I'm trying to install ubports to a nexus 5, 16 gb that was running android 6.

I tried with magic device tool and the ubports tool. I was able to get the installation to begin but it then hangs on a black screen that says google. I can reboot and get to fast boot. I can get to ubports recovery. I am not sure how I can get the system to boot from there.

I tried reinstalling four times but it's hung on the black screen every time.

Do any of you know what my issue could be?
