Ensure there are no short circuits in the 1-2-3 test sockets during the initial phase. If it continues to fail, the firmware flash may have been corrupted; perform a clean re-flash of the firmware. Conclusion

Swap out the USB-C cable. Many modern USB cables are only wired for charging and lack data lines. Ensure the device is powered on or correctly forced into bootloader mode. 2. Flashing Fails Mid-Way or Throws a Timeout Error fnirsi dsotc2 firmware

Lower the baud rate in your flashing software to 9600 or 115200. High baud rates can cause data corruption over longer or unshielded USB cables. 3. The Device Has a Blank Screen After Flashing (Bricked) Ensure there are no short circuits in the

The FNIRSI DSO-TC2 firmware is a functional but unoptimized implementation of a portable oscilloscope and component tester. Its lack of cryptographic protections makes it an ideal learning platform for embedded reverse engineering. By analyzing the binary structure and hardware interfaces, we identified measurement bugs and performance bottlenecks, and provided fixes. Future work includes porting a real-time operating system (FreeRTOS) to improve UI responsiveness and adding support for external trigger input via a hardware mod. Many modern USB cables are only wired for
