I'm currently trying to root my Samsung Galaxy S4 Mini, so to install CWM, I boot the device into download mode using my Linux Mint 17.2 laptop:
$ adb reboot bootloader
Now, as intended, my phone boots into download mode, yet fastboot doesn't recognize the device:
$ sudo fastboot devices $ sudo fastboot continue < waiting for device >
lsusb, the phone clearly shows up:
Bus 001 Device 005: ID 04e8:685d Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II] (Download mode)
As you can see above, I run fastboot as root, so it certainly isn't a permission problem.
I can't find a solution anywhere on the internet, so any help is appreciated. If you need any further information, let me know.
Let me throw some additional stuff on you, in case it helps:
