Comprehensive Guide to Samsung Galaxy M01s (SM-M017F) ISP Pinouts The Samsung Galaxy M01s (SM-M017F) , often internally codenamed Samsung A107
, is a budget-friendly device powered by the MediaTek Helio P22 (MT6762) chipset. For advanced technicians, the ISP (In-System Programming) pinout is a critical tool for performing deep-level repairs that standard USB-based methods like Odin cannot handle. What is the Samsung M017F ISP Pinout?
ISP pinouts are specific electrical contact points on the motherboard that allow direct communication with the device's eMMC 5.1 storage chip. By "shorting" or connecting to these pins, technicians can bypass the operating system and bootloader to interact directly with the raw memory. This method is primarily used for:
Dead Boot Repair: Reviving phones that show no signs of life and cannot enter Download Mode.
FRP Bypass: Removing Google Factory Reset Protection when software-based bypasses fail.
User Data Recovery: Accessing the 32GB internal storage when the screen is broken or the system is corrupted.
Firmware Restoration: Flashing stock ROMs directly to the eMMC using tools like UFi Box, EasyJtag Plus, or Medusa Pro. Technical Specifications & Hardware
Understanding the hardware is essential before attempting any physical hardware modifications. Specification Model Number SM-M017F/DS Common Name Galaxy M01s (2020) Chipset MediaTek Helio P22 MT6762 Storage Type eMMC 5.1 (32GB) RAM 3GB LPDDR4x Battery Core ISP Pinout Connections To establish a stable connection with the
eMMC, you must identify and solder wires to these six essential points: VCC (2.7v - 3.6v): Main power supply for the eMMC. VCCQ (1.8v or 3.3v): Power for the I/O signals.
CLK (Clock): Synchronizes data transfer between the programmer and the chip. CMD (Command): Sends instructions to the eMMC.
DAT0 (Data 0): The primary data line for reading and writing.
GND (Ground): A common reference point, often connected to the large copper shields on the board. Note: On the
motherboard, these pads are extremely small. Successful soldering requires a high-quality microscope and a fine-tip soldering iron. Step-by-Step Procedure for ISP Connection
Using a tool like the MIPITESTER EASY-JTAG or similar, follow these steps: samsung m017f isp pinout
Disassemble the Device: Remove the back panel and the motherboard from the frame. Locate the eMMC
: The eMMC chip is typically a black square located near the CPU. On the , look for the area near the Helio P22 chip.
Identify Pads: Use a schematic or high-resolution test point image to find the exact pads.
Soldering: 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.
Connect to Box: Plug the wires into your ISP adapter (UFi, EasyJtag, etc.).
Software Detection: Open your chosen software, select the "MediaTek" or "Direct eMMC" brand, and click "Identify." Safety Warnings
Voltage Sensitivity: Applying the wrong voltage to VCCQ (e.g., 3.3v instead of 1.8v) can permanently fry the storage chip.
Battery Disconnection: Always disconnect the battery before probing or soldering to prevent short circuits.
ESD Protection: Use an anti-static mat and wrist strap to avoid damaging sensitive components with static electricity.

An ISP (In-System Programming) pinout for the Samsung Galaxy M01s (SM-M017F)
is a technical map used by mobile technicians to connect directly to the device's eMMC storage chip. This method is typically used to repair "dead" devices that won't turn on, remove forgotten locks, or recover data when the phone’s software is completely unresponsive. Technical Overview of SM-M017F (Galaxy M01s) Chipset: MediaTek Helio P22 (MT6762). Storage Type: eMMC 5.1.
Primary Use for ISP: Dead boot repair, FRP (Factory Reset Protection) removal, and partition flashing using tools like EasyJtag Plus or UFI Box. The Core ISP Pinout Signals Comprehensive Guide to Samsung Galaxy M01s (SM-M017F) ISP
To perform an ISP connection, you must solder tiny wires to specific test points on the motherboard that correspond to the following signals: Description DAT0 The primary data line for communication with the eMMC. CMD
The command signal that tells the chip what operation to perform. CLK The clock signal that synchronizes data transfer. VCC / VCCQ
Power supply pins (usually 2.8V and 1.8V). Technicians often use a USB cable for power instead of soldering these to avoid damage. GND Ground connection to complete the circuit. Important Precautions
Soldering Risk: The test points are extremely small. Using too much heat or the wrong equipment can permanently destroy the motherboard.
Clock Resistance: If the device does not boot after repair, a common fix is to check the CLK resistor, which can sometimes be damaged or disconnected during the soldering process.
Reference Diagrams: Always use high-quality visual guides from reputable sources like the Easy-Jtag Gallery or GSM-specific forums to confirm the exact location of the pins for the .
Are you planning to use a specific repair box like UFI or EasyJtag for this task?
Samsung M017F , commercially known as the Samsung Galaxy M01s
, utilizes an ISP (In-System Programming) pinout to allow technicians to communicate directly with the device's eMMC storage without removing the chip from the motherboard. This advanced repair method is primarily used for recovering "bricked" devices, performing "dead boot" repairs, or bypassing advanced security locks like FRP (Factory Reset Protection) when standard software methods fail. Understanding the ISP Pinout
The ISP pinout for the M017F involves soldering tiny "jumper" wires to specific test points on the PCB (Printed Circuit Board). These points bypass the standard USB interface to provide direct access to the memory controller. Standard connections for this model typically include: : Data line for transmitting information. : Command line for sending instructions to the storage. : Clock line to synchronize data transfer. VCC & VCCQ : Power supply lines (often 1.8V and 2.8V/3.3V). : Ground connection. Practical Applications in Mobile Repair FRP Bypass
: When a device is locked out after a factory reset and the Google account is unknown, technicians use tools like EasyJTAG Plus
or UFI Box to reset the FRP partition via these hardware points. Dead Boot Repair
: If a firmware update fails and the phone no longer turns on or enters Download Mode, the ISP pinout allows a technician to rewrite the "bootloader" files directly to the eMMC. Data Recovery Warnings:
: In cases of physical damage where the screen or charging port is non-functional, ISP provides a way to extract user data from the storage chip. Tools and Precautions
To utilize the M017F ISP pinout, specialized hardware is required, such as the EasyJTAG Plus
, Medusa Pro, or UFI Box. Because the soldering points on the M01s motherboard are extremely small—often located near the Helio P22 processor or under shielding—this procedure carries a high risk of permanent hardware damage if not performed with a microscope and precision soldering equipment.

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:
| Error Message | Solution | | :--- | :--- | | EMI Error / ESD Protection | Your wires are too long (>15cm). Shorten them to under 10cm and use shielded wires. | | CMD Timeout (0x20) | The eMMC is in sleep mode. You need to reset the device: disconnect battery for 30 seconds, reconnect, and try again. | | Detects eMMC but fails to read | The DAT0 line is unstable. Re-solder DAT0 and ensure your ISP box supports 1-bit mode (the M017F sometimes has a faulty DAT3 line). Force the software to use 1-bit mode. | | Overcurrent (OCP) | You mistakenly connected VCC from the ISP box while the battery was connected. Disconnect immediately. |
Before diving into the pinout diagram, it is crucial to understand why ISP is necessary.
The Samsung M017F typically features a MediaTek Helio P22 (MT6762) or similar MTK chipset. When the device suffers from:
In these scenarios, standard USB flashing tools (Odin, SP Flash Tool, or Miracle Box) will return errors like STATUS_BROM_CMD_FAIL or S_BROM_CMD_START_CMD_FAIL. The only recourse is direct memory access via the eMMC's CLK (Clock), CMD (Command), and DAT0 (Data) lines. This is ISP.
