If a software update is interrupted, or if an experimental custom ROM corrupts the core sboot.bin file, the device loses its map to start the operating system. The CPU continuously loops inside the BROM code trying to establish communication. This infinite loop keeps the processor core at maximum utilization without power management rules active, generating excessive heat. 2. Physical Short Circuit on the Logic Board
