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.
And voilà
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?

Jeremy,

I have got a I780 dutch, so in theory I could backup my hole rom, and if you would need it, send me a PM (with instructions howto extract the complete more)
I think the (latest) phone (rom) is to have to GPS working correctly, furthermore My I780XKHA3 (pda and phone part) works with GPS out of the box, using GoogleMaps... and a more up to date phone rom should have tomtom working without using applications such as portsplitter

Furthermore; what is the latest phone rom, because I cant seem to find any clear post where al the roms are posted.

i780 does not connect 3G!!!

I have updated a fully working italian i780 to 6.1 following the instructions (russian rom...). I have the 6.1 working but the i780 does not connect anymore to 3G!
I followed also The Solutor instructions reloading the Radio section (now is IHA7 with PDA XHE1) but still it connect to gsm I TIM (gsm) instead of I TIM (3G)

Any advice on how to solve it? It is getting me crazy....
thanks

i780 Freeze at samsung logo after flashing

Hi everybody,

My brother's i780 (orange from UK, he got it with Polish ROM) had problems with wifi and gps. After trying to fight with portsplitters, patches for GPS (with no luck) i decided to flash it. I did it many times with all my PDAs, but this time I failed. First I tried to flash to Russian ROM, than to DXHE1 and then to wm6.1. After these steps Samsung behaves like this - i remove the batt, push the power button, the screen is blank for about 15 sec, samsung lolo appears and it's frozen forever (waited 15 minutes or so). It freezes when I perform a hard reset (formatting memory....).
I've tried Russian ROM alone, Italian (from parts), Polish (unbranded, Orange...) all the time the same results. Lucky me, that the bootloader works and I can still try other ROMs, but I came out of ideas. What can be wrong? I flash the PDA from XP SP2 (tried 2 different machines), installed i780 modem drivers, disabled USB connection in Active Sync - I did everything with the manual from XDA-developers forum.
I've found 2 cases like mine, but without any answer, so I'm asking you again.

Any ideas? I'll appreciate any help from you guys.

I am sorry I still have problem for updating _phone.bin. So, I have more specific questions to have this work as you did.

1. no actually switch the phone off...
Does this mean that the phone is turned off by pressing the power button when Window mobiles is on or the phone is turned off by taking out the battery and put it back on.

2. select the phone part of the rom and then connect the phone
Before the connection to i780, did you click the Detect button in MIRAGE v1.8?

3. it should auto start flashing
Neither of the cases in 1 starts flashing i780.

Any help, please? Thanks.

Hi Guys,

I tried several time to flash my i780, with no luck

I can't activate anymore the "phone" using communication manager!

The problem happens when mirage try to donwload phone.bin. I get that message:

I'm using that official rom "DXHC4", downloaded here:

http://rapidshare.com/files/11342569...DXHC4.zip.html

I'm using mirage 1.8, and official modem driver:
http://www.4shared.com/file/21525397...em_driver.html

I also tried with another official samsung updater, and .exe so without using mirage, with the same problem.

I think that something it's wrong with the driver....a problem with active sync?!?

I've also tried to flash just phone.bin....but it's the same

So guys....HELP.....
