Asus Zenfone Selfie ZD551KL

Good afternoon everyone

Friend you could help me?
I see no Forum Topic at XDA about Asus Zenfone Selfie ZD551KL.
So I opened this Topic, for it is a model Zenfone Line 2.
I already have the device.
There is already a Stock Rom for this model phone on Asus Global website.

Please set up a Topic at XDA for Asus Zenfone Selfie ZD551KL.

I can not in any way enter the Fastboot Mode of Zenfone Selfie ZD551KL.
Tightening Button Power more Button Volume - and the screen is frozen.

I have not found the installation Drivers Asus Zenfone Selfie ZD551KL.

- How do I enter Fastboot Mode Zenfone Selfie ZD551KL?

- How do I give the Asus Root Zenfone Selfie ZD551KL?

- How to Unlock Bootloader Asus Zenfone Selfie ZD551KL?

- How do I install CWM Recovery or TWRP the Asus Zenfone Selfie ZD551KL?

I found the Stock Room of Zenfone Selfie ZD551KL with Qualcoom SnapDragon,
unlike ZenFone 5 and ZenFone 2 with Intel.

I not found in the Stock Rom files, fastboot.img, recovery.img, the dnx and ifwi.
Just found the file boot.img.
And the Rom brings a file Dat of 2.80 GB

I not found in any store for sale the Asus Cover
Only found in sites as Aliexpress Cover Wallet style.
The most interesting would be the Asus Flip Cover Original that possesses the
Circle in front allowing use cover Asus.
So it seems there is an Asus model known as: "ZenFone Selfie MyView"

Could anyone help?

Thank you!!
