Abstract
An exemplary method for unlocking a wireless communications device comprises entering a backdoor screen, prompting input of a backdoor code, receiving the backdoor code, comparing the received backdoor code to a service validation code, and resetting an unlock code of the wireless communications device if the received backdoor code matches the service validation code. The service validation code may be, for example, a one time subsidy lock code, an operator master subsidy lock code, another service programming code or any other stored code not generally known to the user. The method may further comprise unlocking the wireless communications device if the received backdoor code matches the service validation code.
