I want to remove phone lock code of samsung GT S5603 phone lock code.At startup only it is showing phone lock code. With usb cable (nokia ca101- i dont know it works or not) it is not showing modem, but when i put in downloader mode(volume +, volume - and power same time ) it is showing modem. I am not able to put it in qualcomm mode because of startup phone lock. I am new user of z3x box. Does same nokia ca101 usb cable works in samsung s5603 or i have to modify it? How to unlock phone lock code in this conditon please reply support or respected forum members.

I got my answer here: http://forum.gsmhosting.com/vbb/showthread.php?t=912602 .If there is phone lock usb modem will not get detected on normal mode. One can use ca101 cable and flash the handset in download mode.
