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.

Leo sat in his cluttered workshop, the smell of solder and ozone thick in the air. On his bench lay his trusty FNIRSI-1014D, a budget-friendly powerhouse that had seen him through dozens of projects. Lately, though, it had been acting up—a bit of lag here, a flickering waveform there. He knew it was time for a firmware update, but the prospect always made him a little nervous.

He pulled up the FNIRSI support page on his laptop. Navigating the site, he found the latest update file: FSI-1014.bin. With a click, the small file began to download.

Leo reached for a USB cable—the unusual "A" to "A" type required for this specific device. He clicked the oscilloscope's power button and navigated through the digital menu: MENU > USB export.

"Alright, let's see," Leo muttered. A new drive appeared on his computer screen. He followed the community advice he’d read: he carefully deleted all the old files from the oscilloscope’s internal storage to make room for the new.

He dragged the FSI-1014.bin file onto the now-empty drive. It was a tiny file, and the transfer bar finished in a blink. He safely ejected the drive—a crucial step he never skipped—and unplugged the USB cable.

Now for the moment of truth. Leo toggled the power switch: Off, then On.

The screen flickered. The FNIRSI logo appeared once, then twice. Suddenly, a horizontal progress bar stretched across the 7-inch display. Leo held his breath. For twenty long seconds, the bar crawled toward the finish line.

The device rebooted itself. The screen glowed a crisp, steady blue. Leo hooked up a probe to the built-in signal generator and watched a perfect, sharp square wave bloom on the display. No lag, no flicker.

"Good as new," he smiled, already reaching for his next project. 🛠️ Quick Summary of the Process

If you're looking to update your own FNIRSI-1014D, here is the standard workflow: Bug fixes : Firmware updates often address bugs

Download: Get the latest FSI-1014.bin from the official FNIRSI website.

Connect: Use a USB-A to USB-A cable and set the scope to USB Export mode in the menu.

Clean: Delete existing files on the oscilloscope's internal drive before copying the new one.

Transfer: Copy the .bin file to the device and eject safely.

Install: Unplug the USB, power the unit off, and then back on. The update will run automatically.

⚠️ Warning: Ensure your power source is stable. A power loss during the 20-second update bar can brick the device. If your screen appears shifted or distorted after the update, you may have used the wrong firmware version for your specific screen hardware.

Are you currently experiencing an error (like a shifted screen or "SD error")?

4. Extended Hardware Compatibility

FNIRSI occasionally changes internal components (like the display driver or touch controller) due to supply chain issues. A firmware update ensures your software matches your specific hardware revision.

Phase 3: Flash the Oscilloscope

Power off the FNIRSI-1014D completely.
Insert the microSD card into the slot on the side of the scope (usually on the right side, near the probe compensation output).
Connect the USB power cable. Do not use a battery pack that can cut out.
Press and hold the "Trigger" button (or sometimes the "Menu" button—check your readme file). For most versions, you hold the "User" (UTIL) button.
While holding the button, press the Power button to turn the scope on.
Keep holding the secondary button until you see a screen message. You should see:
- "Upgrading..."
- A progress bar.
- A message like "Programming NOR Flash."

Phase 2: Load the Firmware

Copy the firmware .bin file directly to the root directory of the microSD card.
Do not rename the file unless the official instructions tell you to (most require the exact original name like 1014D_V43_V104.bin).
Do not place it inside a folder.
Safely eject the SD card from your PC.

Advanced: Third-Party and Open-Source Firmware

There is a cult following for the FNIRSI-1014D that has produced custom firmware. Notably, the envox and open-dso projects offer enhanced features like higher FFT bins, network streaming, and bug fixes that FNIRSI has ignored.

Warning: Flashing third-party firmware voids your warranty and carries a bricking risk. However, if you are adventurous, these projects often provide superior performance. Always read the project's hardware compatibility matrix.

3. New Features

While the 1014D doesn't receive radical new features frequently, some updates have introduced:

Improved signal generator modes (on units that include the AWG function).
Additional decoding protocols for the bus analysis feature (I2C, SPI, UART, etc.).
Better screenshot saving formats.

The Warning: Know Your Hardware Revision

This is the single most critical step. If you ignore this, you risk bricking your oscilloscope.

The FNIRSI-1014D has at least three distinct hardware revisions. The firmware is not cross-compatible. You cannot flash a v4.3 board firmware onto a v3.0 board.
