If you are considering buying a new phone, you might consider the Galaxy A8 and Galaxy A8 Plus 2018. Owning a smartphone means you are supposed to know everything about its software and hardware as well. When it comes to software, we often need to install new software in order to upgrade the phone, restore it to factory settings or simple to fix the existing issues on the phone. Fortunately, Samsung makes it extremely easy for its loyal customers to install the software on the phone. It’s incredibly easy to restore your Galaxy A8 or the A8+ 2018 to its factory state.

Why you should install a Stock ROM?

Installation of a stock ROM on your phone refreshes everything. It wipes off any previous data stored on your phone. If your phone was previously rooted, installing a stock ROM will unroot it. In case there’s a new version of Android available for your phone, and you just cannot get it because the update is available in another country, you can always download the entire update and flash it manually. Before flashing stock firmware on your new A8/A8+, keep in mind that it will not restore the warranty of your phone if it was void. However, the installation will not void the warranty either if it was intact.

The installation happens through Samsung’s own software called Odin. There’s a great misconception that Odin will damage the device or it’s not a trustworthy tool. I would like to tell you that Odin is Samsung’s official tool and it’s safe by all the means. Using Odin will not damage your phone in any way. You can proceed with the firmware installation without any fears.
