how do you downgrade from OS6 to OS5?

What are the steps to downgrade the OS? I need to install a dictation app that doesn't work so well on OS6.

 

Thanks!

Good day


Welcome to BB forums 

 

See the link below for the download, and follow these simple installation instructions.

First locate your carrier and the OS5 file you wish to use.
http://na.blackberry.com/eng/support/downloads/download_sites.jsp

Do a backup of your device first, using Desktop Manager > Backup. Close Desktop Manager upon completion.

1. Download the OS file to the PC then install it to the PC by running (double clicking) the file you downloaded.
2. Go to c:\program files\common files\research in motion\apploader and delete the file named "vendor.xml."
3. Plug in BB and double click on "Loader.exe." It's located in the same place as the above vendor.xml file.

Re: how do you downgrade from OS6 to OS5?

Thanks Rob. Is there a way to find out what the equivalent version of the software is between a Verizon device 9630 and an AT&T 9700. I would like to get the AT&T version that is equivalent to Verizon's 5.0.0.732 (platform 4.2.0.334)

 

Thanks,

Dan
