Samsung M017f Isp Pinout Guide

Question

This report covers the ISP (In-System Programming) pinout for the Samsung Galaxy M01s (SM-M017F), a device primarily used for memory repair, FRP bypass, or pattern unlocking using tools like EasyJtag, UFI Box, or Flash64. 1. Device Identification Model: Samsung Galaxy M01s Technical Name: SM-M017F Chipset: MediaTek Helio P22 (MT6762) Storage Type: eMMC 2. ISP Pinout Connections

To perform ISP operations, you must solder jump wires to specific test points on the motherboard. The standard required connections are: Signal Name CLK Clock Signal Synchronization for data transfer. CMD Command Line For sending instructions to the eMMC. DAT0 Primary data line for basic 1-bit operations. VCC Core Voltage Supplies 2.8V–3.3V to the eMMC core. VCCQ I/O Voltage Supplies 1.8V to the I/O lines. GND Common reference ground for the circuit.

Important Note: For stable connection in some boxes, technicians recommend jumpering the CMD register or using a resistor (0Ω to 47Ω) to prevent auto-disconnection. 3. Operational Use Cases Easy auto boot v2.3.3 workflow and features - Facebook

1. Executive Summary

This report details the ISP (eMMC) pinout locations and procedures for the Samsung SM-M017F (Galaxy M01). The device utilizes the Qualcomm SDM439 chipset. Accessing the ISP pinout is typically required when the device is in a "hard brick" state (Qualcomm HS-USB QDLoader 9008 mode) and standard flashing methods via Odin have failed, or for forensic data extraction where the USB debugging (ADB) is disabled.

Safety checklist before connecting ISP

Confirm correct ground connection.
Ensure target and host share common ground.
Match voltage levels (use 3.3V logic).
Do not inject higher voltages into eMMC or SoC.
If unsure, stop and consult a schematic or professional repair service.

Step 5: Read / Write

Backup: Always read the Full Flash (User area + Boot1 + Boot2) first. Save the .bin file.
Write: Load the extracted preloader_m017f.bin, lk.bin, and boot.img from the stock firmware.
Click "Write" and wait 15-20 minutes.
For FRP Reset: Only write the nvdata and persistent partitions.

Common Problems & Troubleshooting

Wiring Diagram for ISP Boxes (Easy Jtag / Medusa / UFI)

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.

Step 4: Identification

Click "Detect" or "Identify eMMC".
A successful detection will show:
- eMMC Name: Samsung 4G (or 3G)
- CID: 150100...
- Boot1/Boot2 size
If you see No eMMC found or CMD timeout, recheck your CLK and CMD solder joints.

Step 3: Power Sequencing

Connect the ISP box to your PC via USB.
Do not power the motherboard yet.
In the ISP software, select "Samsung" -> "M017F" (or "MT6762 Generic").
Enable "External Power" or "Target Power" depending on your box.
Now connect the battery or DC supply to the motherboard.
