Does trying to downgrade iOS void my warranty?

I have an iPhone 4S and I tried to downgrade back to iOS 6.1.3 after I updated to iOS 7.0.4 but it didn't work and it just showed an error code. Will Apple void my warranty for doing this? If so I'm only 13 so if this happens I can't afford a new one.

I stole a lot of valuable stuff, and now i can, t return it?

OK so due to recent strikes the NATO containers have been at a stand still in peshawar city so i went to that place where the containers were parked along with my cousins. As per rule we were not allowed do go near the container but my cousins knew some truck drivers who let us in, he took us in a container. Which had the most amazing stuff ever.laptops, macbookscore i series, iphones, latest, ipads, samsung galaxy tab, and many more that was for the us soldiers so we took a great amount of those things and brought them back home. I decided to sell all this stuff, but suddenly i realized i have done a bad and immoral thing i wanted to return it but now i'm out of the city and NATO SUPPLY WOULD START AGAIN. So what should i do know. Should i keep these things.
