I am trying to install Lineage OS on my Nokia 3 TA 1020 and at first I can't get into fastboot via ADB (i get a -1 error), although I do see the devices with adb devices.
I enter fastboot manually via recovery mode and then when I type fastboot devices on command prompt it shows nothing. Also, when i try to flash TWRP anyways, I get a "waiting for device" message and nothing happens on both screens.
Anybody got any idea? I got debugging enabled and OEM unlocked from dev options on android.
