How To Fix a BlackBerry 507 Error

Generally, BlackBerry devices are known for their stability and reliability compared to other smartphones, but like any computer-like device, errors can occur. One of the more frequently experienced errors on the BlackBerry platform is the 507 error, which basically means that a part, or all of the actual OS is missing from the handset. To fix a BlackBerry with the 507 error, the operating system needs to be completely reloaded on the device, so the process won’t be instant – but it does work for most users.

Note: At this time, there is no way to re-install your OS using Mac OS. If you are a Mac user and would like to re-install your BlackBerry operating system for any reason, you’ll have to install Windows using Bootcamp, VMWare, or Parallels and complete the process from there.

Before you begin this process, make sure you have the latest version of BlackBerry Desktop Manager installed, and the latest official OS version downloaded.

Download and install Desktop Manager
Download the latest official OS

Once you have the necessary software downloaded, start by installing the BlackBerry OS to your computer. To do this, simply double-click on OS file(.exe) that you downloaded. Follow the prompts to install it to your PC.

Next, delete the Vendor.xml file. This will ensure the OS will be installed properly to your device – especially if the version was released by an alternate carrier. To find the Vendor.xml file, go to Program Files / Common Files / Research in Motion / App Loader on your computer.

Finally, it’s time to perform the OS install. The easiest way is to go back into the folder where Vendor.xml was located – Program Files / Common Files / Research In Motion / App Loader. Ensuring your BlackBerry is connected via USB, double click on the Loader.exe file, following the prompts to complete the OS installation. The full installation process can take anywhere from about 20 minutes up to a couple hours.

If your computer won’t recognize or connect to your BlackBerry device, try out the following:

Launch BlackBerry Desktop Manager. Go to Options and select Connection Options. Under Connection Type, choose USB

Pull the battery out of your BlackBerry, and connect it to your computer via USB. Within the next 30-60 seconds, go to the Application Loader in Desktop Manager and select Update Software

Choose the OS version you wish to install, and follow the prompts to install the device software. If prompted, choose NOT to automatically back-up and restore

During the installation process re-insert the battery into the device. Allow the installation to complete, which may take up to an hour or so.
