If your Moto G4 (XT2421-4) is based on a Spreadtrum (SPD) chipset and became unresponsive after attempting to remove the FRP lock, you’ll need to follow a specific set of procedures tailored to SPD devices. Here’s how you can try to recover your dead Moto G4:

Article: Recovering a Dead Moto G4 (XT2421-4) After FRP Removal on SPD Chipset

Introduction

Removing the Factory Reset Protection (FRP) on a Moto G4 with an SPD (Spreadtrum) chipset can sometimes result in the device becoming unresponsive or “bricked.” This typically happens due to corruption of the firmware during the FRP removal process. This guide will walk you through the steps to revive your device using SPD-specific tools and methods.

1. Diagnose the Device Condition

First, determine the current state of your device:

• Completely Dead: The phone shows no signs of life (no boot screen, no LED lights).
• Boot Loop or Stuck on Logo: The device powers on but doesn’t progress beyond the boot logo.
• Boots into Recovery or Fastboot Mode: The device is stuck in Recovery or Fastboot mode.

2. Prepare the Required Tools

For SPD devices, you’ll need specific tools to recover the firmware:

• SPD Flash Tool (Spreadtrum Upgrade Tool): This tool is used to flash the firmware on Spreadtrum devices.
• Stock Firmware for Moto G4 (XT2421-4): Download the correct firmware specific to your device model and region. Make sure it’s for the SPD variant of the Moto G4.
• SPD USB Drivers: Ensure these drivers are installed on your computer to allow the SPD Flash Tool to communicate with your device.

3. Flashing the Stock Firmware

If your device is not completely dead, you can proceed to reflash the stock firmware:

Steps to Flash Firmware Using SPD Flash Tool:

1. Install SPD Drivers: Install the SPD USB drivers on your computer to ensure the device is recognized when connected.
2. Prepare the SPD Flash Tool:
   • Download and extract the SPD Flash Tool to your computer.
   • Extract the firmware files specific to your Moto G4.
3. Load the Firmware:
   • Launch the SPD Flash Tool.
   • In the tool, click on the “Load Packet” button and select the firmware package you extracted earlier.
4. Connect Your Device:
   • Power off your Moto G4 completely.
   • Connect your device to the computer using a USB cable while holding the Volume Down button (this may vary by device, so try different combinations if this doesn’t work).
5. Start the Flashing Process:
   • Once the device is detected by the tool, click on the “Start Downloading” button in the SPD Flash Tool.
   • The tool will begin flashing the firmware to your device. Do not disconnect your device during this process.
6. Wait for Completion:
   • The flashing process may take several minutes. Once it’s done, you should see a success message in the tool.
   • Disconnect the device from the computer and try powering it on.

4. Handling a Completely Dead Device

If the device is completely unresponsive, try the following:

• Test Point Method for SPD:
  • Some SPD devices allow you to enter a special download mode by shorting specific test points on the motherboard. This method can force the device into a mode where it can be flashed using the SPD Flash Tool.
  • This method requires opening the device and identifying the correct test points. Proceed with caution as it can be risky and may void your warranty.

5. Post-Flashing Steps

• First Boot: After successfully flashing the firmware, the first boot may take longer than usual. Be patient.
• Set Up Device: Once the device boots up, you’ll need to go through the initial setup process.

Conclusion

Recovering a dead Moto G4 (XT2421-4) after a failed FRP removal attempt on an SPD chipset can be challenging but is often possible with the right tools and steps. If you’re not experienced with flashing firmware or handling hardware-level repairs, it may be best to consult a professional technician. Always ensure that you’re using the correct firmware and tools to avoid further issues
