Lg K41s Isp Pinout New Jun 2026

: Complete hardware loop circuit providing reference voltage stability.

The ISP connection requires soldering to specific test points on the motherboard to interface with the eMMC storage. Alguien Con ISP Pinout LG K410HM (K41S) Alguien Con ISP Pinout LG K410HM (K41S) LG X410UM ISP PINOUT zona-experta2017

The primary data line responsible for transferring data blocks between the eMMC and the hardware box.

Disclaimer: ISP modification requires advanced micro-soldering skills. Proceed at your own risk. Incorrect connections can permanently damage your device's motherboard.

Like VCC, this can be supplied via the phone's battery/USB interface, but direct soldering ensures a more stable connection. 6. GND (Ground)

The structural reference voltage point required to complete the circuit. VCC ( ): Core power line supplying energy to the eMMC controller. VCCQ ( : Complete hardware loop circuit providing reference voltage

Fix : Immediately disconnect power. This indicates a hardware short circuit between a power rail (VCC/VCCQ) and the GND chassis plane.

💡 Use a multimeter in continuity mode to verify. Touch ground, then probe the pad – CLK, CMD, and D0 should show no short to ground, and resistance to ground ~500-700Ω.

⚠️ The old pinout (widely shared on forums like GSM-Forum or Hovatek) fails on Rev 1.1 with “eMMC timeout errors” because the CMD line is now pulled up to 1.8V via a different resistor. The new pinout below corrects this. Carefully solder thin jumper wires to the points

Whether the phone is completely dead or stuck on the .

Immediately read and save the Boot1 , Boot2 , and User Area (dump file). Always backup the NVRAM and NVDATA partitions to preserve the original IMEI and network calibration data.

To interface directly with the device's , you must safely remove the motherboard from the chassis, shield it from static electricity, and gently scrape away any protective black glue or thermal shielding overlying the target traces.

| ISP Function | Pad Location on PCB (Rev 1.1) | Voltage Level | Color Code (Typical Wire) | |--------------|-------------------------------|---------------|---------------------------| | | Slightly right of the eMMC, pad TP610 (near a tiny 0Ω resistor). | 1.8V | White | | CMD | Below the CPU shield corner, pad TP622 (do NOT use old TP609). | 1.8V with 4.7K pull-up required | Yellow | | D0 | TP603 – clear test point southwest of eMMC. | 1.8V | Orange | | GND | Any large copper area or the battery connector negative terminal. | 0V | Black | | VCC (eMMC power) | Do not connect externally; phone’s battery or DC supply must power the board (3.7V–4.2V). | n/a | n/a |
