[GUIDE][A2017G] Reinstall TWRP and Root after update to Nougat - ZTE Axon 7 Guides, News, & Discussion

Get TWRP and root after updating to Nougat​
This method worked for me, but be aware, it might not work for your specific device. in a worst-case scenario, you'll brick your device - proceed at your own risk!
For devices with UNLOCKED BOOTLOADER! This guide does not show you how to unlock the bootloader
BIG thanks to @tamahouse02, @bkores, @S0wL and @tron1 for the help they gave me when trying to do this on my own device. This post is just a compilation of everything we tested over the old questions/answers post.​
How To:
Set up axon7tool and download TWRP
Download axon7tool from here. Thanks tennear for the awesome tool
Download TWRP for ailsa_ii, newest one available. I used 3.1.0.0
Download Zadig and throw the exe somewhere
I asume that you already have adb installed, if not install it with 15 seconds installer
Put axon7tool on your adb folder, rename it to axon7tool.exe
Put TWRP image on the same folder, rename it to recovery.img (you NEED TO BE ABLE TO SEE THE FILE EXTENSION! Google how to enable that)
Duplicate the recovery.img, rename it recovery.bin, keep it in the same place
Connect your phone, enable USB debugging, open CMD and run adb reboot edl
Open Device Manager once your phone looks like it's off. You should see a Qualcomm HS-USB QDLoader 9008 under Ports - COM & LPT, uninstall it AND TICK DELETE DRIVER SOFTWARE TOO and hold the three buttons of your phone (vol buttons and power) for quite a lot of time, until you see that the device manager list refreshes. If Windows attempts to install the driver cancel it at once, repeat the process if it did install it (it appears as a Qualcomm thing again). After holding the 3 buttons you should see an unidentified device named QUSB_BULK
After you have the QUSB_BULK device fire up Zadig and Install the driver.
Flash TWRP using axon7tool
Hold the 3 buttons of your phone again until device manager refreshes
Open CMD on your adb folder (go to the folder, SHIFT+right click anywhere, open command window here)
run axon7tool -r recovery gpt boot
Leave CMD open. Go to the folder where the tool is and make a folder named backups or whatever, put all the backups there (recovery_backup.bin for example)
You should have made a recovery.img and recovery.bin there before. Check that you left them there, just to be sure
Finally, on the CMD window, run axon7tool -w recovery. If it fails try holding the three buttons, opening cmd again and trying this step again. otherwise post your error here
If it succeeds disconnect your usb cable from the phone BEFORE THE COUNTDOWN ENDS, then hold the power button for like an eternity until the phone reboots. If you don't do this your TWRP will be replaced by the stock recovery. you only have to do the previous step again in that case, don't worry.
Either while the phone is booting or with adb after it gets to system, get to the recovery and test if it boots. Congrats if it does!
Install SuperSU
You probably know how to do this if you came this far. If you don't:
Download SuperSU 2.79 from somewhere on the internet
Get to TWRP
Flash SuperSU
Avoid the inherent nervous breakdown that the initial bootloop causes (in layman's terms, don't freak out, let it do its thing)
Done
Get Fastboot
Download this ZIP (thanks @sToRm1nG) and put it in the root of your phone's storage
Go to TWRP and flash the ZIP
Boot system and adb reboot edl
Now we need to replace the Zadig driver, sorry you'll find QUSB_BULK under USB devices (bottom of the list in English), uninstall and check Delete driver software too
Hold the 3 keys
Windows might attempt to install the driver. Leave it, hopefully it will. You need to get Qualcomm HS-USB QDLoader 9008. If it appears as an unknown device google for the driver (just google Qualcomm HS-USB QDLoader 9008 driver and you'll get it) and install it, then hold the 3 buttons and check if the QDLoader 9008 appears under Ports COM&LPT
Download MiFlash from here, and the fastboot package from here
Unpack the fastboot package somewhere, be careful not to unpack it like a folder with another one inside, but rather one folder directly with all the stuff inside
Open MiFlash and select the folder that you unpacked
Select Refresh, then your device should appear. if it doesn't then you didn't reload EDL or you didn't install the Qualcomm drivers, simply do that again. If it appears go ahead and choose Flash
Reboot and try if it worked, by selecting Fastboot from the 5 sec menu or using adb once you're booted
All done. I'm not a developer of any kind, so I'm afraid i won't be able to help with specific errors. But most simple errors you could have are described here, so you should have little trouble doing the procedure.
Hope the best of luck to y'all while doing this

I just tested unfortunately with the much less easy to read original problem thread that described process works fine! Thanks!

---

Thanks for the Guide!
My Axon 7 (G-Modell - Nougat 7.1.1) is located in the EDL and is under Device Manager as
"Qualcomm HS-USB QDLoader 9008" detected, but MiFlash does not recognize it. The latest drivers from Qualcomm are installed and I use the original cable from ZTE, but it does not want to be recognized ;-(

Thank you man!I'm already Rooted in Nougat 7.0 in my A2017G..... But AdAway can't write the host file, do you have the same issue?

---

No idea, I never use AdAway. BTW can you cut down the quote a little bit? A lot of people complain about the huge quotes

Did you try to get to TWRP? Does it show the BL unlocked screen, or just the boot logo?

---

Otherwise try to get to fastboot however you can, then flash TWRP again, or you can try getting to EDL and restoring the backups that you hopefully made. I have no idea how the DFU mode thing is, but I would do some research on that. I'm no dev

Thanks for this guide saved my day.

do i need an unlocked bootloader for this to work?

I assume you do. Try the method in here. I have no idea if that will work for Android 7.1.1 though, so I hope you still have android 6

Please help, I have the same problem as logimowl:

"Qualcomm HS-USB QDLoader 9008" detected, but MiFlash does not recognize it. The latest drivers from Qualcomm are installed and I use the original cable from ZTE, but it does not want to be recognized

@icaros1530 Huh I've just installed 7.1.1 official today, so I have to do the process again. I've just opened MiFlash and it detects stuff nicely. The device appears as COM5 on MiFlash and the driver is under Ports (COM & LPT) with the name Qualcomm HS-USB QDLoader 9008 (COM5)

Thanks for checking and posting the screenie. I've been on the issue since yesterday now and found a suggestion to try on a different computer, so I tried again and it worked on my win10 notebook. So issue is insofar solved as my smartphone is now running 7.1.1 and rooted and all. Why miflash just can't connect on my win10 pc.. I have no clue. I've rebooted device and pc tons of time with different drivers, even trying the old root methods, used zadig whatever. Everything looks the way it should - but some minor thing hiding somewhere just won't let it work.
td;dr: if miflash can't connect try different computer..

That doesn't work for me. The command reboots the device, but Adaway keeps saying host files couldn't be copied.
SOLVED: for 7.1.1. we seem to need the systemless version of adaway. I picked up version 3.2 from here and it works perfectly: https://forum.xda-developers.com/showthread.php?t=2190753

@icaros1530 lol I'm gonna add that to the OP (try different computers if it doesn't work)
All these programs are extremely nitpicky it seems!
And I uploaded 2 pictures, but only one showed up, so I just deleted them and added some text. That's why i edited, i just wanted to make that clear

---

Thanks dude! Clear and simple instructions, got TWRP and root running on my A2017G 7.1.1

Yes using Miflash
A few reboots of phone and laptop and it flashed.
