Samsung M017f Isp Pinout May 2026

The Samsung M017F ISP pinout is not merely a diagram; it is a roadmap to reviving dead devices. While the device's low cost might tempt some to replace the motherboard entirely, mastering ISP pinouts elevates a technician's capability to handle firmware-level repairs without board replacement.

Key Takeaways:

By following this guide, you can successfully unlock, revive, and repair the Samsung M017F even when all standard USB methods have failed.

Disclaimer: Modifying your device's hardware and software voids the warranty and may cause permanent damage. Proceed at your own risk. This guide is for educational purposes and professional technicians only.

After analyzing the mainboard schematics (PCB Rev. 1.0) and practical reverse engineering, the verified ISP pinout for the Samsung M017F is as follows: samsung m017f isp pinout

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 JEDEC eMMC 153-ball standard.

| Function | Pin Number (on eMMC chip) | Wire Color (Typical in ISP adapters) | | :--- | :--- | :--- | | VCC (NAND Power – 3.3V) | Pins 2, 3, 6, 7, 10, 11 | Red | | VCCQ (Controller I/O – 1.8V or 3.3V) | Pins 135, 138, 141, 144, 147, 150 | Orange | | VSS (Ground) | Multiple (e.g., 1, 5, 9, 12, 13, 17...) | Black | | CLK (Clock) | Pin 152 | White | | CMD (Command) | Pin 151 | Green | | DAT0 (Data 0) | Pin 149 | Yellow |

Typical connection sequence for ISP box (e.g., EasyJTAG, Medusa, Octoplus):

Standard Samsung recovery tools (Odin) and even the MTK Bypass Utility rely on a functional USB boot path. If the Preloader is corrupted, the PC will show “USB Device Not Recognized” or the device will constantly restart. The Samsung M017F ISP pinout is not merely

ISP programming allows you to:

Before soldering, you must locate the eMMC chip. On the Samsung M017F, the motherboard is labeled typically as SM-M017F MAIN REV1.0 or REV1.1. The eMMC is a small BGA (Ball Grid Array) chip, usually a Samsung KLM8G1GETF or Kingston equivalent (8GB eMMC 5.1).

Important: Do not confuse the eMMC with the CPU (MT6739). The eMMC is located near the SIM slot or the power management IC.

Warning: The exact coordinates of the pinouts can vary depending on the specific PCB revision. The following is the standard mapping methodology for the M017F mainboard. By following this guide, you can successfully unlock,

DO NOT connect 3.3V from your ISP programmer directly to the eMMC VCC line. The Samsung M017F’s eMMC is powered by the main board’s PMIC (Power Management IC). If you inject external power, you will back-feed the PMIC and burn the motherboard.

Correct method: Power the phone via its battery connector (3.7-4.2V) OR connect a stable 3.7V supply to the battery B+ contact. The internal PMIC will generate the proper 3.3V for the eMMC.

The ISP points for this model are located on the motherboard near the eMMC chip. Standard test points:

| Signal | Location on PCB (SM-G017F) | | :--- | :--- | | CMD | Resistor R310 | | CLK | Resistor R311 | | DAT0 | Resistor R312 | | VCC | Capacitor C500 (positive side) | | GND | Shield or capacitor C500 (negative side) |
