To those who were able to unlock their phone with the method above, can you please post in the thread and let us know which phone model (N7100 or N7105) you have, Country and Network/Carrier your phone was locked to... and I will update this post... and if I have saved you some cash, please click the Thanks button or the button on the left just below my name to buy me a can of Heinekken, Budweiser, Fosters, Tiger, Stella Artois, or San Miguel ...
THANK YOU for sharing this trick!
It also works with the GALAXY Rugby LTE SGH-I547C locked to Bell Mobility (Canada).
