I used superboot to unlock bootloader then ran into boot loop. Tried to install stock from Odin as I have done on my Charge. Now I am stuck on yellow triangle screen can not boot into recovery or odin download screen. When I run odin it goes all the way through process but always get error at the end. Laptop does not recognize phone now. I have drivers installed as I have another GNex that loads fine. what am I missing.
