MOTO E not turning on after upgrade Run the update on my moto e yesterday, and after installation, it shut itself off an couldnt turn it on again.
I got 1 or 2 blink led while pressing power for 10 seconds (this only if it is plugged), it doesnt do anything if unplugged.
Tried 2 min hold power down, power and volume down, and several other options.
Tried several charger, LG, Samsung, RPI2 (5v 2a), pc/notebook usb, and of course the original charger. eft it all night, and several hours during the day.
Nothing seems to work, battery still cold afetrr so much time charging.

A few minutes ago, i removed the battery and plug it to a charger and it seems it wants to boot, see several blinks but the screen never turns on so the phone, after a few seconds it stop blinking.
After that i connected again to the notebook, and the notebook seems to detected but throws an error and disconnects usb.

What is going on????
Any help would be helpfull
Voltage is not a good indicator normally of State of Charge (SoC) for Li Ion batteries, since the battery can show higher Voltage but not hold charge. Graph 2 highlights the relatively flat Voltage curve, compared to SoC drop 
Voltage of a fully charged battery should be 4.2V (see table 2). 


Seeing your comment on battery voltage being less, after 2 days of charging (less than 3V), surely you have a problem, since the Battery is considered "dead" at these levels

Possible fixes


I would suggest you to borrow a battery and see if it works fine. If it does, the solution is obvious- of changing the battery. If it doesn't help, it points to a  possible hardware issue in the charging circuitry, best rectified by qualified folks
Since the problem occurred after an update, it is possible that battery charging related drivers were not properly installed/ corrupted. This can be checked by reverting to earlier build or re flashing the update , which is difficult given that you can't power on your device, and would again need service center help


I am more inclined to believe that  it's on account of botched updation, since Li Ion batteries don't "suddenly" die
