My device is Samsung Galaxy S3 I9300 and I did a complete factory reset. The device is NOT rooted yet. It works properly. I can do all of the following with my device:

  • Power off using device keys.
  • Start in recovery mode and download mode using device keys.
  • device is detected properly in normal mode and recovery mode by adb when is connected to PC through a USB cable
  • I am able to reboot the device using adb reboot command
  • adb reboot recovery works well.

The problem is that if I run adb reboot bootloader or adb reboot-bootloader commands, the device is booted in normal mode, NOT in download mode. The only way to reboot the device in download mode is to use the Power + Volume Down + Home keys

From my experience with Samsung devices this is not a bug but rather a feature. The "download" AKA "ODIN" mode on Samsung devices is a proprietary alternative to bootloader/fastboot mode and I don't remember being able to boot to this mode in other than the hardware way.

  • Could you provide the output of adb help? download option is not supported with reboot. See source code here: android.googlesource.com/platform/system/adb/+/refs/heads/…

  • As far as I know, adb reboot is shorthand that does the same thing as /system/bin/reboot binary, whose syntax is usage: reboot [-p] [rebootcommand]. From testing, reboot commands for Samsung-based devices are recovery and download. Samsung devices have a proprietary implementation of fastboot/bootloader mode called download mode, hence download option.
