: The primary path for reading and writing data. GND (Ground) : A stable reference point for the circuit.
When soldering directly to delicate surface-mount components, keep your soldering iron temperature around 300°C–330°C. Prolonged heat can easily shift or lift tiny resistors off the logic board.

Before we get into the methods, it is important to address the most straightforward path to the correct diagram. : The primary path for reading and writing data
In these videos, you will not see an animated diagram or a flat schematic file. Instead, you will see the technician mounting the motherboard under a microscope, soldering wires to specific, tiny points, and then connecting them to a UFI or Easy JTAG box. Your task is to pause the video at the critical moment and visually match those points to the ones on your board.

Solder a thicker secondary GND wire; drop the interface bus speed down to Damaged partition headers or corrupted boot configuration.
The new LG K41S ISP pinout is significant for several reasons:
Located on a tiny resistor track right next to the eMMC perimeter shield.
The clock frequency is too high for the thin jumper wires. Reduce the bus speed to 9 MHz inside the software configuration panel and try again.
