If the device boots to a battery icon but refuses to load the OS, the issue may be power-related. Aged lithium-ion batteries often suffer from voltage sag. The KeyOne requires a specific voltage threshold to boot; if the battery is weak, it may show a charging icon but never actually accumulate enough charge to trigger the bootloader. In this scenario, leaving the device to charge for a minimum of two hours on a high-amperage (2A+) charger is essential. If the battery is removable (which it is not on the KeyOne), this would be the point of battery replacement; for the KeyOne, a failure here indicates a potential hardware repair is needed. fastboot continue
