it wont work , that is what caused the issue, there is no adb or fasboot commands as the phone has nothing to load or read, it was flashing the official latest stock firmware using the flash-all.bat, then after the first rebbot and waiting for devices it goes to a black screen and shows what i put in the screen shot,(i believe the battery died during flashing) there is two modes it goes into the qusb which is the qualcomm download mode and some other mode i cant tell neither can the pc device find drivers to read the phone, techinically this phone is not fixable using normal methods , but i believe there is a way to flash to firmware back on,i have looked into using edl and qspt flashing but it still doesnt read the phone, any help would be greatful i have device protection but they are sending me a refurbished phone i would rather try to fix this before i do get the replacement, as it was a new and working deviceYou can try to go through the applicable steps in this guide:
