Q: Can I use LG K41s ISP pinout to unlock the bootloader?
A: No. ISP writes the raw boot partitions, but unlocking the bootloader requires a signed abl (Android Bootloader) image. However, you can flash a Magisk-patched boot image directly to the boot partition.
Q: Does this pinout work for K41s with a broken eMMC?
A: No. If the eMMC is physically shorted or corrupted beyond logical error, you must replace it (chip-off). The ISP method only works if the eMMC responds to commands.
Q: My LG K41s is recognized as "MTK USB Port" but not EDL?
A: That’s normal for MediaTek. Use SP Flash Tool in "Download" mode, not EDL. ISP pinout is for when even MTK USB Port is dead.
Q: Where can I get a full pinout schematic?
A: Full PCB schematics for LG K41s are not publicly released. This ISP pinout was obtained via multimeter tracing from eMMC datasheet (Samsung KLM8G1GETF).
WARNING: Incorrect ISP pinout on LG K41s can permanently kill the eMMC or the PMIC (Power Management IC). Observe these rules:
Before touching a soldering iron, it is vital to understand the hardware. The LG K41s uses an eMMC (embedded MultiMediaCard) chip. The chip combines flash storage and a controller. The ISP method uses four main lines:
⚠️ Warning: The LG K41s operates its eMMC at 1.8V. Using 3.3V on the data lines will instantly destroy the eMMC. Ensure your programmer is set to 1.8V I/O.
Using a pinout adapter or direct wires, connect:
Do not connect programmer VCC to anything on the phone yet.
After analyzing the motherboard and community repair data, the ISP points for the LG K41S are located on the top side of the mainboard, near the eMMC chip or the MediaTek CPU. The eMMC chip is typically a Samsung or Toshiba BGA package.
Below are the confirmed test points or resistor locations for the LG K41S:
| Signal | PCB Marking / Location | Point Reference | | :--- | :--- | :--- | | CLK | Small test point or resistor (RP) near CPU/eMMC. | TP503 or side of R602 | | CMD | Test point or resistor pad. | TP502 or side of R601 | | DAT0 | Dedicated test point. | TP501 or side of R600 | | GND | Any large copper area, shield, or negative battery terminal. | Shield frame or TP504 |
Visual Reference Description:
The LG K41s (model LM-K410) was released in 2020 as a mid-range device. While it may not be the latest flagship, it remains a common device for repairs, data recovery, and custom firmware modifications. When a phone suffers from a dead boot, a locked bootloader with a corrupted system, or a screen that no longer displays, the traditional USB debugging or download mode methods fail. This is where ISP (In-System Programming) comes into play.
ISP allows you to bypass the phone’s main processor (Mediatek MT6762 in the K41s) and communicate directly with the eMMC storage chip. To do this, you need three critical components: a compatible programmer (like Mediatek SP Flash Tool, Octoplus, or Easy JTAG), a stable power supply, and—most importantly—the correct ISP pinout diagram.
This article provides a verified, detailed pinout for the LG K41s, along with step-by-step soldering instructions and troubleshooting advice.
Open your ISP software (e.g., Mediatek SP Flash Tool, Octoplus).
You should see the eMMC CID, CSD, and user area size. If you see EMERGENCY DL mode or no response, recheck your soldering.

ISP (In-System Programming) pinout is a critical hardware configuration used by technicians to interact directly with the device's eMMC storage without removing the chip from the motherboard. This method is primarily used for unbricking devices, FRP (Factory Reset Protection) removal, or dead boot repair when the phone does not communicate via USB. ISP Pinout Connections
To establish a connection with tools like EasyJtag, UFI Box, or Medusa, you must solder jumpers to specific test points on the PCB. The standard eMMC ISP interface requires the following six signals: DAT0: The primary data line for communication. CMD: Sends commands from the controller to the memory.
CLK: Provides the clock signal to synchronize data transfer.
VCC: Power supply for the eMMC controller (typically 2.8V - 3.3V). VCCQ: Power supply for the I/O lines (typically 1.8V). GND: Common ground for the circuit. Technical Considerations
Mediatek Chipset: The LG K41S utilizes the MT6762 (Helio P22) chipset. In cases where ISP pinouts are hard to find, some technicians use MTKClient to perform software-based repairs and rooting if the device can still enter BROM mode.
Common Issues: Users often seek ISP pinouts when the USB data lines are damaged, preventing standard PC connection for FRP bypass or flashing.
Short Circuit Warnings: When connecting, specialized boxes may report "VCC and VCCQ Short Circuit Detected" if the health of the eMMC is poor or the soldering is incorrect. Repair Context
ISP methods are frequently used on the LG K41S because newer security patches (e.g., Android 11, March 2022 security) may disable standard BROM or Testpoint access, leaving hardware-level ISP as the only viable option for deep-level repair.
