Unlocking an LG CU400 phone? I have the code but....
The instructions given by ATT do not match with the phone and LG is offering no help at all.
"Power off device and remove AT&T SIM card.
Insert SIM card from another wireless carrier.
Power on handset - phone will display "Invalid SmartChip".
In Idle screen, enter 159753#*# - this does not display on the screen.
Enter 8-digit Unlock code.
Select "OK" - the handset is successfully unlocked."
After I entered 159753#*#, it took me to a different menu with more sub menu.
Any help appreciated
