I tried with different drivers etc. but its just don't work, i downloaded TOOL ALL IN ONE, but this said that device was found but not said what or which device, only when phone is normally started i see it on the list of "adb devices" and in TOOL ALL IN ONE. Please help thanks in advance =)
Fastboot is an entirely different mode from adb, and as such it requires a different tool. In the console there is a command "fastboot", which is what you need to use to interact with the phone in fastboot mode. You can boot into fastboot mode from power off with the USB to computer plugged in by holding Volume Down, or it might be possible with TOOL ALL IN ONE, I haven't used it much.
Some basic commands:
fastboot flash unlock path/to/unlock.bin # This will flash the unlock bin
fastboot getvar unlocked # This will check if the device is unlocked
fastboot reboot # This will reboot the phone into normal mode, since powering off by holding the power button is a pain
To flash TWRP, there's a more advanced process with some specific requirements, but I'd be happy to share those if wanted.

First of all, which version of G6 do you have? The US997 one, or the H870?

H870
For H870 I'm not entirely sure, but I know that for the US997 you have to do a special procedure to make it permanent. Make sure you back up everything first, too.
With the phone in fastboot mode and a computer connected with fastboot installed and the twrp zip downloaded as "twrp.zip" (or whatever you want):
Make sure the bootloader is unlocked: fastboot getvar unlocked (should return "yes" or "true").
Flash the recovery: fastboot flash recovery twrp.zip (replace twrp.zip with the relative or absolute filepath/name).
Unplug the phone from the computer and reboot into recovery by holding Power and Volume Down. When the logo appears, lift your finger off the power button briefly and then continue pressing.
When you get to the factory reset menu hit yes twice, then the phone should boot into twrp (it may flash the LG logo, I've had different behavior on different phones. You won't need to hold the Power-Volume Down combo any more).
In twrp, swipe to allow modification, then in the Wipe menu select Format Data (and enter yes). This will wipe the phone, so make sure everything was backed up beforehand.
From the main menu go to the Reboot menu and select Recovery.
Here it might vary from the US997. Below are suggestions which I think are needed to have it work.
Download the no-verity-opt-encrypt zip, and connect the phone to the computer.
Once it's rebooted into recovery mode: adb push path/to/no-verity.zip /sdcard/
Then from the install menu in twrp install the zip.
Reboot into System from the reboot menu on the homescreen of twrp.
That should do it all.
I decided to update my old oneplus 2 to lineageos 15.1 with, but when I tried to flash the file with TWRP, it shows an error. Since the TWRP version I was using was old, I decided to update it first. Keep in mind at this point i had completely wiped my device. So, I downloaded the "twrp-3.2.1-0-kenzo.img" file, as per a youtube video where the dude managed to flash the update successfully, and gave it a go. It showed up as successful. Then i shut the whole device off, and tried to boot back in to recovery to flash the ROM again, but the thing won't boot. It's stuck on this boot screen (with the oneplus logo and 'powered by android' at the bottom), and refuses to go further. I'm stuck in a situation with the phone having no OS, no recovery and the thing won't show up when I connect it to the pc either. Well, the pc makes the 'device connected' notification sound when I plug it in, but nothing shows up on the file explorer or the device manager.
That's my dilemma, please i need help!
Thanks in advance.

You downloaded the KENZO (this is not oneplus2! ) TWRP and flashed it on another phone (oneplus2), just normal that it doesn't work and your phone is messed up.
If you can enter fastboot (vol up and power button to boot) you can rescue your phone:
-enter fastboot (vol up + power, while phone is completely off, u can also hold it until you can see "fastboot" written on the screen)
-connect device to a computer with fastboot installed
-type "fastboot oem unlock" into a terminal/cmd window if there is no error, you are good to go, otherwise your bootloader relocked, use this thread to recover
-if your bootloader is still unlocked, download the ONEPLUS2 TWRP IMG, ALWAYS make sure to only flash the roms, kernels, recoveries or zips for YOUR phone otherwise you can really DESTROY your phone!
-now type into terminal/cmd: "fastboot flash recovery *drag the oneplus2 twrp image into terminal/cmd window* and hit enter
-use vol down + power to reboot phone into recovery and wipe all partitions
-Install a ONEPLUS2 ROM of your choice
If something is not clear, use google, because this is most likely basic stuff you have to know when flashing your phone
I can in fact go to fastboot mode by holding the power+volume up keys. When I the phone to my pc it does show a fastboot device (9597b869 fastboot). What do i do from here?

