Won't turn on - Orange blinking LED

Hi,

My HTC Desire 820 won't turn on. It was left unused during some time.

When I plugged it with the wall charger, the LED is blinking orange. I let the phone like this for 2-3 hours, unplugged it and try to turn it on, but it didn't work.

I opened the phone, disconnect and reconnect the battery, try to turn it on, nothing. Try to charge it, nothing.

I tested the battery with an multimeter, and it says ~3.9V. On the battery, it is written 3.82V

When I plugged the phone on my PC, a device called QHSUSB_BULK is detected.

Answer this question I have this problem too

Is this a good question?
