If the device is not FRP locked, you can perform a standard hardware reset. LG's official guide
ISP pinout refers to the specific test points printed on the phone's motherboard. These points provide direct access to the internal communication lines of the storage chip. The three critical signals are:
In-System Programming (ISP) allows you to bypass the faulty processor and connect directly to the eMMC storage chip by soldering thin wires to specific test points (TP) on the motherboard.
If you need the , reply with your board revision (e.g., REV 1.0 , REV 1.1 ) – LG sometimes moves ISP pads between revisions. lg k41s isp pinout
If your programming tool (like EasyJtag or UFI Box) detects the eMMC but reads only zeros, verify the DAT0 line. Some board batches may require using D1 (TP604) instead.

Step-by-step instructions for a system-level reset (if you have the passcode) are available via Videotron's K41S support page Are you trying to bypass a Google FRP lock or are you attempting a full bootloader repair
method (removing the eMMC memory chip) for this specific model rather than ISP. If the device is not FRP locked, you
Locate the eMMC chip (usually a Toshiba or Samsung BGA package). Immediately adjacent to the chip, you will find small, unlabeled circular copper pads. Here is the mapping:
If soldering to micro pads is beyond your skill level, consider these alternatives:
By connecting a compatible ISP programmer (like Easy JTAG, Medusa Pro, Octoplus, or an SPI flasher) to these points, you can bypass a corrupted bootloader, resurrect a dead device, or perform a low-level wipe. The three critical signals are: In-System Programming (ISP)

Because official LG service manuals are rare, technicians rely on community-verified points often found in professional software like Borneo Schematics . The following points are essential for a successful connection:
