If you have attempted the SD card rescue (Part 2) and the USB DFU rescue (Part 3), yet the device still only shows a dim backlight, the SPI flash memory chip (Winbond W25Q64) may have physically failed. OWON uses a consumer-grade flash chip that can die after about 10,000 write cycles. One corrupted update can fry the first sector.
Given the firmware challenges, the electronics community has developed alternative software solutions for the HDS2102S that can fix some limitations without touching the device's core firmware.
