Default OS Downgrade

Please Login to Remove!

I've searched and searched and searched but I can't find good instructions on how to downgrade the OS. I upgraded to the TIM version but it's just not working out and want to downgrade back to the cingular red version. Could somebody please help me out?

I think you just need to back up your bb and then run the install for the red .73 version.

Did you uninstall the TIM firmware release?

delete the vendor.xml file in the C:\Program Files\Common Files\Research In Motion\AppLoader folder and then launch DM.
