The Download Mode on Samsung Galaxy devices is also known as the Odin Mode. All devices with the Download Mode support firmware flashing via manufacturer-specific official tools like Samsung Odin, LG Flash Tool, Nokia OST Tool, etc. However, you can’t execute Fastboot commands in the Download Mode. Having booted your phone in the Fastboot mode, you can flash stock firmware and factory images. While most Android devices have a regular bootloader and fastboot mode, OEMs like Samsung, Nokia, and LG phones come with the Download Mode. You can also use the Samsung Download Mode tool called 300K Tool and ADB command to get into the Bootloader or Odin Mode and Recovery Mode without keys. Today, we’ll see how we can boot into the Samsung Download Mode using hardware keys. Every user must know about the methods to boot into them. While the bootloader or fastboot mode allows us to flash firmware and recovery files, you can wipe your device and flash OTA ‘update.zip’ via the recovery mode. All Android devices have a bootloader, fastboot, and recovery mode.
