This is generally when a device gets hard-bricked. So, when an Android device cannot boot/enter these modes, flashing the firmware via the corresponding flash tool isn’t possible. For example, the Odin Flash Tool for Samsung devices, Xiaomi Mi Flash Tool for Xiaomi, Redmi, and Poco devices, and so on.īut these tools only work if they can properly communicate with the device over a specific mode/interface, like Fastboot Mode, Download Mode, etc. However, some OEMs also deploy their own proprietary software for flashing firmware files, which are specific to their own devices. Generally, manually flashing the firmware on a majority of OEM Android devices is carried through Fastboot (The official Android command-line tool).
