Problem:
I have downloaded foxflash software but it cannot get it started. Software not open and gives 2 errors.
Error 1: Fetech data: invalid JSON primitive.
Error 2: There is an error in XML document.
Solution:
Network issue.
Change a stable network connection. It should be fine.
FYI: If you get blue screen or the application failed to start problems, change a Win10 64bit system.
