repair w200 erroneously unlocked with ******

I had a SE W200, it was working fine with its original card until I tried to unlock it with s3king, it failed to unlock the phone, but reported the phone was unlocked sucessfully, I tried to unlock it several times with the same result.
Now, the phone doesnt accepts ANY sim card, and there is no left aattempt to introduce a correct NCK code.
I need to repair this, is there any way to repair GDFS on these phones or something?
I have universal box, but am afraid to use the remote server unlock method, because it is the same s3king uses, this wuld lead me to lose credits and money again...

The Java unlocking method would also not work because I cant put the accepted card into the phone, it refuses all the sim cards..

any suggestion otehr than keeping the phone in the baggage ?

then you can have files to flash you phone in top sony download section for flashing, just read tutorial about how to flash you will get success if you follow tutorials. good day.

I know perfectly how to flash, I can use UniversalBOx, Setool2lite, XS++, I have flashed the phone many times, but flashing (obviously) will not saolve this problem, cana you please read the post again ?

GDFS repair support with SETool box. You can work it with SETool box to determine your problem.

iam not sure if its possible to tell you the truth, because the phone is meant to be dead if theres NCK reaches 0, but some say its possible to reset it. but what i know i saw a friends phone that messed around with the NCK codes and once it reached 0, he cant get it to unlock even he paid the unlocking shop.

but as what willin said try repair the GDFS using SEtool, not XS++ for some reason SEtool works better but XS++ is easier.
