Help Downgrading an OS
i've just installed the latest 592 OS but i don't think it installed correctly.
How can i either revert back to a previous version or re-flash the current version?
Good morning! If you deleted the older OS from the computer, re-install it. Make sure the Vendor.xml file is deleted if it is from a different carrier. Attach the device via USB to your computer and open Desktop Manager. (I'm assuming you have DM 5.0 or 5.1). Choose "Application Loader", and then "Update Software", and the older OS will appear as an option. The process of installing the older OS from that point on will be identical to installing a new one . . .Have fun, any questions post back!
