Question "fastboot oem unlock" fails

[kxmpxtxnt]

Hey guys,

i try to install a other rom on my phone. I got to the fastbootd mode by using "adb shell reboot fastboot".

But if i now trying to execute "fastboot oem unlock" it says:

FAILED (remote: 'Unable to open fastboot HAL')
fastboot: error: Command failed

Im using Arch Linux btw.

Thank you if anyone know how to fix this

Do It On The Original Cable.....
And Use The Latest Version Of ADB...
Also Try Changing The Drivers Of Your Phone While You Are In Fastboot In Device Manager....

Thank you if anyone know how to fix this Aare on A12 (C.10 or earlier)

Are you on A12 (C.10 or earlier)?
A12 has no fastboot nor BROM. You have to downgrade to A11 or wait upgrade or A13 if Oneplus will fix that. Perhaps they will, perhaps not
