The BlackBerry STL100-2 autoloader is a packaged firmware installer for certain BlackBerry 10 devices (models in the STL100 series). An autoloader contains the device OS image and a small installer that writes a complete system image to the phone, restoring it to a clean state. Autoloaders are commonly used to recover bricked devices, downgrade/upgrade the OS without using an over‑the‑air update, or prepare a device for resale.
If the device shows a blinking red pattern (such as two blinks, a pause, then repeats), the flashing process failed or was interrupted. This usually means the OS version within the autoloader does not match the hardware security version allowed by the processor's fuses (Anti-Rollback Protection). Ensure you are flashing an OS version equal to or higher than the version previously installed on the phone. Stuck on the "Connecting to Bootrom" Screen blackberry stl100-2 autoloader
