I just asked because the logs show that your LAF partition isn't flashing and from what I've been reading so far about the LAF partition is that it is a very fragile thing.
Have you tried a factory kdz with LGUP?

what a amazing ! i got another‘s help,now i can boot into the twrp,
but after i install the AospExtended, it just play the aex booting video,how many times i erase all date include system and date,cache,etc.
now ,iwant to konw how to get it into a system

Find stock.kdz to flash using LGUP, reflash TWRP using fast boot commands. Should boot correctly after stock .kdz is applied. Once confirmed your phone works correctly.. Boot into TWRP factory reset, and wipe partition, then attempt to flash your choice of custom ROM.

My friend,this is no hard brick.sometimes this error happens because because your recovery.img file is corrupted.Check that your recovery.img is found in the cmd folder...And use command 'fastboot boot recovery.img' << this one surely will work.Otherwise,please follow my own thread where I faced an identical problem..>>http://forum.xda-developers.com/lenovo-a6000/help/problem-flashing-rom-soft-brick-t3353665 Oh,and calm down, not that serious of a problem,you wont have to go to the dreaded service center.

When you can't even enter to bootloader (or fastboot), that situation is called hard brick. The problem you are facing is due to the wrong recovery version. Try this latest twrp 3.0.2 by sevenmax.
And yah, if "fastboot flash recovery recovery.img" doesn't work, then try "fastboot boot recovery.img"

This method alsi not gud. Try this method.
https://boycracked.com/2016/02/12/e...rmware-any-android-devices-via-fastboot-mode/
I did it & saved from hardbrick. Just do whatever files u have. But dont forget ti erase boot. Erase boot then flash boot* this is main step. Then flash twrp and instll any backup or new rom.
Follow these instruction.... main files are in stock firmware file. Recovery alone flash ur own custom recovery of ur choice

Bhai, This method is for soft- bricked device, when you can enter bootloader.
In case of hard brick you can' t even enter in bootloader, and can't run these commands. The link I posted is for hard bricked devices.
And, you don't actually need to go through these complicated steps in case of soft brick.
Just flash any recovery through bootloader and then flash any ROM. You don't need to extract and flash each file separately.

[HELP] Bricked LG G6 US997, Need help

Hey everyone, I just bricked my LG G6. I was trying to use Uppercut and LGUP to flash a stock firmware, but it wouldn't detect my phone, so i followed this post: https://forum.xda-developers.com/showpost.php?p=70446385&postcount=70
Once I did that and restarted my phone, it got stuck in bootloop and it will display this: "Your device has failed routine safety check and will not boot."
Right now, I can only access fastboot and download mode, but download mode doesn't stick and my PC doesn't detect the phone in download mode, only Fastboot. I can't enter recovery.
Please help guys I don't want my phone to be scrap metal
P.S.: Was running LineageOS prior to bootloop.
Have you tried flashing anything from fastboot?
If you phone has bootloader unlocked then flash twrp via fastboot. If not contact LG for a service
---------- Post added at 07:00 AM ---------- Previous post was at 06:59 AM ----------
Also wiping misc is a very bad idea

No I did not. Should I? I bricked my HTC One once doing this and I remember locking bootloader would make things harder to fix for me.
Sometimes getting the phone detected in download mode can be tricky, often you will have to play around with different usb cables and / or computers.
I would try flashing TWRP in fastboot. See if you can get into TWRP, then you can try flashing a rom.

I don't really have lots of USB cables or computers at my disposal though.. Do I just keep trying until it works, and even if so, how do I know when the phone is detected in download mode?
I also found out that even though I can enter fastboot, my bootloader is somehow locked again, and I can't flash the unlock bin so I can't even get a custom recovery to be flashed on there. Any other ideas or is my phone dead for good?
New update:
- I entered fastboot and tried flashing TWRP but bootloader is locked. Tried to flash unlock bin but i get this:
target reported max download size of 536870912 bytes

maybe you locked the bootloader at some point with twrp !
maybe your unlock.bin is corrupted you need either unlock bootloader or try to flash kdz via download mode accessing
if you can't do that, LG center is the only way good luck
Why were you originally trying to flash stock firmware?

Click to expand...

I realized the visual appeal of custom OSes no longer attract me as much as full usability (Using google pay or fingerprint in some apps) and stability as I used to when I was young. I wanted to flash stock firmware and just keep root and xposed to enhance my stock experience.
Update 2:
I contacted LG and they quoted me a minimum of $300 and up for repairs.. Really hope someone has a fix to my issue or any other suggestions. I'm thinking about taking to a phone repair store but I doubt they will be able to fix this. I live in Houston, TX area if anybody has store suggestions. Thank you
So what rom were you on? And how did you flash it without TWRP? Can you go through from start to finish exactly what you did?

No relock anything. No risk to hard brick. If you flash down to 711 and then OTA update,it will. No need adb and fastboot install. Install usb and motorola driver
thanks for the quick answer. no relock, so if something go wrong i would still be able to flash some custom and rsolve the issue , right ?

+1 facing the same problem... Recently I found out it might be a port issue or a cable issue so i tried using my old laptop. Although it showed sending ok, writing ok but when i tried to get into recovery, it was the stock recovery. Try changing cables or using usb 2.0 ports. I didn't work for me but might work for you.
If possible please let me know how it went.
I have a bit different issue here
My phone is officially unlocked and updated to stock Pie 053
When I flash twrp via fastboot, it doesn't do anything, only blinking cursor
When I press ctrl+C to cancel it and reboot, it is still stock recovery

Is your CPU ryzen? If yes try it with another Intel CPU PC,and make sure you are enabled USB debugging in developer option and use USB 2.0 cable and port.
