Abstract: Aspects of the subject technology relate to executing a boot sequence from a recovery image. A determination of a validity of one or more keyblocks is made. A determination of a first version identifier and a second version identifier is made. A comparison of the first version identifier and the second version identifier is performed. A boot sequence from a recovery image is executed based on the comparison.

Abstract: A charging device may include a computer plug, outlet plug, AC-to-DC converter, controller, and memory. The computer plug may provide power to a computing device and receive data from the computing device. The outlet plug may receive alternating current (AC) power from an electrical outlet. The AC-to-DC converter may convert the AC power into direct current (DC) power and provide the DC power to the computing device via the computer plug. The controller may control a voltage and/or current of the DC power based on data received from the computing device and instructions stored in a memory. The memory may include read-only instructions for the controller to modify a read-write portion of the memory based on data received from the computing device via the computer plug, and read-write instructions for the controller to set the voltage of the DC power based on the data received from the computing device.
