I've been trying to downgrade from 4.5 to 4.3 all day today with no luck. I've read the easy to follow steps but ALL the links I've found says I can find the BB OS 4.3 here... https://www.blackberry.com/Downloads...E4F82F9F00E7D4
That just let's me download Desktop Manager Version 4.3. Where do I download the Device Software???
I have downloaded the 4.3 Desktop Manager and plugged my BB Curve 8310 thinking it would auto download the device's version but it didn't. I clicked on the Application Loader but nothing happened.
I even went and deleted the vendor and still nothing.
I want to downgrade cause after I upgraded to 4.5, the ringtones on my device weren't nearly as loud as with the previous version I had on my phone.
Someone please help
