Why is everything so difficult on this device? - ZTE Axon 7 Questions & Answers

I constantly encounter roadblocks on this phone. Have not had issues with my OP3, Le Max 2, older Note 4 and Nexus 6 . If ZTE is pro this community, why are things not straightforward? On the OP3, simple lock and unlock commands and flash away. Got to do this and do that, 1001 different ideas from people. Right now, my BL is unlocked and I am trying to reinstall TWRP after upgrading to Nougat. This is the message I get when running my adb command to flash recovery:
I have an unlocked BL and recently upgraded to Nougat, but when I try to reinstall TWRP via fastboot flash method, it fails. I have tried two different versions of TWRP 3.0.3-1 & 3.0.4-1. This is the message I get.

It is possible rigth now, for a A2017U full stock in NOUGAT (no unlock, no root) to flash TWRP and jump to LineajeOS 14.1 ?
Thanks

Happened to me. Didn't figure it out on there. You have to re unlock the bootloader to get it to work as it currently shows unlocked but is in fact partially locked. I used the bl unlock kit available and ew unlocked the bootloader then jumped to lineage os. You must get to a point in the zip where it says to fastboot oem unlock and instead type fastboot oem lock. Then start the zip guide from the very beginning again

It's not that difficult, it's just different from hacking a Samsung/HTC device. Just be patient and read. We've all had those same problems and there are workarounds to those problems. But the problem you're running into is you don't have the proper fastboot installed that allows fastboot commands.

[GUIDE] LG G STYLO How to root the T-Mobile 6.0 update

This guide was made before Kingroot was able to root the official update. But thanks to @oskar and @TheDerekHarper on XDA and to @josephwv on Android forums it is now comfirmed that Kingroot will root the official update. But first you must still follow steps #1 through #6 so Kingroot can root your device.
Now before Kingroot was able to root the update I figured out how to root the official update and it is not all to complicated. The following guide will walk you through the root process. But I am not responsible for anything that happens to your devices by using this guide as you are responsible for your device.
What you need:
1. A computer running Linux or Windows with adb and fastboot installed. (I used Ubuntu)
2. If you are using Windows you need all the drivers for your device installed. Linux users will not have to worry about this.
3. A functioning USB cable for your device.
4. Battery charged at least 50% just for safety.
5. The TWRP revovery.img, this is the same TWRP recovery we already have for the LG G Stylo I have just renamed it to recovery.img to make it easier to type the name in while typing fastboot commands.
6. The SuperSU-v2.65-20151226141550.zip by Chainfire. (All credit to Chainfire for this awesome zip.)
How to root your device:
1. I suggest you first go to Settings/General/About Phone/Software info and tap on the "Build number" until it says"You are now a developer". Then back out of until you are in Settings/General and go to "Developer options" and turn "Enable OEM unlock" on. This is to allow TWRP recovery to be able to boot. Also turn on "USB debugging" while you are there.
2. Download the SuperSU-v2.65-20151226141550.zip to your device. You need to move the zip file from your Downloads folder to somewhere on your external SD card as it will not be deleted from there when you use the "fastboot oem unlock" command in step #6.
3. Download the recovery.img to your computer. If you do not have adb and fastboot setup globally for linux or in your path for windows you need to move the recovery.img to the directory your adb and fastboot is in and open a terminal or command line (depending on your OS) in that directory or cd to that directory. If you do have adb and fastboot globally or in your path you can just open a terminal or command line in the directory you have the recovery.img or cd to the directory you have the recovery.img.
4. Once you have the terminal or command line open run the command "adb devices" to make sure your devices is detected by adb. You may get a toast pop up on your device asking if you to "Allow usb debugging". Except this as this is the RSA key you need to allow your computer to communicate with your device via adb. You should see something like "LGH631dffacad9 device" in your terminal or command line. If you see "unauthorized" instead of "device" you have not excepted the RSA key.
5.Now type the following command in your terminal or command line. Type "adb reboot bootloader". This will reboot your device to fastboot mode. Once in fastboot mode use the "fastboot devices" to make sure your device is recognized by fastboot. You should see something like "dffacad9 fastboot". If you are in Linux and get a error message you may have to use "sudo fastboot devices" for fastboot to work. (If you are using Windows and are having trouble with fastboot recognizing your device you need to install the device drivers. If it still does not work install the drivers again with your device connected to your computer in fastboot mode.)
6. To fully unlock your bootloader you have to use the command "fastboot oem unlock". You have to do this or this root method will not work. But be warned that if you do use this command it will factory reset your device. Plus you will get a line of text saying the bootloader is unlocked on the splash screen when you boot your device.
6-1: If you are wanting to use Kingroot to root your device you can reboot your device now. Open the Kingroot app and let it root your device and then use Flashify, Rashr, or a similar app to flash the recovery. Then boot to recovery and flash the SuperSU.zip in recovery and it will remove Kingroot and have SuperSU installed on your device.
7. Now you can do this two ways if you do not want to keep the stock recovery you can use the command "fastboot flash recovery.img" to install the recovery and then use the command "fastboot reboot recovery" to boot to the TWRP recovery. (If this command gives you issue like it seems to be for many then just use the the following method and then use Flashify or Rashr app to install TWRP after you are done rooting.) If you want to keep the stock recovery you can use the command "fastboot boot recovery.img" to boot to the TWRP recovery.
8. Once you are booted to the TWRP recovery you should make a full backup first so you have a backup to restore to in case things go bad. After you make a backup then select install and then find the SuperSU-v2.65-20151226141550.zip and install it. Once it is installed reboot your device to system. If TWRP gives you a warning about the su binaries missing and asks if you want to install thee su binaries before you reboot select no or it will interfere with the rooting process of the SuperSU.zip. When your device reboots it will boot to the LG splash screen and then reboot again. But then it will boot to the OS but it will take a minute. Make sure you let your device reboot all the way to the lockscreen or home screen depending on if you have a lockscreen enabled or not. You should be fully rooted after this, enjoy.
Resserved in case needed later.
Thank you.

