Today I attempted to upgrade my V4.02.249GF4 TLT-2H to the V4.02.250GF4 version and same problem, the update tool still on START but no upgrade ...
Can you help ?

I found the solution :
In fact TLT-2H must not be powered when clicking on the START button , it's only when +12V is powered or battery connected that the upgrade starts !
Then I successfully upgraded my TLT-2H
