Sir, first, please downlaod the firmware on our website: http://hantek.com/en/ProductDetail_1_18.html
Copy it into the USB stick. Insert into your scope and click "Utility->Update" to update the firmware.
Before update, ensure the format of the USB stick is FAT32.
The situation in Figure 2 appears, that may be the firmware file corrupted.,
Please download and copy again.
Make sure the file copy is completed and then unplug the USB stick.
