I failed on root. My brand new Moto X has been hardbricked. topic

Yesterday I tried to root my phone but after do all the steps that were on the sites, I couldn't turn it on anymore. Everytime I try it makes the bootloader but when it ends, the moto x turns off again. I don't know what happened someone told me that it names hardbrick so, can anyone tell me how to fix it? Or if it's possible.
If you need some information to help me, just ask.
