Flash most earlier C5 ultra single sim firmware. If that will not help - your phone needs to be customized in Sony factory, because Sony Service Centres does not support prototype phones. Ergo - your phone can't be fixed at all.

thank you for your reply,Jurij.
I have tried flash firmware and simlock.ta file But it didn't help..
so I think I can find a prototype C5 single SIM TA FILE,use the "000007DA" area to flash my phone,it will repair SIM LOCK issue..

No. You can't flash trim area from other phone - it will kill your phone forever. If you've damaged somehow security units, only Sony factory can fix your phone. And it will not be possible using third party tools, because 2048-bit rsa security is still unbreakable ;(
