If you're a Priv owner on AT&T who has been struck with the 'No Service' bug that has been affecting some AT&T Privs since mid-September, the fix is now in. Although it never came as part of the November update package, the fix is all rather easy to install. Read on to learn how to fix the 'No Service' bug on the AT&T BlackBerry Priv.

Install the BlackBerry "No Service" Prevention Tool.

To install the BlackBerry "No Service" Prevention Tool, complete the following;

1). Enable the installation from Unknown Sources. To enable this, complete the following;

  • Navigate to the Settings > Security on the PRIV
  • Under Device administration, enable Unknown Sources
  • Tap OK when presented with the warning message

2). From Chrome on your PRIV, click here​

  • Should the message "Chrome needs storage access to download files", select UPDATE PERMISSIONS
  • Tap ALLOW

3). Tap OK when the message "This type of file can harm your device. Do you want to keep LteCaBugfix.apk anyway?" appears at the bottom of the screen

​​​Please note: Lookout Security & Antivirus may block the direct opening of the downloaded application

4). Once downloaded, select the LteCaBugfix.apk file from the Notification shade. Alternatively, tap the Downloads icon from the App Drawer

5). Select LteCaBugfix.apk

6).Tap INSTALL

7). Tap OPEN

8). From within the BlackBerry "No Service" Prevention Tool, select the Check Box for "I accept BlackBerry Solution License Agreement."

9). Tap Enable "No Service" Prevention.

10). Once the message The tool has been enabled successfully is displayed, tap UNINSTALL to remove the BlackBerry "No Service" Prevention Tool as the fix has been applied.

11). Disable the installation from Unknown Sources. To disable this, complete the following;

  • Navigate to the Settings > Security on the PRIV
  • Under Device administration, disable Unknown Sources

Please Note:

  • This is intended for AT&T PRIV smartphones running on the AT&T network only
  • This application addresses "No Service" issues related to Issue ID JI 1603353
  • AT&T PRIV smartphones running external beta release software version AAH505 contains a fix for Issue ID JI 1603353
