I bought an S7 Edge that dont get signal. it have imei and sn but it cant get signal. Now i asked someone and say me that is the nv that is corrupted. The phone works and imei is clean not blacklisted. like i say is only the problem with signal. Can it be fixed if i buy a z3x box and samsung tool pro 25.6 license? here are some screenshots from service menu and settings. the strange thing is on back cover is writet an other imei and sn. i dont know if efs is broken or mainboard is changed.
I cant post the pictures because i dont have 10 posts
