Abstract: Methods, systems and devices are provided for revising a data image of a read-write memory device. The method includes accessing an initial data image from an initial virtual block corresponding to an actual block of a series of actual blocks of the read-write memory device. The initial data image includes an initial boot loader. Also, a backup data image is stored in a remote virtual block spaced away and following in the series of actual blocks from the initial virtual block. The backup data image includes a backup boot loader. Additionally, the initial data image is erased from the initial virtual block and a replacement data image is stored in the initial virtual block. The initial virtual block may include more than one virtual block spaced away and proceeding in the series of actual blocks from the remote virtual block.
