In the quiet hum of my lab, the FNIRSI 1014D oscilloscope sat like a stubborn companion. I’d heard the whispers on EEVblog about Version 3.0 firmware, promising a smoother interface and better stability. But as every tinkerer knows, "updating" is often a polite word for "danger." The Preparation
I began by scouting the official FNIRSI support page. The file I needed was elusive—some links were dead ends, but persistence led me to a .zip containing the magic FSI-1014.bin file.
Important: There are two different LCD manufacturers for this model. If you pick the wrong one, your screen might shift or distort. I downloaded both versions, just in case. The Operation
The Handshake: I grabbed a standard USB-A to USB-A cable—a rarity in most setups, but the lifeblood for this scope.
USB Export: On the 1014D, I hit MENU and navigated to USB export. The PC chirped as it recognized a new 8GB drive.
The Clean Slate: Per the instructions, I deleted every existing file on that internal drive. It felt like clearing a path through a digital forest.
The Transfer: I dragged FSI-1014.bin onto the drive. I didn't rush; I even used the Linux sync command to ensure every bit was truly there. The Reckoning
I disconnected the cable and hit the power switch. The FNIRSI logo flashed twice. A thin horizontal progress bar crept across the bottom of the 7-inch screen. It took less than a minute, but in the silence of the lab, it felt like an eternity.
The device rebooted. The interface was crisp, the parameters were aligned, and—most importantly—the firmware showed V3.0. Troubleshooting the "Ghost in the Machine" fnirsi1014d firmware update work
If you find your screen has shifted or "fallen off" the edge, don't panic:
Wrong Version: This usually means you used the firmware for the other screen type. Re-run the process with the second .bin file provided in the update package.
SD Errors: If it refuses to boot, you may need to open the unit and format the internal SD card directly on your PC.
Pro-Tip: If you’re feeling adventurous, there are community-led reverse-engineering projects on GitHub that offer custom bootloaders and experimental features.

Guide to Updating the FNIRSI 1014D Go to product viewer dialog for this item. Updating the firmware on your FNIRSI 1014D
digital oscilloscope can resolve display issues, improve system stability, and occasionally add new software features. Because FNIRSI has used different hardware components (specifically different screens) over time, the update process requires careful file selection to avoid screen-shift errors. Preparation Requirements Before starting, ensure you have the following:
USB Data Cable: A high-quality cable for connecting the oscilloscope to your PC. In the quiet hum of my lab, the
Latest Firmware File: Downloaded from the Official FNIRSI Support Page. The file is typically named FSI-1014.bin.
Backup: It is highly recommended to back up any existing waveforms or settings on your device before proceeding. Step-by-Step Update Process
Enter USB Export Mode: Power on the oscilloscope, enter the main menu, and select the USB Export option.
Connect to PC: Plug the device into your computer. It should appear as a new removable drive.
Clean the Drive: Open the new drive and delete all existing files. Do not format the drive unless the device is bricked and you are following a recovery procedure.
Transfer Firmware: Copy the downloaded .bin firmware file into the root directory of the oscilloscope's drive.
Eject and Reboot: Safely disconnect the USB cable from the PC and the oscilloscope. Power the device off and then back on. The update should initiate and complete automatically within seconds. Troubleshooting Common Issues
Screen Shift to the Left: This is a known issue caused by using a firmware version incompatible with your specific LCD hardware. To fix this, you must redo the update using the "alternative" version of the firmware (often labeled as a different screen version) provided by FNIRSI Support. Bootloader Mode: The FNIRSI 1014D has a dedicated
Device Won't Boot (Bricked): If the device shuts down immediately after the boot screen, the SD card inside may be corrupted. Some users resolve this by opening the device, removing the internal SD card, and reformatting it to FAT32 on a PC before reloading the firmware files.
USB Connection Fails: Ensure you are using the "USB Export" menu item; the device will not be recognized as a drive by the PC if this mode is not active. Alternative: Custom Open Source Firmware FNIRSI 1014D - How to do a Firmaware Upgrade Tutorial
Failure to prepare correctly can result in a "bricked" device. Ensure the following conditions are met before proceeding:
Understanding the internal process will help you avoid mistakes. Here is exactly how the update works step-by-step at a technical level:
FNIRSI_1014D_Vxx.xx.upd), the bootloader compares the version number with the current firmware.When users ask, “does the fnirsi1014d firmware update work reliably?” — the answer is yes, provided you follow the correct sequence. Most failures are due to user error, not a flawed update mechanism.
Test Your Device: Run some tests to ensure everything is working as expected. Try out different functions to verify they are operating correctly with the new firmware.
Backup Your Settings: If you had custom settings or profiles saved before the update, you might want to back them up if possible, to easily restore them.
A: Possibly not. Genuine FNIRSI 1014D units have a serial number sticker. Counterfeits use different hardware and flashing them with official firmware will brick the device. Buy from authorized sellers.
The FNIRSI-1014D is a popular entry-level dual-channel digital storage oscilloscope (DSO) known for its compact form factor and responsive touch screen. Like many modern embedded devices, its functionality relies heavily on internal firmware. Updating this firmware is essential for bug fixes, feature enhancements, and UI improvements.
This document details the necessary preparations, the step-by-step execution, and critical troubleshooting for the firmware update process.
