Nokia 3330 v4.50 unlocking

[GhostFace.P]

i've got a Nokia 3330 v4.50 and it's my personal phone, I've tried readin it with rolis flasher (4.78) but it don't read it for some reason, one error it gives me is

"NHM-6 phone not put TX line low for bootstrap begin....."

and sometimes it just doesn't do anything, it used to work before, because i've made a full flash backup. Any ideas?

Also, how can i unlock this phone onto all networks?

Any help will be appreciated

You must use noktool 1.8 by rolis and mbus cable.Then you can unlock your 3330.
