XT-925 bricked during installation of carbon topic

Hi!
I was trying to install the carbon rom on my RAZR HD with TWRP recovery, i did all the wipes and installed the rom but i think i just bricked the phone cause when it boots go to recovery screen. Now i'm trying to install the retail ROM via RSD and i just can't cause im getting an error (boot_signed, on the step 13) im desesperated. Any help? I did'nt found any similar errors. thank you
