Trying installing Lineageos, Reboot my phone but stucked now in the Odinmode I am trying to install LineageOs on my Samsung Galaxy J5. Currently i am trying to to reboot my Phone... I writ this in my command:
adb devices 
List of devices attached 
1709f084 device emulator-5562 offline

adb reboot bootloader 
error: more than one device/emulator

adb devices
List of devices attached
1709f084 device emulator-5562 offline

adb -s 1709f084 reboot bootloader

fastboot flashing unlock &lt; waiting for any device &gt;

Afte writing the command adb -s 1709f084 reboot bootloader i t got in the odin mode. After writing the command fastboot flashing unlock nothing changed...
What am I doing wrong?

Samsung doesn't have fastboot mode . Use odin to flash your device . If you search online you will find Odin for your computer . Install it . Most likely the Linageos uses custom recovery to flash . If so flash TWRP or any other custom recovery available for your device and flash Linage from there . If you are tring to get out of odin mode . press (power + volume down) to force reboot . if that doesn't work try volume up with power key . Before flasing anything make sure you have activated bootloader unlocking in Devlopers settings :)
