To update the firmware for your FNIRSI 1014D, you can use the official manufacturer's page or an community-developed open-source alternative. Official Firmware
The official firmware files and user guides are hosted on the FNIRSI Manuals & Firmwares page Look for the FNIRSI 1014D section on the support page. Installation Method:
Power on the device and connect it to your PC via a USB data cable. USB Export mode on the oscilloscope via USB export
A new drive will appear on your computer. Delete all existing files on this drive. Copy the new firmware file (typically named FSI-1014.bin ) directly into the root of this drive.
Eject the drive, disconnect the cable, and restart the device. The update should run automatically upon startup. Open Source Firmware (Community Alternative)
If you are looking for expanded features like improved triggering or a spectrum analyzer, there is a community-developed version available on GitHub: pecostm32/FNIRSI_1014D_Firmware
This project includes a boot loader that allows you to switch between different firmware versions at startup.
Community members note that the risk of bricking is low because the new firmware typically loads from the SD card, allowing you to revert to the factory state by deleting the file or swapping the card. Troubleshooting Common Issues Screen Shift:
If your screen appears shifted about 5mm to the left after an update, it usually means the firmware version for a different LCD panel was used. You should contact FNIRSI Support for the specific binary matching your hardware revision. Incorrect File Extension: Ensure the file is exactly named FSI-1014.bin . Some browsers may accidentally append a
extension during download, which will prevent the oscilloscope from recognizing it. Are you looking to fix a specific bug or are you trying to unlock new features with the open-source version? FNIRSI 1014D - How to do a Firmaware Upgrade Tutorial
Title: Where to Find the Official FNIRSI 1014D Firmware (And Why You Can’t Find the “Main” Link) fnirsi 1014d firmware link
Introduction If you own the FNIRSI 1014D (the popular 2-in-1 tablet oscilloscope and signal generator), you might eventually run into a bug, a boot loop, or simply want the latest features. But when you search for the firmware, you hit a wall.
Unlike most electronics, FNIRSI does not host the main firmware file (the .upg file) directly on their official product page. So, where is it?
The Official Download Portal FNIRSI consolidates all their firmware updates on a separate support server. You can find the 1014D firmware here:
👉 Official FNIRSI 1014D Firmware Download
Note: If the specific product ID link changes, simply go to fnirsi.com > Support > Download Center > Search "1014D".
What’s in the Zip File? When you download the zip, you will typically find:
How to Install (The Safe Way) Do not just drag and drop. Follow these steps exactly:
.upg file exactly to FNIRSI-1014D.upg (case sensitive).Warning: Version Checking FNIRSI has released multiple hardware revisions (V1.0, V1.1, V1.2). Installing the wrong firmware can lock your screen or invert the colors.
Can't find the link? Sometimes their server goes down. If the official link is dead, you can find verified mirrors on the EEVblog Forum (FNIRSI 1014D thread) or the FNIRSI Facebook User Group.
Final Verdict The 1014D is a great budget scope, but the firmware update process is clunky. Always keep a copy of your current firmware saved on your PC before attempting an update, just in case you need to roll back. To update the firmware for your FNIRSI 1014D,
Pro-Tip for your blog: I recommend downloading the file yourself, hosting it on Google Drive, and adding a "Mirror Link" below the official one. Readers love you for that.
It looks like you're looking for the firmware for the FNIRSI 1014D oscilloscope. This is a popular, budget-friendly 2-in-1 scope + signal generator, but finding official firmware can be tricky because FNIRSI doesn't always keep it prominently on their main site.
Here is the most reliable path to find the correct firmware:
1. The Official FNIRSI Support Forum (Best Source) FNIRSI hosts firmware and tools on their dedicated forum. Go to:
forum.fnirsi.com.upd file along with the USB driver (CH340) and the PC software (often called "FNIRSI 1014D Upper Computer").2. Google Drive / Mega Links (from official reps) FNIRSI support staff often post links in forums or YouTube comment sections. One commonly referenced path (still active as of recent months) is:
https://drive.google.com/drive/folders/1XrM... (You can find the exact live link by searching "FNIRSI 1014D firmware 2024" on YouTube – look for videos from channels like FNIRSI Official or DIY Projects).3. Critical Warning: Identify your hardware revision Before flashing, open your 1014D and check the PCB version (e.g., V1.3, V2.1, V3.0). Loading firmware for the wrong revision will brick the device (black screen, unresponsive buttons). Recovery requires disassembly and flashing via an ST-Link programmer.
4. How to check your current firmware version:
5. If you need to unbrick (no display after failed flash):
.bin or .hex – not the .upd (which is for USB update). You'll need the raw flash image from FNIRSI support (email: support@fnirsi.com – they usually reply within 1-2 days).Direct link (if still valid – test quickly):
https://www.fnirsi.com/download/1014d/FNIRSI-1014D-Firmware-V1.0.6.upd
(If that 404s, go tofnirsi.com→ "Support" → "Download" → "1014D".) Title: Where to Find the Official FNIRSI 1014D
Final tip: The most stable version for most users is V1.0.6. Newer beta versions (V1.0.8+) have been reported to break the signal generator or trigger calibration. Always keep a copy of your current firmware on your PC before updating.
If you're getting a 404 error or can't find it, reply with your current version and PCB revision – I can point you to a verified mirror.
FNIRSI maintains an official user group on Facebook where the developers frequently post the latest updates, beta versions, and direct Google Drive links. This is often the fastest way to get the newest files without navigating the Chinese website.
Keeping your FNIRSI 1014D updated ensures you get the most accurate measurements and the smoothest user experience. By sticking to the official links and following the steps above, you can safely upgrade your device in minutes.

We strongly advise against downloading firmware from random file-sharing sites, as corrupted files can brick your oscilloscope. Below are the official and safe sources:
A: Yes, but it requires a specific bootloader unlock sequence. FNIRSI does not officially support downgrading. Only do this if you experience severe instability.
.bin or .upd file from the official firmware zipBefore downloading anything, confirm your existing firmware to avoid unnecessary updates:
If your version is lower than the one available online, proceed with the update.
Even with the correct FNIRSI 1014D firmware link, things can go wrong. Here is how to fix the most frequent issues:
| Problem | Likely Cause | Solution |
|---------|--------------|----------|
| Oscilloscope won’t power on after update | Corrupted file or power loss | Reboot by holding power for 15 seconds. Use a different SD card. |
| White screen / No boot | FPGA mismatch | You need to also update the FPGA bitstream (included in official ZIP as a .rbf file). Repeat update with both files. |
| “Update file not found” | Wrong file name or path | Rename the file to FW1014D.bin (case sensitive). Ensure it’s not in a folder. |
| Touchscreen works but buttons don’t | Bootloader mismatch | Roll back to previous stable version (e.g., v1.2.0) then update again. |
