So, my lovely XZ that is supposedly locked to Three UK says bootloader unlockable=no. However, when I hold up and plug in the usb, the light goes blue and Flashtool reports that a fastboot device is connected. Isn't fastboot unusable on a locked bootloader?
I recently got a z2 and it is currently rooted I was unable to unlock my bootloader. When I checked in the settings it said no to the unlockable bootloader. I am interested to know, can you flash the twrp onto a z2 with a locked bootloader and how to do it? I know you could on the z1.
