  •  Solder JTAG cable to LG P999 Modem JTAG pads;
  •  Insert USB Data cable into board and PC;
  •  Make sure LG P999 Modem is selected in the list of models;

  •  Wait till software signals a successful operation completion;
  •  Disconnect power supply, de-solder JTAG wires;

Now phone is in bootable condition, that is, even if it does not start up normally, you can flash it using known flashing methods.
