Even if the update reports success, always perform a factory reset:
The OWON HDS2102S is a popular 2-channel, 100 MHz handheld digital oscilloscope with a built-in multimeter. Like any sophisticated electronic device, its performance and stability depend heavily on its firmware. OWON periodically releases firmware updates to address bugs, improve user interface (UI) responsiveness, and add functionality.
If you are experiencing specific issues with your HDS2102S, a firmware update is often the definitive fix.
Sometimes the firmware installs successfully, but the device functions incorrectly. The most common post-update bug is the channel 1 or 2 showing a flat line even with a probe attached.
| Symptom | Likely Fix | |--------|-------------| | No "Updating" message | Reformat SD card as FAT32; try a different card (4–8 GB recommended). | | Update freezes halfway | Do not power off for 10 minutes; if still frozen, contact OWON support – manual recovery may require a JTAG or bootloader reflash. | | Device no longer powers on after update | This indicates a "brick." Try holding the power button for 15 seconds to reset. Otherwise, professional re-flashing via serial port is required. | owon hds2102s firmware update fix

If you are trying to fix a failed Owon HDS2102S firmware update, try this:
If that fails, check if you have the "N" model variant vs the standard model, as the firmware files are different and using the wrong one causes the white screen issue.
This is a comprehensive guide to fixing, updating, and troubleshooting the firmware on the Owon HDS2102S (and the wider HDS-N series). Even if the update reports success, always perform
Disclaimer: Firmware updates carry a small risk of "bricking" your device if done incorrectly. Proceed at your own risk. Do not interrupt the power during the update process.

This assumes the device is stuck, fails to boot, or shows erratic behavior after an update attempt, and provides a structured fix procedure. If that fails, check if you have the
Once you see the bootloader console:
If you see any error message like “Bad CRC” or “Partition mismatch,” your firmware file is corrupt or for the wrong model (HDS2102S vs HDS2102 – they are different!). Redownload the file from OWON directly.
This paper investigates common firmware update failures in the Owon HDS2102S digital oscilloscope, analyzes root causes, documents reproducible procedures to recover devices and successfully apply firmware updates, and provides recommendations for manufacturers and users to reduce update-related failures. We present experimental results from multiple update attempts, recovery workflows (including bootloader entry, USB-to-serial recovery, and SD card flashing), and a checklist for safe firmware maintenance.
