1. Introduction

Firmware updates for digital oscilloscopes deliver feature enhancements, bug fixes, and security patches. However, update failures can render devices partially or fully nonfunctional. The Owon HDS2102S (a 2-channel, 100 MHz-class mixed-signal oscilloscope) is widely used in educational and hobbyist contexts; limited documentation and varied update procedures have led users to encounter update failures and bricked units.
