BBSAK (BlackBerry Swiss Army Knife): A third-party utility often used to "wipe" the device to a clean state (Error 507) before loading new firmware.

Hardware: A high-quality micro-USB cable and a computer running Windows. 2. Step-by-Step Installation Procedure Step A: Device Preparation

Backup Data: Use BlackBerry Desktop Software to back up contacts and messages, as this process will erase all device data.

Wipe Device: Open BBSAK, connect your phone, and select Wipe. The device should eventually display "Error 507", which indicates the OS has been removed and it is ready for a fresh install. Step B: System Configuration

This is the standard procedure for applying official carrier-approved updates.

Installation: Download and install the legacy BlackBerry Desktop Software on a Windows or macOS workstation [0.5.2].

Connection: Connect the BlackBerry 9790 to the computer using a micro-USB cable.

Authentication: Ensure the device is unlocked; the software will automatically check for available firmware revisions.

Application: Select "Update" to download and push the firmware to the device. Do not disconnect the device during this phase, as it may lead to a "bricked" state. Method B: Security Wipe (Firmware Maintenance)
