In high-risk industrial environments such as oil and gas, chemical processing, and manufacturing, safety is a top priority. Every piece of technology used in these settings must not only function effectively but also meet stringent safety standards. Among these are ATEX-certified tablets, which are built for safe use in explosive atmospheres.
Like any modern smart device, ATEX tablets rely on firmware—low-level software that controls hardware functionality. Manufacturers periodically release firmware updates to improve device performance, patch vulnerabilities, and add new features. However, updating firmware on an ATEX tablet isn’t as straightforward as on consumer devices. Due to safety protocols and environmental constraints, the process must be handled with care and in compliance with certification standards.
This comprehensive guide will walk you through how to update firmware on your ATEX tablet safely and effectively, helping you avoid common pitfalls while maximizing the performance and safety of your device.
What Is Firmware and Why Does It Matter?
Firmware is the embedded software that governs a device’s core operations. On an ATEX tablet, it controls critical functionalities such as power management, sensor integration, wireless communication, and even how the device interacts with certified peripherals.
Updating this firmware is essential because it:
Improves performance and battery efficiency
Fixes software bugs and vulnerabilities
Ensures compatibility with newer applications
Enhances system stability under extreme environmental conditions
Maintains certification integrity and manufacturer compliance
For ATEX tablets, these updates not only enhance functionality but also uphold the safety requirements mandated for hazardous locations.

Which ATEX Tablets Require Firmware Updates?
Not all ATEX tablets have the same update procedures or requirements. Most intrinsically safe tablets used in industrial environments run Android or Windows-based systems. Some models may receive firmware via OTA (Over-The-Air) updates, while others may need manual intervention using a USB connection or proprietary software.
Here are some commonly used ATEX tablets:
Popular ATEX-Certified Tablet Models
Tablet Model | Operating System | Update Method | Zone Certification |
---|---|---|---|
Ecom Tab-Ex 03 DZ1 | Android | OTA & USB (via Ecom Suite) | Zone 1/21 |
i.Safe MOBILE IS930.1 | Android | USB / SD card | Zone 1/21 |
Getac ZX70-EX | Android | OTA | Zone 2/22 |
Aegex 100M Intrinsically Safe Tablet | Windows | Manual (via USB drive) | Zone 1/Division 1 |
Sonim RS80 IS | Android | OTA / Manufacturer Utility | Class I, Division 1 |
Knowing your model and its supported update method is the first step in proceeding safely with the firmware upgrade.
Pre-Update Checklist: Prepare for a Smooth Update
Before beginning the update, ensure you’ve taken all necessary precautions. Updating firmware in a hazardous environment is not a task to take lightly.
1. Identify the Tablet Model and Firmware Version
Go to the device settings and locate the “About Tablet” section. Record the current firmware version and hardware model number. This ensures you download and install the correct firmware update for your specific unit.
2. Fully Charge Your Device
Make sure your tablet is at least 80% charged or connected to a stable power source. Losing power during an update can result in firmware corruption, potentially bricking the device.
3. Back Up Important Data
Firmware updates can sometimes reset settings or even wipe data. Use the tablet’s built-in backup tools or an external drive to save important files, settings, and applications.
4. Remove Non-Essential Peripherals
Disconnect any accessories such as barcode scanners, keyboards, or Bluetooth devices. This avoids conflicts during the firmware flashing process.
5. Read Manufacturer Instructions
Each brand may have a slightly different update procedure. Visit the manufacturer’s support page or user manual to understand specific instructions or tools required for your model.
Step-by-Step: How to Update Firmware on an ATEX Tablet
Follow these general steps to safely perform a firmware update. Always consult your tablet’s specific documentation before proceeding.
Step 1: Check for Firmware Availability
Navigate to Settings > System > Software Update on your device. If your device supports OTA updates, it will show the latest firmware available. Alternatively, check the manufacturer’s website for downloadable firmware packages if updates must be installed manually.
Step 2: Download the Update
For OTA updates, select “Download” when prompted. For manual updates, download the firmware package onto a USB stick or SD card, ensuring that it is the correct version for your model.
Step 3: Connect to a Secure Network
Make sure the tablet is connected to a secure Wi-Fi network. Avoid using public or unstable connections during the download or update process.
Step 4: Begin Installation
Once the update is ready, select “Install Now.” The device may restart multiple times during this phase. If using manual installation, connect the USB or SD card and follow on-screen prompts or boot into recovery mode if instructed.
Step 5: Wait for Update Completion
Do not power off or reboot the tablet during this process. Interruptions can corrupt the firmware and may void certifications.
Step 6: Confirm Successful Installation
After reboot, go back to Settings > About Tablet and verify that the firmware version has been updated.
Post-Update Actions
Reconfigure Your Settings
Some updates reset configurations to default. Reconnect to your network, sign in to apps, and re-enable location or safety features as needed.
Reinstall Critical Apps
If any applications were removed during the update, reinstall them from approved sources.
Run a System Diagnostic
Use built-in tools or manufacturer software to run a quick health check. This ensures all sensors and functions are operating properly post-update.
Common Issues During Firmware Updates (and Fixes)
The Update Fails to Start
Verify your battery is charged
Ensure enough storage space is available
Confirm the update file is compatible with your device
Tablet Becomes Unresponsive
Try a hard reset using power + volume buttons
If issues persist, contact support and do not attempt to flash unofficial firmware
Update Stalls Midway
Do not disconnect power
Wait 15–20 minutes before attempting a forced restart
Use manufacturer’s recovery utility if available
FAQs: Updating Firmware on ATEX Tablets
Can I update the firmware while in a hazardous zone?
No. All firmware updates should be performed in a non-hazardous environment unless the device supports safe OTA updates and the process is permitted under your site’s safety regulations.
How often should firmware updates be performed?
Check for updates quarterly or as advised by the device manufacturer. Do not postpone critical updates that address vulnerabilities or compliance issues.
Will updating firmware affect ATEX certification?
Not if you follow the manufacturer’s approved update process. Installing unofficial firmware or modifying system files can compromise certification.
What should I do if I see an “incompatible firmware” error?
Stop the installation immediately. This typically means the update file doesn’t match your tablet model or hardware version. Download the correct version from the manufacturer.
Can I roll back to a previous version?
Some tablets support rollback, but not all. If needed, contact the manufacturer’s support team before attempting a downgrade.
Best Practices for ATEX Tablet Firmware Maintenance
Use only official firmware from the manufacturer
Maintain a firmware update log for audit purposes
Establish a regular update schedule across all field devices
Train technicians on model-specific update procedures
Avoid rushed updates in critical environments—always assess risk first
Conclusion
Updating the firmware on your ATEX tablet is a routine yet essential maintenance task that ensures continued safety, regulatory compliance, and operational efficiency. Unlike consumer tablets, ATEX-certified devices operate under strict environmental and safety constraints, meaning that updates must be approached methodically.
By following this step-by-step guide, you can confidently manage firmware updates while preserving your device’s performance and certification integrity. A little preparation goes a long way in preventing technical disruptions or compliance issues in high-stakes industrial environments.
