Fnirsi-1014d Firmware Update: Link

The FNIRSI-1014D firmware update process involves manually transferring a FSI-1014.bin file from a PC to the oscilloscope while it is in a specific USB export mode. Users should be cautious, as installing the wrong version of the V3.0 firmware can cause the screen to shift or display parameters to become obscured due to different hardware screen versions used in manufacturing. Essential Update Steps

Obtain Firmware: Download the latest file from the FNIRSI Support Page. If the link is broken, some users have successfully edited the URL or contacted FNIRSI support directly for the file.

Connect to PC: Use a USB data cable to connect the oscilloscope to your computer.

Enter USB Export Mode: In the oscilloscope's menu, select the USB export option. The device will appear as a new drive on your PC.

Prepare the Drive: Delete all existing files from the oscilloscope's drive before copying the new FSI-1014.bin file into it.

Initiate Update: Safely disconnect the USB cable and power the device off. Turn it back on to trigger the automated installation. Troubleshooting & Known Risks

Screen Shift Issues: If your display shifts to the left or right after updating, you likely installed the version intended for a different screen hardware. Re-running the update with the "other" version of the firmware typically fixes this.

Hardware Variants: Early units often had bugs like inverted channel coupling indicators or incorrect measurement values, which newer firmware seeks to correct.

Alternative Solutions: For advanced users, there are community efforts on GitHub dedicated to reverse-engineering the firmware to fix deep-seated bugs.

Power Stability: Avoid updating if your power source is unstable. Some users reported "crazy" voltage readings that were actually caused by ground loops from shared USB power supplies rather than firmware errors. FNIRSI 1014D - How to do a Firmaware Upgrade Tutorial

is a critical maintenance task that can resolve display bugs, improve performance, and potentially unlock new features. As of early 2026, the current official firmware version for the FNIRSI-1014D is Version 3.0. Why Update Your Firmware? Firmware updates for the FNIRSI-1014D

typically address stability issues or hardware compatibility. One of the most common reasons for an update is to fix an offset or shifted screen, which occurs because FNIRSI used two different screen hardware versions during production. Using the correct firmware "version" (there are two variants of V3.0) ensures your display aligns perfectly. Prerequisites for the Update

Hardware: A USB "A-to-A" data cable (though non-standard, it is required for this device).

Power: Ensure the oscilloscope is connected to a stable power source. An interruption during the update can brick the device.

Software: Download the FSI-1014.bin file from the official FNIRSI Support Page. Step-by-Step Update Process FNIRSI-1014D uses a straightforward "drag-and-drop" method via USB.

Enter USB Mode: Power on the oscilloscope. Navigate to MENU and select USB Export.

Connect to PC: Plug the A-to-A USB cable into the oscilloscope and your computer. A new 8GB drive will appear on your PC.

Prepare the Drive: Open the new drive and delete any existing files.

Copy Firmware: Drag and drop the FSI-1014.bin file onto the root of the oscilloscope's drive.

Eject and Power Off: Safely eject the drive from your computer and disconnect the USB cable. Power the oscilloscope off. Phase 1: Prepare the SD Card The FNIRSI-1014D

Initiate Update: Power the device back on. The startup screen should appear twice, followed by a progress bar. This process typically takes about 20 seconds.

Auto-Reboot: Once the bar fills, the device will reboot automatically with the new firmware active. Troubleshooting Common Issues

Shifted Screen: If your screen parameters are shifted to the left or right after the update, you have installed the firmware for the "other" screen hardware version. Simply repeat the process using the alternative V3.0 .bin file provided by FNIRSI support.

Update Not Starting: Ensure the file is named exactly FSI-1014.bin. The system specifically checks for this filename at startup.

Failed Update/Black Screen: If a bad flash occurs, you may need to open the device and manually format the internal 8GB micro SD card before trying again. Advanced & Custom Firmware

For enthusiasts looking beyond official support, community-driven projects on GitHub have experimented with reverse-engineering the 1014D firmware to improve UI elements or data handling. However, these are unofficial and carry a higher risk of bricking your unit. Reverse engineering the FNIRSI 1014D - EEVblog

, you generally need to place a specifically named file on the device's internal storage and restart it. While official support can sometimes be inconsistent, community members and technical forums like EEVblog have documented the process extensively. Latest Known Version

As of April 2026, the most recent stable official firmware version for the remains v3.0 (often dated around October 2021). Firmware Update Procedure

Obtain the Firmware: Download the latest firmware file, typically named FSI-1014.bin, from the FNIRSI Software Download page or community-verified links. Connect to PC : Connect your FNIRSI-1014D to your computer using a USB "A" to "A" cable. Insert the microSD card into your PC

Enable USB Export: On the oscilloscope, go to MENU → USB export. The device should appear on your computer as an approximately 8GB external drive.

Transfer the File: Copy the FSI-1014.bin file directly to the root directory of this drive.

Safety First: Eject or unmount the drive properly from your PC to ensure the file is fully written.

Initiate Update: Disconnect the USB cable, turn the oscilloscope off, and then back on. The device will detect the update file at startup, display a progress bar for about 20 seconds, and then reboot automatically. Common Issues & Troubleshooting

Screen Shift/Offset: There are two different screen hardware versions for the

. If your screen appears shifted or distorted after an update, you likely need the "other" version of the v3.0 firmware provided by FNIRSI to match your specific display.

Black Screen/Non-Booting: If the device fails to boot after a bad update, some users recommend opening the device to manually format the internal SD card or using a firmware loader tool to restore the original data.

Alternative Firmware: For advanced users, open-source reverse-engineered firmware exists on GitHub, which sometimes offers improved features like custom boot loaders.

Phase 1: Prepare the SD Card

The FNIRSI-1014D is picky about SD cards. It usually requires FAT32 format with a Master Boot Record (MBR) .

1. Insert the microSD card into your PC.
2. Right-click the drive in Windows Explorer and select Format.
3. Set File System to FAT32.
4. Set Allocation Unit Size to 4096 bytes (or Default).
5. Uncheck "Quick Format" (perform a full format to clear bad sectors).
6. Click Start.

The “Why Did They Change That?” (The Weird)

• UI Color Scheme: They darkened the grid lines. Some love it (less eye strain), some hate it (harder to see at a glance). No option to switch back.
• Button Repeat Rate: The physical buttons now have a delayed repeat when held down. Want to scroll 20ms of timebase? Hold the button and wait. It’s slower than before. Why?

Conclusion: To Update or Not to Update?

For 99% of users, the rule is simple: If it ain't broke, don't fix it. If your FNIRSI-1014D is stable and you are not missing any specific features, leave it alone.

However, if you are experiencing persistent bugs, need a specific decoding feature, or simply want the best possible performance, a FNIRSI-1014D firmware update is a straightforward process—provided you respect the hardware revision and SD card requirements.

By following this guide, you can breathe new life into your trusty oscilloscope, ensuring it remains a reliable companion on your workbench for years to come. Just remember: double-check that sticker on the back before you hit that power button. Your oscilloscope’s life depends on it.
