Hello.
Move your battery, then replace it.
Flash an official kdz from lg.com with LGflashTool and your phone will restart
Your device is Brick!!
Try to enter Download mode
Flash your device again with LG FLash tools(tot File) or KDZ

I was trying to install TWRP on my LG G3 (D850) and somehow got it so it would only show up as a Qualcomm HS-USB QDLoader9008 Device on my pc with no screen on and no way to get to any DL Mode.
I followed the directions from http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/ and used the LG Smart Boot Diagnosis Tool (1.3.1) to get it back to be able to boot but as soon as I run the LG Flash Tool again and it resets I'm back to the no screen and only being identified as a "Qualcomm HS-USB QDLoader9008 " device via USB. I have done this 3 times now and still getting the same result. I rerun the Anti RollBack software and then try to flash again but it always does the same thing.
Is there something I am missing?
Thanks
LG F460S is bricked with HS-USB 9008 mode due to wrong firmware flashing. After using Memory card trick given here, It caused boot loop with secure boot error , boot verification failed as in attachment.
Any help???

Try Extracting laf.img and any other file that matches with ls991 recovery zip from f500l kdz file and then you would be able to flash the original files with fastboot but before that make sure you are on h811 10n firmware because thats the only rom which works with this fix
ive been on the same boat with you just until i found the fix
and never try to unlock the bootloader because f500 is factory locked and you cant flash anything that contains boot.img
just use the phone normally with 5.1 and never get curious about updating:good:
i've flash laf.img of F500L, Windows not appear driver on Devices Menager when I enter to Download Mode. you can teach me or chat with me? shamescool
Mine is H815 with F500L motherboard,but in my case i cant even get in qhsusb 9008 mode,how did you get to that?

Hi Friend..!
Have You Find Any Solution....? I am in same condition when flash f500l Recovery and put mobile in download mode there is no driver loaded in Device Manager and LG UP don't detect any device attached.
Model Written On Backside : H810
Model Written On Board : F500L
Hey everyone
My LG G4 (H815) suddenly turned off when i was using it, and it showed no life when i tried to boot it up again. Its completely stock, no custom recovery or custom firmware is installed. I cant boot into fastboot or EDL mode. I tried the button combinations as well as the test point method but i just cant get it to enter any kind of recovery mode, the screen just remains black (no backlight either). I installed the Qualcomm HS-USB drivers and when i plug my phone in my pc it gets recognized by QFIL. I tried flashing the fimware but it always gives me the Sahara unable to read packet header error. Can anyone help me?
Thanks in advance.
Have you searched the forum and tried any of these ?
