FAILED (remote: Command not allowed)

[BentoEspinosa]

My phone is not rooted, but the bootloader is UNLOCKED (for sure!).
I'm trying to install a custom recovery, but am getting this message:

FAILED (remote: Command not allowed)

Why? Do I really need to root my phone in order to install a custom recovery?
Or how else could I solve this problem?

It may help to know which device you're using. Is it the Huawei P9, as you mention in your other posts?

 

[BentoEspinosa]

It's a Huawei P9 Lite.

You've been to developer options and OEM unlock?

 

[BentoEspinosa]

The option OEM unlocking is grayed out (I can't change), probably because bootloader is already unlocked.

 

[meattray]

Strange. I still have the option to turn that on or off. What instructions are you using to do this?

 

[BentoEspinosa]

It happens when I try to transfer the recovery installation file to the phone on fastboot using adb.

 

[meattray]

Adb debugging more is on?

 

[BentoEspinosa]

What do you mean?
USB debugging is on.

 

[meattray]

Er sorry yeah that's what I meant. If you type fastboot devices does your device get found?

 

[BentoEspinosa]

Of course, otherwise I wouldn't get that type of error message.

Something is amiss with the settings. Can you try wiping the system cache or doing a factory reset before this?

I met this problem too.At the first time I used Ubuntu-16.04 to operate my phone(Huawei g750-t01), but it failed though it can detect my phone. Then I switch to Windows do the same thing, it's no doubt that the command failed again. Finally I install HiSuite and it worked magically It seems that it is drive problem.
