You are seeing the LP fastboot brick. You'll have to short the motherboard and invoke either bulk (9006) or Qdloader (9008), either of which are fixable.
 
thank you for reply
could you explain more....
do you mean that there is hardware pb and i have to change the motherboard

You don't have to replace the board, you short a specific set of capacitors as shown here:
http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404

That allows you to obtain bulk mode (qhsusb_bulk 9006). You can then fix it using linux as shown here:
http://forum.xda-developers.com/showthread.php?t=2582142

(If instead of getting bulk 9006 mode, you get qdloader 9008 when shorting the mobo, then let me know and I can provide alternative instructions.)

Or you can try the windows solution here:
http://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076

I would recommend once you have bulk mode to flash aboot, boot, dbi, laf, rpm, sbl1, and tz regardless of what the above guides might say. This will restore download mode at which point you can flash a kdz or tot to completely restore the phone to working condition. Here are the partitions you'll need for the g2:

Good luck.

Look like I have a very similar problem with my g2 d802. Can you explain exactly whats steps you follow? did you short the capacitors? or is there a way without messing with the hardware?

Thanks in advance.

How exactly is your device showing up in windows device manager when plugged into the PC?
 
I fixed my problem on d800 by shorting the capacitors. Didnot get the qhs_usb qloader 9008 the very first time. But got it after driver update. I was on Windows 8.1 though. Don't know about win7. So, after getting qloader 9008 i extracted the kitkat .tot which i downloaded from http://forum.xda-developers.com/showthread.php?t=2663369 then flashed the recovery partiions to get back my download mode. Then flashed the tot using lg flash tool.

Ok so you have no choice but to short the capacitors. If you continue to get 9008 mode,
follow the picture instructions here:
http://forum.xda-developers.com/lg-g2/general/fix-unbrick-lg-g2-stuck-qualcomm-hs-usb-t2933830

However don't use the board diag tool posted there. Instead use this one:
https://mega.co.nz/#!pZQyXbAD!960ZDwH36ZwqY2C7CoiDdfgxCRodU2VPFMaAGkobtCc

Use the .exe inside 3.99c variant 2.

Hi Hi Hi :)

Thank you for your help

It did work for me after some persistence, I shortcut the capacitors to get the "Qdloader (9008)"
Capture;;;.JPG

first I have had an error popup saying "device was not found in dload trying flash programmer" >> see next picture ,then I found an answer in this thread http://forum.xda-developers.com/lg-...k-lg-g2-stuck-qualcomm-hs-usb-t2933830/page51
error.JPG

I had to use (BoardDiag3.99c)as you can see in the firs picture instead of the one you have provided me with , but I am not sure of this because even this version did not work the first time.

anyway now my phone is working, I still need to try to restore the emei and network (because I am flashing a D801 firmware to a LS980 motherboard) ,,,,, , I will come back to you whenever I break it :3

Thank you
 
i am doing same but board diag given by you is giving same error " device was not found in dload trying flash programmer". and board diag used by kamel kgb3 gives this error

Can honestly say i've never seen a g2 reported that way in device manager. But yeah if you have no download mode, no boot, no twrp and you're stuck in fastboot mode where it's not processing your commands into an action, then you'll need to short the capacitors to move forward. At that point it's just a matter of whether you invoke 9006 or 9008. Both can be fixed.
