Always back up your data before proceeding. Incorrectly performed updates can lead to loss of functionality, though permanent hardware damage is considered rare. Also, the oscilloscope's USB interface is a single logical interface shared across two physical ports, so you cannot use both simultaneously.

Performing a firmware update on the DSOTC2 requires careful preparation and adherence to the correct procedure. Always source firmware from the official manufacturer, ensure stable power, and verify the update afterward. If the device is mission‑critical, test the new firmware on a spare unit first.
A successful firmware update can fix all of the above. Conversely, an incorrect or interrupted update can turn your DSOTC2 into a paperweight. Hence, reading this entire guide before proceeding is paramount. Always back up your data before proceeding
You can only upgrade one firmware type (CH or MM) per session. To update both, you must repeat the power-on sequence for each mode.
The is one of the most popular budget 2-in-1 handheld devices for makers, combining a digital oscilloscope and an LCR transistor tester into a single portable unit. However, factory-loaded early firmware versions are known for minor bugs, system freezes, lagging component detection, and sweep or synchronization issues during high-frequency measurements.
You may find community-made firmware (like those on GitHub or EEVblog) intended for similar-looking transistor testers. Avoid flashing these to a DSO-TC2
