I recently upgraded from 4.3 to 4.5 for the Pearl 8120, but it's running very slowly, and the thing I upgraded for (rtsp streaming) isn't working. The instructions I've found for downgrading include going to my carrier's website (T-Mobile USA) and getting an older OS, but T-Mobile only has the latest OS available. Is there somewhere I can get older versions?
I'd also be willing to re-flash my Berry with 4.5 and see if it just "did it wrong" the first time, but I don't know how to do that, either.
yeah, i just checked blackberry.com and couldnt find it, and i tryed googling it and couldnt find it.. im sure someone will come along with a link for ya..
Try connecting your device to DM and going to the update software section of the app loader. This screen might still show the 4.3 OS as a downgrade option if you recently did the update. Because when I go to do any update on my storm, it shows the OS the device was released with (labeled downgrade), the current official (labeled recommended) and whatever leaked beta OS as options to install.
