Help w600i unlocked problem

so then i have a w600i it had a white screen but then i fixed that problem. later i decided to unlock it so i did the sim lock patch generator thing. somehow after i re-connect the usb at one of the point when it said so, it wasnt detected no more. it cant start up nor be detected by setools lite anymore theres no screen lights or anything

Instead of holding the C button, try holding 2+5 together while connecting.

ok then 2+5 i shall try that
