I have a lg shine cu720 and its asking for a security code i dont know it. it is a at&t phone i have tried 0000 and 1111 and 1234 nothing works please help me.
If you bought the phone new and the default 12345 does not work, then
the security code should be in the papers you received with the phone or
maybe printed on the box.
If you bought it second hand then the previous owner should be able to help you.
you'll have to take the phone to your nearest service provider with
proof that you are its owner (invoice in your name with the phone's IMEI
number, and photo ID) and they'll be able to reset the security code
for you. Do a backup before having this done because it might entail a
full reset of the phone, which will erase all your data.
you could attempt a firmware update with LG Software Updater. A
firmware update often resets the security code back to the factory
default (but not on all models).
