Configuration error after running d-unlocker

After i run D-unlocker, my phone display "Configuration error. Please contact your service provider."
D-unlocker seems unlocking the phone successfully. And my "sim lock" status is now unlocked when I press >*<<*<*
The error that i have now is same as an incorrect custom-pack.
Can i flash the phone with main, FS, and custom pack now? Will flashing lock the phone again?

Thanks for you help

you have to add customization, that`s all.

You can add the CDA or custom pack according to your firmware with a setool box or simply flash it with Main + FS with D-Client.

It will not become locked because D-Unlocker performs a permanent unlock.
