This is my older son's N7. A week ago he was playing some dumb game and it froze on him. He, intelligently, immediately restarted the N7 and continued to try to play. This happened about 7 times. The last time he said the screen glitched and it turned off. He then plugged it in and it got very hot according to him, for how long I don't know.
So now I took it apart. The battery was 3.4v-ish and not charging, so I hooked the usb up to it directly and charged up to 4.09v and tried. Still won't turn on (and yes I tried all combination of buttons and lengths). Plugged in the usb, tried again, no luck. But I did notice the qualcomm chip getting very hot very fast.
So what is the next step here? I cannot find a lot of information on this as 99.9% of the time someone just ran their battery completely dead and jumpstarted it back to life. I don't have access to proper reflow equipment so thats off but I'm not against a ghetto heatgun reflow. This thing is long out of warranty so I'm willing to try some invasive tricks on it.
