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?

This may help you:

Hold down "VOLUME PLUS" + "VOLUME MINUS" + "POWER"-Button at the same time for 10 seconds.

Hello there, i had the same problem with my phone ,most of the HTC smartphones have the exact problem of charging and the red light blinking . I took my 820 to the htc service center and they told me that the charging port was damaged and this is a common problem in many devices they gave me a bill of 3000 INR for replacing the port as well as the battery with one month warranty. but if you are low on budget and don't want to spend that much you can get both of them replaced at a local shop for 1500 INR. Battery costs around 700-800 while the port costs around 500-600.Your phone will no longer have any charging issues . believe me its no software problem .
