What is Fastboot? (And Why It Matters)

Fastboot is a protocol for modifying your Android device’s firmware directly from a computer. Unlike ADB (Android Debug Bridge), which works within the OS, Fastboot operates at the bootloader level, making it indispensable for:

  • Unlocking bootloaders (prerequisite for rooting/custom ROMs)
  • Flashing partitions (recovery, boot, system)
  • Debugging boot loops or bricked devices
  • Installing factory images (stock OS restoration)
