Troubleshooting NetHunter Installation on Rubyfish: A Comprehensive Guide

Encountering issues while installing Kali NetHunter can be frustrating. This guide provides a detailed walkthrough to address the “Booting FAILED (remote: ‘unknown reason’)” error, specifically focusing on the Rubyfish device, and leverages the information available from the Kali NetHunter documentation and community resources. We aim to provide a comprehensive solution encompassing various potential causes and troubleshooting steps.

Understanding the “Booting FAILED (remote: ‘unknown reason’)” Error

This error, commonly encountered during fastboot operations, indicates a failure during the boot image flashing process. The “unknown reason” component signifies that the bootloader couldn’t identify the specific cause of the failure, making diagnosis more challenging. Several factors can contribute to this issue, ranging from incorrect image files to bootloader limitations.

Pre-Installation Checklist: Verifying Essential Requirements

Before diving into troubleshooting, ensure the following prerequisites are met:

  • Correct NetHunter Image: Confirm you’ve downloaded the correct NetHunter image specifically designed for the Rubyfish device from the official Kali NetHunter downloads page. Double-check the filename and MD5 checksum against the provided values to guarantee image integrity. The link provided by the user points to a specific directory: https://kali.download/nethunter-images/devices/rubyfish/. Always download the latest stable version.

  • ADB and Fastboot Installation: Ensure that Android Debug Bridge (ADB) and Fastboot are correctly installed and configured on your computer. Verify that the paths to these tools are added to your system’s environment variables for easy access from the command line. You can typically obtain these tools through the Android SDK Platform Tools package.

  • USB Debugging Enabled: On your Rubyfish device, enable USB debugging within the Developer Options. To unlock Developer Options, navigate to “Settings” -> “About phone” and tap the “Build number” seven times. After enabling Developer Options, find and enable USB debugging.

  • OEM Unlocking Enabled: Crucially, ensure that OEM unlocking is enabled in the Developer Options. This setting allows for modifications to the bootloader, which is necessary for installing custom ROMs and recoveries like NetHunter. This is often the root cause of “remote: unknown reason” errors.

  • Sufficient Battery: Maintain a battery level of at least 50% on your Rubyfish device to prevent interruptions during the flashing process. A sudden power loss can lead to a bricked device.

  • Correct USB Cable: Use a high-quality USB cable to establish a stable connection between your computer and your Rubyfish device. Faulty cables can cause data transfer errors, leading to flashing failures.

Step-by-Step Troubleshooting Guide

1. Verifying Fastboot Connectivity

Before proceeding with flashing, confirm that your computer can properly communicate with your Rubyfish device in Fastboot mode.

  1. Connect your device to your computer via USB.
  2. Open a terminal or command prompt.
  3. Execute the command fastboot devices.

If your device is recognized, you should see its serial number listed. If not, troubleshoot USB drivers, ensuring the correct Android ADB and Fastboot drivers are installed. Try different USB ports. Sometimes a USB 2.0 port works better than a USB 3.0 port for fastboot.

2. Addressing Potential Driver Issues

Incorrect or outdated USB drivers are a common cause of Fastboot communication problems.

  1. Reinstalling ADB and Fastboot Drivers: Completely uninstall the existing ADB and Fastboot drivers from your computer. Then, download the latest drivers from the Android SDK Platform Tools or a reliable third-party source.
  2. Using Google USB Driver: For Windows users, the Google USB Driver is often the most compatible option. Download it from the Android developer website and install it through the Device Manager. Manually point the driver installation to the extracted Google USB Driver folder.
  3. Driver Signature Enforcement (Windows): On Windows, driver signature enforcement can sometimes interfere with Fastboot. Temporarily disable driver signature enforcement to see if it resolves the issue. To do this, restart your computer and enter the Advanced Boot Options menu (usually by pressing F8 repeatedly during startup). Select “Disable Driver Signature Enforcement.”

3. Examining Bootloader Unlock Status

A locked bootloader prevents flashing custom images. While you mentioned enabling OEM unlocking, it’s worthwhile to double-check and ensure the bootloader is actually unlocked.

