Hi all

Can anyone pls let me know why i cant add vietnamese language to my 8290. Here is what i did:

1) I upgraded my phone to 8850 with the vietnamese language pack. --> Phone OK. Can display vietnamese but no network signal.
2) Then I upgraded it again to 8890 using the vietnamese language pack from 8850. -->Cant read anything, vietnamese messed up.

Is there any solution for this???
Thanx.
