Extracting critical user data (like photos or contacts) from a motherboard that has physical damage but a functional eMMC chip.
This guide provides the In-System Programming (ISP) pinout details for the (model samsung m017f isp pinout extra quality
Pinout verified from service manual and real-world repairs (as of 2025). Always re-verify with multimeter on your specific board revision. Extracting critical user data (like photos or contacts)
To minimize thermal stress on the board from soldering power lines, you can omit the VCC and VCCQ wires. Instead, connect a standard USB cable to the device's charging port during the procedure to supply the necessary logic voltages. Step-by-Step Hardware Jumper Process To minimize thermal stress on the board from
An In-System Programming (ISP) pinout is a mapped set of microscopic connection points on a smartphone’s printed circuit board (PCB). By soldering tiny jumper wires directly to these test points, hardware technicians can interface with the onboard eMMC memory chip without physically desoldering the chip from the motherboard.
: Start low at 1 MHz or 2 MHz (higher frequencies like 24 MHz often cause data corruption over long jumper wires)
Carefully remove the back cover, disconnect the battery, and extract the main logical PCB board from the housing chassis.
