LG F260S Optimus LTE III boot repair supported

Repairing bricked LG F260S 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 F260S:

•  Solder JTAG cable to LG F260S JTAG pads;


•  Insert USB Data cable into board and PC;


•  Make sure LG F260S 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

To enter emergency mode:

•  Disconnect PC cable;


•  Insert battery;


•  Hold both ‘Volume down’ and ‘Camera’ keys and press ‘Power ON’ button.
