you dont need dial 9090...just enable usb dbugging and root your phone.

1. root phone.
2. write default EFS
3. flash MODEM (Phone) part or Full Flash
4. if imei 00040***** like this it means that problem solved. just write imei and OK.
if imei null/null its hw problem. try to change Flash IC and repair boot then repair imei
