Fnirsi-1014d Firmware Update Work Link

The latest official firmware for the FNIRSI-1014D is version 3.0, which is designed to fix various bugs and display issues .

⚠️ Critical Warning: There are two different hardware versions of the 1014D due to different LCD manufacturers . If you install the wrong firmware version, your screen may shift to the left or right . If this happens, you must re-flash using the alternative version of the firmware file . 🛠️ Update Procedure

Download: Get the firmware files from the FNIRSI Official Download Page .

Connect: Plug the oscilloscope into your PC via a USB cable.

Export USB: On the device menu, select the USB Export option .

Prepare Drive: A new drive will appear on your PC. Delete all existing files on this drive first .

Copy File: Paste the new firmware file (e.g., FSI-1014.bin) onto the cleaned drive .

Restart: Disconnect the USB cable, power the device off, and then power it back on .

Auto-Update: The update routine will run automatically and typically finishes in under 2 minutes . 📂 Alternative & Recovery Options 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. The latest official firmware for the FNIRSI-1014D is

Eject and Power Off: Safely eject the drive from your computer and disconnect the USB cable. Power the oscilloscope off.

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

To update the firmware on your FNIRSI-1014D digital oscilloscope, follow these steps to ensure a safe and successful installation. Note that using the wrong firmware file can cause display issues like a shifted screen. Preparation Download the Firmware : Visit the FNIRSI Software Downloads page or the Manuals & Firmwares section to find the latest official Verify File Name : The firmware file must be named FSI-1014.bin for the device to recognize it during startup. Hardware Connection

: Use a high-quality Micro USB data cable to connect the oscilloscope to your PC. Update Procedure Enter USB Export Mode Turn on the oscilloscope. Navigate to the menu and select the USB Export USB Connection Access the Drive The “High-Res” Mode is Still a Lie

Your computer will recognize the device as a removable USB flash drive. Open the drive and delete all existing files to ensure a clean install. Transfer the Firmware FSI-1014.bin file onto the oscilloscope's drive. Finalize the Update Safely eject the USB drive and unplug the cable. the oscilloscope. the device again. The system will automatically detect the

file, verify its integrity, and write the new firmware to the internal FLASH memory. This usually takes less than one minute. Alternative: Open-Source Firmware For advanced users looking for extra features, there is an open-source project GitHub (pecostm32)

that offers alternative firmware and a bootloader. This allows for a startup menu to choose between different firmware versions. FNIRSI-1014D FNIRSI 1014D - How to do a Firmaware Upgrade Tutorial 3 Jun 2021 —

Real-World User Reports

| Aspect | Common Finding | |--------|----------------| | Improvements | Better FFT scaling, reduced noise on 10mV/div, faster UI response | | New Bugs | Some versions lose probe compensation output or corrupt saved screenshots | | Version Chaos | No official changelog – users rely on forum posts from v1.0.3 to v1.0.7 |

The Unfixed Frustrations

• The “High-Res” Mode is Still a Lie. It’s just average sampling. No real 12-bit emulation.
• The Measurement Font: Tiny. Microscopic. Still looks like 8-point Arial from a 2003 flip phone.

Phase 4: Current State (2024)

If you buy an FNIRSI-1014D today, here is the state of the firmware:

1. Out of the Box: Most units shipping now come with factory firmware that is "good enough." It is not as bad as the launch units. It is usable for basic debugging.
2. Community Firmware: It still exists and is superior in features and customization, but it is dangerous. It requires you to know exactly which FPGA your specific board has. The developers have updated their tools to detect hardware, but the risk of a "white screen of death" remains for casual users.
3. FNIRSI's Support: FNIRSI posts updates on their Facebook page or via Google Drive links shared in enthusiast groups. They generally do not have a polished "support portal" on their main website.

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.

The Heroic Fixes (Bravo, FNIRSI)

1. The Cursor Lag is DEAD. On original firmware, moving cursors felt like dragging a cat through mud. Update 1.0.4+ made cursor response instant. This alone is worth the update.
2. Trigger Stability on Noisy Signals. Old firmware would false-trigger on ripple like a nervous heart. The new algorithm (they claim a rewritten trigger engine) actually holds steady on a 5mV/div signal. It’s not a Rigol, but it’s no longer guessing.
3. FFT is Usable. Previously, the FFT was a joke—a jagged mess with no peak hold. Now? You can actually find a 10kHz tone in a switching supply noise. It’s basic, but it works.
