" picture shows on my phone, nothing else I can do.

Thus, I try to restore it through Zune but it fails too.
It says error code 800700AA.

I am about to send back to claim my warranty on this issue, but now it is Chinese New Year and they are off, any other solutions to try at the meantime?

Much appreciated,
a HTC 7 MOZART user.

Hi JasonWilton,


Thank you for your response.


You have two options:


1. Reconnect to PC (zune software open) and leave it there for about 2-3 hours and see if it recovers,


If that is not the case


2. Contact your provider to get it repaired.


Unfortunately, there is not much else you can try as even a hard reset does not work!