i tried to follow the guide. but the bootloader, as per you description is relocked. the download link for the driver you provided shows up as empty/no longer available. that's where i'm getting stuck.
P.S, i can enter fastboot mode on the phone via power+volume up.
thanks for the help so far, i can't seem to find much help other than from you so far
Oh, the link is dead, sry for that. try this one (GDrive links are up and working).

so i managed to get into qualcomm mode, updated the drivers, and ran "MSM8994DownloadTool.exe" in administrator mode. it went as it's outlined in your guide. however, at the end of that process, the phone got stuck in a bootloop (the oneplus logo flashes for a moment and restarts). and can't get into qualcomm mode now, since when i connect the usb to the pc while the phone off, it lights the display (to show that it's charging, i think). any way back from this?
(i can still get into fastboot mode)

Do you still have TWRP? If yes go to TWRP and shut down the phone there, afterwards you should be able to enter qualcomm mode again.
otherwise you have to try (i think 10s power button will shut the device completely down). You should be able to enter qualcomm mode if the device is fully shut off (your scenario sounds as if the device is not fully shut off when u connect it to the pc).
Just to go sure: You are absolutely sure to have a oneplus2, are you?

nope. kept running into issue after issue, so got dejected and gave up.
I was having issues with the android 11 so thought to downgrade. Since the system wouldn't allow me to do it from the local storage, I thought I will just install TWRP and then flash the OS that way but in the process, I don't know what went wrong but fastboot will flash the recovery but when I tried to boot to it with the command it put me to Qualcomm crash dump mode. I downloaded the MSM Tool as I have gone through this process before but for the millionth time, I just can't put my phone to EDL mode. Every time I try with the volume up+volume down, keep pressing it until I plug the cable into it, the phone just goes to fastboot mode.
TL;DR - only have access to fastboot, no recovery, can't even install recovery because of crashdump issue. Phone not entering into EDL mode tried pushing it from fastboot to EDL using commands but doesn't work. Since it is at fastboot every time, device manager sees it as android bootloader platform. Device manager sees it as Qualcomm HS-USB Diagnostics 900E.
I've almost tried everything and I know device manager is supposed to see the device as 9008 for the MSM tool to work but it is NOT GOING INTO EDL MODE!!!!!
*sigh* any help will be really appreciated guys. Thank you.
[Thread Closed] Continue here.
I got a LG V20 H910 model and I cannot reboot the phone into the fastboot mode to get the device ID. I tried to do this on Windows and Linux and everytime I enter the adb reboot bootloader command, it will just reboot the phone but not into fastboot mode. I even tried to turn the phone off and tried booting it up by holding the power button + volume up and power button + volume down and it will still boot up normally.
Any help will be most appreciated.
follow the h910 root instructions, the bootloader doesn't actually get unlocked, instead the bootloader is replaced with a developer bootloader ** do a backup dump using LGUP even though the instructions say you don't have to!!(I ruined a phone by not)..... check antirollback too

Hello,
I guess I ****ed up big time.
My G6 is currently in the state of rebooting over and over again. Can't access EDL Mode through volume up.
I only manage to get to factory data reset, but it does not change anything.
My mess up:
I unlocked the bootloader with this guide just fine: https://forum.xda-developers.com/t/...urrently-supported-eu-h870-usa-us997.3614719/
Until step 9 everything was fine.
But using the factory reset trick to enter the TWRP 3.5.1 it just didnt work. The phone would boot into normal android.
I then rechecked the LG Unlock guide.
The command "fastboot flash boot boot.img" seemed familar.
Not realizing the difference between recovery and boot I used the command above to flash TWRP.
Now the phone only reboots. No chance to enter EDL mode (I see it poping up for a split second, then the phone switches to a normal boot).
No chance to boot into android to use adb commands.
I guess my only option is to try to open up the phone, shorting two points and use the following post to get into edl mode?
LG G6 TestPoints for EDL Mode (9008)
Simple af. Just short them. For incase that doesn't work;
forum.xda-developers.com
Or is there any possibility to recover it through the "factory data reset" menu?
Big thanks to anyone ready to provide some support!
EDIT: Nvm, sorry for "spam".
After trying over and over again I could get the phone into EDL mode. I then could fix the phone via LG Bridge. Will try my previous steps again with a older TWRP version (this seems to be the solution to my first problem)
