Unhappy [Q] Help! Unbrik Zte V790 (Movistar Motion) RED Led

first of all I apologize for my bad English. and hello!

My problem is this: Try to install a rom not compatible with my ZTE V790 so I remain bricked. Just turn on the red LED. I can not get into recovery to install roms. And all I find roms are designed to be installed by the recovery. I can enter DFU mode, but do not know that I can do with that. I will be really grateful to the help they can give me. Thank you.
