ahora el equipo no prende esta pegado en el logo de LG al intentar de nuevo el proceso me cobra otros 10 creditos

Answer 1

1. You need connect phone direct to mother board. Dont use any hub or box for connections.
2. You need download and install latest LG driver ( http://tool.lime.gdms.lge.com/dn/dow...=UW00120120425 )
3. After this put phone in download mode and repeat unlock/repair operation

 

Also: 

If your phone stuck on logo you need connect phone to USB cable, press and hold Vol - button and Power ON button. When phone start reboot you need unhold all button and press Vol + button and wait download mode screen. After this you can repeat unlock/repair operation
