Asus Zenphone 2 (Stuck on usb logo) - ZenFone 2 Q&A, Help & Troubleshooting

Hi guys,
My Asus Zenphone 2 (2gb Ram) just showing usb logo. I guess it's bricked.
I never tried rooting it or install any rom on the phone.
I've searched the forum but couldn't find any solution on it.
Can any guys please help?
(It's not even going to recovery mode. I've tried the power+ vol+ button method... but not working. just the same logo only)
Thanks in advance.

Have you tried the Asus flash tool to see if it recognizes the phone? There is also an Intel flash tool which you could try, you may be able to flash the raw ingredients and get back to normal and flash through bootloader to update both threads for those tools are explained in the Zen 2 forum, search for them

Right now I'm following a guide to unbrick an Optimus G. Downloading the FW is the first step. It doesn't seem so difficult. If I manage to unbrick it, I will share step-by-step guide here.
I'm f***ed up! Nothing works. Who can help me really I want to kill myself.

While pressing both volume up/down together, connect your phone to pc via usb. Open LG Mobile Support Tool. From options, choose upgrade recovery.

As I recall, last time I tried, it can't find my E988 through USB.
I did install driver before I connected the phone.
Any other setting required?

As I told you, you need to be on download mode. Follow these steps:
1) Pull out the battery. Your phone will be turned off
2) Insert the battery but the phone shoud stay turned off. Plug usb cable to the phone but not to the pc
3) While the phone is off and battery is in, press both volume up and down buttons together (Do it with your single hand)
4) While you are pressing the buttons with your hand, plug the usb cable to the pc with your other hand.
5) You should see phone gets into download mode (DOWNLAD will be written on the screen)
6) Now the pc should recognize the phone.
7) Open LG Mobile Support Tool
8) You should be able to see that it recognizes the phone. If it doesn't, repeat the first 4 steps when LG mobile support tool is open.
9) After your phone is seen by the pc, choose Upgrade Recovery from Options.
10) It will check the FW from internet by using the imei Number of the phone or you can enter E988 and your serial number manually
11) Then it will download the FW and recover your phone. It will take time according your connection speed.

Thank you. Finally, Mobile Tool detected my E988 and is downloading the firmware now.
Something wrong with my Win7 , it just can't find the driver for E988.
Then I open XP mode in my Win7 and try again. The phone was detected and Mobile Tool open for action.
Thank you again. My E988 already bricked over a week.

d855 bricked?

I'm in a bit of a pickle...
Phone is dead, I'm unable to wake it using any method, however PC sees the device being connected. I have tried to restore TWRP backup which was completed correctly but then phone stuck and failed to wake up again. I have tried to unbrick it using the LG flash tool and dll +tot files however this method fails each time -with factory model check error - and download fail notification. Right now im waiting for kdz file to download (im using the tool checking my imei to select correct one) but it takes ages with my internet.
Anyone has any ideas? Am i doomed?
Hi
Happened to me also. I got out of it by using LG flash tool and clicking on options and selecting restore recovery. It puts it back to stock and you then need to reroot etc.

Options? On mainstream there isn't any. Is it on the 2nd screen after adding the kdz?
Current progress
Phone:
No download mode
No boot on the phone
Device acts dead - only visible on my pc (serial port LGE)
PID and IMEI not available to read using LG flash tool 2014
Tried
Loading KDZ file - connection failed
using tot and dll with flash tool - Failed to connect to device
Read something about laf.img using adb... Anyone has any other ideas? Funny enough when I was searching forums I was not able to find more info about cases when device is not waking up at all. but now i see few very similar threads around? Possible flaw somewhere?
Please take a SC of your device manager...

Thank God it is showing a serial port, try flashing with LG tools 2014, let me find a fix for your download error...
EDIT: Is your phone by any chance plugged into a usb 3.0 port? If yes then please plug it in a usb 2.0 port and try again...
I hope you are right. Screens hots should be updated same link:

Laptop has no usb3.0 so im safe there. Tried 3 cables as well. Not sure what was it shown it was I think Android device but it is no longer there. Just the com port. Lge
@quintaar
Sorry my bad. I should have said LG Mobile support tool. If you have it click on the options and select Upgrade recovery.

It might be the PC (work pc at the moment and some IT limitations on it) however drivers installed ok, software confirms that I have latest software on my device - when phone is connected to the pc. After running Recovery Upgreade, it gets problem with comunication between the pc and mobile. in troubleshooting asks to power on the mobile (which I cannot do) before retrying. Also I have installed LG usb driver from outside as options coming with this software seem to be for really old models?
A thing I tried with another G3 was to connect the phone to the PC without the battery and then insert the battery, disconnect from phone and then remove battery again then insert and hold volume up and connect the USB to the phone again and it went into download mode and allowed the use of LG support tool as before.
Its worth a try!!

No dice... so far. I'm back home in 2 days when i can try all of this again making sure that PC is not restricted from any functionality... although it does sucks to not to have a phone until then. If you get any ideas I'm happy to try it as well.. as not like i have anything to lose at this point.
