First of all - so you know.. My english is terrible =)

I bought a Iphone 3Gs and had it for a cuople of weeks..
But when i should install the latest firmware it got stuck at 70 %.
I left it there for 18h but it was still att 70'%.

I pulled out the cable and now I cant make it start?
If i connect it to Itunes it tells me that Iphone is in recovery mode..

But i cant finish the recovery and Itunes tells me that an error 1611.

What should i do?I have tried to download i earlier firmware but it not working..

Help anyone??
