For advanced users, the open-source community has developed custom alternative firmware variants for the FNIRSI-1014D. These custom builds often fix foundational hardware-limitation bugs that official updates ignore, such as unlocking better digital filtering and optimizing memory depth navigation. If you choose to use community mods, ensure you back up your original factory calibration data, which is sometimes stored on an internal EEPROM chip.
Unzip the downloaded folder to locate the core file, usually named 1014d.bin or F1014D.bin . Step 2: Boot the Device into USB Update Mode Ensure the FNIRSI-1014D is completely powered off.
Properly "eject" or "unmount" the 8GB drive from your computer 1.2.4. fnirsi1014d firmware update work
Toggle the power switch off, wait 5 seconds, and turn it back on.
This community firmware is hosted on GitHub in repositories such as pecostm32/FNIRSI_1014D_Firmware and Donwulff/FNIRSI_1014D_Firmware . The project is a result of hacking the original FNIRSI 1013D and 1014D firmware, with the goal of creating a fully open-source implementation. For advanced users, the open-source community has developed
If the screen shifts or acts erratically after the update, you may have used an incorrect firmware version. Search for specialized forum threads (e.g., on EEVblog ) to find the correct FSI-1014.bin for your specific panel version. Conclusion
Updating the firmware is not just about having the latest version; it's about improving the device's functionality. Based on community feedback and manufacturer updates, the latest firmware versions (often v3.0 or later) provide: Unzip the downloaded folder to locate the core
The internal bootloader did not detect the file. Ensure the file extension is strictly .bin and not hidden as .bin.txt . Ensure the drive was formatted to FAT32, not exFAT or NTFS.
He plugged it in. The boot time was instant. The UI was fluid. He connected the probes to the calibration terminal, expecting a perfect square wave.
Reduces lag when switching between menus and adjusting waveforms.
