Blackberry Curve 8900 - OS 5.0 trying to downgrade to 4.6

Hi - I have a curve 8900, and I updated it to OS version 5.0 which I found on one of the BB forum sites. Recently, I downloaded BBM 5.0 on my device, and after installation, the messenger has disappeared from my menu. I am trying to downgrade to version 4.6, but I get a message saying No updates available. A person I know who did the same as me, however, was able to downgrade to 4.6, but I have tried doing this on 2 different computers, but it doesn't work. Please advice what I can do to rectify this. Thank You.

Sincerely,

Pinakin.

Re: Blackberry Curve 8900 - OS 5.0 trying to downgrade to 4.6

hmmm.... you're dealing with Beta software and something is not working correctly. There's a reason it's called beta.

 

Make certain that ALL previous and later versions of the OS are deleted from your PC. Leave only the version you want to install. Do not use Desktop Manager, use the loader.exe file found in the apploader folder on your hard drive.
