Note: Exact pad labels can vary by board revision. On many K41S boards the pads are grouped near the eMMC chip; DAT0/CMD/CLK are adjacent pads, with VCC and GND slightly offset. Use a multimeter to confirm continuity to known eMMC pins before powering.

Using the ISP pinout above, you can reset FRP faster than any paid service.

Note: A "Better" alternative is to use the software's built-in "FRP Reset" button, but manual hex editing works every time the automated script fails.

This is where LG differs from Samsung or Xiaomi, and why a "better" pinout is crucial.

Simply hooking up CLK, CMD, DAT0, GND, and VCC is often not enough for LG devices. You typically need to find the DL (Download) Test Point to force the Qualcomm loader.

Most pinouts you find online are low-resolution scans from 2019. They often mislabel the Vcc (power) and VccQ (I/O voltage) lines, leading to fried eMMC chips. The LG K41S uses a 1.8V logic level (VccQ). Applying 3.3V directly to the CLK/CMD/DAT0 lines will destroy the eMMC instantly.

Here is our verified, "better" pinout.

After reverse engineering the LG K41s mainboard (disassembly code: LG-Q630_MB_V1.0), we have identified an alternative, superior set of points near the EMI shield cutout close to the CPU. These points are larger, labelled, and offer a cleaner signal.

Before we look at the pinout, let’s address the hardware. The LG K41S runs on a MediaTek Helio P22 (MT6762) chipset. This chipset has a notoriously unstable preloader mode via USB. You have likely experienced the dreaded [LIB]: (EMMC) Open data partition failed error in tools like Medusa Pro, Easy JTAG, or Octoplus Box.
