...to unlock phone code, you not needed to unlock your phone (of course, if your phone is not unlocked to the one network...).
Just open papuautils, click to "Service Mode, enter in “Various” and click on “Read IMEI”
Click on “5008 Phone code” and your phone is unlocked from phone lock.
If your phone is unlocked on the network, you need to unlock it. See on attachemment.
Of course, you need to use the service cable (not data cable) like serial C55 cable, serial DCA500, USB to serial DCA510 modifyed (inserted two resistors between pin2 and pins 5 and 7).
That is.
