So i am trying to get 4.04 on my Nexus. I am unlocked and rooted. To unlock i used SDK and to root i used the superboot. I am now launching CWM via fastboot but when i choose the update.zip (from this link) it started but then ends up going Error in /sdcard/update.zip (status 7). I have downloaded the update from multiple places to see if that works but i have no idea. I would prefer to stick with fastboot and not have to actually install CWM for this to work. Anyone know what I need to change? Been searching and trying things for about 2 hours now.
