KIES does not recognize Galaxy S2

Good day,
As the title says, my kies does not recognize the phone. I connect
the phone to PC and KIES is "connecting" and after several minutes it shows a message saying "the device is not supported by KIES."
This problem appeared after I updated the ROM, put the Jelly Bean 4.1.2 Official of Poland, and was previously with the ROM Jelly Bean 4.1.2 Official Brazil.
* The only ROM that detects KIES is the Ice Cream Sandwich 4.0.2, but I do not want this (to be outdated) because I used the 4.1.2 Brazil and the KIES recognized normal.
I formatted the phone almost 10 times, put the JB Brazil and did not work, put the JB from Poland and there was also no result, only the ICS 4.0 that works.
KIES already uninstalled several times (using the REVO Uninstaller, Your Uninstaller); restart the PC; I changed USB cell door; I put the ROM 4.0.2 to try to update the KIES, but the darn says "the device is using the latest firmware" (KIES LIE).

Please if anyone can help me, because I have important backup in KIES.
