i am wanting to unlock the bootloader on my Samsung Galaxy A5 2017. The problem that I have encountered is that fastboot doesn't actually detect my device but adb does!

I have tried 'adb devices' and that finds my device but when i try 'fastboot devices' it doesn't appear with anything.

If you have any solutions please tell me!

  • Please make yourself familiar with the basics about the two first (our fastboot tag-wiki would already answer your question). It's totally normal that when ADB is able to detect your device fastboot is not – and vice versa. – Izzy Apr 11 '18 at 10:44
  • I have already read that and none of the solutions work. – EthanSteel Apr 11 '18 at 12:16

    So you have booted into fastboot mode, and there fastboot devices did not detect your device? What OS you're on? In case of Windows, the correct drivers are installed? Note that many devices present a different device ID when in fastboot mode. – Izzy Apr 11 '18 at 13:11
  • Yes, when i boot into fastboot mode and run the command 'fastboot devices' no info appears. I don't know what drivers exactly if its like usb drivers or something but all i can find on the internet is usb drivers. Also im on windows so... – EthanSteel Apr 11 '18 at 17:42

    I have found the problem, the computer itself doesn't detect my phone when its in fastboot mode. idk why but i will do some research. – EthanSteel Apr 11 '18 at 18:33
  • When you figured it out, be welcome to answer your own question – might help others in similar situations :) Good luck, and fingers crossed! – Izzy Apr 11 '18 at 20:46
  • After a lot of research, i still can't find a solution :( Any ideas? Im not sure if it's usb drivers because i downloaded drivers from smart switch. Plus my phone is detected when charging and turned off completely. Has Samsung possibly put in some kind of security feature like knox? idk i will keep trying – EthanSteel Apr 12 '18 at 17:54
  • Good look, but somebody else must pick up here – I'm double-out (no Windows, no Samsung here). – Izzy Apr 12 '18 at 18:49

    According to someone on xda fastboot isn't supported on Samsung and i just need to enable oem unlock in settings :/ – EthanSteel Apr 13 '18 at 19:30

    That someone might be right, I vaguely remember heaving heard the same: on Samsung devices, there instead is "Download mode" to communicate with Odin/Heimdall. – Izzy Apr 13 '18 at 19:41

    @Izzy: You are correct. This answer confirms it. – unforgettableidSupportsMonica Dec 04 '18 at 23:15
  • Well i didn't know that answer was a thing... – EthanSteel Dec 04 '18 at 23:19
  • @Slinver I take that as confirmation (and mark this as duplicate). If I was wrong, let me know. – Izzy Dec 04 '18 at 23:59
