Infamous Nexus 5x bootloop: why does heating or battery drainage allow it to boot? I have been tinkering with my good old bootlooped Nexus 5x (how I wish there was an affordable Pixel these days!) and after naively thinking it had recovered spontaneously (it seems to have booted because drained battery?) I gave up on it. Then I saw it come to life again as it was bootlooping on top of a hot laptop. I now boot it at will by placing it on my espresso machine's cup warmer! 


Why does this happen? What component needs to heat up in order
for the system to work? Before the bootloop, why did it work at 
'normal' operating temperatures? What changed after the bootloop?
Why would a drained battery also do the trick?
you should try the 4core fix.

If you can boot your phone and enable oem unloock you are good to go.
