Help Can't unlock bootloader on HTC Desire 816G dual sim

[Hamidreza A]

Hi everybody
I have HTC 816G dual sim. I tried unlock bootloader via htcdev.com but I have a problem. In my phone settings it doesn't exist power to uncheck fast boot! And when I turn off phone and press volume down + power enter to system recovery. So I tired in cmd and typed "adb reboot bootloader" to enter fastboot mode and after that I typed "fastboot oem get_identifier_token" but it doesn't work and gives me this error:
FAILED <remote: unknown command>
Finished. total time: .004s
I don't know what's the problem!!
Is anybody know what is the problem?
Thanks a lot

When it reboots to the bootloader, does it say Fastboot USB anywhere on the screen?

What options do you see on the phones screen?

 

[Hamidreza A]

Yes, when I reboot to the bootloader, it just says FASTBOOT MOD...

Unplug the USB cable from the phone and reinsert, does it change?

What version of Windows are you using? In the bottom right of the screen next to the clock, is there an icon that implies the PC is searching for drivers/it's found a new device?

 

[Hamidreza A]

No, it doesn't.
I use windows 7 x64. Yes, a new device recognized.

And I take it the drivers have installed sucessfully? I'm guessing HTC Sync isn't running in the background? If it is, close it.

 

[Hamidreza A]

Yes, the drivers installed successfully. HTC Sync was running in the background, I also tested without HTC Sync.

I am having the same type of prob. When I open the command screen, it doesn't list android on the line where you type the command, like the screenshot shows, it just lists "user"
