Re: How to Downgrade from OS 7.1 to OS 7 for 9380 Curve

Hello,

 

The simplest way is to, on a PC (you cannot do this on MAC):

 

1) Uninstall, from your PC, any BB OS packages

 

2) Make sure you have the BB Desktop Software already installed

 

3) Download and install, to your PC, the BB OS package you desire:

 

4) If that OS package is from a carrier other than the carrier for which your BB was originally manufactured, then delete, on your PC, all copies of VENDOR.XML (there will be at least one, perhaps 2)

 

5) Launch the Desktop Software and connect your BB...the software should offer you the OS package you installed to your PC

 

Don't forget to backup.


If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:

Good luck and let us know!
