The phone is almost 3 years old now, and its been acting up lately. It was slow, would freeze from time to time and the general responsiveness was crappy.
She played some game, during which the phone turned itself off, and after a while it would get hot (heating issue). After that it would no longer turn on, the LED doesnt turn on when its charging (or should be at least) and theres no way to enter bootloader/recovery/boot it up. ADB doesnt detect it either.
The LED turned on yesterday while charging and the phone booted up until the HTC logo, then it turned itself off again.
what could be the issue? dead battery or CPU? the battery is also quite old, probably a year+ and it wouldnt last 2 hours on full charge.
