Default [Q] Problem not sim detect / TA

Hello!
At the entrance I will add that I have a locked bootloader, and that I have "bootloader unlock alloved no".
Yesterday I've downloaded flash tool and it was there I began the whole story.
- I'm one Unlock the bootloader (via flash mode only), and so it's a total nothing could.
-I have flash the file simlock.ta with firmware T-mobile (simlock.ta i rename to "preset.ta" )

And now this happens:
Phone works normally, but after entering the pin code says that the code has been adopted, then the sim card is not known.
Of course, other phones working fine.

I'll tell you this: I am a developer but sim locks, and so is the case for mne strange thing.
I received from a friend that kind of partition TA was damaged hence this problem and I do not have a copy of the TA.
Any advice besides the service?
