Official support has even advised some users with newer versions (like V4) not to upgrade because compatible files may not be publicly listed on the site. The Risks and Rewards of Firmware Updates
Updating firmware on a precision tool like the HDS2102S is a balancing act between fixing known bugs and risking device instability.
Fixed Issues: Significant display discrepancies, such as graticules being incorrectly spaced at the 2ns/div horizontal range, were successfully resolved in versions like V1.5.1.
New Features: Recent updates (e.g., to V4.7.1) have reportedly fixed 2-channel trigger bugs and added RMS measurement capabilities.
Potential Hazards: Applying an incompatible version can lead to severe issues, such as the LCD screen displaying upside down or even "bricking" the unit if the hardware flash chip (e.g., Gigadevice vs. Macronix) does not match the update's requirements. Standard Update Procedure
If you have confirmed that a compatible update is available for your specific version:
Preparation: Download the correct firmware from the OWON website.
MSC Mode: Connect the scope to your PC via USB and set the USB mode to "MSC" (Mass Storage Class) in the system menu.
File Transfer: Copy the update file (typically named Scope.upp) to the root of the removable drive that appears on your computer.
Flashing: Restart the device. The scope should detect the file and begin the upgrade automatically before turning off.
For further community support and archived versions for older hardware, users often refer to resources like the EEVblog Forum or the OWON GitHub Archive.
