There was no way to fix it another than to install a TW rom and go through the dialer/settings. If that settings is not checked then the phone will go black as soon as a call is made.

The behaviour exhibited by the phone after the update is not right. If it was a software issue, it would have been solved by flashing a custom ROM.
I have flash a few custom ROM and non-custom ROMs onto the d2can (i747m) and none of the phones behaved the way yours does.