  1. Fastboot Command to Check Unlock Status: Use the command fastboot oem device-info. This command displays information about your device, including its unlock status. Look for a line that indicates whether the device is unlocked.
  2. Unlocking the Bootloader (If Necessary): Warning: Unlocking the bootloader will erase all data on your device. If the device is locked, you’ll need to unlock it. The process varies depending on the manufacturer. Generally, it involves using a command like fastboot oem unlock. Follow the specific instructions for your Rubyfish device. The TicWatch Pro 3, for instance, requires specific commands found on forums dedicated to the device.
  3. Bootloader Unlock Confirmation: After attempting to unlock, carefully observe the device screen for a confirmation prompt. You may need to use the volume and power buttons to confirm the unlock.

4. Verifying Image Integrity and Flashing Procedure

Even with the correct image and proper drivers, errors can occur during the flashing process if the image is corrupted or the flashing commands are incorrect.

  1. MD5 Checksum Verification: As mentioned earlier, verify the MD5 checksum of the downloaded NetHunter image against the value provided on the Kali NetHunter downloads page. This ensures that the downloaded file is complete and uncorrupted. Tools like md5sum (Linux/macOS) or similar utilities on Windows can be used to calculate the MD5 checksum.

  2. Correct Fastboot Command: Use the correct Fastboot command to flash the boot image. The command you provided, fastboot boot rubyfish_recovery.img, attempts to boot the image rather than flash it. To permanently flash the image, use the following command:

    fastboot flash boot rubyfish_recovery.img

    This command specifically targets the “boot” partition for flashing.

  3. Alternative Flashing Method: Using fastboot flash recovery: Some devices require flashing the recovery image to the recovery partition instead of the boot partition. Try using the following command:

    fastboot flash recovery rubyfish_recovery.img

    After flashing the recovery image, you can then boot into the custom recovery to flash the NetHunter image.

  4. File Naming and Path: Ensure that the rubyfish_recovery.img file is in the same directory as your Fastboot executable, or provide the full path to the image file in the Fastboot command.

  5. Retry the Flash: Sometimes, a simple retry can resolve intermittent issues. Close and reopen the command prompt, reconnect the device, and re-execute the Fastboot command.

5. Addressing Bootloader Compatibility and Versioning

In some cases, the bootloader version on your device might be incompatible with the NetHunter image you’re trying to flash. This is more common when dealing with older devices or custom ROMs.

  1. Research Bootloader Compatibility: Investigate whether there are known compatibility issues between the bootloader version on your Rubyfish device and the NetHunter image. Consult online forums, device-specific communities, and the Kali NetHunter documentation for information on compatible bootloader versions.
  2. Updating the Bootloader (Advanced): Warning: This is an advanced procedure and carries a significant risk of bricking your device. Proceed with caution and only if you are comfortable with the risks involved. If a bootloader incompatibility is identified, you might need to update or downgrade the bootloader. This typically involves flashing a specific bootloader image using Fastboot. This process is device-specific and requires careful research and adherence to instructions.
  3. Flashing a Different NetHunter Version: Attempt to flash an older version of NetHunter. Sometimes, newer versions introduce compatibility issues with older devices.

6. Considering Custom Recoveries (TWRP)

While NetHunter often provides its own recovery image, using a custom recovery like TWRP (Team Win Recovery Project) can sometimes facilitate the installation process.

  1. Flashing TWRP (If Available): Check if a TWRP recovery image is available for your Rubyfish device. If so, flash it using Fastboot:

    fastboot flash recovery twrp_rubyfish.img

    Replace twrp_rubyfish.img with the actual filename of the TWRP image.

  2. Booting into TWRP: After flashing TWRP, boot into recovery mode. The key combination to enter recovery mode varies depending on the device manufacturer. Typically, it involves pressing a combination of power, volume up, and/or volume down buttons during startup.

  3. Flashing NetHunter from TWRP: Once in TWRP, you can try flashing the NetHunter image directly from the recovery environment. Copy the NetHunter image to your device’s internal storage or an external SD card. Then, in TWRP, select “Install” and browse to the NetHunter image file.
