By following these simple steps, users should be able to successfully update the firmware of their Fnirsi 1014D device.

Failing to prepare properly can result in a "bricked" device (a completely unresponsive oscilloscope). Ensure you meet these requirements before proceeding:

Download the correct .bin update file and the flashing software tool directly from the official FNIRSI website or their authorized support forums.

Power off the FNIRSI-1014D completely using the physical power button.

This community firmware is hosted on GitHub in repositories such as pecostm32/FNIRSI_1014D_Firmware and Donwulff/FNIRSI_1014D_Firmware . The project is a result of hacking the original FNIRSI 1013D and 1014D firmware, with the goal of creating a fully open-source implementation.

Paste the file directly into the of the oscilloscope's drive. Do not place it inside any folders. Wait for the file transfer to complete entirely. Step 4: Finalize the Update

Updating the firmware is not just about having the latest version; it's about improving the device's functionality. Based on community feedback and manufacturer updates, the latest firmware versions (often v3.0 or later) provide:

Look for a new removable drive labeled as a generic USB storage device.

Swap the USB port. Avoid USB 3.0 (blue ports) if you encounter glitches; older USB 2.0 ports are significantly more reliable for flashing legacy microcontrollers.
