To fix the gps you need to download the whole DXHC4 rom.
Extract it in a folder
Open Mirage program, click on eboot+pda+phone button
Select DXHC4 file, kill the mirage program in the process of the task manager.
Look into you c:\ you must have _phone.bin file, it's the file you will flash it contain the radio that fixs tomtom.
Open mirage loder click on phone button and select the _phone file.
Press detect and plug your phone.
Flashing radio don't get loose langage.
I'm confused now.
So you are saying that it takes ONLY the _phone.bin phone part of DXHC4 to have the GPS working without helper software?
Others are saying that the phone part isn't relevant and you need the PDA part and the phone part.
What is it now?
