Abstract: Embodiments of the inventive concept include computer-implemented method for shadowing one or more boot images of a mobile device. The technique can include duplicating boot images to shadow partitions in a user area of a non-volatile memory device such as a flash memory. The technique can include detecting boot image corruption, and causing a mobile device to boot from the shadow partitions. The technique can include dynamically shadowing and releasing blocks used by the shadow partitions. The technique can include boot failure recovery and bad image preservation through firmware flash translation layer (FTL) logical to physical mapping updates. Boot image corruption failures can be recovered from and/or debugged using the shadow partitions.
