1. A method of wireless remote recovery for a wireless device, the method comprising steps of:

  • detecting a potentially unrecoverable programming error during execution of a primary program by either a programmable controller controlling operations of the wireless device or manual intervention;

    responsive to the detected programming error, changing execution of programming by the programmable controller, from execution of the primary program over to execution of a backup program;

    under control of the backup program, initiating communication with a recovery server, over the air through a wireless network serving the wireless device;

    receiving programming from the recovery server via the communication through the wireless network, the received programming including a replacement version for at least a portion of the primary program;

    correcting the primary program in storage in the wireless device by replacing the portion of the primary program with the received replacement version, to correct the programming error; and

    resuming normal operation of the wireless device by resuming execution by the programmable controller using the corrected primary program from storage in the wireless device.
