Preserve custom Servers after IX4-300d Update

Lenovo recently released a firmware update for their IX4-300d NAS to address critical security vulnerabilities that left many devices exposed to potential hacker attacks. While it’s highly recommended to apply this update to keep your system secure, users who rely on custom configurations—particularly those using custom startup scripts to run servers or applications—should proceed with caution. Updating the firmware can overwrite or disable these scripts, potentially breaking your setup and preventing essential services from starting automatically.

In this guide, I’ll walk you through the process of safely updating your NAS firmware while preserving your custom server functionality. We’ll back up key configuration files, reapply custom startup scripts post-update, and verify that everything runs smoothly. With the right steps, you can enjoy the latest security improvements without sacrificing the features and tweaks you’ve added to your system.

Requirements

Before you begin, ensure you have the following tools and files ready:

• Latest Lenovo IX4-300d firmware: Download it directly from the official Lenovo support page:
  https://download.lenovo.com/lenovoemc/na/en/app/answers/detail/a_id/32096.html

• SSH Access Tool:

  • Windows users: Use PuTTY

  • Mac/Linux users: Use your system’s built-in Terminal

This method has been successfully tested with all firmware versions up to 4.1.110.33149.

 

 

Updating Firmware – Version 4.1.102.29716 and Up

Access NAS Interface

• Open a web browser and log into your NAS.

• Navigate to “All Features”, then click on the “Software Updates” icon.

• A table will show your current firmware version and offer the option to download the latest version.

Upload and Apply the Firmware

• Click the Action icon and select the downloaded firmware file if it’s not already loaded.

• Click Upload to send the file to your NAS. Once completed, you’ll return to the update screen.

• You should now see a message like:
  “Version 4.1.xxxxx is ready to apply.”
  Click Apply to begin the update process.

Wait 9 to 10 minutes for the update to complete. The NAS will reboot during this process.

Re-enable or Confirm SSH Access
After the firmware update, your NAS should retain SSH access. If SSH was disabled, follow this guide to re-enable SSH.

Restore Custom Startup Script
The firmware update overwrites your startup configuration. To restore your server or service auto-start functionality:

• Log in via SSH as root:

  ssh root@<your-nas-ip>


  Use soho as the username and your admin password if not changed.

• Launch the config editor:

  /opt/editconfig.sh


• In the nano editor that appears, scroll to Group 1 and insert the following code before the closing </Group> tag:

  <Program Name="init-opt.sh" Path="/opt/init-opt.sh">


  <SysOption Restart="-1"/>


  </Program>

  

  

• To save:

  • Press Esc

  • Press Ctrl + X

  • Press Enter to confirm the filename and save

⚠️ Warning: Double-check the placement of your inserted code. Any syntax error or misplacement can prevent your NAS from booting correctly. Only reboot if you’re confident the changes are correct.

Reboot NAS
Once you’ve saved the configuration correctly, reboot your NAS. Your custom startup script should now execute as intended on every boot.

 

Updating Firmware Up to Version 4.0.8.23976

For firmware versions below 4.1.102, the process is largely the same, with one small difference in where to insert the custom script reference.

Login and Update

• Log into your NAS web interface.

• Go to All Features > Software Updates.

• Download and upload the firmware file as described above.

• After uploading, the firmware will show as ready to apply. Click Apply to begin the update process.

SSH and Modify Startup Config

• After the update, login to your NAS via SSH using PuTTY or terminal.

• Launch the config editor:

  /opt/editconfig.sh


• In the nano editor, scroll down and find the <Program> block containing mozzyclient.
  Directly under it, insert the following block:

  <Program Name="init-opt.sh" Path="/opt/init-opt.sh">


  <SysOption Restart="-1"/>


  </Program>

  

  

• Save your changes (Esc, then Ctrl+X, then Enter) and review your file for accuracy.

Restart Your NAS
Once confirmed, reboot the NAS. Your custom init-opt.sh script will now execute during boot as before the firmware update.
