Samsung M35 5G M356B ISP Pinout Solution

The Samsung M35 5G M356B ISP Pinout solution provides a precise method for accessing and repairing the device’s eMMC or UFS chip without removing it from the motherboard

This is crucial when dealing with issues like dead boot, FRP lock, or data recovery. By carefully identifying the correct ISP points near the UFS chip under the metal shield, technicians can connect directly to the device using tools like UFI Box, Easy JTAG, or Medusa Pro.

Post Index:The key pins to focus on include CLK, TXOP, TXON, RXOP, RXON, and GND. Once connected, the proper software tools can be used to perform various operations such as firmware flashing, partition repairs, or FRP reset. Always ensure that the device's battery is removed, the PCB is cleaned, and all connections are double-checked with a multimeter to avoid shorts. This method enables repair even when the device is unresponsive, ensuring a high success rate for restoration tasks.

Samsung M35 5G M356B ISP In this guide, we'll cover the ISP pinout for the Samsung Galaxy M35 5G (model M356B) mainboard, which is essential for entering EDL mode or performing various tasks such as dead boot repairs, FRP unlock, firmware flashing, and data recovery using tools like Easy JTAG, UFI, or Hydra. I'll walk you through the complete process, including the necessary tools, helpful connection tips, and common troubleshooting steps, all based on practical experience.

What is ISP (In-System Programming)?

Samsung M35 5G M356B ISP Simply put, ISP lets you access the eMMC chip without needing to remove it from the device. All you have to do is identify the correct pinout on the board and use a compatible tool like UFI, Easy JTAG, or Medusa Pro to connect directly to it.

ISP pinout is especially useful in the following situations:

When the phone is dead (black screen, no boot, no charging)

If the FRP is locked and you can't use ADB, fastboot, or OTG bypass

When you need to dump firmware from a working device to repair a dead one

If you're working on a boot repair or partition restoration

When the phone is detected as "unknown" on the PC and EDL mode isn't working

This is where things get a bit technical. The Samsung M35 5G M356B shares a similar hardware layout with other models, but the exact pin locations can vary slightly. You’ll typically find the ISP points near the UFS chip, which is located under the metal shield.

Key UFS ISP Pin Labels You’ll Need:

CLK

TXOP

TXON

RXOP

RXON

GND (Ground)

💡 Tip: Use a microscope or a 10x magnifier to ensure you identify the points accurately. Don't rely solely on diagrams—it's crucial to confirm the layout visually.

Samsung M35 5G M356B ISP When dealing with dead boot issues, particularly on devices like the Samsung M35 5G M356B, tools like Easy JTAG Plus and UFI Box dongles are invaluable for mobile repair. These tools are especially helpful when the phone has been improperly flashed, fails to show the startup logo, and no longer responds to power.

Required Tools for ISP Pinout:

Before you begin, ensure your workbench is equipped with the right tools:

UFI Box, Easy JTAG, or Medusa Pro

0.1mm – 0.3mm jumper wires

Fine-tip soldering iron

Isopropyl alcohol (IPA 99%) for cleaning

Soldering flux

Multimeter (to check continuity)

How to Connect ISP to eMMC Tool:

Remove the battery from the phone. This is crucial to avoid any voltage conflicts.

Clean the PCB area with isopropyl alcohol to ensure good contact points.

Carefully solder jumper wires to the following pins: CLK, TXON, TXOP, GND, RXON, and RXOP.

Connect the jumper wires to your UFS or eMMC tool, following the pinout for your specific device.

Double-check each wire with a multimeter to make sure there are no shorts. Once you're confident in your connections, plug into your UFI or Easy JTAG tool.

In the UFI or Easy JTAG Software:

Select Identify UFS eMMC from the menu.
