Brick QHSUSB_Dload

hello people today have inadvertently p880 flashed a kernel of 4x HD on my Optimus G E975. (I had had it for my wife on my phone saved)
Unfortunately, since then nothing works.
I no longer get the recovery I'm no longer in the fastboot and not even in the download mode.
Only when I connect the phone to the PC, the status lamp lights red briefly
The phone will be visible to a Windows XP PC as QHSUSB_Dload unknown device.
I Have found a Link on XDA but this is in chinese.
Does not come with the instructions further unfortunately.
Has anyone had experience with it?
Can I save the phone yet? Urgently need your help.
Sorry for my Bad Englisch.

Did you only flashed a kernel? Can you still get to the bootloader to flash kdz? If not you probably have an hard brick translate this page with google translate
http://bbs.gfan.com/android-6269182-1-1.html
It has an way what could work.
Do you still have guarantee to return the phone to lg? Cause it might get fixed i dont want to let broke parts or what to get new one i think that is wrong but this is fixable you justneed the knowledge and the tools.

Turn on you phone while holding both volumn + power buttons. If that doesn't open the download menu, you need to take out the battery; connect usb cord to your device, while holding all the buttons (volumes and power) plug the other end USB cord to your Pc, and put the battery back in, then let go of the buttons. Keep try both of those methods, and you should be able to get the download menu to flash the firmware. Otherwise you can't do anything.

Have you tried all the methods I mentioned in earlier post to turn on the download mode? Try them first, and if those methods don't work, then you can plug your phone to a PC and look under the device manager what your phone appears as. If it's recognize as a lg device, then you should keep trying those methods I've mentioned until you get the download mode. However, if your phone is not recognize at all, or it's been seen as something that has word Qualcomm qdhs something in it, then phone is hard bricked. If that is the case, then I can only suggest you try the following link, get the jtag service, else get yourself another phone. Because hard brick, if you have never heard the word before, it means just how it sounds, you got a hard brick on your hand.

[Q] How to un-brick a wrong bootloader flashed 5x (in qhsusb_bulk mode)?

Hi,
I made a brainless mistake. When "fastboot flash bootloader", I chose a wrong image file. After rebooting, my 5x keep in blank screen no matter which key pressed. That means, no fastboot mode.
Plug it into a PC with USB cable, the PC can recognise a device connected and name it QHSUSB_BULK.
Following http://forum.xda-developers.com/nexus-5x/help/req-help-to-unbrick-t3251740, I installed all drivers but Windows still can not find the driver for QHSUSB_BULK. And LGUP also can not find mobile device.
What should I do? Is there any way I can flash the correct bootloader? Thanks a lot!

any luck? I did the same dumb thing.

i've got qsdloader 9008 , no recovery , no download mode , sometimes it goes to bootloader . but can't hang on it , it's dead itself .

My search results show some people able to get their Nexus 5X work again by sent to LG to fix.
LG did not sell this model where I live and they said they do not have software to fix it. So I guess it's dead end for me? sigh..

its bricked. but why how,? but well. i think you must send it back for repair. i think i have hears people telling LG that while you were upgrading using LG bridge it didnt finished and i guess they should fix it. or unless you use service like JTAG but its called diferent i think.

I think I responded to your post in one of my threads. If you flashed an H850 firmware on to the H815 the phone is bricked. Only fix would be replacing the motherboard.

If you did flash wrong model firmware and the device shows no signs of life. Yes. Or an special box might can revive it which phone repair shops may have. But it wouldn’t be free

Please test this.
Switch Phone off, remove Battery and put back, do NOT switch on! Press and hold the Power-UP Button and connect Phone to Pc via USB. Keep the Power-UP Button pressed. Does the Phone show something ? Did it vibrated shortly too ?

If you have not triggered ARB it is possible to enforce the 9008 mode (by bridging 2 PINs) and recover:
