My cell was a little wet and then when I was charging it it indicated: battery temperature too low, so it was impossible to recharge it. Now that the battery is empty it doesn't light up and the only thing I can do is to display the custom os installation menu. The battery seems to be charging, because when I unplug it in custom os mode it doesn't turn off. I tried to turn it on with the power + home + volume up buttons, it doesn't work.
Thanks
