Yes yes yes...
I found the solution!
But it works only if you will cook your ROM...
Otherwise, you can change the registry setting, but when you do a hard reset, probably, the value goes to default!
So, you have to do this:
Open a registry editor... and point to HKEY_LOCAL_MACHINE\Software\Microsoft\Welcome
There is a entry called Disable... (if not, create it)
You have to choose some of the values below and put in the entry (this values are HEXADECIMAL)
7F - disable everything except 'email setup' screen
BF - disable everything except 'password' screen
DF - disable everything except 'complete' screen and the finishing tap
EF - disable everything except 'location' screen
F7 - disable everything except 'pop-up menus' screen
FB - disable everything except 'stylus' screen
FD - disable everything except 'align' screen
FE - disable everything except tap on the first screen
FF - disable everything [displays first 'splash' screen and exits]
If you want to put it in your ROM, try to locate the .rgu inside \OEM\OEMDrivers
There is only one .rgu there... so you know what the file you have to change...
Search in the file for the registry entry...
And change the Disable value...
Like this example:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Welcome]
"Disable"=dword:000000EF
To test it, before cook...
I recommend you to test in your Omnia...
Try to change the value, and start the \Windows\Welcome.exe to see what happens!
I will cook my ROM now only asking for the time settings!
Enjoy!
