Samsung M017f Isp Pinout Guide

On the Samsung M017F motherboard, the eMMC test points are not 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.

Consulting the official pinout for the Samsung M017F, the connection sequence to your programmer is critical.

[Motherboard]                       [ISP Programmer]
    TP_CLK   --------------------->  CLK (Pin 2)
    TP_CMD   --------------------->  CMD (Pin 3)
    TP_DAT0  --------------------->  DAT0 (Pin 5)
    GND      --------------------->  GND
    VCC (3.3V) ------------------->  VCC (Only if board is unpowered)

Expert Warning: Do not connect VCC (3.3V) from the ISP box while the device battery is connected. You risk burning the eMMC's internal voltage regulator. The safest approach is powering the motherboard via its own battery connector (using a DC power supply set to 3.8V, current limited to 1A) and connecting GND, CLK, CMD, and DAT0 only.

The Samsung Galaxy A02s (Model Code: SM-M017F) is a widely used budget smartphone. In the world of mobile repair and forensic data recovery, "JTAG" is largely obsolete, having been replaced by ISP (In-System Programming).

ISP allows technicians to communicate directly with the onboard eMMC flash memory without fully disassembling the chip. This is critical for:

In the world of mobile device repair and data recovery, the Samsung M017F (often referenced within service manuals as the SM-M017F or internal codenames like m01q) presents a unique challenge. As an entry-level Galaxy M series device, it is widely used across Southeast Asia, the Middle East, and Latin America. Consequently, technicians frequently encounter this model for dead boot, FRP (Factory Reset Protection) lock, IMEI repair, and software corruption issues.

However, unlike flagship models that support standard EDL (Emergency Download Mode) or easy UART access, the Samsung M017F MediaTek (MTK) based motherboard often requires ISP (In-System Programming) pinout to interface directly with the eMMC (embedded Multi-Media Card) chip. This article provides an exhaustive breakdown of the Samsung M017F ISP pinout, tools required, and step-by-step procedures.

The ISP connection allows direct communication with the eMMC memory chip, bypassing the primary CPU bootstrap. The following pins are required for operation:

Samsung Galaxy M01 (SM-M015F) is a common model for which ISP (In-System Programming) pinouts are sought for data recovery or firmware repair

. Note that the specific model identifier you provided, "M017F," does not exist in standard Samsung production; it is most likely a typo for the SM-M015F ISP Pinout (eMMC) samsung m017f isp pinout

To connect the device to an eMMC box (such as EasyJTAG, UFI Box, or Medusa Pro), you must solder to the following points on the motherboard: : Data line 0 : Command line : Clock line VCC (2.8V) : High voltage supply (often provided via USB) VCCQ (1.8V) : Low voltage supply (often provided via USB) Hardware Connection Tips Direct Solder

: High-resolution diagrams showing the exact resistor or test point for each line are typically found on specialized forums like or within the software libraries of Borneo Schematics Estech Schematics

: Many technicians prefer to power the board using a USB cable while connecting only DAT0, CMD, CLK, and GND to the ISP adapter to avoid complex soldering of the VCC/VCCQ lines. Resistance Check

: Ensure wires are as short as possible to maintain signal integrity for the CLK line. Important Note on "M017F"

If you are specifically looking for a model "M017F" that is not the standard Galaxy M01, double-check your device's Download Mode Settings > About Phone

to confirm the model number. If it is a regional variant, the pinouts may differ slightly based on the PCB revision. specific PCB locations for these solder points on the SM-M015F board?

The Samsung Galaxy M01s (SM-M017F) uses an eMMC storage chip, and its ISP (In-System Programming) pinout is commonly used for tasks like data recovery, unbricking, or removing locks via JTAG boxes like EasyJtag Plus, UFI Box, or Medusa Pro. ISP Pinout Connections

To establish a successful connection, you typically need to solder jumpers to the following points on the motherboard: DAT0: Data line 0 CLK: Clock signal CMD: Command signal VCC (2.8V): Power supply for the eMMC controller VCCQ (1.8V): Power supply for the I/O lines GND: Ground (can be soldered to any large metal shield) Implementation Tips

Voltage Requirements: If you are using a USB cable to power the device during the process, you may only need to connect DAT0, CLK, CMD, and GND. However, for a more stable connection, providing VCC and VCCQ directly from your interface box is recommended.

Wire Length: Keep your jumper wires as short as possible (ideally under 10cm) to prevent signal noise and data corruption. On the Samsung M017F motherboard, the eMMC test

Visual Guide: You can find high-resolution reference images for the exact solder points on the Technical Mobile and PC Solution Facebook page.

Caution: Solder work on these tiny test points requires a steady hand and a fine-tip soldering iron. Bridging these points can permanently damage the CPU or eMMC. Technical - Samsung M01s ( M017f isp pinout - Facebook

The Samsung Galaxy M01 Core (SM-M017F) is a popular budget device that occasionally encounters software bricks, locked bootloaders, or encrypted data issues. When standard USB flashing fails, technicians turn to the ISP (In-System Programming) Pinout method.

This guide provides the technical details for connecting the SM-M017F motherboard directly to an eMMC adapter for repair and data recovery. ⚡ What is an ISP Pinout?

An ISP pinout allows you to communicate directly with the phone's eMMC storage chip without removing it from the logic board. By soldering small wires to specific test points, you can bypass the operating system to: Repair Dead Boots: Fix devices that won't turn on. Remove FRP: Bypass Google Factory Reset Protection.

Unlock Patterns/PINs: Reset user locks when recovery mode is inaccessible.

Direct Flashing: Write firmware directly to the EMMC partitions. 🛠️ Required Tools

To perform an ISP connection on the Samsung M017F, you will need: ISP Hardware Box: EasyJTAG Plus, Medusa Pro II, or UFI Box.

Soldering Station: A fine-tip iron is mandatory for these microscopic points. Jumper Wire: 0.1mm enameled copper wire. Magnification: A digital microscope or jeweler's loupe. High-Quality Flux: To ensure clean, solid connections. 📍 Samsung SM-M017F ISP Pinout Diagram

The SM-M017F is powered by a MediaTek MT6739 chipset. To establish a connection, you must solder wires to these four primary points on the PCB: Key Connection Points: DAT0: The data line for transferring information. CMD: The command line to initiate instructions. CLK: The clock line to synchronize data flow. GND: Ground (can be soldered to any metal shield). VCC & VCCQ: Power lines (usually 2.8V and 1.8V). Expert Warning: Do not connect VCC (3

💡 Pro Tip: You can often skip soldering VCC and VCCQ by plugging a USB cable into the phone during the process to provide power, though a direct connection is more stable. 📝 Step-by-Step Connection Process

Disassemble the Device: Carefully remove the back cover and the internal screws.

Locate the Points: Use a high-resolution pinout image to find the test points near the eMMC chip.

Prepare the Surface: Apply a tiny amount of flux to the test points.

Solder the Jumpers: Keep your wires as short as possible (under 10cm) to prevent data noise and connection failures.

Connect to Box: Plug the wires into your ISP adapter (UFI, EasyJTAG, etc.).

Identify Device: Open your software and click "Identify" or "Check eMMC." ⚠️ Critical Safety Warnings

Heat Sensitivity: Excessive heat on the tiny resistors near the CLK/CMD lines can knock them off, permanently killing the board.

Short Circuits: Ensure no stray solder bridges touch the surrounding metal shields.

Backup First: Always perform a Dump of the "ROM1, ROM2, and ROM3" partitions before making any changes. This is your "undo" button if things go wrong.
