Couldn't find much related to my problem so asking here.
How bootloader looks on Blade 3? Every time after "adb reboot bootloader" I get stuck on ZTE logo screen
and adb devices command shows empty list. I got all correct drivers installed. My phone is branded by Virgin Mobile so not sure
if bootloader is different by any way. Some users says BL mode is when green android logo shows on the screen.
In my case got a white/grey ZTE logo with dark background.
