Here’s a draft for a forum or blog post regarding the LG K41s (model LM-K410) ISP pinout.
It assumes you’re looking to identify the ISP (In-System Programming) / emmc test points for unbricking, dead boot repair, or direct flashing via an ISP box (Easy JTAG, Medusa, Octoplus, etc.).
If you ever need to recover a dead LG K41S (LM-K410): lg k41s isp pinout
Important: Do not use alligator clips or pogo pins. The LG K41s ISP points are too small. Direct soldering is mandatory. Here’s a draft for a forum or blog
Future Work: Future research can focus on exploring other aspects of the LG K41S, such as its bootloader, kernel, and rooting mechanisms. Additionally, researchers can investigate the application of ISP pinout in other smartphone models and embedded systems. Section 10: Safety Precautions WARNING: Incorrect ISP pinout
Standard USB flashing had failed. The bootloader was locked tight, and the device refused to communicate with the world. Leo knew there was only one way into the heart of the machine: ISP (In-System Programming).
| Signal | Point name / location | |--------|----------------------| | CMD | R2011 (or CMD test point near eMMC) | | CLK | R2012 | | DAT0 | R2010 | | Vcc (3.3V) | Capacitor C2002 (positive side) | | GND | Any shield or test point marked GND |
WARNING: Incorrect ISP pinout on LG K41s can permanently kill the eMMC or the PMIC (Power Management IC). Observe these rules:
