Modified cable for EUB MODE
Modified cable for EUB MODE is ued for samsung devices that have exynos cpu.
EUB(Exynos usb boot) Mode cable:
Connect a 301 kΩ resistor between Pin 4 (ID) and Pin 5 (GND) of a USB-C connector to potentially trigger EUB Mode on a connected device.
Here’s a more detailed breakdown of the process, emphasizing the technical aspects and potential risks:
What you need to fix the EUB mode cable:
* USB-C Connector or Cable: You’ll need a USB-C connector that you can modify or a cable that you can carefully expose the internal wires of.
* 301 kΩ Resistor: A resistor with a precise value of 301 kilo-ohms. You might need to check the color code on the resistor to confirm its value (typically Orange-Black-Brown-Red-Brown for a 1% tolerance resistor).
* Fine-tipped Soldering Iron: For making reliable electrical connections.
* Solder: Electronic-grade solder.
* Flux (Optional but Recommended): Helps the solder flow and create a better connection.
* Multimeter (Recommended): To verify the resistor value and check for shorts after soldering.
* Magnifying Glass or Microscope (Helpful): Due to the small size of USB-C pins.
* Precision Wire Strippers (If modifying a cable): To carefully expose the internal wires without damaging them.
* Helping Hands or a Vice: To hold the connector steady during soldering.
* Safety Glasses: To protect your eyes.
Step-by-Step Procedure:
* Identify Pin 4 (ID) and Pin 5 (GND) on the USB-C Connector: This is the most crucial step. You’ll need a reliable pinout diagram for the specific USB-C connector you are working with. The image provides a visual indication, but variations exist. Search online for the pinout of the specific USB-C connector you have.
* Prepare the Resistor: Ensure the resistor leads are clean and appropriately trimmed for soldering.
* Tin the Wires/Pads (Optional but Recommended): Apply a small amount of solder to the pads on the USB-C connector corresponding to Pin 4 and Pin 5, as well as the leads of the resistor. This “tinning” makes the final soldering process easier and results in a better connection.
* Position the Resistor: Carefully position the resistor so that one lead is in contact with the pad for Pin 4 (ID) and the other lead is in contact with the pad for Pin 5 (GND).
* Solder the Connections: Using a fine-tipped soldering iron, carefully solder each lead of the resistor to the corresponding pin on the USB-C connector. Apply heat to the pad and the resistor lead, then feed in a small amount of solder. Ensure a clean and shiny solder joint. Avoid creating solder bridges (unintended connections) between adjacent pins.
* Inspect the Connections: Use a magnifying glass or microscope to carefully inspect the solder joints. Ensure they are solid and there are no shorts between pins.
* Verify with a Multimeter (Recommended):
* Resistance Check: Set your multimeter to measure resistance and check the resistance between Pin 4 and Pin 5 of the modified connector. It should read approximately 301 kΩ.
* Continuity Check: Check for continuity between Pin 5 and any other ground pins on the USB-C connector to ensure the intended ground connection. Also, check for any unintended continuity (shorts) between Pin 4 and adjacent pins.
* Isolate and Protect (If modifying a cable): If you modified a USB-C cable, carefully insulate the soldered connections to prevent shorts. You can use electrical tape or heat-shrink tubing.
Critical Warnings and Precautions:
* Risk of Damage: Incorrect soldering or using the wrong resistor can permanently damage your device. Proceed at your own risk.
* Device Compatibility: This EUB mode configuration might be specific to certain devices (potentially Asus, based on previous context). It may not work and could be harmful to other devices.
* Expertise Required: This is an advanced procedure that requires soldering skills and a good understanding of electronics. If you are not comfortable with soldering and electronic components, do not attempt this yourself. Seek help from someone experienced in micro-soldering.
* Static Discharge: Be mindful of electrostatic discharge (ESD) during the process, as it can damage sensitive electronic components. Use an anti-static mat and wrist strap if possible.
In summary, performing this action involves precise soldering of a specific resistor between two designated pins on a USB-C connector. It’s a delicate and potentially risky operation that should only be undertaken by experienced individuals with the necessary skills and equipment.
