Why would you want to do that? Are you having some issues with 7.8 that we may be able to help you with?

Zune gives the option to roll back after some updates but I do not know if major updates can be rolled-back. Connect your phone to zune and have a look.

Can't rollback with Zune and should elicit message in this resource:http://support.microsoft.com/kb/2717354

 

That said warranty considerations apart, Windows Phone OS is not like Symbian device with inability to downgrade software and technically any Lumia device can be flashed with any available software version.

Happy to have helped forum with a Support Ratio = 42.5

Sound like you only partially updated. That aside by your own admission you used an unofficial way of updatingthe phone which basically means you invalidated your warranty and it might also prevent your phone from receiving the remaining updates.

At this point your best bet would be to have a Nokia Care Point flash the device for you. This will erase all personal content so make sure you have it backed up.
