Lg K41s Isp Pinout Better Fix May 2026

Do NOT inject external voltage into VccQ. The LG K41S internal PMIC (Power Management IC) provides clean 1.8V to the eMMC I/O. Let your ISP box sense the voltage via the pin if your box supports it (e.g., Medusa Pro's automatic voltage detection). If your box forces 1.8V output, connect to TP505 (VccQ sense), but never apply 3.3V here.

To provide the most accurate visual for your specific board revision, could you tell me: What is the on the back (e.g., K410HM)? Which flashing tool are you using (EasyJtag, UFI, Medusa)? Do NOT inject external voltage into VccQ

: If the ISP method fails, you may need a "chip-off" approach using a BGA 221 socket . ❓ Troubleshooting "No Connection" If your software (e.g., EasyJtag) does not detect the eMMC: Lower the Frequency : Reduce the CLK speed to 1MHz or 5MHz. Verify Voltage : Ensure VCCQ is receiving a stable 1.8V. If your box forces 1
