I've got same error....
If you type *#1234# got no modem (CP)

I've always solved with this..... ->root->recovery-CMW>flash in recovery custom modem & custom kernel->after that you've got back (CP) and you can write SN+IMEI......and all works but...i've got this trouble after that.... the phone sometimes freezee during call...seems to be really instable...maybe is a problem of custom modem&kernel.Any solution BST Team?

Custom recovery is not an option, it should work with stock kernel and stock rom. Please Help BST!

That's right, When I fix baseband is IMEI 0049, like i said in my first post.
PLEASE explain Super IMEI to me. Is it a different IMEI to the original imei? I want the phone to have its original IMEI back.
