were your ems/adhars powered up when you upgraded? You'll need them powered and connected when you do. Also, if you have more than one screen, you'll need to upgrade each screen.
I found that with my system powered up (3 SV screens, GPS, 2 ADHARS, and EMS) when I upgraded the first screen, the EMS/ADHARS had big red X through them upon startup of the first screen after upgrade. All three screens showed the same "X". Once I completed upgrading the 2nd and 3rd screens the EMS and ADHARS came back.
My "theory" is that the first screen upgraded the software on the EMS/ADHARS, but they were still "communicating" with the old screens. They couldn't communicate because of the difference in software. Once all were on the same version, everything worked fine.
