Does the ASi button say 'ASi' or is it a mountain symbol?
Sounds to me like they were trying to load 3.0 and, as has happened to many (including me) it didn't take properly...
3.0 should allow you to have either a black or white background for the home screen, the seat icon goes from two piece to a three piece icon and the ASi changes from text to a little mountain.
With 3.5 the main home screen change is the dropping of ASi from the buttons along the bottom of the screen, which is replaced with the famous 'helmet' if you have configurable dynamics, dual screen button, or just a round symbol for mute or on/off (other combinations may be available.
As a rule of thumb then:
'ASi' - Ver 2.5
'Mountain Symbol' for ASi - Ver 3.0
No ASi button at all - Ver 3.5
This thread is too long and just being repeated over and over again. What is needed is a Section in Faults and Technical locked to the forum home page with definitive ICTP version sections to include screen shots etc so this confusion is averted
