Newbie w810i patching

[LEGFAN]

Hi guys, got a new black w810i, trying to unlock using tutorials on here, the problem i have is when using setool 1.11 it does'nt seem to find my phone! I follow the instructions but when i press write script, press c button and connect usb cable, the progress bar along bottom just keeps going (2 hours this morning) and nothing happens! where am i going wrong? Not sure if it's cid 49 or 50 (how do you tell?) Thanks. P.S should sim card be in or out during this operation (have tried both ways without success)
