I was charging my phone over night(no power surges), and in the morning the phone wouldn't turn on. I was charging the phone with a charger for a S4 phone but I can't see that mattering, b/c you can't over charge a L-ion battery. I tried removing the battery for extended amount of time and tried other batteries but still nothing, There are no lights blinking or nothing happening when I try to turn it on, tried holding all buttons also. I have a parts phone, so I you guys having any suggestions on what happened I would appreciate it. Thanks!
