K41s Isp Pinout New - Lg

Finding a verified LG K41S (K410HM) ISP pinout is notoriously difficult because the device often requires a

RAM Overlap: Some versions of this board have the RAM layered directly over the CPU or memory, making direct ISP connection points nearly impossible to reach without desoldering. lg k41s isp pinout new

method (removing the BGA-221 memory chip) for direct eMMC access. However, if you are performing a manual trace or using a tool like Easy-Jtag Plus Finding a verified LG K41S (K410HM) ISP pinout

, here is the technical breakdown of the necessary connection points. Required Connection Points (eMMC ISP) Box CLK → Phone CLK Box CMD →

1. GND
2. D+ (USB)
3. D- (USB)
4. 1.8V UART_TX
5. PBI (Pre-Boot Interrupt)

• Box CLK → Phone CLK
• Box CMD → Phone CMD
• Box DAT0 → Phone D0
• Box GND → Phone GND

Use Short Wires: Keep ISP wires under 10cm to prevent data noise.

DAT0 (Data Line 0): The primary path for reading and writing data. GND (Ground): A stable reference point for the circuit.

Important: Connect a 4.7k resistor from the phone’s CMD line to a 1.8V reference point (find a capacitor near the eMMC that reads 1.8V when the phone is powered).

Power the phone motherboard via its battery connector (3.8V DC power supply set to 1A current limit). Do NOT power from the ISP box’s VCC.
