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.
| ISP Pin Name | Signal | Function | Test Point Location (Typical) | Color Code (JIG) | |--------------|--------|----------|-------------------------------|------------------| | 1 | VCC | eMMC Power (3.3V) | TP_VCC_EMMC | Red | | 2 | GND | Ground | Any large copper area / TP_GND | Black | | 3 | CMD | Command line | TP_CMD | Orange | | 4 | CLK | Clock (up to 50 MHz) | TP_CLK | Yellow | | 5 | DAT0 | Data line 0 (main data) | TP_DAT0 | Green | | 6 | DAT1 | Optional data line | TP_DAT1 | Blue (optional) | | 7 | DAT2 | Optional data line | TP_DAT2 | Purple (optional) | | 8 | DAT3 | Optional data line | TP_DAT3 | Gray (optional) |
Note: Minimal ISP connection requires VCC, GND, CMD, CLK, DAT0 (5 wires). DAT1-3 are used for 4-bit mode to increase speed.
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. samsung m017f isp pinout
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.
| Issue | Likely Cause | Solution | |-------|--------------|----------| | No response from eMMC | VCC not stable or missing | Solder directly to eMMC capacitor | | CRC errors on DAT0 | Poor ground connection | Use separate thick GND wire | | CLK stuck low | Short to GND on PCB | Check test point for solder bridge | | Device detected as 0 bytes | eMMC dead or in boot ROM mode | Replace eMMC or check reset pin | This report details the ISP (eMMC) pinout locations
The Samsung M017F ISP pinout (CLK, CMD, D0, GND at the designated test points) is a lifeline for technicians facing dead boot or locked devices. By powering the board externally via battery terminals and supplying a clean 1.8V I/O from your programmer, you can revive any software-killed M017F in under 20 minutes.
Final checklist:
Mastering this ISP pinout transforms your repair capability from “another dead Samsung” to a guaranteed fix. Bookmark this guide and share it within repair communities – the M017F will remain in circulation for years, and ISP remains the ultimate bypass. Note: Minimal ISP connection requires VCC, GND, CMD,
