is a delicate process because OWON generally does not publish public firmware links for this specific model . Firmware is typically tied to specific hardware/serial number revisions, and using the wrong "piece" (firmware file) can brick the device . Critical Warning

Official advice from OWON support is to not upgrade unless you are experiencing a specific bug, as there is no universal "latest" version for the Updating the firmware on your OWON HDS2102S handheld

on their website . If you proceed, ensure the firmware you use matches your hardware revision exactly . Firmware Update Steps

If you have obtained the correct .upp file from OWON Support or an authorized source, follow these steps : Prepare the Device: Turn on the and navigate to System > System > (Next Page) > Upgrade.

Connect to PC: Connect the oscilloscope to your computer using a USB-C cable.

Enable MSC Mode: In the System menu, select USB and set it to MSC (Mass Storage Class). The scope will appear as a removable disk on your computer.

Transfer the File: Copy the firmware file (typically named Scope.upp) to the root directory of the removable disk.

Reboot and Flash: Safely eject the device, turn the scope off, and then turn it back on. The device will automatically detect the file, perform the upgrade, and shut down once finished.

Verify: Turn the device on and check the System menu to confirm the version number has updated. Common Firmware Versions & Fixes

Version 1.5.1: Known to fix a specific display discrepancy where graticules were incorrectly spaced at the 2ns/div time base .

Version 2.0.4: A newer update reported by some users, though specific changelogs are often not provided by the manufacturer . Troubleshooting & Support Official Downloads: You can check the OWON Download Center for any newly released software or manuals, though specific firmware is rarely listed there.
