🐛 Troubleshooting

Theme not applying?

  • Ensure Termux is fully closed and reopened
  • Check that ~/.termux/properties has correct permissions
  • Try applying a different theme first, then your desired theme

Cyber Lock not working?

  • Verify password was set correctly (check for typos)
  • Ensure ~/.termux/.secure file exists and has correct permissions
  • Reinstall Cyber Lock if issues persist

Shell customization not visible?

  • Restart Termux completely
  • Check that the appropriate rc file (~/.zshrc, ~/.bashrc, etc.) was modified
  • Run bash os.sh again and reinstall

💡 Tips & Tricks

  1. Combine Features: Use Cyber Lock + Custom Banner + Color Theme together
  2. Fast Switching: Quickly change themes by running bash os.sh again
  3. Backup Configs: Always backup before major updates
  4. Performance: Bash with ble.sh may use slightly more resources; adjust if needed
