I have a Foxwell NT530. The SN is N0530dxxxxxx. I tried to download software on my Chromebook Laptop, but the file was not incomplete. So I used an older computer to download again. As a result, the upgrade icon on the device disappeared and there was no model information. I haven't changed any language. It's always been English.
The solution offered by Foxwelltool.com engineer:
The HOME program may be broken.
Just take the TF card out, and format it. After that, put it back to the NT530 scanner, and update it again. Or use the card reader to update it directly.
