Owon Hds2102s Firmware Update Fix May 2026

This assumes the device is stuck, fails to boot, or shows erratic behavior after an update attempt, and provides a structured fix procedure.

• Preparation:
  1. Official Request: Email Owon support (support@owon.com.cn). They are generally responsive and will send you a Google Drive or WeTransfer link to the latest firmware.
  2. Community Repositories: The EEVblog Forum has a dedicated thread for the HDS-N/S series where users mirror the latest files.
     1. Wait for the system to say “USB device detected – update file found.”
     2. If it doesn’t auto-start, use the universal soft-key command: Press F4 (labeled “Update” or “Erase & Update”).
     3. The system will display: “Erasing NAND block 0000...” – This takes 3-5 minutes. Do not power off.
     4. After erasure, you will see “Writing firmware... Do not remove power.”
     5. When complete, the scope will say “Update successful. Reboot in 5 seconds.”
