ENTER CODE WITH OUT SPACES
Remove sim first, press #
Press * 3 times fast for (p)
Press * 4 times fast for (w)
Press * 2 times fast for (+)
Verify code before pressing the last #.
"Code error", don't try again!!
"Phone restrictions off", it's unlocked!!

 

You have 3 chances

When you have seen the message (Can Not Undo Restriction) or (Not Allowed), it means one of the following:

You entered 5 or more wrong codes into your phone. Some models only allow 3 chances.

 

Success first time with first code - thanks keelocker, you know your stuff!
