Software upgrade and disaster recovery on a computing device

Abstract:

A method, a device, and a non-transitory storage medium provide to execute a first stage boot loader during a boot-up of the device; determine whether a disaster recovery service is invoked based on the first stage boot loader reading a first file that indicates whether the disaster recovery service was invoked during a previous cycle of the device and detecting a position of a button of the device; execute a second stage boot loader in response to a determination that the disaster recovery service is invoked; again determine whether the disaster recovery service is invoked; and reboot in response to a determination that the disaster recovery service is not invoked.
