Patent ID: 8726259

Claim:
An electronic device comprising: a non-volatile memory comprising a back-up file, the back-up file comprising at least one phone parameter associated with a prior version of a firmware program utilized to establish communications between the electronic device and an access point, the at least one phone parameter comprising at least one variant non-volatile item having at least one variant offset stored within the back-up file within the non-volatile memory, the at least one variant offset associated with the prior version of the firmware program utilized by the electronic device; a processor communicably coupled to the non-volatile memory; a firmware over-the-air client module executed by the processor, the firmware over-the-air client module configured to receive a firmware over-the-air upgrade and replace the prior version of the firmware program utilized by the electronic device; and a back-up and restore module executed by the processor, the back-up and restore module configured to store the at least one variant non-volatile item before the firmware over-the-air client module performs the firmware over-the-air upgrade, wherein the firmware over-the-air client module is configured to reset the wireless handset after the firmware over-the-air client module performs the firmware over-the-air upgrade, wherein the reset is a power cycle of the electronic device, wherein the firmware over-the-air client requests the at least one stored variant non-volatile item during a power up of the power cycle of the electronic device; the back-up and restore module further configured to: rewrite the at least one variant non-volatile item into the firmware over-the-air upgrade after the firmware over-the-air client module resets the wireless handset, and generate a new offset for each restored variant non-volatile item.