Someone mentioned using the Kingroot app and I gotta admit, I was skepticle at first but after testing. I can confirm it works.
Just go go KingRoot.net, download their apk, install and run the root program. Igll work out of the box after, sadly I couldn't get the above method to work either with super su.

do the fastboot boot recovery.img so it boots up twrp then flash the supersu zip then boot your phone you should be rooted then flash twrp using flashify
I was getting the same error, ( in step 7 don't flash the recovery )
just use "fastboot boot recovery.img" and it will boot to TWRP without installing it
you can then install SU, ( note ) when you exit or re boot from TWRP it will say SU in not installed do you want to install it, I did the first time and it seemed to hose up, so I did everything over and the second time selected no to re install.
once booted I used flashify to install the TWRP img, and I am able to boot to recovery using Quickboot apk
on a side note I have SU installed, I can use root explorer and other apps that ask for SU access, but Titanium backup
doesn't seem to uninstall apps anymore, they seem to re install after a reboot
Hope this helps yall's

I gotta be honest... I'm pretty skeptical to try it. I've read of everyone having either a softbrick boot loop or the root just not staying after reboot. Yours worked for H631 T-mobile 6.0 and stayed? If you confirm T-mobile variant and 6.0 I'll try it. There's a lot of headache with this method for me (not saying it doesn't work). I bricked my phone trying to get the binary files for SU by trying to reroot. But unbricked it with LG Flash Tools and a stock kdz. So I don't want to brick it again twenty minutes later lol

Made a tutorial on how to get the marshmallow update (i.e. rom i've used.)
And then afterwards i downloaded Minimal ADB & Fastboot, OEM Unlocked the device (for safety) and downloaded the Kingroot Apk.
Installed it, and just allowed the program to root. It was pretty simple, haven't had any issues (i've even disabled OEM Unlock from the phone & USB Debugging.)
Hell, even adoptable storage is enabled for my phone too (but that's another tutorial from somewhere else.)
I do plan to make a root video, just so someone could see it and grab their opinion.
To be clear: I'm using a metroPCS LG Stylo. Also, only time the phone had issues was when i factory reset it to get rid of root. (didn't work)
so i had to follow the steps from the above tutorial to reflash the stock rom.

well this did it, the root actually worked.
I got a permanent root from the procedure listed on page one of this thread. The only thing I did differently was, when booted into TWRP and you try to re boot the system you will get the question if you want TWRP to install root. If you do allow TWRP to install root, you wont get root. At this point select the option to just reboot the phone. The LG Logo will appear twice before it fully boots. When the device is fully up, you will have root.

My apologies as I made a typo in the guide. The correct command is "fastboot flash recovery recovery.img" to flash the recovery. I will fix this along with another rework about putting the SusperSU.zip only on your SD card.

I do not know if you can use it or not as I do not have that device. But you can try it bit if your device does not boot to fastboot mode when you issue the adb reboot bootloader command then your device's bootloader is not unlockable and this root method will not work for you. But from the posts in this thread point out that Kingroot now works on the 6.0 update so you can also try Kingroot to see if it willroot your device.

Is there anyway to do this without wiping your data from 'fastboot oem unlock'? My bootloader keeps saying locked in fastboot mode even though I checked Enable OEM Unlock in settings. It won't let me boot the recovery.img because it's locked.

