Default Zte v987 bricked ! Help plz!

Hello guys i need your help as my phone does not work at all! Originally I wanted to change my rom but the recovery menu was in Chinese and so accidentally i erased the root and rom that was in it , so when opening the phone stucks in ZTE's logo. So I found a management tool for rom and root and a guide to recover the operating system of the mobile. Unfortunately I did not succeed and instead accidentally tapped the format button that it was in Sp flash tools and so now the zte v987 does not open at all. All it does is to be recognized by the computer and the sp flash tools like usb. Finally i download the sp flash tools and the green circle was shown up but when I press the power button and the volume up to open the phone, it does nothing , just black screen .Please help me because I left without mobile.

Also where can i find all these missing files shown up below in the picture? ?

I need your help please,
Michael.
