Help!!! Unlocking K750i

Hi,

I seeking help on my K750i unlocking. Been looking around in forums for a week and manage to flash and patch successfully with the Simlockpatchgen using SeToollite v1.11 and my SIM lock is totally cleared. However now I have the problem that the phone cannot find any network due to Network and Network subnet lock in Personalize page. Can anyone advise me what should I do next? Is it have to use the NCK unlock code generate from IMEI to clear the lock? Anyway, my IMEI is 35967200-783647-4-14. Hope someone can supply me with the unlock code, I will be very grateful. My K750i is DB2010 and CID49 Red. Thanks in advance.
