To make a long story short (like you did in the OP), I have to same problem

The cause: flashing newer firmware version. All the symptoms are exactly the same. When I get home from work today I will try these 2 things, they are a little variation of what I already tried:

http://htc-one.wonderhowto.com/how-t...a-adb-0154361/

http://www.androidlegend.com/how-to-...ndroid-device/

I don't have much hope that I can fix it myself and am already in contact with HTC though. The main problem is that I'm in Argentina and I bought the phone in Germany..

You didn't find any other possible fixes, right?

Hi, how did this go? I just bricked mine doing the same thing... upgrading firmware. I can't get it to respond to any of the suggested methods. What sucks is that the firmware update dialog in fastboot looked good to me. Sucks...

Cool, thanks! I wonder if a vm running linux would work. All my machines are windows. Not sure how the vm would handle the usb connection. I'll have to see what I can figure out.

Thanks!

I'll be damned! This worked! I just popped in the latest Ubuntu liveCD and went to town. My phone is now up and charging. Once it's at 100%, I'll try pushing TWRP recovery to it and restoring my last backup.

Thanks again for sending me to that link!

Done and done... pushed TWRP and restored my last backup. It's as if it were never bricked! And it also updated my kernel, which is what I was trying to do in the first place.

Just for future reference for anyone coming across this thread, there are two distinct types of bricks being discussed here.

The first results from a borked firmware update. In this case, everything works on the hardware side, it's just that the phone can't boot because the firmware is messed up. This is usually fixable using Dexter's method.

The second, and the problem experienced by the OP, is more serious and is hardware related. I have seen this occur with multiple HTC models. Something related to power management on the motherboard dies so that the phone no longer can no longer get power to start up. When this happens, the phone will typically have shut down without warning despite having a good battery charge. I have never seen or heard of a fix for it beyond returning it for warranty repair.
