A: Full PCB schematics for LG K41s are not publicly released. This ISP pinout was obtained via multimeter tracing from eMMC datasheet (Samsung KLM8G1GETF). Conclusion The LG K41s ISP pinout is a lifesaver for technicians facing dead boot, QDLoader 9008 error, or eMMC corruption. By soldering to CLK, CMD, D0, VCC, and GND, you bypass the dead MediaTek processor and gain direct low-level access to the storage chip. This guide provides verified points and practical steps to recover bricked devices without removing the eMMC.
