Step 4: Click "Start Flashing", then click "Yes" to proceed with the firmware download and update, as shown in Figures 6 and 7.

Step 5: After the update is complete, click "Connect" again. Verify that the firmware name has been updated to "FT85BS", as shown in Figure 8.

Then the anomalous firmware has been updated and restored to normal.
