Qualcomm HS-USB QDLoader 9008.

Dec 2, 2016
I am in "Qualcomm HS-USB QDLoader 9008" mode.(EDL Mode ?)
My device Redmi note 4 (4g) is DEAD- only my computer Identifies it as-Qualcomm HS-USB QDLoader 9008.
I have questions:
1. In this situation I need to Unlock the bootloader to flash my device?
2. What is the best method to flash in this mode?
I ask for professional answers and guides that I cold flash my device with ease.
Iportant note: I "hacked" the Internet and did not find a clear answer to my questions.
Thank you very much.
