BlackBerry® Curve™

[mpavitt]

My Curve 8520 had been working fine for quite some time and then suddenly  no signal from anywhere.  I rebooted the phone and I get Device Error: 407.  It's not recognized by the charger or the desktop via USB.  Any ideas on what to do?  Desktop software says I have latest OS.

Hi mpavitt,

Reload your OS.

How to perform a clean reload of the BlackBerry Device Software for Windows

Hope it helps.

Good luck!

Reloading OS isn't working as described.

BlackBerry Desktop Software 6.0 to 7.0

1. Connect the BlackBerry smartphone to the computer and launch the BlackBerry Desktop Software.
2. Click the Device menu and select Update...
3. A dialog box appears and indicates that there are no BlackBerry Device Software updates available. Click View other versions in the lower left corner.
4. The check box for the currently installed version is selected in the Available Versions list. Click the Install button.
5. Clear the check box next to Back up device data.
6. Click the Install update button.

Although I have Desktop 7 software, there is no Update in the Device menu.  I get a dialog box that says desktop software can't connect to device.  I click Update.. but just get a message that software is up to date, no other options.  No options to do an OS install.
