ISP Box Pin → LG K41s point
--------------------------------
Vcc (3.3V) → C2002 (+)
GND → Shield / GND
CMD → R2011 / TP_CMD
CLK → R2012 / TP_CLK
DAT0 → R2010 / TP_D0
Once detected, you can perform the following critical repairs:
Remove the LG K41s back cover, battery, and all flex cables. Unscrew the mid-frame. Locate the motherboard and clean the area around TP502, TP503, TP504 with isopropyl alcohol. These pads are tiny—about 0.5mm in diameter.
There are three hardware variants of the LG K41s:
Good news: All variants use the motherboard revision PCB_1.3 with identical eMMC placement. The ISP test points are located on the back side of the mainboard, near the battery connector.
⚠️ Warning: Do not confuse with LG K40 (2019). That model uses a different pinout (Qualcomm SDM450). The K41s is MediaTek-based.

Finding a confirmed, publicly shared ISP pinout for the LG K41S (LM-K410)
is currently difficult, as it is not listed in standard public databases like
. Technicians often encounter issues with this specific model due to hardware variations and difficulties with connection stability. Current Status & Technical Challenges Availability: lg k41s isp pinout
Many repair communities report that there is no widely available or "official" ISP diagram for the K410HM/K41S variant. Hardware Variants:
Some diagrams found online may not match your specific board version, making them unreliable for soldering. Alternative Recommendations:
Due to the difficulty of ISP connections on this model, experienced technicians often recommend: Firmware Downgrade:
If the goal is FRP bypass, downgrading the firmware to an older security patch may allow access to without hardware modification. Removing the eMMC chip and using a socket (like
) is frequently cited as the most reliable way to read this device's memory. Typical eMMC ISP Requirements
If you attempt to find these points yourself via a board schematic or multimeter, you will need to locate: DAT0, CMD, and CLK: Data line, Command line, and Clock signal. VCC and VCCQ: Power lines (often 2.8V and 1.8V). Ground connection.
For the most up-to-date board-specific images, it is recommended to check the support forums of your specific tool, such as the EasyJTAG Support Octoplus Box Forum or specific test point locations for BROM mode instead? Lg ms330 ISP PINUOT DONE al soporte de Easyjtag
The LG K41S ISP (In-System Programming) pinout is a specialized hardware map used by technicians to interface directly with the device's eMMC storage chip. This method is essential for performing advanced repairs such as dead boot recovery, FRP (Factory Reset Protection) removal when USB debugging is disabled, and low-level data recovery. Understanding the LG K41S Pinout Once detected, you can perform the following critical
For the LG K41S (typically model LM-K410HM or LM-K410EMW), the ISP connection bypasses the standard USB port, which is often damaged or locked by software security. The connection requires soldering thin jumper wires to specific test points on the motherboard. Essential ISP Connection Points
To establish a connection using tools like EasyJtag Plus, Medusa Pro, or UFI Box, you must identify and connect the following signals: Lg K41s Isp Pinout Apr 2026
The air in the small workshop was thick with the scent of solder and determination. On the bench lay a silent LG K41s, its screen a dark mirror reflecting nothing but the technician's focused expression. A forgotten pattern lock had turned this gateway of memories into an expensive brick.
The usual tricks—holding Volume Down + Power to force a factory reset—had failed, or perhaps the data inside was too precious to wipe. It was time for the "surgical" approach: the ISP (In-System Programming) pinout.
With a steady hand, the technician removed the back cover. Under the microscope, the motherboard revealed a miniature city of silicon. To wake the sleeping eMMC chip without desoldering it, they needed to find the hidden "backdoors": CLK (Clock) CMD (Command) DAT0 (Data) VCC/VCCQ (Power)
A steady hand bridged the gap between the tiny test points and a specialized programming box. One spark of error could fry the board, but a perfect connection would bypass the software's stubborn locks. The blue light of the programmer flickered—the heartbeat of a machine coming back to life. In that silent exchange of data, the "story" of the phone was finally unlocked, piece by digital piece. Technical Reality Check
For those looking to replicate this "story" in real life, the LG K41s (LM-K410) often requires these direct hardware connections to the eMMC when software-based FRP or pattern resets fail. Key ISP Pinout Points (General Guide):
CLK/CMD/DAT0: Usually found as small copper pads near the eMMC shielding. GND: Any large metallic shield or ground plane. Good news: All variants use the motherboard revision PCB_1
VCC (2.8v) & VCCQ (1.8v): Can often be powered via the USB cable during the process to avoid risky soldering on power lines.
How to Hard Reset LG K41s – Bypass Screen Lock / Wipe All Data
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.
Apply a small amount of flux to the test points.
Tip: Do not solder directly to the eMMC ball grid array unless you have professional rework skills. The test points are designed for this.
The software detected the eMMC CID, CSD, and partitions immediately. He read the boot1 and boot2 partitions, identified the corrupted preloader, and rewrote a known-good preloader backup from another K41S.
After writing, he disconnected ISP wires, reconnected the battery, and pressed power. The LG logo appeared. The phone booted normally.
The customer was amazed. Alex saved the board from being scrapped—all because he knew where to find and how to safely use the LG K41S ISP pinout.
