Fastboot (or bootloader mode) is a special smartphone state in which the operating system does not boot, but commands are available to interact with the hardware.

• 🔓 Unlock the bootloader (required for custom firmware installation, such as LineageOS or Pixel Experience).
• 📥 Firmware of official / unofficial software via fastboot flash.
• 🔄 System Recovery after a crash or "brick" (when the phone doesn't turn on).
• 📊 Viewing device information (model, bootloader version, unlock state).
• 🔧 Installation of patches for modifying system partitions (e.g. Magisk for root rights).
