Default Installation: HD2 stops at GSM connection

I have tried differents androids ROMs and all of them stucks the system at the GSM connection.

After the installation of the ROM with no problem at all, in the first boot of the installed ROM, while the initial configuration (selection of the languaje screen or Gmail Count selection screen) the system stops. Just when the icon of the GSM connection (up right) starts.

As it seems to be a radio problem I have tried differents ROM radios.

With WindowsPhone ROM, the system works without problem at all! (Just the Activation Codes... Thanks Microsoft!!!!)

May someone help me?

Thanls in advance!!!!
