I have a LG MS769 (LG L9) from MetroPCS. I already purchased an unlock code. I go to the hidden menu using 2945#*769# but when i click on "Network Unlock", instead of getting the box to enter my unlock code, i get a message that says "You're phone is not personalized". Pleaaase help! maybe someone knows a different way to enter my unlock code?? any info would b appreciated. thanks.
