Note: If you use the USB cable method to power the board, you do not need to solder the physical VCC and VCCQ jumper wires from your hardware box. Step-by-Step Connection Procedure Step 1: Board Preparation Completely power down the device. Disconnect the battery flex cable from the logic board. Remove the motherboard from the plastic chassis.
: A common reference point, often connected to the large copper shields on the board. Note : On the
The is a MediaTek-powered budget smartphone that occasionally requires advanced hardware-level servicing to recover from critical software failures. When a device suffers a deep brick, boot loop, or locked FRP (Factory Reset Protection) that standard USB flashing cannot resolve, utilizing the In-System Programming (ISP) Pinout is the ultimate repair path.
| Error Message | Solution | | :--- | :--- | | | Your wires are too long (>15cm). Shorten them to under 10cm and use shielded wires. | | CMD Timeout (0x20) | The eMMC is in sleep mode. You need to reset the device: disconnect battery for 30 seconds, reconnect, and try again. | | Detects eMMC but fails to read | The DAT0 line is unstable. Re-solder DAT0 and ensure your ISP box supports 1-bit mode (the M017F sometimes has a faulty DAT3 line). Force the software to use 1-bit mode. | | Overcurrent (OCP) | You mistakenly connected VCC from the ISP box while the battery was connected. Disconnect immediately. |
If using soldered power lines, configure the software target voltages manually: set and VCCQ to 1.8V . If using a USB cable for power, set the software voltage sliders to neutral. samsung m017f isp pinout
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.
motherboard, these pads are extremely small. Successful soldering requires a high-quality microscope and a fine-tip soldering iron. Step-by-Step Procedure for ISP Connection
Jumper wire with a thickness between 0.02mm and 0.05mm.
Rapid factory reset, user data retrieval, and easy FRP bypass execution. Note: If you use the USB cable method
The command signal that tells the chip what operation to perform. The clock signal that synchronizes data transfer. VCC / VCCQ
: Accessing the 32GB internal storage when the screen is broken or the system is corrupted.
Configure the target bus width to mode (as ISP lines explicitly tap into only the DAT0 data path).

In the sprawling, rain-slicked megacity of Neo-Seoul, data was the new god, and hardware was its temple. Jae was a high priest of this faith, a "Ghost in the Wire," specializing in a dying art: ISP, or In-System Programming. While others chased cloud spirits, Jae chased physical ghosts—the direct, unfiltered whispers from a chip’s core.
Open your chosen software interface (e.g., UFI eMMC ToolBox or EasyJtag Tool). Set the bus width to (required for ISP mode). Set the clock speed to a stable low frequency, such as 24 MHz or 12 MHz . Click Direct Image / eMMC Detect to read the partition table. Important Safety Warning
To utilize the M017F ISP pinout, specialized hardware is required, such as the EasyJTAG Plus
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.
While ISP can be used to recover data, incorrect operations can corrupt the storage and result in permanent data loss. Proceed at your own risk. 📍 Samsung SM-M017F (M01s) ISP Pinout Requirements
Power the phone via its battery connector (3.7-4.2V) OR connect a stable 3.7V supply to the battery B+ contact. The internal PMIC will generate the proper 3.3V for the eMMC.
