Every Android device has, what is called, a recovery image on it. This is basically a part of the Android operating system that you or the manufacturer can access if your device becomes unresponsive and then use it to restore your device.
A custom recovery image, however, is a recovery image that a developer has altered that can not only help the device if it becomes responsive, but also has the added benefits of allowing us to make major changes to the operating system and have even further customizations on your device.
In this procedure, we’ll show you how to flash a custom recovery on your AT&T Samsung Galaxy Express (SGH-I437).
After flashing a custom recovery on the Galaxy Express, you’ll be able to:
- Perform full backups of your device (literally save EVERYTHING from it).
- Increase your device’s performance (after flashing something called a kernel).
- Increase your device’s battery life.
- Flash custom ROMs (these make it possible to flash a newer version of Android, totally new user interfaces, add tons of new features, and much more).