Hmmm looks like maybe fully unlocking the bootloader enables all fastboot commands. You can try downloading and installing Kingroot and root with it as the posts here comfirm it will root the update now. Or just u lock the bootloaderb but your device will be reset if you do.

What if we just enable oem unlock in both the system and the bootloader then use adb to push the recovery, superuser, and busybox to the system. King Root caused too many system instabilities, it had injected itself as a system app and after unrooting and uninstalling after a reboot I was left with a soft brick due to a secure boot error 1003. A stock 5.1.1 kdz and the lg flash tool was able to bring my Stylo back to life.
It could all be done by running a simple batch file bundled with everything we need for our device. Linux would probably be the better option but it could work the same in windows.

Screwed up phone while rolling back Android 7 - help?

So for some background, I was on EMUI 4.1 and successfully flashed to EMUI 5.
Then, I wanted to rollback so I flashed recovery again and stock firmware. I tried flashing with fastboot and didn't work. I tried using Huawei recovery 3-button method, no luck either.

When I was booting into Revolution recovery, I could not mount SD card and some other partitions so maybe that has something to do with the 3-button method problem... Furthermore, I don't know how to check which version exactly my phone is, all I know is that it was VNS-L31.
Now I'm stuck with a phone that is constantly rebooting so how do I proceed?
First of all...
Please tell me you have a backup of your Nougat ROM. If yes, restore it.
I have failed to go back to MM several times like you before.
It really is a question of using the right files.
First, flash the OEMInfo that is provided here in the forums.
Second, flash the right firmware. This one is tricky. For me, ONLY VNS-L31 Version C150 worked. No other.
Flashing with fastboot always never works. It always gives an error on system. So you need to find a firmware that works with 3-button method.
Your task now is the get back to working Nougat, since you did something wrong.
Unlock BL, flash Nougat recovery with fastboot.
Then,
easiest is like I said restoring a backup.
If you don't have one, try flashing the Revolution ROM by BadWolf.

Have just solved the problem with the steps from here.
From my understanding, it seems that I lost almost everything, device info, OEM info, recovery... So no technique was working.
The solution in brief was:
1. Go into bootloader to flash recovery (I used Revolution Recovery)
2. In recovery, flash OEM info.
3. Then used the 3-button method to install stock version for the appropriate model (which I could see from OEM info).
4. Unlocked bootloader, triggering a factory reset. (I was stuck in infinite boot before this point.)
As you say Schlengge, it is a matter of using the right files! Thanks. Problem solved.

TWRP on Nougat

I saw where someone said you could flash B20 bootloader and flash TWRP on Nougat, is this true? Is anyone working on a guide for Nougat TWRP and root. On another note I thought that I read that ZTE would be bringing Wifi calling for Nougat with carries such as T-Mobile? I was unable.to find it under options and assume that it is not possible, anyone have any idea about this.
Thanks

I got TWRP 3.0.4 installed (as well as 3.0.3-1)... It installed sucessfully via Fastboot for me, I even flashed SU, but I couldn't get my phone to boot into the OS (tried with and without SU).......It just hung at the boot pre-boot screen (where it warns you the bootloader is unlocked). I'd restart it, and it always hangs at that screen..... Only way to fix it was to boot back into TWRP, revert back to B29 (using DrakenFX guide) and then update to Nougat again. I spent about 16 hours straight working on this on Tuesday, before I gave up and decided to keep it stock until a custom ROM comes out, soon (Z.A.D. v.4), hopefully?
I have an issue where I installed B15 but whenever I boot my phone, it hangs on the Linux Tux logo. Any fix?

You probably pushed the power button to "Start"? Try letting it sit there about 10-15 seconds, if it won't boot...This is the exact same problem I had. I had to go back to B29, then do the update again. There is now a B15 "return to stock" walk-through, that may be the quicker route.....But I know returning to B29, turning on OEM Unlock in Dev options and then taking the update via your SD card was what I did (3 times in one day).

Those 2 XDA links don't work, take me to a generic XDA 404 error page (on both)...the WeShare page worked.

If my bootloader is already unlocked, can I skip that part (the 2nd link)?? Or is it necessary?

Those steps are meant to unlock the bootloader.
You don't need any of it. You already have TWRP (skip step 1) and bootloader unlocked (skip step 2) so yeah...
What do you want exactly?

My bootloader is unlocked (back when ZTE actually provided the unlocking)....adb fastboot works on my phone as well and I've flashed TWRP (3.0.4 and 3.0.3-1) and it's booted into TWRP, but I cannot boot into the actual OS...My phone goes all black and just hangs there, I think this may be booting directly into EDL mode and not the OS? I can plug my phone into the computer and my computer makes noises as if a USB device has been attached, but my screen is completely black. If I push the start button while the phone is booting (to bypass the bootloader is unlocked warning screen), I boot to a small penguin screen.
The only thing I can do from there is revert back to stock B29, then update back to stock B15.
I want to be able to install TWRP, root my phone, on Nougat, and be able to use my phone too?

