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 < waiting for any device >

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?

Greetings :)

    samsung devices don't have fastboot mode, therefore no fastboot command will work

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 :)

  • Thanks man :) i got it...I did the hole process until i realiced that lineageos doesnt have a custom rom for the samsung J5 or the samsung galaxy S5 mini. So the hole effort was useless... Do you now a lineageos based custom rom for the J5 or S5 mini? Greeeting :)

  • check this forum.xda-developers.com/galaxy-j5/development/… I don't have a j5 so I cann't tell if it works . But if you are looking for a custom rom xda-dev is a good place to start . But before you flash it make sure it's for you device model . It seems samsung has several models named J5 Aug 14, 2020 at 11:16
