I have the same chirping sound with the Verizon OS 4.5.0.175. How do I downgrade to the old OS?
1. Delete the newer OS from your PC by going to Control Panel >Add/Remove Programs.
2. Then download and install the older version of the OS. BlackBerry Operating System Downloads
3. Install the older OS to the PC by running (double clicking) the file you downloaded.
4. Go to c:\program files\common files\research in motion\apploader and delete the file named "vendor.xml."
5. Plug in BB and double click on "Loader.exe." It's located in the same place as the above vendor.xml file.

@mason, @455ho, it is CONFIRMED that this OS will load to the MEID devices as well as ESN devices.
In the past, separate OS files were needed for each, apparently this one covers both.

As always, do a complete backup first using Desktop Manager.
