VVDI MB BGA TOOL V2.1.7 Unlock NEC issue and finally solved

Question:
First time today it took much longer than 8 hours to Unlock NEC.
Now I cannot personalize this ESL back because it is just not calculating key password. I have working key but it keeps failing to Calculate password. I have done about 6 or 7 times already.
Is there some problem in VVDI MB BGA Tool V2.1.7? Or is the server having issues?

All sorted out. All done by VVDI Mercedes but it took so many times to calculate password. Had to do acquisition maybe 8 times or so. The NEC is also unlocked. Then wrote ESL and personalized and ll is working fine. Customer will take it over the weekend to fit as the car is more than 500km away.

If they can see why recently is the VVDI MB suffering with password calculation on W204.

 

Solved: about 8 times online calculation,the point is data acquisition,each time if acquisition without valid data means need one more time again.
