A white text bootloader menu appears (not the normal blue waveform screen).
He’d read the release notes the week before: "Improved trigger stability on low-amplitude signals; corrected rare UART logging freeze; minor UI refresh." Those sounded like lab folklore — the sort of fixes firmware teams promise between versions — but the UART freeze had bitten his test runs twice this month. Mid-run freezes meant lost data and late nights. So Jun scheduled a brief maintenance window.
specifically, not the HDS2102 (no 'S', which often indicates no built-in waveform generator) or HDS200 series, as using the wrong file can cause malfunctions. Conclusion Updating the firmware on your Owon HDS2102S
Use the high-quality USB-C cable that came with your oscilloscope. Poor quality or data-blocking cables can cause the file transfer to corrupt.

Step 1: Preparation Jun backed up the scope’s screen captures, saved the configuration file, and removed the BNC leads from sensitive DUTs. He printed the update notes and checked the scope’s current version: 1.02. The update file on his flash drive was labeled HDS2102S_v1.04.bin, with a checksum published on the vendor page. He confirmed the MD5 hash matched. Verification first; assumptions later.

Leave the device untouched for at least 5 minutes. If it remains completely frozen, ensure your power source is secure. Do not force power off unless absolutely necessary, as this can corrupt the flash memory. Broken Waveform Display Post-Update So Jun scheduled a brief maintenance window
Manufacturers constantly refine their code. For the HDS2102S, a firmware update typically yields several immediate improvements:
The Owon HDS2102s firmware update improves trigger stability, signal generator performance, and multimeter speed, with updates best sourced from the official website.
