Root D320n Download Mode error

[Kitemmuort]

When I try to start my device in download mode it comes out this screen:

I tried to hold volume up key 1-2 minutes but nothing happens.
From the pc (connected with the smartphone) I tried

fastboot devices

But the terminal output is

no permission       device

Please help me

You need to have your USB cable plugged in during the key combo - not after seeing this screen.
Turn of your device, take out the battery. Then plug USB in, put the battery back in, press VOLup + POWER.
When the phone vibrates, release POWER and wait.

My device boot ONLY IN FASTBOOT MODE.
It wan't boot in recovery, it wan't boot normally, IT START ONLY IN FASTBOOT.
Please, if you have boot.img system.img recovery.img and other files that can be flashed via fastboot, please upload them. I would like to recover my device...
Thank you in advance!

Did you run cmd as an administrator (if your OS is Windows) ?
What exactly did you do before it happened?

Yes, when I do

sudo fastboot devices

the pc recognizes the device. I can also flash recovery, boot etc, fastboot works at 100%
But the device don't boot in download mode (I want flash stock ROM).
Before of this, I've wiped all in recovery (dalvik, data, system, etc.).
Now I have flashed TWRP recovery via fastboot and I flashed cyanogenmod, now the device boot and work but don't go in download mode.
Sorry for bad language, but I'm not English...
Thank you in advance
---- update:
I've tired to do

adb shell

then

su

then

reboot download

but the device reboot normally, no in download mode...

How to slove:
Download this https://www.mediafire.com/folder/287nt8sdf31c8/LAF for your device (my is D320n)
Then, go to download directory and rename the file in laf.img
Open a terminal (root) and cd /Your/Download/Directory
Boot in fastboot, connect at PC and

fastboot flash laf laf.img

now reboot with

fastboot reboot

and reboot in download mode, you can see the download screen!
