[Q] Please help me for unbrick my D802

Hi all,
I am so sad and feel myself as a idiot.
I had D802int version of G2 with rooted and PhilZ Touch recovery which is based on CWM.
Due to not deliveried to my country of KitKat i tried to update my phone with this guide
Everythings were fine. After that i tried to change my TRWP recovery with CWM for external usb storage to restore my nandroid backup and i follow this guide
But I think missed some instruction so my phone stayed in black screen with LG logo (bootlogo - no animation just frozen)
When I try recovery mod it says Secure: Booting error Cause: Boot certification verify on white screen and reset rapidly.
So i check several topics and i applied also download mod and back to stock (kdz uploader method)
For download mod it couldnt jump 2nd step stayed in like this

"lightbox_toggle_sidebar": "Toggle sidebar"
}
it couldnt go on 2nd step like this
when i plug usb cable pc didnt recognize as well (no plug-in sound for driver)
Can you help me pls. If I rescue my phone i will quit a long time for this kind of works i think

He just stated that he can go to download mode.
OP your issue is drivers. The phone is not connected to the pc. Try uninstalling and reinstalling drivers and see if that help

Install drivers manually and disable windows update to override whatever windows wants to install from there...

The issue was happened when trying to flash some LG G5 adapted rom on the LG G2, so the bootloader or the recovery got damaged. What I finally did was to force qhsusb_bulk short circuiting the capacitor and then using SRKtool_2.1_droidth.zip to use the unbrick method.
Then, you can reboot to download mode to use LG Flash Tool or reboot to recovery to flash the partition of your particular rom using dd (once you upload the partition images to the smartphone sdcard).

Hey scandium, I know it's been years since you've posted this,
but I was wondering if your phone symptoms were unknown device on any pc+slow charging with any charger. I currently have a G2 in this situation. It works, but has no USB connectivity whatsoever, and takes ages to charge. Do you think that shorting the capacitor and flashing the phone from scratch would fix it? I'm afraid of trying it and when connecting to the PC still get the unknown device problem and end up with a brick. Thanks in advance.

Stuck at ASUS IN SEARCH OF INCREDIBLE screen

I've seen this kind of problem alot here but here's my problem and why nothing helps.
Basically I wasn't updating my device I was just texting or something like that when my phone went black except the system outline(you know time, signal, wifi/net conection etc. on upper part of phone) so I forced it to shoot down and after that when I try to turn it on it's stuck at ASUS logo(I can't take picture of my phone but it's same as on the picture:

}
Now I tried factory reseting it and entering the recovery mode, none of it seems to help and the problem is that my PC can't detect my zefone when I connect it(and I'm pretty sure it wasn't detectable before this problem either so I don't think those are connected issues).
Any suggestions?

are you tried flashing system via ''apply update from adb'' command of recovery

Yes, as grady_8 said, Flash update using ADB from your recovery, but you need ADB and Fastboot drivers first, then your PC will able to detect your ZF.

https://forum.xda-developers.com/zenfone-5/help/bootlooped-bricked-returning-to-stock-t3358662
try this guide

You must be downgrade first, because the lolipop firmware not support adb flash. Download firmware save at same folder with file extracted. (Version . UL_WW.2.22.40.54-user.zip. )extract it to new folder, then click shift+right mouse, open command here. Then type fastboot flash boot boot.img then' fastboot flash recovery recovery.img , then ' fastboot flash fastboot fastboot.img. after that reboot to recovery manualy, then aply update from adb . Then In CMD type ' adb sideload <the name of firmware>.zip (example = adb sideload UL_WW.2.22.40.54-user.zip ) Wait the progress. Then finish.

Upgrade download failed!
This is caused by download interruption. Recommend you use download tool try again.
You need to confirm if there is failure message on download tool or not when you see this error.
Also please check if you disconnect USB or click stop button when the download is not finished yet.
You can press any key exit this message.
"
It shows up whenever I try to reboot or go to recovery mode. Nothing works now and USB cannot be recognized except for Fastboot but it didn't help me with booting or flashing anything.
Any Idea?

Yes I did. It starts flashing well until it requests rebooting into fastboot. Once the phone reboot it goes back to that error message.
