How to restore ios 6.0 iphone 4s?

Hello all;
I have an iphone 4s which is stuck on recovery logo(connect to iTunes screen), actually the phone was working fine on ios 6.0… Then I saw an update of ios 6.1.so I decided to install it. I click on install. The phone restarted and an apple logo appeared and underneath it was an installation bar showing the installation. Then suddenly it restarted and stuck on recovery logo. Please help… How can I reinstall again ios 6… Your answers would be warmly appreciated;

Put your phone into DFU mode. And restore It should work then.
