I am helping my brother out here. I did a quick search and couldn’t find anything. He has a Nexus 5 not rooted. He turned it off for a flight and went to turn it back on after it it won’t turn on. Just sits on the load screen w/the four color circles. He say’s the memory is full - so I was thinking maybe that is it? He say’s it just double vibrates and resets after about 15 seconds.
Any idea how to fix?
