2017G can´t boot into recovery

Hy,
i,m on 2017G B03
Just tried to install the original twrp version. Now my phone doesnt boot into recovery but still boots rom. I´m also not able to boot into edl.
Any ideas?
Yours

If your phone is rooted, you can use flashify to install the newest TWRP.
Otherwise booting into edl by either "adb reboot edl" or pressing (volume up + volume down + power) should work otherwise your phone is broken.
Last Option would be to boot into fastboot ("adb reboot fastboot") and flash via "fastboot flash recovery twrp.img" (please note that your bootloader needs to be unlocked for this operation)

Flahify worked!
Thank you

What happens when you boot your device, enable usb debugging, connect it to your pc, open up a command window in the folder where you downloaded adb and enter the command "adb reboot edl"? What does it say?
Try restarting your adb server with "adb kill-server" followed by "adb start-server" and then retry the "adb reboot edl" command.
Also try to kill the "adb.exe" process in task manager before trying again.
Alternatively, you can try powering the phone off, and then holding both volume buttons while connecting it via USB. Some users manage to get to EDL this way, but personally I get DFU mode.
If you manage to get the phone in EDL mode, try restoring the stock recovery backup you made with the axon7tool and then reflashing TWRP. One user reported this fixed his similar issue.
EDIT: Too late Wonderful to see everyone helping each other so quickly.

When my phone is in fastboot I don't see it on cmd "adb devices".

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.

Yeah, so I wanted to flash TWRP but it doesen't seem to work i did what was said in many guides but maybe if you tell me how to do it, it will work =) Thanks
So i tried to flash TWRP with the TOOL ALL IN ONE, everything was okey but then error happened called "Unknown device"

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.

Cannot reboot to bootloader, how to do it? A2017G

Hi,
I cannot boot to bootloader (A2017G), using the hardware buttons I can get to recovery and select the reboot to bootloader option but the phone restarts normally and does not go to bootloader.
Using ADB, if I issue the command "adb reboot bootloader" the device restarts normally and does not go to bootloader, if I use "adb reboot recovery" the device boots to recovery, from there I select reboot to bootloader and again it does not work.
If I use the Axon7Toolkit to unlock bootloader, the adb test works, fastboot test does not as per above. If I proceed to unlokc bootloader anyway, FASTBOOT_UNLOCK_EDL_N is seemingly successfully flashed, it displays "success" in MiFlash at least. From there I press button to continue, and unsurprisingly it says "Fastboot device is not connected", and then I can again only boot normally and not to bootloader.
What am I doing wrong?
Thanks,
Jon.

OK, not sure why as I did the exact same thing that I did numerous times previously, but it has now booted to fastboot and I have been able to unlock the bootloader! Now for the ROM...

Back to stock, relock bootloader problem waiting for device

Hi,
i used Miflash in edl mode to get back to stock rom. after flash and reboot I used the recovery mode to do a factory reset.
It seems to work. It shows Android Recovery, but the bootloader is still unlocked.
What mode do I need to enter to use the "fastboot oem lock" command? I always see "waiting for device" and nothing happens
When I type "adb devices" I can see the phone. I saw there is a command "fastboot devices", too. but it shows me no result.

Then, try to use fastboot cmd

Thanks, before I can try that I have to solve another problem.

That doesn't work. The phone isn't entering a special mode. I can choose fastboot from the bootmenu, too. But nothing happens. The phone does a restart, shows the bootmenu again and boots android after 5 seconds.

@Stevie123
You need to enable fastboot (bootloader) mode since it is disabled by ZTE, so that the selection from menu to be effective (after enabling it, in fastboot mode, your command "fastboot devices" (to check) and "fastboot oem lock" (to lock bootloader) will be accepted).
You can use Axon 7 EDL tool to unlock the bootloader.

It's already unlocked. I have to make another unlock procedure again to get access to fastboot? The EDL Tool tells me that I have to wipe and reset the phone after it. So it seems I can't keep my data and just lock the bootloader.

Either Lock or Unlock will wipe your data. And yes, the unlock procedure by Axon 7 EDL tool includes the enabling of fastboot. So you have to re-unlock if you want to relock.

I think this EDL tool doesn't work very good. It flashed something to make fastboot available, but I had a green ZTE Logo screen and this screen also had errors like white spots. The original ZTE logo is in cyan. But the fastboot worked and I could lock the phone. But I couldn't do anything else anymore. I couldn't reach Android and reflashing also didn't work. So I tried to use the EDL Tool to unlock my bootloader again. It said success, but it didn't work. It was still locked.
Well, I had to wait until the phone was empty. Luckily I could reach EDL Mode again. I used the MiFlash again to Downgrade to Android Nougat B12. I read somewhere that the fastboot is included there. So I had the right ZTE Logo back and it worked. I could leave the Bootloader locked. The final update I did with a SD Card to the lastest Android Software for Axon 7. Luckily without a brick. It's a pity that they don't offer any Updates anymore.

Reboot to Recovery Loop but no Recovery Installed - How to get back to System reboot?

I tried flashing a recovery program (TWRP) in fastboot mode. The powershell said it was successful, but now the phone cannot get past the bootloader unlocked screen. It started to System twice, and I made sure to remove the security PIN and enable ADB debugging on this computer automatically. However, "fastboot devices" and "abd devices" commands do not return the device ID, but the phone does turn on when I attached the USB cable that's connected to my computer. I think it's trying to restart into recovery mode, but the recovery program (TWRP) did not install correctly. How can I get it to reboot to system again?

When I try to give a fastboot command, the powershell just returns
<waiting for device>
and then nothing happens.
