  • Charging port feels loose or is physically damaged.
  • Charging icon appears but the device does not gain charge.

Tools and Materials Needed
  1. Multimeter (to test continuity and voltage)
  2. Fine-tipped soldering iron and solder
  3. Thin jumper wires
  4. Precision screwdriver set
  5. Tweezers
  6. Isopropyl alcohol and microfiber cloth
  7. Magnifying glass or microscope (optional)

Causes of the USB Charging Problem
  1. Physical Damage: Broken USB port or pins inside the port.
  2. Corroded Connections: Dirt or corrosion on the motherboard or USB port.
  3. Damaged PCB Traces: Broken or disconnected tracks leading to the charging circuit.
  4. Faulty Components: Burnt resistors, capacitors, or diodes near the charging IC.

Steps to Perform the Jumper Solution

Step 1: Disassemble the Phone
  1. Turn off the phone and remove the back cover, battery, SIM card, and microSD card.
  2. Unscrew and gently pry open the back panel using a plastic prying tool.
  3. Disconnect all flex cables and remove the motherboard from the phone casing.
Step 2: Inspect the Charging Port and Circuit
  1. Visually inspect the USB port for physical damage, such as bent or broken pins.
  2. Check the motherboard for burn marks or corroded solder points around the USB port.
Step 3: Test Continuity with a Multimeter
  • Set your multimeter to continuity mode and test the following:
    • The VBUS pin (charging line) of the USB port to the motherboard track.
    • The GND pin (ground) of the USB port to any ground point on the motherboard.
  • If continuity fails, you’ll need to create jumper wires to restore the connection.
Step 4: Identify Jumper Points
  1. VBUS (5V): Locate an alternative connection point for the 5V input from the USB port. This is often a nearby capacitor or fuse.
  2. GND (Ground): Any metallic ground point on the motherboard can be used.
  3. Data Lines (Optional): For USB data transfer issues, identify the D+ and D- tracks leading from the USB port.
Step 5: Clean the Damaged Area
  • Use isopropyl alcohol and a microfiber cloth to clean the damaged tracks or solder points on the motherboard.
Step 6: Perform the Jumper Repair
  1. Use a fine-tipped soldering iron to solder one end of a jumper wire to the USB port pin (VBUS or GND).
  2. Connect the other end of the wire to an alternative point on the motherboard: 
    • For VBUS (5V): Connect to a nearby capacitor or directly to the charging IC input pin.
    • For GND: Connect to any ground pad or metallic shield on the motherboard.
  1. If the data lines (D+ and D-) are damaged, solder jumper wires to their respective alternate points.
Step 7: Secure the Jumper Wires
  • Apply a small amount of adhesive or tape to hold the wires in place and prevent them from shorting other components.
Step 8: Reassemble and Test
  1. Reassemble the phone by reconnecting all flex cables, replacing the screws, and reinserting the battery.
  2. Connect the device to a charger and verify that it charges normally.
  3. Test data transfer by connecting the phone to a computer via USB.

Common Jumper Points for Samsung Galaxy J7 J701F

  • VBUS (5V): Connect the charging IC to a nearby capacitor or power rail.
  • GND: Make use of any metal ground point that is exposed.
  • D+ and D-: Look for alternate solder locations by following the tracks from the USB port to the motherboard.

Precautions

  1. Use the Right Tools: To prevent harming adjacent components, use tools with fine tips.
  2. Prevent Overheating: The motherboard may sustain harm from excessive heat.
  3. Verify Connections Again: Make sure the solder points don't short circuit.
  4. Seek Professional Assistance: Speak with a specialist if you lack soldering or PCB repair skills.

Using a jumper solution to fix the Samsung Galaxy J7 J701F's USB charging issue is an affordable way to get functionality back. You can prevent the need for a complete USB port replacement by locating the faulty connections and carefully avoiding them with jumper wires. But for a repair to be successful, accuracy and patience are essential.

Samsung J7 J701F Charging USB Troubleshooting Guide

Connect the USB cable to the computer and the phone jack, and read the notifications on the phone screen that is recognized or not. Check that you can save the data to the memory card or not. Replace the USB data cable and try again.

Before proceeding with solutions, it's essential to recognize the signs of charging issues on the Samsung Galaxy J7 J701F:

  1. Slow Charging: The device charges at a significantly slower rate than usual, taking longer to reach full battery capacity.
  2. Intermittent Charging: Charging is inconsistent, with the device charging and then stopping abruptly or charging intermittently.
  3. No Charging Response: The device does not respond at all when connected to a charger via USB, indicating a complete failure to charge.

Possible Causes

Several factors can contribute to charging problems on the Samsung Galaxy J7 J701F:

  1. Faulty Charging Cable or Adapter: A damaged or defective USB cable or charging adapter can impede proper charging.
  2. Dirt or Debris in Charging Port: Accumulated dirt, lint, or debris in the charging port can prevent a secure connection between the cable and the device.
  3. Software Issues: Software glitches or bugs in the device's operating system can affect charging functionality.
Here are some troubleshooting steps to address charging issues with the Samsung Galaxy J7 J701F:

  1. Inspect the Charging Cable and Adapter:Check the USB cable and charging adapter for any signs of damage, such as frayed wires or bent connectors. Replace them if necessary.
  2. Clean the Charging Port:Power off the device and use a small, clean brush or compressed air to remove any dirt, lint, or debris from the charging port. Be gentle to avoid causing damage.
  3. Try a Different Charging Cable and Adapter:If possible, use another USB cable and charging adapter to test if the issue lies with the original accessories. Ensure that the replacement components are compatible with the device.
  4. Restart the Device:Perform a soft reset by restarting the device. This can help resolve temporary software glitches affecting charging.
  5. Enable Fast Charging (if available):If your device supports fast charging, ensure that it is enabled in the device settings. Go to Settings > Device Maintenance > Battery > More options > Advanced settings, then enable Fast cable charging.
  6. Check for Software Updates:Ensure that your device's software is up to date by checking for and installing any available updates. Software updates often include bug fixes and optimizations that can improve charging performance.
  7. Perform a Factory Reset:If all else fails, consider performing a factory reset on your device to reset all settings to their default values. Backup your important data first, as this process will erase all data on the device.
