[Q] Gnex works but no cold boot
Couple of weeks ago my gnex fail to start a boot after my battery used up to %0. I used a wall charger but it did not help, I mean there were no charging screen, no boot animation, no vibration that indicate start boot. I assumed battery was so low, it would not boot enough to charge, so I used an cheap battery charger to charge the battery, then everything worked as expected. this happened one more time, that made me think there was a issue about the rom or some software, but I did not act on it. Then a few days ago my phone rejected to try to boot even with full battery.
I search the forums, and find out connecting to wall charger then inserting battery will trigger a boot, and it really did. Then I flashed official google image to see if it fixes the issue but no luck, then I tried odin flash with repartitioning, still no luck.
Currently I am on full stock on my gnex. If I shut it down, no matter which button/combination I try, it won't trigger a boot. If I connect to a wall charger while battery is in, screen does not turn on and charging does not start. If I remove the battery, connect to wall charger, then insert the battery, charging screen came up, then if I press power button for ~5 second it boots to android like everything is okey, and after boot starts, I can disconnect the charger, no issues about battery.
I have no clue what might be causing this. Power button works, battery works, rom/software works, are there anyone with some ideas what might be causing this?
