Your Android device's full potential can't be accessed until the bootloader is unlocked, so that's the first thing you need to do. A bootloader is a lightweight piece of software that loads the operating system into the memory of your device.

Follow the steps below to make a backup of your contents using Dr.Fone - Phone Backup (Android):

Step 1: To begin, have Dr.Fone installed on your computer and connect your Android phone or tablet to it. The next step is to access "Backup & Restore" from the app's main menu.

Step 2: If a prompt on your Android device asks you to enable USB debugging, just hit "OK." Then, choose "Backup" to begin saving your data.

Step 3: When you choose "Backup" up top, Dr.Fone will display a menu detailing the many information and files that can be backed up.
