How to downgrade OS 5 to 4.5?
Hi! I am totally new to this forum and don't know all the Crackberry lingo but would greatly appreciate some help. I have the OS 18.104.22.1688 and it keeps turning my phone off and freezing. I would like to get back the the original OS I had before that is recommended by Bell for my Curve 8330 which is the 22.214.171.124. Can someone please tell me how to do that? I am also not able to backup my device as it doesn't seem to be compatible with this OS to my Desktop Manager. Your help is greatly appreciated, thanks!
