The Samsung M017F’s eMMC is powered by the main board’s PMIC (Power Management IC). If you inject external power, you will back-feed the PMIC and burn the motherboard.
This method is typically used in forensic data extraction, unlocking, or repairing “dead” devices where the phone is completely unresponsive (hard bricked), as it bypasses the main processor entirely. For the Galaxy M01s (SM-M017F), its storage uses the interface.
For professional results, it is strongly advised to consult the official and Schematic Diagram . Reputable phone repair websites (e.g., schematic-expert.com , mobilerdx.com ) host these documents, offering the verified pinout for advanced repairs. The full schematic includes the layout of all main electrical parts and Level 1-3 repair procedures, where the ISP test points would be detailed. samsung m017f isp pinout

Once the hardware connection is secure, open your preferred eMMC software module on your PC (e.g., UFI Android ToolBox or EasyJtag Plus Emmc Tool Suite). 1. Detecting the Storage The Samsung M017F’s eMMC is powered by the
The Samsung SM-M017F is powered by a MediaTek MT6762 (Helio P22) processor. MediaTek-based devices often have slightly different pinout characteristics compared to Qualcomm-based phones. Sometimes, you might need to short a specific test point on the board to force the eMMC into a boot mode before it becomes detectable by the ISP programmer. This is another reason why having a verified pinout from a reliable source is invaluable, as it saves hours of trial and error.
Carefully desolder or cut away the metal EMI shield covering the MediaTek MT6739WW section to expose the tiny test pads. Step 2: Micro-Soldering the Jumpers For the Galaxy M01s (SM-M017F), its storage uses
Plug a high-quality USB cable into the phone's charging port during the read/write process. Powers the I/O bus lines and controller logic. Solder directly to the VCCQ capacitor test point.
After analyzing the mainboard schematics (PCB Rev. 1.0) and practical reverse engineering, the verified ISP pinout for the Samsung M017F is as follows:
Shuttles device commands and responses back and forth.
