is a highly regarded 3-in-1 handheld oscilloscope, but its firmware update landscape is famously complex due to rapid hardware iterations and version-specific constraints. To successfully update your device, you must match your current firmware version to the correct update path, as installing incompatible firmware can render the device inoperable or cause display issues like inverted screens. Identifying Firmware Compatibility

Owon utilizes several distinct firmware branches based on the device's hardware revision (PCB and flash chip version). It is critical to check your current version in the System Menu before attempting an update:

V1.x.x Series: Typically found on earlier HW 1.0 boards. Updates like V1.5.1 are known to fix critical display spacing issues at fast time bases (2ns/div).

V3.x.x & V4.x.x Series: These represent different hardware generations. Users with V4 firmware should not attempt to "downgrade" to V1 or V2 versions found on some support sites, as these branches are not cross-compatible.

V8.x.x Series: Found in the newest 2024/2025 hardware revisions, which may include features like True RMS.

Hardware Note: Some early units with "Gigadevice" flash chips may have read-only OTP SecureRom, making them essentially non-upgradable. The Update Process

Once you have obtained the correct firmware file (often named Scope.upp), you can follow these standard steps:

Enter Upgrade Mode: On the oscilloscope, press the System button, navigate to the second page of the system menu, and select Upgrade. owon hds2102s firmware update

Enable USB Mass Storage: Set the USB mode to MSC (Mass Storage Class). When connected to a PC, the device should appear as a removable disk.

Transfer Firmware: Copy the .upp file directly to the root directory of the oscilloscope's removable disk.

Execute Update: Turn the device off and then back on. The oscilloscope will automatically detect the file, begin the flashing process, and shut down upon completion.

Verification: Restart the device and return to the System menu to confirm the version number has changed. Potential Risks and Troubleshooting

Updating test equipment carries inherent risks. Users have reported issues such as the LCD display turning upside down after installing firmware intended for a different hardware variant. If the official OWON Download Center does not list a version higher than your current one, the manufacturer generally advises against attempting an update. For persistent connection issues on Linux, you may need to manually detach kernel drivers to allow the update software to claim the USB device.
