This is with Ubuntu 13.10 on the host and a Sprint Samsung Galaxy S4 SPH-L720.

When in normal mode, 'adb devices' finds my phone.

I do 'adb reboot bootloader' to reboot my phone into bootloader mode.

'fastboot devices' comes back empty. 'sudo fastboot devices' also comes back empty.

I have setup the udev rules file accordingly (replaced my real login with myuser)

~  cat /etc/udev/rules.d/51-android.rules     
SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", MODE="0666", GROUP="myuser"

lsusb returns the following (fyi, the device is an S4, not an S2)

Bus 002 Device 006: ID 04e8:685d Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II] (Download mode)

I've read a ton of articles on this and I can't get this working. Any help is appreciated. Thanks!

  • I don't know that the S4 has a fastboot mode. Typically you would flash Samsung devices with Odin. – eldarerathis Dec 18 '13 at 04:52
  • I believe it's called download mode, but it definitely has it. This probably differs on the different carrier variants. – clay Dec 18 '13 at 13:49
  • I know about download mode, that's what Odin is for. I believe that's different from a fastboot mode, though. For example, my old Galaxy Nexus had both modes, but I think that was because it was a Nexus device. I don't think that carrier branded Samsung phones typically have a way to use fastboot. – eldarerathis Dec 18 '13 at 14:53
  • Depending on what you want to do with fastboot, there's an alternative for Samsung phones called Heimdall. I used it on my SIII mini to install TWRP. – To Do Jun 02 '17 at 08:00

Accordingly to the answer to this question, Samsung devices do not support fastboot. This thread on XDA Forums states the same.
