Here i would like to share a problem on FGTECH that feedback from most of customers: the tool can't work normally like it was after been used few times . it cant work with edc15, EDC16, ME7.5 and ME7.4 any more.
Don't be worry if this problem happened to you, it is very easy to solve. Just need you to fix the USD program with USB fix.
Here is a file" FG fix tool", hope it can hlp you.
