Did the downgrade from 591 to 419. not sure if i did something wrong, but i had a bunch of tiny little icons all over the screen. had no idea what was what. since i need to have my phone for work, i am now in the process of trying to revert back to 591. hopefully this works.

I have tried and tried to downgrade my os from 5.0.0.591. I finally found a link for 4.7 and dowloaded it on my computer. (when I follow the link to download the older os (the verizon link), the only option is the newest (buggy) os)


I wiped the bb and reinstalled everything...(following the directions listed on the CB article) it put 5.0.0.591 BACK on!!! When I go to control panel, there is only one device software listed and it is 4.7.

I started completely over and reinstalled the desktop manager. Before I wipe it again, I tried to make sure the desktop manager could find the older version of the OS.
When I run the application loader, it is not there. When I select "update software", it tells me there are no updates available. When I select Add/Remove appliations, there are NO os listed there.



What am I missing? This os has rendered my bb nearly unusable.
