K41s Isp Pinout — Lg
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.

The LG K41S (specifically model LM-K410) utilizes an eMMC-based storage system that can be accessed via ISP (In-System Programming) for advanced repairs, such as FRP (Factory Reset Protection) removal or data recovery, when standard USB methods fail. Essential ISP Connection Points
To connect the LG K41S to a programming box like EasyJtag or Medusa, you must solder jumpers to the following minimal pinout points on the motherboard:
DAT0: The data line for transferring information between the CPU and eMMC.
CMD: The command line that sends instructions to the storage chip. CLK: The clock line that synchronizes data transfer. GND: Common ground connection. VCC (2.8V - 3.3V): Main power supply for the eMMC chip. VCCQ (1.8V): IO power supply for the eMMC interface. Hardware & Repair Context The LG K41s (model LM-K410) was released in
BGA Compatibility: The LG K41S typically uses a BGA-221 eMMC chip. Some technicians recommend a "chip-off" method (removing the chip entirely) if the ISP connection is unstable or if the board is heavily damaged by water.
Software Tools: Common tools used for this procedure include EasyJtag Plus and UnlockTool, which support the K410 series for bypass and flashing operations.
Alternative Methods: If the USB port is functional, many users prefer using Brom Mode or specific Testpoints to avoid soldering, though these may be patched on newer security updates like Android 11.

To successfully read/write via the LG K41s ISP pinout, prepare the following:
| Tool | Recommended model | Purpose | |------|------------------|---------| | ISP programmer | Easy JTAG Plus or Medusa Pro II | Interface between PC and eMMC | | Soldering workstation | 858D hot air + TS100 iron | 330°C for wires, 280°C for ground | | Microscope | Andonstar AD407 | Identifying 0402 resistors | | Tweezers | ESD-safe, ceramic tip | Placing ISP cable | | Wiring | 30AWG Kynar or silicone | Prevents pad lifting | | Software | SP Flash Tool v5.2144 or Easy JTAG Flasher | Partition read/write | | Preloader | LGE_K41s_preloader.bin (extractor from KDZ) | Boot repair |
Important: Do not use alligator clips or pogo pins. The LG K41s ISP points are too small. Direct soldering is mandatory.
If detection fails, re-check CLK and CMD soldering – these are the most fragile.
