Phone heats up when connecting. Fix: Immediately disconnect. You have shorted VCC (eMMC power) to a data line. Remember: Never feed power into the test points – the phone supplies its own 3.7V.
For software-related issues, attempting an ISP pinout might be an unnecessarily complex first step. Consider these alternatives before proceeding:
The is a MediaTek-powered smartphone utilizing an eMMC BGA-221 embedded memory chip . When the device becomes hard-bricked, gets stuck in an infinite bootloop, suffers from broken USB data tracks, or refuses to enter MediaTek BGA/BROM mode for software-based FRP bypass , an In-System Programming (ISP) hardware connection is the only way to interface directly with the device's storage. lg k41s isp pinout new
Usually, the ISP points for the LG K41s are located near the EMMC chip or under a shield can. You will need to identify the following four primary connections:

The most effective path forward is to use a . The LG K41S uses the MediaTek MT6762 (Helio P22) chipset. The eMMC programming interface (the ISP bus) is often common across all devices using the same processor.

Executing an ISP connection successfully requires specialized hardware boxes paired with precision instruments to avoid frying the sensitive circuitry on the MediaTek logic board. Required Hardware Type Industry-Standard Tools Micro-soldering iron station with 0.1mm jumper wire Connecting to micrometric motherboard resistors Diagnostics / Power Variable DC Power Supply or USB Type-C Cable Injecting VCC/VCCQ voltage safely Step-by-Step ISP Connection Guide Step 1: Motherboard Extraction
Never attempt an ISP connection while the phone battery is plugged into the board. This can cause catastrophic hardware failure. Remember: Never feed power into the test points
