Before starting the update process, gather the following items to prevent bricking your device:

The DSO-TC2 has two separate parts, each requiring its own firmware update: Oscilloscope Firmware: Files typically start with CHD . Transistor Tester Firmware: Files typically start with MM . Required Tools: FNIRSI DSO-TC2 Device fnirsi dso-tc2 firmware

When the display prompts you to isolate the pins (around 25% to 30% progress), remove the short-circuit wire. Let the process finish completely. To Calibrate the Oscilloscope: Disconnect all probes from the MCX/BNC input. Navigate to the menu and select .

Unlike major brands like Rigol or Siglent, FNIRSI does not host a centralized, official "download center" for legacy firmware. Firmware updates are typically distributed via:

: Most FNIRSI flashing tools are built strictly for Windows environments.

Once the copy is finished, safely eject the drive from Windows. Unplug the USB cable. What or hardware revision is shown on your

The FNIRSI DSO-TC2 uses an STM32 microcontroller, which has open-source toolchains. A small community has created :

FNIRSI is notoriously secretive about changelogs, but the community has tracked improvements. Here’s a timeline: This link or copies made by others cannot be deleted

Enhances the accuracy of the transistor tester when identifying BJTs, MOSFETs, diodes, and resistors.

: Download the official .bin or .hex file alongside the manufacturer’s flashing software. Step-by-Step Firmware Update Process Follow these steps carefully to update your device. 1. Download the Official Files

Ensure the device is truly in bootloader mode. Try lowering the baud rate in the flashing software to 9600 or 57600 to create a more stable connection. White Screen After Update

The firmware’s UI is where the DSO-TC2 shows its consumer-facing polish. The 2.8-inch 320×240 IPS display is bright and legible, and the firmware uses large icons and simple menus. Navigation is via four buttons and an encoder wheel—a common control scheme for pocket scopes.

Switch to a different USB port (preferably on the back of the motherboard if using a desktop). Ensure you are not using a charge-only cable. Reinstall the CH340 drivers. Flashing Tool Fails at 0% or Times Out
