Lg K41s Isp Pinout New ✰

Unlike older pinouts that only force EDL 9008 (Qualcomm mode), this new pinout layout for the LG K41S introduces:

Issue: “CMD timeout error” or “No response from eMMC”
Fix: Check the pull-up resistor. Rev 1.1 boards have a weaker internal pull-up. Add an external 4.7k between CMD and 1.8V. Also, ensure you are using TP622, not the older TP609.

Issue: ISP software detects eMMC but reads only zeros.
Fix: Your D0 line may be on the wrong pad. Confirm with a multimeter that TP603 has continuity to eMMC pin 8 (DAT0). Alternatively, try D1 (TP604) as some batches remap data lines. lg k41s isp pinout new

Issue: Phone heats up when connecting.
Fix: Immediately disconnect. You have shorted VCC (eMMC power) to a data line. Remember: Never feed power into the test points – the phone supplies its own 3.7V.

The LG K41S uses a Qualcomm Snapdragon 215 (QM215) platform. The eMMC is typically a Kingston or Samsung chip (4GB/32GB or 4GB/64GB variants). There are two PCB revisions in circulation: Unlike older pinouts that only force EDL 9008

⚠️ Important: The old pinout (widely shared on forums like GSM-Forum or Hovatek) fails on Rev 1.1 with “eMMC timeout errors” because the CMD line is now pulled up to 1.8V via a different resistor. The new pinout below corrects this.

If TP501-503 are missing, use these resistor pads near eMMC: ⚠️ Important: The old pinout (widely shared on

| Signal | Component Pad | | :--- | :--- | | CLK | One side of R504 (0 ohm jumper) | | CMD | One side of R502 | | D0 | One side of R503 |

📌 Note: These resistors are typically 0-ohm links. Soldering directly to the pad is risky – use a fine tip and flux.
