Before diving into the download, it is important to understand why an update might be necessary. FNIRSI frequently releases updates to address user feedback. Common reasons to update include:

Firmware is the software that is embedded in the device's memory, controlling its operation. For a device like the Fnirsi 1014D, firmware updates are crucial as they can enhance the device's performance, fix bugs, add new features, and improve compatibility with various operating systems or software tools.

Finding a reliable FNIRSI 1014D firmware link is the first step toward a smoother, more accurate measurement experience. To recap:

If you encounter any errors, join the FNIRSI Users Group on Facebook or the EEVblog forum thread titled “FNIRSI 1014D - Open Source & Firmware”. The community is active and helpful.

The FNIRSI 1014D firmware is essential for resolving bugs such as screen alignment shifts, voltage reading inaccuracies, and UI responsiveness. The latest official version is typically v3.0, though open-source alternatives exist for advanced users. 🔗 Official Firmware Resources

Download Portal: Access the FNIRSI Software Download Page for the official FSI-1014.bin file.

Alternative Link: Check the FNIRSI Manuals & Firmware section if the direct software link is unavailable. 🛠️ Update Procedure (Step-by-Step)

Updating the 1014D is straightforward but requires a specific sequence to avoid bricking the device. Preparation

Use a Micro-USB data cable (ensure it supports data transfer, not just charging). Download the official FSI-1014.bin file. Connection Power on the oscilloscope. Go to MENU → USB Export.

Connect the device to your PC; it will appear as an external drive (approx. 8GB). File Transfer

Crucial: Delete any existing files on the oscilloscope's drive before proceeding. Copy the new FSI-1014.bin file to the root of this drive. Execution Safely eject/unmount the drive from your PC. Disconnect the USB cable. Power the oscilloscope off and then back on.

A progress bar should appear, lasting about 20–60 seconds. The device will reboot automatically upon completion. 🔓 Open-Source & Custom Firmware

For users looking to extend the hardware's capabilities, independent developers have reverse-engineered the platform:

Pecostm32 Project: An Open-Source Firmware for 1014D on GitHub that offers a custom bootloader and potentially improved measurement filtering.

Safety Tip: Always backup your original firmware before experimenting with custom versions, as these are provided "as-is" without a warranty. ⚠️ Troubleshooting Common Issues

Screen Shift: If the UI is shifted to the left after an update, you likely installed the wrong version. Re-download the specific 1014D file and repeat the process.

SD Error: If the device fails to boot or displays an SD error, you may need to open the unit, remove the internal SD card, and reformat it on a PC before trying again.

Bricking Risk: Never interrupt power during the progress bar phase, as this can corrupt the FLASH memory. FNIRSI 1014D - How to do a Firmaware Upgrade Tutorial

Step 1: Prepare the SD Card

Step 2: Copy the Firmware File

Step 3: Power Down the Oscilloscope

Step 4: Initiate Update

Step 5: Completion

READ THIS FIRST: The FNIRSI 1014D and the FNIRSI 1013D look almost identical, but they use different internal chips.

Doing so will likely result in a "black screen of death" (a bricked device), requiring complex recovery procedures or rendering the oscilloscope useless. Always verify your model number on the back of the unit before proceeding.
