Hello,
I have done a conversion for a MMI 3GP with sim from US to EU.
Only two thing still do not work, the tmc does not operate (using an existing EU radio unit).
And the other one is the internat dataconnection is 2G.
The unit is capable of UMTS 3G so it should connect in 3G.
The simcard is a 3G tested it in a telephone.
When i go in the green menu:
/telephony/telephonyumtse3dtrig
All the values are zero.
They should be there:
E2D offset : 11
E3A offset : 8

E1E offset : 15
E1F offset : 15

When i press the set values button, the values are there until i do a reboot.
Then the values are gone and still stuck on 2G data.

Does anyone know what to do to have a 3G connection.
