Downgrading is something that has become somewhat of a necessity these days. It’s almost as common as upgrading. Why? Well, in this rapidly progressing technological world where every OEM wants to the first one to roll-out the newer Android version, things like unprepared softwares are very common. But we don’t blame them entirely, they want to win the race just like everyone else. The suffering goes to the users who trust their OEMs and upgrade their devices.
