Hello.

Unfortunately not all of necessary pins for eMMC (ISP) connection are present on this device PCB, so it is necessary to remove eMMC chip from PCB for repairing. Remove eMMC form PCB, connect it via soldering necessary wires to chip contacts or use proper eMMC adapter and do "Factory Repair" using the latest original LG firmware for this device model. Then solder eMMC chip back to PCB.
