Blackberry 9860 – Network Inactive

It’s a Blackberry 9860, and had a Red Blink problem.

I used this foro and repair it using this two treads (thanks):

NUKE, WIPE, NAL and OS all in one script
and
Repair RED BLINK , EFS CORRUPT on QUALCOM , BB OS 7.0 n 7.1

After following the steps, the phone lit properly, but does not connect with the Mobile Network. Connect with other telephone companies in SOS, but not with the corresponding. At one point the phone connected, but for a few minutes.

I contacted my telephone company and was told that the IMEI is correct (not locked), and the phone is associated with my line. They ask me to manually change the network, but my phone does not have that option.

Technical data of the phone:

BB: 9860
OS: 7.1.0.714
SIM: Disable
Network: Inactive
Networ Subset: Disable
Service Provider: Disable
Corporate: Disable

Someone can help me?
Thanks,
