3. Battery Meter Fix: Pre-2023 firmware had inaccurate battery percentage reporting. Verified updates fix the voltage curve.
4. SPI Decoding: Enhanced trigger stability for serial decoding.

Troubleshooting "Unverified" Behaviors

Even with a verified file, things can go wrong. Here is the technician's recovery guide:

Issue: "DFU Tool hangs at 50% (Writing)." Solution: Your USB cable is likely a "charge-only" cable. You need a data sync cable. Swap the cable and restart the process. The HDS2102S is picky about handshaking.

Issue: "After update, the Multimeter reads 0.000V constantly." Solution: The firmware update reset your internal calibration EEPROM. You need to run a "Self Cal." Put the scope in a stable 25°C room. Disconnect all probes. Go to Utility -> Self Cal and let it run for 10 minutes.

Issue: "Version number didn't change." Solution: You loaded the wrong file. The HDS2102S (100MHz) uses a different FPGA bitstream than the HDS2072S (70MHz). Download the specific "HDS2102S" folder, not the generic HDS2000 family pack.

Step 4: Verification

The update takes about 90 seconds.

• Good: You will see "Erasing... Writing... Verifying... PASS"
• Bad: "File not found" (check the owon folder name) or "CRC Error" (bad download).

Once it says "PASS", power cycle the device normally.

Safety Precautions

• Backup Data: Before updating firmware, it's a good practice to backup any important data on the device, as the update process may erase data.
• Stable Power Supply: Ensure that the device has a stable power supply during the update process to prevent interruptions that could damage the device.
