Key Points
- Firmware operates at a low level within devices such as computers, routers, smartphones, IoT devices, and enterprise equipment, directly managing processors, memory, and networking hardware.
- Firmware manufacturers release updates to patch vulnerabilities, fix bugs, optimize system stability, and ensure compatibility with modern operating systems and applications.
- Unpatched firmware can expose devices to exploits, ransomware, and hardware failures while limiting access to new features and performance enhancements.
- Firmware installation methods vary by device and may involve over-the-air (OTA) updates, USB connections, BIOS/UEFI tools, or management software.
- Interrupting power or disconnecting during firmware updates can result in bricked hardware, making backups and stable power sources essential.
- Centralized endpoint management and update automation tools help maintain firmware compliance, reduce vulnerabilities, and streamline firmware lifecycle management at scale.
Most endpoint devices today, from computers and tablets to smartphones and routers to cars and appliances, rely on a combination of hardware and software to function correctly. The hardware inside these devices requires a specific type of programming, called firmware, to run.
What is firmware?
Firmware is a type of software containing a set of instructions that determines how a device’s hardware operates and functions. They are installed directly onto components such as memory chips or graphics cards in electronic devices.
Unlike regular software, which can be easily installed or updated, firmware is permanently embedded into the hardware and, therefore, requires different methods to update it.

What is a firmware update?
A firmware update is the process of upgrading the firmware installed on a device by altering its code. Firmware updates typically come from the device manufacturer and are designed to fix bugs, improve performance, enhance security, and introduce new features.
How to update firmware depends on the device, and updates can be delivered through various channels, such as over-the-air through Wi-Fi, USB connections, or through computer software provided by the manufacturer.
Why is updating firmware important?
Keeping firmware up to date improves the functionality and overall user experience of your devices through the following benefits:
Security enhancements
Firmware updates often include security patches that address vulnerabilities and protect your device from potential cyber threats. Failing to update your firmware leaves your device vulnerable to attacks and compromises your personal data.
Bug fixes
Just like any software, firmware can have bugs or glitches that impact the performance of your device. Firmware updates frequently address these bugs, resulting in a smoother and more stable operation.
Improved compatibility
As technology advances, firmware updates ensure that your device remains compatible with the latest software and hardware developments, allowing you to take advantage of new features and functionalities.
Optimized performance
Firmware updates often include performance optimizations that enhance the speed and efficiency of your device. These improvements can lead to faster boot times, smoother multitasking, and improved overall performance.
Keeping your devices up to date with the latest firmware versions ensures that your devices are secure and benefit from improved performance and compatibility.
What happens if you don’t update firmware?
Ignoring firmware updates can negatively impact your device’s security, performance, compatibility, and overall user experience, including:
- Security risks: Without the latest firmware updates, your device may be vulnerable to security breaches and hacking. Cybercriminals often target outdated firmware to exploit vulnerabilities and gain unauthorized access to your device or personal information.
- Compatibility issues: Without firmware updates, your device may struggle to work with newer software or hardware, resulting in compatibility issues, crashes, and errors, or even render your device unusable.
- Poor performance: Firmware updates often include performance optimizations that improve the speed and efficiency of your device. Not updating means you miss out on these improvements and may experience slower operations, lag, or freezing.
- Missing out on new features: Firmware updates often introduce new features or functionalities that enhance your device’s capabilities. By not updating, you limit the potential of your device.
How to know if firmware needs to be updated
To determine if your device’s firmware needs to be updated, follow these practices:
Manually check the firmware’s current version
You can determine which version of firmware your device is currently running by accessing Settings or the Admin Panel. Likewise, you can also visit the manufacturer’s site to check on the latest firmware for your device’s model.
Stay notified on official channels
Many devices typically notify users of the latest firmware version’s availability via on-screen messages and emails. Be sure to monitor these notifications.
Look out for performance and security issues
Devices often exhibit signs of being outdated, such as slower performance and response times, frequent crashes, security alerts, and compatibility issues, among others. Always stay alert for these signs and check if these issues are firmware-related.
How to update firmware on different devices
Identifying a firmware update for your device and how to update firmware varies depending on the manufacturer and the device itself. Before you begin, consult the device’s user manual or the manufacturer’s support page for detailed instructions on how to update firmware. If you don’t have the user manual, follow these steps.
1. Identify the device model and manufacturer
Identify the device model and manufacturer before you begin by checking the device itself or the user manual. Keep this information at hand to help you find firmware updates for your device.
2. Check for firmware updates
Visit the manufacturer’s official website or support page and look for a section dedicated to firmware updates or downloads for your device model. Here, you should find the latest firmware version available for your device.
3. Download the firmware update
Download the appropriate firmware update for your device to your computer or directly to the device, as instructed by the manufacturer. Make sure to save it in an easily accessible location and remember its file name.
4. Connect the device and install the firmware update
Connect your device to your computer using a USB cable or by following the specific instructions provided by the manufacturer, or go straight to your device. Locate the firmware update file you downloaded and follow the on-screen instructions to install the update. Please read and follow all the steps carefully to avoid any potential issues.
5. Wait for the update to complete
During the firmware update process, your device may restart multiple times or display progress indicators. Allow the update process to complete without interruption to avoid corrupted firmware or even permanent damage to your device.
6. Verify the firmware update
After completing the update, verify that the firmware update was successful. Check the device settings or the manufacturer’s instructions to confirm that the updated firmware version is now installed on your device.
Best practices for updating firmware
While updating firmware is a fairly straightforward process, following these best practices will ensure that your update is successful and that errors are minimal.
Back up your data.
Always back up your device’s data before updating firmware to ensure that important files and settings are protected in the event that something goes wrong during the update process.
Read the instructions.
Carefully read and follow the manufacturer’s instructions on how to update firmware. Each device may have its own specific requirements or recommendations, and it’s essential to follow them to avoid any potential issues.
Use a stable power source.
Ensure that your device is connected to a stable power source during the firmware update process. A sudden power outage or interruption can result in a failed update and potentially damage your device.
Don’t interrupt the update.
Don’t disconnect or turn off your device during the firmware update process. Allow the update to complete uninterrupted to minimize the risk of firmware corruption or device malfunction.
Keep the updated firmware files.
After successfully updating your device’s firmware, it is a good practice to keep a copy of the firmware update file. Having a backup allows you to reapply the update in case you need to reset your device or reinstall the firmware in the future.
