Set the voltage frequency to or manually select 1.8V for VCCQ and 3.3V for VCC .
Click . If configured correctly, the log screen will read out the phone's internal storage layout, device partition map, and build details. Safety and Troubleshooting Guidelines
Attempting to find a "new" ISP pinout is an procedure. Be aware of the significant risks:
If you are trying to resolve a simple software lock, always attempt first before resorting to an ISP procedure. Hardware modifications should only be carried out if you have confirmed that the device's USB port will not accept standard firmware flashing tools.

Open your box software (e.g., UFI Android ToolBox or EasyJTAG Plus Shell ). Step 3: Device Identification Set the Bus Width to (ISP mode always uses 1-Bit).
| | Likely Cause | Solution | |-------------|------------------|---------------| | No detection | DAT0 not connected or shorted | Re-solder DAT0; check for bridges with adjacent pin J4 (VDDi) | | Detection but "Read timeout" | CLK line interference | Shorten CLK wire to < 2cm; add a 10-22Ω resistor in series on CLK | | Device powers on during ISP | Ground missing | Ensure solid GND connection to the ISP box and phone | | RPMB error when writing | Power instability | Use a bench supply (4.0V, 2A) on battery terminals instead of battery |
: Known for its smart repair files (SRF) tailored for LG models.
: The primary path for reading and writing data. GND (Ground) : A stable reference point for the circuit. Set the voltage frequency to or manually select 1
Carefully desolder your jumper wires using a desoldering braid to leave the surface pads clean.
Because the ISP points on the LG K41s motherboard are extremely small, you must use high-quality soldering equipment to prevent damaging the circuit tracks: : Essential for visual accuracy.
The is a specialized hardware connection map used by technicians to perform low-level data operations on the device's eMMC memory chip without removing it from the motherboard. This "In-System Programming" (ISP) method is essential for repairing software-related issues such as permanent boot loops, FRP (Factory Reset Protection) removal when USB ports are damaged, and dead boot recovery.

: The components around the LG K41S processor and flash memory are highly heat-sensitive. Avoid keeping the soldering iron tip on a single point for more than 2 seconds.
The LG K41S remains a relevant repair target, but its later PCB revision has confused many technicians. Using the – specifically CLK at TP610, CMD at TP622, D0 at TP603, plus a 4.7k pull-up – restores reliable eMMC communication for FRP unlock, dead boot repair, and data recovery.
Connect your ISP adapter to your preferred eMMC software box (e.g., EasyJtag Plus or UFI). Open the accompanying software suite on your PC.
