Hi guys I wonder if you can help me? I've a s7 G390F which needs a imei repair. Can I use real term 2.0 & Odin to fix this "issue" I'm over in the U.K. & the "secret" codes to enter the imei & repair issues for whatever reason don't work? I've heard that certain carriers disable/remove this function, is this true & what can I do to get the phone working?
Thanks in advance,
Regards,
Rob.

What you heard is true. You need to unlock the bootloader to make these codes work. Further you can find s7 codes here; http://www.samsungsfour.com/tutorials/all-secret-codes-of-samsung-galaxy-s7-and-galaxy-s7-edge.html
