The phone must be detected as "SAMSUNG CDMA MODEM" on device manager.
Solution:
Power on the phone with accepted sim card inside, go to settings menu and set USB connection to PC Studio mode.
Then unlock the phone.

Connect powered on phone with Sim card inside then try again.
Use NsPro RJ45 E210 cable!!!

well yes...
1- flashed the phone with the patch files complete
2- I put an accepted sim card on the phone
3-go to settings usb conections and select pc studio
4-the phone is in the device manager as "samsung modem"
5-everything is in place but when I hit unlock "operation failed"

I already tryed everything

ps: I also conected 2 phones at the same time ,just to check, one in the usb and the other one in the rj45 from the box,so in that way I have the "samsung modem" detected and and the box is showing the process ok successfull but any of those phones is unlock????

so elco please help
thanks
