Desire Z don´t boot anymore, maybe bricked ?

Hi all,
i´ve a problem with my Desire Z.
When i´m starting the Phone it hangs at the HTC Logo.
The first idea was to recover via HBoot.
But i comes a a phone Icon with a red Triangle.
The second idea was to flash the RUU via HBoot.
The programm recognize the phone.
At the flash procedure it comes first "restart bootloader".
But after "restart bootloader and wait for bootloader" it hangs and it comes a usb error message.
Can anyone help ?
It´s a unrooted and unbranded HTC Desire Z.

[Q] How to bring a DEAD Desire to Life (Stuck in the RUU update).

Hi there,
While trying an update (Official 2.3 RUU update that I have downloaded from HTC dev wesite). It stuck in the middle of the upgrade process (Battery issues).
I have a screen error (error 152 as shown on my PC) - the HTC screen shows 4 exclamation marks inside a triangle in the corners (!) and HTC in gray in the middle of the screen (In the RUU window they ask the user to unplug the battery then plug it back again to fix it but it doesn't work for me).
Noice : My device is NOT rooted.
Do I have a dead phone, and is there anyway to fix it?

HELP HTC One M8 Stuck in Android Upgrading Opening Apps.

Hellp anyone can help me?
I bought my phone from Aliexpress Asia version, Android version 5.0.1 and as you know they modded the stock htc android OS to not get or install any OTA updates.
So Here's what I did.
I Rooted with Kingo Root after rooting I used SuperSUme to replace it with SuperSU but after using SuperSUme it rebooted then after the bootlogo in a black screen there started to Pop Error messages SenseHome cannot open with the options to Report or just hit OK. then hitting ok opens another one Google cannot open Facebook cannot open ETC...
I tried going into the Bootloader, Selected Factory Reset, after doing this it loads and the reset logo was there with that cycle picture then there popped "Android is Optimizing 1 to 258 apps and so on" after updating it says "Opening apps" then it is STUCK in there.
I would really Appreciate help, thank you...
