On the of the PCB, near the eMMC, you will see three tiny gold pads arranged in a row:

: Solder thin jumper wires (typically 0.1mm) to the CLK, CMD, and DAT0 points. You can often power the board using a USB cable instead of soldering VCC/VCCQ to avoid thermal damage. samsung m017f isp pinout

The Samsung model number M017F is not a standard consumer model number (like the Galaxy A series or Tab series). It most likely refers to a flash memory chip (eMMC or UFS) found inside a Samsung device (possibly a Gear S2/S3 smartwatch or a feature phone), or it could be a typo for a common phone model such as the SM-G017F (Galaxy J1 series).

For three hours, Jae mapped the constellation. He discovered the M017F had a trap: the manufacturer had swapped the traditional DAT0 and DAT1 pins, a silent ambush for any hacker following old Samsung schematics. Worse, the VCC pin was flanked by two "decoy" pins that, if probed simultaneously, would trigger a self-destruct fuse, melting the internal bootloader. It most likely refers to a flash memory

On the Samsung M017F motherboard, the eMMC test points are always clearly labeled on the PCB silkscreen. However, they are typically clustered near the eMMC chip itself or in a dedicated grouping of golden contact pads.

When performing ISP, you connect directly to the eMMC chip on the motherboard without desoldering it. The chip markings usually read "Samsung" with "M017F" as the part of the date/lot code, but the pinout follows the .
