Charge Your Phone

It’s highly recommended to charge your handset before unlocking the bootloader to avoid your device from shutting down occasionally while going through the process. Make sure to keep at least 50% of charge or higher for a smooth operation.

Download ADB and Fastboot Binaries

Using the ADB and Fastboot command (platform-tools), you’ll be able to boot your Android device into the bootloader mode (download mode) which will be easy for you to proceed with further steps. ADB (Android Debug Bridge) creates a connection or bridge between the device and computer to sideload files.

Whereas Fastboot is a more advanced command utility tool for Android devices that works with computers. You can download ADB and Fastboot Binaries (Platform-Tools).

Download Samsung USB Drivers

A USB Driver is a set of files that basically allows you to create a successful and strong connection between a mobile device with a computer properly using a USB data cable. It’ll be useful to transfer files between the connected devices, flash files on the handset, and more.

It’s also worth mentioning that not only mobile devices but also other external devices can use and run USB Drivers on a Windows computer. Such as mouse, keyboard, printer, external hard drives, speakers, USB flash drives, etc. You can grab Samsung USB Drivers here.
