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.
US996 Unlocked, stock rom. I was in XDA Forums and saw there were app updates, one being Play Store. I updated. When I tried to get into Play Store, the message "this version of play store is incompatible with your device, go to settings and disable app update (or something like that). I tried but the app was not listed in settings. I tried to reboot and now the phone bootloops. All I can get is the warning that the software cannot be checked for corruption and then a quick display of the LG logo, then screen off, and then LG logo again and then warning screen, etc. If I try to reboot into recovery I get the Factory data reset screens and I answer both "yes" and the phone goes into adb mode.. From adb mode I can fastboot reboot, which puts me back into the above loop, or fastboot bootloader, which merely returns me to the adb screen. What can I do now?
Maybe try relocking the bootloader. I am pretty sure (someone correct me if I am wrong) that that pop-up of the "cannot check for corruption" usually only shows when the bootloader is unlocked.

Do you have fastboot installed on your computer? (Something you would have had to have intentionally installed) If not google Minimal Fastboot /ADB and install it, enter the supposed ADB screen you are talking about and see if it makes contact with your phone.

I have the fastboot on the PC that I used to unlock the bootloader.. I enter fastboot on the PC via the administrative command prompt. With the phone in the fastboot mode, I type "fastboot devices" on the PC and get a proper response (LGUS996ab**** fastboot). If I enter ""fastboot reboot" I get the bootloop. If I enter "fastboot bootloader" I wind up in Fastboot Mode on the phone again. I was hoping there was a "fastboot recovery" command but there doesn't seem to be. I don't know what to do next. I am not all that familiar with what can be done from fastboot. My only experience with it was when I unlocked the phone. I am desperate!
Okay, so if you do not have TWRP installed on your phone, then I don't know if you can save your data. You can try to
Code:
fastboot erase cache
and see if it helps, or if not and just reset the device fastboot oem lock I think. Maybe ask around in the unlocking help threads or perhaps someone with more knowledge will chime in. If none of this works, then there are some instructions on how to get your phone back to stock in the News and Guides section.
EDIT: Maybe try the power+volume down. It may work? I have tried it and never got it to successfully work. But you can try it.

Thanks for your help. I DO have TWRP installed and have used it often for backups. But now the only way I know to TRY to get to it is by the power/vol down until LG logo, then release/repress power button sequence but this just gets me into fastboot mode. II have some recent backups saved on my micro SD card - is there any way to flash one of them through fastboot if I load one onto the PC?
Yeah. My bad. Okay, so how I get into TWRP is through the EasyRecowvery.
Go ahead and download it from Git-Hub (1.3b3).
Now extract it and run the cmd program. Enter 5. which is extras and stuff and then enter 5 again in the sub menu which will let you boot into recovery. When you are in recovery, and plugged into your computer, you should be able to either flash or drag and drop like a flash drive on the the phone. Hope that helps a little bit.

Since you are only rebooting into recovery and not flashing anything it might. If not, it will just fail and not harm anything. Last thing to try is the
Code:
adb reboot recovery
which is the only thing I can think of and I think you already tried it. Otherwise you will need to just go stock.
I installed Android O DP2 update via OTA yesterday. The phone updated, rebooted to the new build and restarted abruptly and since then has been stuck in a boot loop. The Google logo shows up, goes to the android animation step and then Google logo appears again.
I don't have bootloader unlocked, don't have TWRP and have done OTA updates. I am able to get into the stock recovery mode.
How do I fix this, i.e. make it work in any way without erasing the user data? I don't mind extreme steps (without erasing user data) because I was planning to reflash 7 with unlocking & rooting today.
Try to wipe cache from recovery - in recovery hold volume-down and select "Wipe cache partition". Should do the trick
I tried, didn't work. Had to factory reset in the end. Also opted out of beta
I just read that some people that took the update from certain builds had boot loops due to the update only replacing part of the OS but leaving the 7.x.x system in place causing it to boot loop. I think it was like on android authority or something like that.

To flash a system image:
Download the latest system image for your Nexus 6p, then unzip it to a safe directory.
https://dl.google.com/dl/android/aosp/angler-n2g47o-factory-dc258043.zip
or Download any of your choice from here
https://developers.google.com/android/images
Connect your device to your computer over USB.
Start the device in fastboot mode with one of the following methods:
adb tool
http://developer.android.com/tools/help/adb.html
Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device.
POWER BUTTON + VOLUME DOWN BUTTON
Click to expand...
Click to collapse
If necessary, unlock the device's bootloader using one of the following methods:
Code:
fastboot flashing unlock
If you are updating an older device, run this command:
Code:
fastboot oem unlock
The target device will show you a confirmation screen. (This erases all data on the target device.)
Open a terminal and navigate to the unzipped system image directory or Open a command prompt from within your System image folder (navigate to where you have flash-all.bat located on your PC, shift + right click anywhere within that folder, select open command prompt here
Execute the flash-all script.
Code:
fastboot flash-all.bat
This script installs the necessary bootloader, baseband firmware(s), and operating system.
Once the script finishes, your device reboots. You should now lock the bootloader for security:
Start the device in fastboot mode again, as described above.
Execute:
Code:
fastboot flashing lock
or, for older devices, run:
Code:
fastboot oem lock
Locking bootloader will wipe the data on some devices. After locking the bootloader, if you want to flash the device again, you must run fastboot oem unlock again, which will wipe the data.

Thanks for your reply..But you can only do this only if you have an unlocked bootloader and debugged mode on. I didn't have either so it won't allow to flash with locked bootloader.

