Silly question....
I backed up my files prior to installing OS 5.0
So my question is...if i opt to "restore" will it take me back to OS 4.7? or will i have to do a clean wipe?
When you do a back up it only saves personal information and settings; contacts, messages, phone settings..etc. It doesn't back up the core operating system. So when you do a restore it only replaces those personal items on top of your OS.
