If your update fails midway, or if your device refuses to turn on after a flash, use the following troubleshooting workflows to fix the problem. Fix 1: The "Device Not Found" Error
OWON released to resolve this specific horizontal spacing issue. Users who have updated to this version or later report that the
What is the or behavior your device is showing?
Turn off the oscilloscope, then turn it on again. The device will automatically enter the upgrade mode, displaying progress, and will turn off automatically upon completion.
For the technically adventurous, the open-source project owowon on GitHub provides an alternative interface for the HDS2102S. Created by reverse-engineering the USB protocol, it allows for much faster data acquisition and control from a Windows PC. While not a tool for fixing a bricked device, it demonstrates a deep understanding of the device's communication, which could be a foundation for more advanced recovery methods. The project was tested with firmware version 1.5.1 but may work with others.
The is not a mystery—it is a methodical process of correct USB preparation, entering bootloader recovery, and forcing a clean flash. In 90% of cases, the failure is not a hardware brick but a simple USB compatibility issue or a corrupted file system.
Plug the device into the PC without the batteries installed while holding down the power button.
Connect the scope to your PC via USB. It will appear as a removable drive. Copy the Scope.upp file directly to the root of this drive.
