I see your device is working in fastboot mode then why you dont flash it with its original firmware ? i told you to unlock BL with test point method !! Requirements For { Temporary unlock bootloader (USB COM 1.0) }:
- Select your device model from the list
- Connect Huawei device in USB COM 1 then Start
