This question already has an answer here:

I am trying to root my Samsung SM-J400f but I just cant get into fastboot mode. As soon as I type following command :-

adb reboot bootloader

My device just reboots and doesn't enter into fastboot or any special mode. I have checked "OEM unlock" option in develop options. Also I tried entering into fastboot mode by pressing Volume up + home + power keys but it just starts normally like nothing have just happened. Pls help me. Btw, I am using ArchLinux

  • This question has been asked and answered many times... Samsung devices do not have "fastboot", they use a proprietary download mode that requires special software like Odin or Heimdall. – acejavelin Apr 16 at 13:48
