Recently, Obd2tool  has received  some question about Ford VCM2 firmware downgrade,and obdexpress found  the same problem in the mhhauto OBDII scan forum.   Here you are:  I just get VCM2  and instaled IDS v86 and when I start sw error I get that VCM firmware is newer then IDS sw.  How to do?  Customer solutions from the MH forum:  Press and hold reset button after that insert usb to pc still hold  reset button when you will hear beep after that release reset button.  If it does not works….  Try to use this Ford VCM II Software setup v2.1.119.3. I have Chinese  clone Ford VCM II and working with Ford IDS v86, Mazda IDS v91 and with  JLR SDD v138 with this software setup too. My VCM have no problem with  update downgrade I had installed Ford IDS v95 after that v86 and no  problem update downgrade. When I installed JLR SDD v138 I had to update  VCM to this version and after that was not functional with Ford IDS v86  after installing this setup was all functional.  Ford VCM II v2.1....
