I received my unlock code for LG-M322 which is on Xfinity mobile. The phone is not blacklisted yet Xfinity won't unlock it. A friend gave me this busted up phone over a year ago. I replaced the screen and battery so that a friend could use it on QLINK. QLINK says I can use the phone, yet when I place the QLINK sim in and turn it on it doesnt start up with any place to place an unlock code. Can you help me out.
