I have a question for you concerning a Samsung Galaxy S2 T989 from TMobile. I am trying to un lock it to use it with another carrier. I used various unlocking tools, Galax unlock from the google market as we as others, but none work. To make a long story short, I can't find the nv_data.bin, nor anything in the efs folder. And the final question can this phone be unlocked minus the nv_data method? Has any one sucessfully unlocked this phone? Thank you.
