After installing CM13 (coming from 20H stock 4.4.2 firmware) I somehow ended up in the hard-brick Qualcomm HS-USB QDLoader 9008 mode.
I fixed this using these steps: http://forum.xda-developers.com/showthread.php?t=2582142 writing that old 2.6.3.2 TWRP and other .bin files extracted from the .kdz
Phone boots OK into CM13 now, but when I try to get into recovery (either using Power+Vol Down or through Advanced Reboot in CM) I get the error:
Secure booting error
Error: Boot Certification Verify!

Does anyone know how I can fix this, and flash TWRP? Tried TWRP Manager, Flashify etc, but they all give a flashing error. All fixes for this which I have found online seem to be for people who are running a stock ROM.
(I know going into download mode and returning to stock again etc will sort this, but surely that's not necessary?)

Unclear of phone history.
Phone model: D803 Canadian
Current issue:
Can NOT go to download mode.
CAN go to TWRP mode ver 2.8.4.0 installed by pressing VOL + and VOL - and Power button, all 3!. Shows some chineese characters first before going into TWRP.
I am NOT able to flash custom roms (tried cm12-d803, aicp-kk-d803) I get assert failed: run_program("/system/bin/loki.s h") == 0
I have tried the instructions here http://forum.xda-developers.com/showthread.php?t=2620733 [[SOLUTION] LG G2 VS98012b Problems With Loki (loki.sh) + [ROM][UNOFFICIAL]CM10.2], but no go..
How can I fix this?

Did you tryed to cleanflash? Btw why is your download mode missing
It shows chinese characters before going to twrp. I don't get it why it is like that
Does it show the chinese characters and then boots into twrp? If so maybe try to flash also later 2.8.4.0 recovery from blastagator.
Try to google the right rom for the D803 Canadian version cause I've read that some D803 models need to flash roms from another model instead.

Well maybe outdated loki or yeah I can't tell you the truth exactly, Ehhm... Maybe you have to flash the bootloader files again? Try to find bootloader files for your phone in a flashable zip. Maybe that works
First try to find alternative things before what I said about the bootloader, cause flashing the wrong things can harm it.

FIXED!
I borked it further by trying to install older recovery using dd command while in TWRP. Ended up with secure boot error ONLY when I try to press all three buttons, and then I get QDLOAD_BULK in device manager. Device continues to boot normally if I press the power button.
Tried to use http://forum.xda-developers.com/showthread.php?t=2582142 [FIX] NO Recovery mode, No download mode, after OTA on rooted LG G2, but wouldn't work in Ubuntu. Drives kept disappearing after showing up momentarily. NOT the case in Windows. So used http://forum.xda-developers.com/lg-g2/general/unbrick-lg-g2-qhsusbbulkqualcomm-9006-t2939627 Windows application, and selected D802, it failed on a few items, but gave me download mode and Security Error on normal boot.
Used LG Flash tool KDZ flasher to flash v20 Rogers, but failed at 40%. Tried again, still failed.
Used LG TOT Flash tool, and was successful!
@SaHiLzZ Nice that you fixed your problem on your own:good: Have fun further with it:laugh:
Hi. I have a big problem. After flashing modded rom i get an error. After reboot i have Security Error and bootloop. Computer don't recognize phone. I can't also go into download mode or recovery. Fix solution with ubuntu don't work because ubuntu see only sda partitions. Can anyone help me with this?
Hi guys, I might need some help or a walk through here, I might have bricked my phone. I stump-rooted my phone ( 4.4.2) and installed TWRP Recovery 2.8.1 initially , Installing SuperSU which patched my sdcard and rebooted causing my phone to get stuck in a boot loop giving me no access to download mode, just recovery. From there I tried to install Cynogen mod 12 in TWRP recovery to fix the bootloop but any attempt at flashing gave me an error "error executing updater binary in zip." So I extracted the folders and flashed the 2.7.0 recovery.img which sayed it worked but now my phone is still stuck in boot loop, no download mode and when I try to enter recovery I get stuck in fastboot mode with port change errors. I took some screenshots so it would be easier to help me out. Every time I plug in the USB I get the following errors, the screenshot is from continuous attempts
I have the mini sdk installed and Koush drivers. Device manager does not recognize my phone anymore but it does come up under Fastboot Interface
Any Help would be greatly Appreciated
Because I'm a new member I can't post screenshots so just add an h infront of the links.
Thanks in advance for all your help

Can you please explain how to do that WITHOUT entering download mode?
Maybe LG Flash recognizes your phone and will do the job.
LG Flash does not recognize my phone at all. http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 Do you think this method will work?
I once bricked my phone by installing a L01F ROM on my phone by accident, and had to manually reflash every partition in windows CMD prompt. I have been using my phone fine since I recovered from the brick but I was going to tot to stock and update to lollipop but my download mode says secure boot error and shows up as qhsusb_bulk in device manager and gives me a ton of partitions. I have been looking around for a solution but cannot find one. The only thing that is broke is my download mode. I have recovery and a booting ROM.

I have flashed a new laf.IMG but I still get the secure boot failure, boot certification error.
Repaired using skr tools. Wonderful set of tools
While flashing pixel experience plus rom, the device did not boot up correctly causing a google loading screen which did not change even after an hour. At that time i realised that the rom didn’t flash correctly, or the rom might have some faults. So I rebooted my mobile in custom recovery mode to flash the stock rom, but it did not complete the flash, it generated error 7. So I tried to install havoc rom and I encountered the same problem. Not just that I have tried installing at least 5 rom which gives me the same problem. I can’t even flash my recovery rom. It generates the same errors which include error 7 and invalid zip file. So I tried solving this problem by unzip the rom and editing the assert script and re zipping the file, and I encounter the same errors. I have even tried using a different custom recovery like TWRP and red wolf (latest updated version), but I face the same errors. The mobile has no os installed and it doesn’t allow me to install any rom. It only allows me to install stock recovery and other custom recovery by using Fastboot mode. I have tried add sideload through the custom recovery and the mobile gets detected, but it gives the same errors.
So I tried using QFIL application as the mobile was a Qualcomm device. The mobile gets detected as 9008. And I tried to download the program files on the mobile, but then it gives me a Sahara fail error.
I have tried to do it multiple times and I end up getting the same error.
The device has a unlocked boot loader but it was never rooted.
Please help me.
Can’t post it in the developer forum for this device as I don’t meet the requirements for posting it

1. 1st try to flash fastboot rom,
after install fastboot rom if the phone stuck on asus logo or any other error then
2.Try to install Qfll file (select ww_no_fsg.xml file) after successful installation , boot your phone.
3. again connect your phone fastboot mode and flash fastboot rom
If every installation is successfully done then i am sure that your phone is boot properly in stock rom with lock bootloader.
because I faced same issue,
remember 1st try to install stock fastboot rom and then try to flash Qfil files
Wish you good luck :good:
Try flashing fw063 before flashing your custom rom.(that fixed for me)
if it didn't work try this (rooted):-
