Abstract
Disclosed techniques enable wireless remote recovery for a wireless device that has encountered a potentially unrecoverable programming error during execution of a primary program controlling operations of the wireless device, e.g. an error that might otherwise prevent network communications. In response to the error, program execution changes over from the primary program to execution of a backup program. Under control of the backup program, the wireless device initiates a communication with a recovery server, over the air through a wireless network serving the wireless device. The communication utilizing the backup program enables the wireless device to receive programming from the recovery server, including a replacement version for at least a portion of the primary program. The primary program can then be corrected by replacing the portion thereof with the received replacement version. The wireless device then resumes normal operation, by resuming execution using the corrected primary program.
