If you've landed on this review, you might not need anyone to tell you what flashing a phone is all about. But just in case you don't know, we'll inform you that it's basically a reinstallation of the operating system. In Android, it's used when we want to install a modified version of our operating system.
An app to flash Android
If you've reached the conclusion that you need to flash your device, then FlashFire Root is the app that you need to download. However, you need to remember to root your smartphone or tablet beforehand because this application requires superuser permission to work correctly.
This app can flash a device via OTA (over the air) or by means of updates in ZIP format. For such purpose, it comes along with all compatible backup and restoration functions, as well as different input methods such as SD cards, USB connections or even streaming through WiFi networks.
But as you already know, if you download the APK of this app that replaces the legendary Mobile ODIN, you have to use it very carefully because it could leave your phone totally useless and turn it into a very expensive brick.
