12.10.2013  RIFF JTAG – Easy boot repair LG F220K (Optimus GK) supported

Repairing
bricked LG F220K with the RIFF Box requires non-beginner soldering
skills (since JTAG pads on board are very small and are close to each
other).
Phone is auto powered on with USB Data Cable connected to
the PC while battery is inserted. Please note, battery must be charged.
If battery is not charged enough there is chance of getting 0×42 error
during connection stage.

To resurrect LG F220K:

•  Solder JTAG cable to LG F220K JTAG pads;


•  Insert USB Data cable into board and PC;


•  Make sure LG F220K is selected in the list of models;


•  Click Resurrect button;


•  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.
