Connect CLK, CMD, D0, and GND to your ISP box’s eMMC interface (e.g., Easy JTAG’s 4-bit SDIO port). Configure your software for 1-bit mode (D0 only) – SM-M017F may not support 4-bit ISP reliably.
For technicians using the UFI Box (popular in Asian markets), the pin mapping is identical:
Run UFI’s “eMMC ISP” autodetect. If detection fails, manually set eMMC 5.1, 1-bit, 1.8V I/O. samsung m017f isp pinout
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. Connect CLK, CMD, D0, and GND to your
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. Run UFI’s “eMMC ISP” autodetect
| 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 component side of the PCB, near the eMMC, you will see three tiny gold pads arranged in a row:
Nearby, there is a large unpopulated pad or a ground shield – use that for GND.