Then follow this:
https://forum.xda-developers.com/axon-7/development/edl-emergency-dl-mode-twrp-unlock-t3553514
and flash this:
https://forum.xda-developers.com/showpost.php?p=68873482&postcount=2
I think I know what happened to you... did you by any chance allow system modifications in TWRP? That makes the OS bootloop if you have Nougat.

The MiFlash program found my phone, but failed every time I ran it.. So, I just bit the bullet and downloaded the latest TWRP 3.0.4-1 and flashed that.....And it worked! I then flashed SU, my fonts and changed my Emoji's....I'm about there with customization, and it's all booting up just fine!
But, yes the first few times I did allow system modifications......But I also did this last time too and it's working fine?

messed up unlock.

Followed a tutorial on how to install lineage-14.1-20180817-UNOFFICIAL-cedric, but somehow missed a step or messed up.
I unlocked the bootloader, not exactly but in general: flashed the boot.img and rebooted, phone started and was able to use android.
But some strange problems occurred, like somehow my PIN was not recognized and device failed to factory reset.
Locked the bootloader again because of the warning (here's my mistake I guess) and now am unable to flash or revert to stock.
I am able to boot into android, did enable USB debug and bootloader unlock.
But everytime I boot I get the warning a different kernel has been installed (instead of wrong key before) and permission is always denied remotely.
C:\ad>fastboot flash logo logo.bin
Sending 'logo' (2186 KB) OKAY [ 0.068s]
Writing 'logo' (bootloader) flash permission denied
FAILED (remote: '')
Finished. Total time: 0.077s
This happens with everything, permission denied.
If I try to unlock it again via fastboot commandline (Windows) I get:
"(bootloader) invalid boot state"
Starting the phone in fastboot, the status is "flashing_locked".
What can I do now?
I am a noob, therefor the tutorial...
Thanks

First, this thread is for g5 plus not for g5, so post in that thread.
Solution:- which firmware you are trying is it for g5 or g5+, if you flash wrong firmware then this happen, try downloading your firmware and then flash it.now you are on stock. If you don't know how to Flash, you can prefer XDA threads or use Lenovo Moto smart assistant app (pc) that will flash the firmware for you.
If you want to go on custom ROM then, first go to stock rom as it will restore your boot.img and custom ROM can work. If you directly want to go to custom rom (skiping above procedure) then flash boot.img from ADB or twrp and install custom ROM.
Here is the thread to Flash stock ROM:-
https://forum.xda-developers.com/g5...-flash-stock-romfactory-t3691396/post74221633
Link for Lenovo Moto smart assistant app:-
https://support.lenovo.com/in/en/downloads/ds101291
And if you are using XDA threads it has old firmware which can brick you Device you can get your firmware from here and chose which firmware channel you belong:-
https://mirrors.lolinet.com/firmware/moto/potter/official/
At last to not take risk remove bootloader and gpt commands from ADB.
It is a G5 Plus and I get permission denied with adb or fastboot.
In android I van go go developers option and OEM unlock is ON, if I go fastboot, flashing is locked.

Well LOS14....-cedric is the G5 variant. You didn't flash the wrong firmware did you?
Apperently I did...
Is there a way to fix it?
the Lenovo recovery tool mentioned above doesn't do anything with the "flash" option.
Put the phone in fastboot mode and it is not recognized by the Lenovo application.
Can still manual send fastboot and adb via the Windows command line but still "locked" and "pemrission denied".
the command fastboot flashing unlock did the trick for now.
But, I want to revert to stock, what is the correct way?
Can someone point me to a good how to or tutorial with recent files?
EDIT: I see LineageOS officially is not supporting the G5 plus, but there is a unofficial version in the G5 plus forums.
I'm still thinking of customizing because of all the bloatware and sluggish performance.
reïnstalled TWRP, put Pixel Experience on an SD card, booted TWRP recovery, did several attempts to clean all data / cache etc. but got several errors, retried, rebooted, chose all options and installed Pixel.
First try phone did not boot, froze on Pixel boot, again wiped everything, again installed Pixel and now it boots.
good lesson.
Phone is not entirely recognized the correct way, google security speaks of a Moto X (4) and the phone itself mentions the exact model number instead of Moto G5 Plus.

Yeah security does show as Moto X4. That's normal.
One final question: On reboot I always end up in the fastboot menu without holding power and volume down, I also always get the unlock warning.
Is this a sign the bootloader is still not okay?
And is there an easy way to fix it?

+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
View attachment 4783849
Here is the twrp which I'm trying to flash

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.
