It supposed to work but I got xt1562 so I haven't personally checked this on xt1563 so I can't guarantee that. But in the previous thread people rooted their xt1563 using this method.
I have a xt1563 after some effort I got my 20 digit unlock code.
When I power up my phone on fastboot , I don't see the prompt on my computer that it is connected. but phone says it is.
In the command window , I don't seems to be able to get the "fastboot devices" to show its presence.
Does USB debugging needs to be activated ? "OEM unlocking" button ??
Thanks
