. Technicians must typically locate and solder five essential points: Data line 0. CMD: Command line. CLK: Clock line.
Do NOT inject external voltage into VccQ. The LG K41S internal PMIC (Power Management IC) provides clean 1.8V to the eMMC I/O. Let your ISP box sense the voltage via the pin if your box supports it (e.g., Medusa Pro's automatic voltage detection). If your box forces 1.8V output, connect to TP505 (VccQ sense), but never apply 3.3V here. lg k41s isp pinout better
