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..

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.

I have tried couple of D803 roms, CM12, AICP KK.. they fail with the assert error for loki.
How to fix this. I am on 2.8.4.0 TWRP version.

Well maybe outdated loki or yeah I can't tell you the truth exactly, Ehhm...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:

LG G2 Bootloop Bricked - No recovery or Download mode

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?

D800 broken download mode

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.

[SOLVED] [Loop] Your device is corrupt it cannot be trusted and will not boot

Hello,
I have an issue with my brand new G6.
It is in a loop "Your device is corrupt it cannot be trusted and will not boot" , no more recovery available.
What i did:
I unlocked the bootloader and flashed Magisk via TWRP the device displayed that the partition was corrupt and need to be erased.
After that the device was in a loop to twrp, whatever the wipe or ... no system boot.
I read that i had to format the data partition so i adapted a what i found here to my available partitions
https://forum.xda-developers.com/tmobile-lg-g3/general/fix-recovery-loop-twrp-computer-t2873386
the device is now in a constant loop.
Does someone can help me please ?
is there any way to recover it ? download mode ? how ?
Update : I succeed to boot into download mode but LGUP gives me an error while trying to flash
error 0x2000 ... ... cefs::initialize()

Can you boot to TWRP?
Did you make a backup and have access to it? Especially the EFS partition? If you do, restore the EFS partition.
If you can boot to TWRP, try the following:
- wipe everything (the option where you have to type 'yes').
- download lineageOS and flash it. If this is working fine, install whatever ROM you want to install.

no access to twrp anymore , no backup , only access to download mode now
is there a way to flash back twrp or stock recovery from download mode ? boot into fastboot ?
(i know... i have no excuses , but made that so many times without issues ...)
thank you in advance

Maybe you should go in download mode and flash stock Rom with LGUP.

LGUP gives me an error while trying to flash the rom error 0x2000 ... ... cefs::initialize()

Can you flash twrp through lgup or fastboot?

For those that could be in the same situation i finally succeed to flash with LGUP last version but without the 8894DLL
the error was probably coming from the dll.
Cheers and thanks all for the answers

It's probably a problem with the DLL, try to extract it from the kdz and input it in Lgup folder (I don't remember where and I'm not home, check the main thread for that) and after that retry flashing
EDIT : well you were faster than my phone glad it worked for you.
