What is Bootloader Unlocking?

A bootloader is the software that loads the operating system when a device is powered on. Unlocking the bootloader on an Android device allows users to install custom software and modify the system to suit their preferences.

2. Enable Developer Options: Go to Settings > About Phone > tap Build Number seven times to activate Developer Options.
3. Ensure Full Battery: Make sure your Galaxy Z Flip 5 has at least a 70% charge to prevent interruptions during the process.
