Huawei P7mini (G6-L11): "fastboot devices" says "no permissions"

[yeolesourpuss]

Hi all,

I have a Huawei P7 mini (Ascend G6-L11, P7MiniV100R001C432B370, CUSTC186D005) and I'm trying to unlock the bootloader in order to install TWRP.
Having enabled "Developer options" and "USB debugging", I can access the device via adb.

However, after "adb reboot-bootloader", issuing the command "fastboot devices" only outputs:

no permissions	fastboot

The screen reads:
FASTBOOT&RESCUE MODE [...] PHONE Locked

"lsusb" reports the device as:

Bus 002 Device 015: ID 18d1:d00d Google Inc.

Probably that explains why an additional "adb oem unlock <code>" just outputs:

< waiting for device >

Is there anybody who has an idea where I may have taken the wrong turn?

Thanks!

Needs "sudo" on host

Hi all,

However, after "adb reboot-bootloader", issuing the command "fastboot devices" only outputs:

no permissions	fastboot

Apparently, fastboot needs to be run as root (sudo) on the (Linux) host to work.
Alternatively and better, udev should be configured to allow access (source: askubuntu).
