Device Recovery: If your device is stuck on a "BlackBerry Error" screen, a clean firmware reload is the only fix. 2. Prerequisites Before you begin, ensure you have the following:
A Windows PC: Most BlackBerry desktop tools are optimized for Windows. USB Cable: A high-quality Micro-USB cable.
BlackBerry Desktop Software: Installed on your PC to provide the necessary drivers.
The Firmware File: The specific OS 7.1 bundle for the 9790 (usually an .exe file provided by carriers).
3. Method 1: Using BlackBerry Desktop Software (Standard Update) This is the safest method for a standard version bump. Connect your BlackBerry 9790 to your computer via USB. Open BlackBerry Desktop Software.
The software will automatically check for updates. If one is available, a prompt will appear. Click Update Now.

4. Method 2: Manual Firmware Change (The "Vendor.xml" Trick)
If you want to install firmware from a different carrier (e.g., installing a Vodafone firmware on an AT&T device), follow these steps to bypass carrier restrictions.
Download and Install the desired firmware (.exe) to your PC.
Navigate to the following folder on your computer:C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
Locate a file named vendor.xml and delete it. (This allows the loader to recognize the firmware regardless of your device's original carrier). In the same folder, double-click Loader.exe. Connect your 9790 Bold. The Loader will detect the device. Select the applications and languages you wish to install. Follow the prompts to finish the installation. 5. Method 3: Using BBSAK (BlackBerry Swiss Army Knife)
For advanced users who want to "Wipe" the device clean before installing new firmware (recommended for a fresh start). Open BBSAK and connect your device.
Click Wipe Device. Your phone will eventually show "Error 507" (this is normal; it means the OS is gone).
Follow the Method 2 steps above using Loader.exe to install the new firmware onto the blank device. Important Tips

Data Backup: Firmware changes usually wipe your messages and contacts. Always sync with BlackBerry Desktop Software first.
Legacy Note: Since BlackBerry services (BBS) are largely discontinued, firmware updates will not restore BBM or native BlackBerry email hosting, but they will improve the offline stability of the phone.
By following these steps, you can keep your BlackBerry 9790 Bold running smoothly or customize its software to suit your needs.
Part 6: Custom Firmware vs. Official Firmware
In 2025, "official" BlackBerry firmware is static. However, the community has created custom builds.
2.1 Identify Your Current Firmware
Navigate to: Options > Device > About Device Versions.
- Look for "v7.1.0." The last three digits (e.g., "569" or "649") determine your build.
- Note the "Bundle version" – this identifies the carrier-specific customization.
Custom Firmware (e.g., "9790 Hybrid OS 7.2-mod")
- What it is: A combination of 9790 base and Java .cod files from the BlackBerry Q10 (BB10).
- Features: Newer fonts, improved memory management, Dark Theme support.
- Risks: No radio stack validation; you might lose cellular functionality.
- Recommendation: Only for hobbyists with a JTAG backup.
Part 4: Post-Update Configuration and Optimization
After a successful firmware change, your BlackBerry 9790 will boot to a "Setup Wizard" – but its behavior has fundamentally changed.
4.2 Restore Data Selectively
Use BlackBerry Desktop Manager to restore:
- Restore only contacts and calendar (not system settings, as older settings conflict with new firmware).
- For BIS (BlackBerry Internet Service) users: Under Host Routing Table (Options > Device > Advanced System Settings), press Menu and select "Register Now." This reconnects to RIM’s infrastructure (though BIS is mostly deprecated, some carriers still support it in 2025).
2.5 Disable Antivirus and Firewall
During installation, the BlackBerry installer writes to the Windows registry. Security software can falsely flag the radio stack update as a threat and interrupt it.
