Uninstall the leaks that are installed on your pc ..
go here: BlackBerry - BlackBerry Desktop and Device Software Download Sites
and download the AT&T one for the 9900 ..
Open up loader.exe via c:/program files/ common files/research in motion/app loader
delete the xml file and run loader.exe
plug in your device and follow the steps.
Hope that helps
Just run Desktop Manager. Go into Device > Update my device > View other versions and all the carrier released OS's should be there. Prior builds will say (downgrade)
