[HELP]WP Genesis Focus theme

I have big difficulties to add a custom header image to Studiopress Genesis Template (Focus theme). If you worked with this popular theme you know what i mean. There is predefinied the image header size to xpx x xpx and is in left corner seen on my picture. I want my logo of 1050px x 120px on full width as is marked on the image with red color.

I have already wasted 3 hours, tested all the possible things, but cant bring it to work. Now you are my last hope guys.

Have you tried going to ftp saving current default and edit that and ftp it back over?

Yes, the problem is not that i can't recovery back, the problem is, that i can't modify this damn css. This image must be there when i made this red border on provided screenshot.

Okay i have found the freakin code, it was in functions.php.

Nice you managed to resolve your issue and shared your solution with the community.
