[Asus Zenfone 4] stun3i:
Hello guys, I need help with my bricked A450CG.

Here's the symptoms:

Power on : Stuck at ASUS logo

Hold Vol+ and Power: Stuck at a screen with green android wearing yellow cap, nothing else

Hold Vol- and Power: Nothing happen

Charge: Show a battery icon with a lightning but no animation

In short, I cannot boot the phone, can't get to droidboot nor USB download mode.

I have tried following these guides:

http://www.gadgetuner.ml/2014/12/how-to-unbrick-asus-zenfone-4-struck-in.html#

All those guides give direction to unbrick zenfone which struck at USB icon. However, in my case, the USB icon is not even showing.

I could install iSoC driver, and when I hold Vol- button and connect the phone to my PC, there are CloverviewPlus Device showing in Device Manager, and in xFSTK: CloverviewPlus target detected : 1. However the screen of the phone was still showing nothing, no USB icon, just black.

I have tried download the bin files from several sources, but they all give the same result in the end. Here is the log of xFSTK

20:15:54 - Success: Download of FW and OS Completed.

The last line says Success, but some lines above give FAIL. And I still couldn't get into droidboot.

I also tried to download the RAW file hoping to extract the bin files from it, but somehow all the raw images for A450CG I found on the net are corrupted and couldn't be extracted by Winrar or 7zip. Here is one example: https://drive.google.com/file/d/0B9rsmgSMnm-na2s3WXNxZjBUTXM/view?usp=sharing

I have surfed through xda and the net and found a few people who got the same problem (yup including no USB icon) but none got a working solution so far. So...I guess some experts are required here.

Thank you.

P/S: This phone belongs to my girlfriend, so please don't ask me how she bricked it.
