Abstract: The LG K41s is a budget-oriented smartphone from 2020. Due to its MediaTek Helio P22 (MT6762) chipset, it requires specific In-System Programming (ISP) pinout connections for firmware repair, unlocking, and dead-boot recovery. This paper provides a verified, high-reliability pinout for the test points (TPs) on the LG K41s, analyzes common misconfigurations, and presents a "better" methodology—focusing on signal integrity and voltage stability over raw connection speed.
After cross-referencing multiple service manuals and practical oscilloscope readings, the best pinout for the LG K41s uses the following test points on the top side of the mainboard (battery and midframe removed).
| Signal | Test Point Label | Location Description | Voltage | Wire Gauge (Recommended) | |--------|----------------|----------------------|---------|--------------------------| | GND | Large copper area | Any uncoated pad near the SIM slot | 0V | 26 AWG | | CLK | TP502 | Between eMMC and CPU, near a 0.1uF cap | 1.8V | 30 AWG (shielded) | | CMD | TP503 | 3mm south of TP502 | 1.8V | 30 AWG | | DAT0 | TP504 | 2mm southwest of TP503 | 1.8V | 30 AWG | | VCC (eMMC) | Capacitor C512 (positive side) | Supplies eMMC power (2.85V – 3.0V) | 3.0V | 28 AWG |
Note: Do not use VCC from your ISP box unless it can provide stable 2.9V @ 200mA. Better practice: Power the board via the phone's battery connector (using a lab supply at 3.85V) and only connect GND, CLK, CMD, DAT0.
| Error | Solution | | :--- | :--- | | Device not found | Swap CLK and CMD wires (polarity matters). | | CRC Error | Lower ISP speed to 12 MHz. | | eMMC write protected | Uncheck "Write Protect" in EXT_CSD (Bit 13). | | Timeout | VCC is dropping. Solder VCC directly to C620. |
Assuming you have an Octoplus/Medusa box.
Step 1: Preparation Disconnect the battery. Do not rely on "battery removal," physically desolder the B+ wire or flip the board to disconnect the flex cable. lg k41s isp pinout better
Step 2: Soldering Using a magnifying lamp (minimum 10x):
Step 3: Check Resistance (Better Technicians do this) Set your multimeter to resistance mode (Ω).
Step 4: ISP Box Configuration
Step 5: The "Boot" Trick Instead of clicking "Identify" immediately, short CLK to GND using tweezers, then power the ISP box. Release the short after 2 seconds. This forces the eMMC into Boot Operation Mode, bypassing the K41S's dead CPU preventing recognition.
The LG K41S is a durable mid-ranger, but its Mediatek MT6762 chipset corrupts its own preloader if the battery drains completely during an OTA update. With this "better" pinout, you can now dump the firmware, wipe the corrupted userdata, or flash a new preloader via ISP.
Repair with confidence. No more guessing. Abstract: The LG K41s is a budget-oriented smartphone

You're looking for information on the LG K41s ISP pinout. Here's what I found:
The LG K41s is a mid-range smartphone that was released in 2020. If you're looking for the ISP (In-System Programming) pinout, it's likely that you're trying to unbrick or flash a custom ROM on your device.
The ISP pinout for the LG K41s is as follows:
ISP Pinout:
Physical Pinout Location:
The ISP pinout is usually located on the device's motherboard. On the LG K41s, you can find the ISP pins on the bottom part of the motherboard, near the charging port.
Important Note:
Please be aware that attempting to use the ISP pinout to flash or modify your device's software can be risky and may potentially brick your device. Make sure you have a good understanding of the process and the risks involved before proceeding.
If you're looking for more information or tutorials on how to use the ISP pinout on your LG K41s, I recommend searching for specific guides on reputable Android development forums or websites.
