[MDA II, XDA II, 2060 ROM Development] finalzero:
Here is what I modified to get the O2 Provider:

I used the Msyteryman files as a base and then using er2003Edit I opened up the ExtendedROM provided by Sin:

I clicked on the Splash Screen tab and saved the two bitmaps to my PC.

Then I extracted the CAB files from Sin's ExtendedROM and saved these to my PC.

I then closed Sin's ExtendedROM and opened up the Mysterman ExtendedROM (contains 5 CAB files). I replaced the Bitmaps with the ones from Sin's ExtendedROM and then I added the following CAB files which I had taken from Sin's ExtendedROM:

Set Button Lock

WLAN Tools 1.08

Blackberry 1.2.4.19

ExtROM Tools 1.0

Album 2.5

Video MMS 2.1

Truefax2 2.08

RegEdit 0.7

RotateSE 1.0.07

ClearType Tuner

IntelliDialer 1.0

MIDI Ringtone 5.6

MMS Composer 1.6.0.8

UltraProfiler 1.5

O2 Customisations 1.0

MS Reader 2.3

These are the files I had in the Mysterman rom (I have indicated the ones I removed):

CallerIDB10_Hima25_WWE.CAB

CameraB10_Hima25_WWE.CAB

ClearVue3.4.381WWE_0616_Ozonup.sa.CAB

MMS15024_WWE_Hima_OzUp.sa.CAB *REMOVED*

Version_OU.sa.CAB

Then I extracted the config.txt from the Mysterman ExtendedROM and edited the file to include all of the above (I removed the TPEnable.exe/TPDisable.exe lines).

The two files that perform the O2 setup are O2_Customisations_1.0.cab and Version_OU.sa.CAB. I could have used the other O2 stuff from the 1.72.00WWE WM2003 rom however I did not want the O2 Active stuff as it just annoyed me.

To use your current operators stuff you first need to get a hold of the rom image for your Himalya and you can do this by either extracting the relevant roms from your phone (search the xda-developers.com Wiki for the tools) or download the upgrade rom image provided by your operator (in my case, I had the 1.72.00WWE from O2 UK). To get the files start the upgrade program and then wait until it prompts you to hit next, then find your temp files folder (to find out where you temp folder is right click my computer, select properties and then click on the advanced tab and then click the environment variables button. The top box should show you where your temp folders are - applies to Wndows 2000/XP) - in this folder you should see similar to pft14.tmp, browse this folder and you will find all of the upgrade files in here (setup, ms_.nbf etc). Copy these files to another folder and then cancel the setup.

Open the ms_.nbf file found in the WM2003 upgrade rom image provided by your operator and then go to the splash screen tab and save the bitmap files. You can now take these bitmap files and add them to the WM2003SE ms_.nbf ExtendedROM image which will mean when your WM2003SE upgrade boots up it will show your operators splash screens.

Next you need to find the right WM2003SE customization files for your operator and you will need to search through this forum for those. Sin's ExtendedROM covers most australian networks and I think there is also an asian 2.20 rom that has the relevant stuff for asian operators - locate the correct files and inject them into the WM2003SE rom image (assuming you are using the one I provided above) and then finally you need to edit the config.txt file (drag and drop to your desktop and then open it in Notepad) and include/exclude any CAB files as required and then save and inject back into the ExtendedROM and save.

One complete just run the upgrade program and sit back and wait until its finished - as I stated the ExtendedROM might not get installed, in this case copy those CAB files to your device and then install each CAB file one by one until complete, ignore any messages about compatibility and then do a soft reset.

Good Luck,

Godz
