Help Diagnose problem with my machine

[AstonBay]

Hi All, I have acquired an LD002H, can someone help me diagnose the problem I have.
Currently on V4.3.16, If I try upgrade4 firmware, I get "invalid file format".
The clean vat function is missing.
Calibrate shows a band across the screen and not the rectangle test.

Thanks in advance to anyone who can assist.
