Double-click the .exe file. A command prompt window will typically appear with the message "Connecting to Bootrom".

Completely close all BlackBerry software (Desktop Manager or Link) on your computer.

This often happens if drivers are missing or if another BlackBerry process is running in the background. Try running the .exe as an Administrator .

Using an autoloader is a powerful but risky process. Failure to follow steps accurately can result in a permanently "bricked" phone (a non-functional device with a blinking red LED).

It wipes all user data and reinstalls the system files from scratch, similar to formatting a computer's hard drive to reinstall Windows.

A solid green LED during the process is normal and indicates that the firmware is currently being written to the device.

An autoloader is a standalone executable file ( .exe ) that contains the entire factory-fresh OS for a specific BlackBerry model. When run, it bypasses standard desktop software to "force" the installation of the firmware directly onto the device's hardware.