To unlock you first need to have ticked the allow OEM unlock from developer menu within the OS. It won't work otherwise.

If your touch screen isn't working, it might be related to the Android O Beta you flashed. Can you boot the phone up? If you have an OTG cable, connect a mouse to your phone. Turn on OEM unlocking in developer options. Do a factory reset.

Hi.
Recently I decided to flash lineage os 15.1 on my MiA1
For that I have downgrade to Android nougat.
After downgrading I booted my device.
After setting up device I booted device in fastboot mode to follow further steps like flashing TWRP and all but the problem is my device goes in fastboot mode and it is not identified by abd and after that it is automatically getting restarted and is not holding in fastboot mode.
Please help??
Odd issue. What are you using to flash? If you are using XiaoMiFlash.exe, you'll want to try the (THIS WILL REMOVE ALL YOUR DATA) "clean all" option. Please note that this removes all your data.
I have used MiFlash tool for this and now My device automatically reboot from fastboot mode so I am not able to use adb as well to flash rom or twrp also Now MiFlash tool is not recognising the device.

It should boot if you've fully flashed it and cleaned the user data partition. If it still isn't, you'll want to wait for other members with more experience in bricks to chime in.

My device is booting up without any problems.
But the problem is bootloader is still unlocked. So i am not able to update via OTA.
And as the device does not holds in fastboot mode so I am not able to do other flash work.

Is there any way I can share a video of my problem with you?

Oh. If it's booting up fine, then you shouldn't be worried too much.
If it keeps restarting in Fastboot mode, it could be a driver issue which is preventing your PC from recognizing your device and vice versa. I'm on Windows 10 which installs drivers automatically so I've never had experience with it.

Please see this video.
If i boot in fastboot mode the device should be in fastboot mode till power button is not pressed for at least 10 seconds.
But in this case it gets switched off.
I have not connected the USB to pc and nothing else.

I think that's expected behavior? If it doesn't recognize itself being connected to a device, it'll exit fastboot mode.
I think you need to connect it to the USB cable and into your PC for it to not restart/power off.

No when I connect it to pc at that time also same happens.
Previously when booted in fastboot mode it will stay ther by the time juice is out.

So do you know how can I help myself out?
wait.. what exacly did you do when you booted into fastboot? did you type "adb devices" or "fastboot devices"? also, try rebooting into fastboot mode by typing "adb reboot bootloader" in cmd, with your phone plugged into your pc, and with the proper platform-tools installed. it shouldn't really go away from fastboot mode like that.

Hy man, I know basic of adb and I use cmd "adb devices"
My device is recognised when it is on.
I can also give various cmd like boot in recovery or fastboot mode or reboot and the device follow the instructions.
Please see the video that I've shared.
Once fastboot mode is on the device is automatically restarted in about 10 to 15 sec and within this time MiFlash tool or adb cmd prompt bot does not recognise my device.
I have tried to flash OTA via adb side load but it is showing error.
Help me with your input!

Your device doesn't get detected in your CMD prompt when it's in fastboot AND you type "fastboot devices"?
If it doesnt then you might have flashed something incorrectly.
Also, make sure to have your android drivers up to date in your pc. It's very, very likely that you don't have them installed on your PC, or they are outdated. See this: https://developer.android.com/studio/run/oem-usb.html

I have faced this issue. Yesterday i dirty flashed a custom rom. but i forgot how to dirty flash. i just simply flashed the rom and restarted the phone. it was mandatory to flash custom recovery and gapps after flashing a rom dirtily or normally. but i didn't. After the reboot completed, i remembered that i didn't flashed the twrp and gapps. So, i go back recovery mod, guessed i could flash twrp now. But i didn't see any custom recovery on my phone. But the phone boots, and i can use the phone. Still, i'm on that phone, while i'm typing this comment. i didn't lost my data cause i flashed dirtily. But the problem is, as i didn't flashed gapps or magisk (for root access), now i can't use google apps like, play store, and more. As i don't have root access on my phone so, i can't run flasify, to flash custom recovery. neither i can run other apps that need root. As i didn't flash custom recovery, now i can't flash gapps, magisk and whatever that needs a custom recovery.
I told some rom porter about the matter. They told me to flash stock rom. So, i was trying to flash stock rom. but flashing stock rom requires a fastboot mode. But my fastboot logo doesn't appear and it's blank. I told this to a rom porter. But he said, He doesn't know about that and he can't help.
Just bought a used Pixel 4 to try and flash lineage 17.1 but can't get OEM unlocking to actually work. The enable switch is in the on position and adb recognizes the device but when I try to enter fastboot either by adb reboot bootloader or volume down + power on, the device status comes up in green text "locked." The phone is a G020I and came to me running android 11 with a build number RP1A.20005.004. Is this too new of a phone and wont be able to be flashed? From what I understand, if the bootloader stays locked, I can't even flash a factory image of android 10, correct?
You have to unlock bootloader using fastboot command from pc...

Fastboot commands wont work. adb commands will but as soon as I try adb reboot bootloader to get to the point where I can enter fastboot flashing unlock, I get the result in the pics below.
You need to install Google usb driver to use Fastboot

Ok, in trying to do that, I get the message from windows that their driver is the most up to date and won't let me install from the file I try to choose. See the pics below.
I had the same issue, updating the USB drivers rc13 did the trick.

LInk for that update?

Finally got it. Windows had to recognize it as a generic device in order to force a driver. If it saw it as Pixel 4 it would stop. Now that I have lineage flashed on it, just need to figure out how to get mms to work. Apparently that is a common problem too.
