The Samsung Galaxy M01 Core (SM-M017F) uses an eMMC-based In-System Programming (ISP) pinout for tasks such as dead boot repair, FRP (Factory Reset Protection) bypassing, and data recovery when standard software methods (like EDL mode or USB debugging) are unavailable. ISP Pinout Connections
For direct eMMC access using tools like UFI Box, Z3X EasyJTAG Plus, or Medusa Pro, you must solder jumpers to the following points on the motherboard: DAT0: Data line for transmitting data bits.
CMD: Command line for sending instructions to the eMMC chip. CLK: Clock signal to synchronize data transfer.
VCC: Power supply for the eMMC controller (typically 2.8V – 3.3V). VCCQ: Power supply for the I/O signals (typically 1.8V). GND: Ground connection. Key Resources for Diagrams
Because soldering requires precision, it is recommended to use high-definition (HD) visual guides. You can find "extra quality" diagrams at the following locations: samsung m017f isp pinout extra quality
Video Guides: Step-by-step soldering and software procedures are available on YouTube.
Hardware Schematics: Detailed motherboard photos with marked test points are often posted in technical groups like Tara Mobile Service on Facebook.
Technical Databases: Authoritative pinout libraries are maintained by tool manufacturers like the Easy JTAG Knowledge Base. Important Precautions
Heat Shield Removal: ISP points are often located under metal shields near the eMMC chip. Use a hot air station carefully to avoid damaging surrounding components. The Samsung Galaxy M01 Core (SM-M017F) uses an
Microscope Usage: Given the tiny size of these points, using a microscope or high-power magnifier is crucial for accurate soldering.
Voltage Safety: Ensure the correct voltage is applied to VCC and VCCQ to avoid permanently frying the eMMC chip.
Here is the technical guide for the Samsung M017F (likely a typo or variant of the Samsung SM-M017F, often the Galaxy M01 core or similar MTK device) ISP pinout.
Disclaimer: This guide is for professional repair technicians and educational purposes. Modifying your device may void the warranty. Incorrect wiring can damage the motherboard. Double-check with a multimeter before powering on. Connecting to the Programmer – Software Configuration Once
Once physically wired, attach the wires to your programmer’s eMMC ISP port.
| Programmer Side | Connect to M017F | | :--- | :--- | | VCC (3.3V output) | Do NOT connect. Use phone battery. | | VCCQ (1.8V out) | Connect to TP_R614 | | GND | GND (your ground point) | | CMD | CMD | | CLK | CLK | | DAT0 | DAT0 |
Launch your software (e.g., Medusa Pro). Select Manual eMMC -> Samsung -> M017F Profile. Set Voltage I/O to 1.8V. Click "Test". You should see CID, CSD, and EXT_CSD registers appear.
If you see "CMD timeout" or "CRC error", your connection lacks extra quality. Re-inspect CLK and GND.
Remove motherboard, locate eMMC (BGA, usually marked Samsung KLM or similar). Note orientation (dot = pin 1).
