Leave it a while then try powering it back on

na, when you hit the safety shutdown temp, all it does is shut down, you can boot it right after. ive reached it many times(on purpose), it works.
what the op is describing sounds like the rlod on the nexus 4(red light of death). it happens when the phone thinks it went below 0%. on the n4 there are two solutions, one works sometimes, the other all the time. the one that works sometimes is leave it on the charger for several hours, then try to boot into the bootloader, then shut off the phone from there and keep charging. the method that works 100% is to remove the back cover, disconnect the battery, then reconnect it. this is a hard reset for the battery, and works 100% of the time on the nexus 4.
