The ISP (In-System Programming) pinout for the LG K41S (LM-K410, LM-K410HM) is essential for technicians needing to perform FRP (Factory Reset Protection) removal, bootloader unlocking, or data recovery when standard USB connections or Brom mode fail. ISP Pinout Configuration
The LG K41S uses an eMMC (BGA 221) memory chip. Technicians frequently request these specific connection points for tools like EasyJtag, Medusa Pro, or Mipi Tester. CMD: Connect to the command line test point. CLK: Connect to the clock line test point. DATA0: Connect to the data 0 line test point.
VCC / VCCQ: Recommended settings are typically 2.8V and 1.8V respectively. GND: Secure to any large ground pad on the motherboard. Alternative: Brom Mode (No ISP Required)
Recent reports suggest that for many FRP and software tasks on the LG K41S, ISP may not be necessary if the device can be forced into Brom Mode:
Unlocktool Method: Some versions allow FRP removal by selecting the model in Unlocktool and holding the dedicated Google Assistant button while connecting the USB cable to trigger Brom mode. lg k41s isp pinout new
Firmware Downgrade: If the security patch is too high (e.g., Android 11), a firmware downgrade may be required to enable Brom mode or Test Points. Known Challenges
Hardware Damage: ISP is often the only resort when the USB data lines or the FPC charging connector are physically damaged.
Security Patches: Devices with security patches from 2022 or later may disable standard Test Point or Brom mode access, making ISP the standard "last resort" for professional technicians.

The LG K41S (model code LM-K410) is a budget-friendly smartphone from 2020. While it lacks the premium features of flagship devices, it is still a common unit in repair shops for tasks like:
If you have tried using standard ADB or download mode tools, you know that many K41S units enter a deep “Qualcomm HS-USB QDLoader 9008” mode but fail to cooperate with ordinary software. This is where ISP (In-System Programming) comes in.
Over the last six months, updated pinouts have emerged because LG’s later production batches moved certain test points or changed resistor configurations on the PCB. The old pinouts no longer work reliably. This article provides the new, verified ISP pinout for the LG K41S. Introduction: Why the LG K41S Needs a New
If you want the exact ISP pad labels and a boardview for your specific LG K41S motherboard revision, tell me whether you have the board's model number or upload a clear photo of the PCB around the charging port and test pads; I’ll identify pads from the image.
| Feature | Old Pinout (Rev 1.0) | New Pinout (Rev 1.1) | |-----------------|----------------------|------------------------| | CLK location | TP611 | TP610 | | CMD location | TP609 | TP622 | | D0 location | TP603 | TP603 (unchanged) | | Pull-up required? | No (internal 50k) | Yes (external 4.7k) | | Success rate | 30% (unstable) | 95% (stable) |
If soldering is not your forte, consider these alternatives:
However, for dead boot scenarios, ISP remains the most reliable method.
