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 am rooted with s-off running on a ATT simcard but still can't boot in CWM recovery. In rom manager it says: current recovery Clockworkmode 3.0.2.4
Whenever I attempt to boot into recovery the MT4G comes up it reboots and it comes up agains and boots regularly. Any thoughts?
I followed all the instructions in this thread and am at the 85.xxx bootloader

I am bone stock other since I've not be able to get into recovery mode. Would a factory reset help?
Do it manually. Go to the bootloader and load recovery from there, or use adb and type adb reboot recovery.
adb does the same thing it attempts to get into recovery then goes blank and reboots regular and same thing with hboot.
Do you have fastboot on?
Nope. Fastboot is off. I can't even factory reset the phone. It just reboots like with everything else

most likely it feels as if the recovery image didn't take.
Code:
adb reboot bootloader
from there select "recovery" and see what boot loader you are using. If you have the engineering screen manually flash it.

1. Download CWR3. - link supplied above
2. Save to your Android SDK tools (c:\android-sdk-windows\tools) or platform-tools (c:\android-sdk-windows\platform-tools) folder and rename to recovery.img
3. Turn off your phone.
4. Hold the volume down button + power until you boot to a white screen.
5. Use the volume rocker to select FASTBOOT then press the power button to select it.
6. Connect your phone.
7. Open up a windows command prompt and navigate to your sdk tools or platform tools folder. tools (c:\android-sdk-windows\tools) or platform-tools (c:\android-sdk-windows\platform-tools)
8. Type
Code:
FASTBOOT DEVICES
to make sure your computer "sees" your phone and is ready to flash the recovery. You should get a serial number and then the word fastboot as the output.
9. Type
Code:
fastboot flash recovery recovery.img
and press enter. Give it a minute to do it's thing. You should get a message that says writing recovery and success.
10. Unplug your phone and use the volume rocker to select BOOTLOADER and then again to select RECOVERY and you should be booted into the orange menu of Clockwork Recovery 3

It says fastboot isn't a recognized command when I type FASTBOOT DEVICES
also for the bootloader part. It loads real quick and it says something about no image or wrong image in the lines of code that loads on the screen then disappears
Are you using Linux? If so, cd to platform-tools and use ./fastboot instead of fastboot. Otherwise try updating adb and see if it works. Also, the random text is the phone searching for PD15IMG or another restore image. Disregard that, unless you want to flash the stock unrooted image.
1.) You must have a full ZIP from ZTE
2.) Flash back the Original Recovery from the Original ZIP e.g. B08 B10 with ADB Fastboot command ( You must ticked OEM unlock on and USB debugging on in Developer Setting ) in Lineage.
2.1) push Power and tick restart in Bootloader.
2.2) go to Minimal ADB and Fastboot and type fastboot flash recovery recovery.img.
2.3) After this push with the Volume down recovery ,tick power.
OK! You can see the ORIGINALRecovery from ZTE.
3.) You must put a SD Card in Phone with the Original Update.zip
4.) Go in recovery and tick Update from SD card. Search the Update.zip and press Power.
5.) Wait until the Flash Process is finished.
6.) Tick Factory reset with Volume up/down push Power wait.
7.) Tick format Cache with Volume up / down push Power wait.
8.) Push Power to start your Phone with the Original Stock.
9.) After this you go to Settings / Build Number and Tick that seven Times to activate Developer Options, go back to setting and tick Developer Options ,here you must tick the OEM unlocking and USB debugging.
10.) Open Command window on PC and type "fastboot reboot bootloader" the phone shut down and restart in bootloader mode.
11.) in the Comand window you type" Fastboot oem lock" the Phone reboot and the bootloaer is locked. All your Data is lost in this Process!!![COLOR="Red"][/COLOR]

You made a mistake there as you have to enter "adb reboot bootloader" instead of fastboot. Other than that, it works perfectly. Thank you.

Did you find a solution to this? I'm running into the same problem with OEM unlocking being grayed out. I returned to stock just fine, but my problem is booting into the bootloader. Every time I try, it just goes to the "your device cannot be checked for corruption and will reboot in 5 seconds" screen. During this screen and during the screen that comes up you press the volume keys for the options menu, the fastboot oem lock command does not seem to work. Fastboot devices doesn't show any devices listed either

Seconded, I'm having the very same problem. Strange thing is, I cannot boot into booloader. I can boot into recovery, I can boot to system but whan I try to boot into bootloader via adb reboot bootloader, the phone just boots into system. If I try Power/Vol-Down, I will eventually land in FTM mode.
Anybody any clue?
SOLVED: After using the Windows based Axon7Toolkit which used Miflash to restore fastboot, I was able to boot into bootloader and also re-lock it.

You couldn't boot into bootloader because there was no bootloader mode. As soon as you update to a recent Nougat build (or an upcoming one) via official zips, your aboot.img will be changed and you won't have bootloader mode anymore. Axon7toolkit relies on fastboot, so it flashes a package through MiFlash that gets you fastboot support.
Jus sayin
Thanks for the clarification.
Is there an aboot.img I can flash e.g. via axon7tool so I can enable fastboot again?
Would that be counted as a warranty void by ZTE?

You can use the A2017U_FASTBOOT_UNLOCK_EDL from 4pda guys with MiFlash. Doesn't matter if you have a G, use this one
Actually axon7toolkit seems to flash that every time it does something related to fastboot. And after you lock it, you can install an official update zip (the latest one for example) and you'll get your phone totally stock, bootloader mode will be blocked.
Does this phone have? Is there a way to boot into such mode so I can flash something via fastboot?
Power and volume down keys just lead to some test mode. Holding the volume down while connecting USB does nothing as well.
I'm just having the same prob with --U51
Thanks
Not meaning to necrorez a thread as the entire forum section is inactive...
On Y625-U21 the best way to enter fastboot mode is via adb:
- activate usb debug
- use "adb reboot bootloader"
you are now in fastboot mode. Notice that on the phone you won't see a special screen: just the huawei logo like it's stuck, but you can use fastboot to do what you want (unlock the bootloader since it won't require codes, run TWRP, flash TWRP etc etc...)
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?

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?

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?

Hey guys, I've been trying to unlock my bootloader so that I can try and root my Maven 3 via Magisk. The problem is, I can't get into the bootloader. If I try to reboot to the bootloader from recovery mode, it just restarts like normal. Same thing when I try using adb commands in the cmd prompt. I am on Windows 7.
I think it could be unlocked trought EDL mode. But we need some expert help

is just boots into the android system.
Any clue on what to do?
I have the same question - bootloader mode will not load when I issue "adb reboot bootloader", nor will it go into bootloader when I go into recovery mode (via POWER + VOLUME UP) and then I choose the "Bootloader" option. The phone just boots into the system. When I use "adb reboot recovery" it does go into recovery mode, and I am able to get a shell and copy files via adb just fine. I am using the latest platform-tools.
This is a ZTE Z835 (Maven 3), AT&T, carrier unlocked phone.
I don't think there is a bootloader... I have not found any fastboot-compatible mode on this device nor have I heard anyone else find one. You have FTM mode (Power + Volume Down) and EDL mode (adb reboot edl). EDL mode lets it work with QFIL, and with QFIL, you can literally dump and modify any partition on the device you want... I'm not sure what else you want. There's a new method for unlocking the bootloader https://www.xda-developers.com/unlock-bootloader-zte-phones/. I found that my devinfo partition was already unlocked, but you may need to check. I'm going to try and figure out how to create a recovery.bin partition able to be flashed in QFIL.
