So after all i can confirm the method is working for A2017G with B08, but i had to modify some steps:

Prior to Bootloader unlock only tenfar's recovery was working for me. (This)

Dont use it for any other purpose than BL unlock though, as it is buggy, especially DO NOT BACKUP OR RESTORE EFS with this.

After i unlocked the BL (procedure as in OP), i was able to fastboot flash the normal official recovery and it works.

So atm i only rooted stock by flashing supersu in TWRP but I'll probably soon will change to cm.

I changed to this "official" recovery and get a black screen whilest booting into recovery, restored previous TWRP for now
[ZTE Axon 7 Guides, News, & Discussion] Controllerboy:
:s I had changed the TWRP version to the official one since the unofficial version creates dangerous EFS backups. Okay, I might change it back again but BEWARE not to backup and restore EFS with that recovery version, it killed my cellular data :(
[ZTE Axon 7 Guides, News, & Discussion] Dust2Dust:
Have no plan to do so ;)

Will the rest of your tut work flawless from here??

I mean unlocking bootloader in order to root the Axon ?? I have no need for CM.
[ZTE Axon 7 Guides, News, & Discussion] keessonnema:
It's possible to unlock BL and root, but you have to be aware that you can't backup with twrp. Because the official one doesn't work and the tenfar ****s up efs backup.

I've asked a dev to help me with the A2017U TWRP to make it compatible with EU model. I'll keep you guys updated :)

Nice work with this thread: thanks a lot for collecting all informations.

1. The link to the twrp did not work any more.

2. I got stuck on step 16: the backup of the device. The command "axon7tool -r gpt boot recovery" always displays (Win10 x64):

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

I also tried installing other drivers (additionally with disable the automatic installation of them) and/or replace them with Zadig, but I have not found a solution. The hardware manager displays the device as "QUSB__BULK" without a warning.

in the pinned [Download Center] Thread i read that using the linked TWRP can cause issues. Does this guide also work with a newer version of TWRP?

Backing up with the linked TWRP can cause issues. He doesn't tell you to backup anywhere. Just do what he says, and when you finish doing everything you can update it by installing the 3.2.1-0 img via twrp

So I followed the guide carefully.

*edit

just forced the device to reboot. is this normal? what can i do to avoid it?

Im on a win10 x64. did run the console with root permissions (was that an issue?)
[ZTE Axon 7 Guides, News, & Discussion] Choose an username...:
I'm guessing you didn't reboot EDL after installing the zadig drivers? Do this:

-Get into EDL

-Attempt to flash with axon7tool

If it doesn't work, a)check that you have file extensions enabled (if you don't, you'll rename the twrp.img to recovery.bin.img and it won't work), b) restart edl mode (hold all 3 keys until the LED flashes, and the device manager refreshes itself), then try again. If axon7tool fails just restart edl again until it flashes

Hi guys, I have the g version and I'm sick of the mifavour on nougat.

I came here to find some guides to unlock the phone and flash some rom.

My question is, since i'm on nougat, how can I change rom?

I have to unlock the bootloader first and then flash the twrp or viceversa?

It's mandatory to start from android 6? if yes how can I downgrade?

Thank you in advance :)

p.s. which rom is the best in terms of bugs(none at all), camera and battery life.
[ZTE Axon 7 Guides, News, & Discussion] Choose an username...:
Just use EDL Tool by djkuz, it should unlock and install twrp. Then use twrp to install ROMs. But remember ALWAYS TO FLASH MAGISK OR SUPERSU BEFORE BOOTING FOR THE FIRST TIME (after you change ROMs or format data) because your internal storage will get encrypted, and you'll have to format it the next time you change the ROM (you won't notice until you change the rom).

Everyone asks about ROMs, I'd tell you to look around. For less bugs you have Nougat, and AEX Oreo is pretty okay (encrpytion and dual sim calls are bugged, maybe something else)

[ZTE Axon 7 Guides, News, & Discussion] Oki:
Some people forget to do the second unlock step from within TWRP by doing a "reboot disemmwp" command from within TWRP or even from your computer using the adb interface while unlocking it, just tipe in your computer "adb shell reboot disemmcwp".
[ZTE Axon 7 Guides, News, & Discussion] Choose an username...:
i'm pretty sure it only works through adb though
[ZTE Axon 7 Guides, News, & Discussion] Oki:
Not really. You can open a terminal in TWRP and type reboot disemmcwp. Also the TWRP 3.2.1-7 has a button in the reboot menu only for that step.
[ZTE Axon 7 Guides, News, & Discussion] Choose an username...:
I haven't tried that button (seen it, but i have emmcwp already disabled) but I am sure that simply issuing reboot disemmcwp from the twrp terminal or from the system does nothing. 2 or 3 people from here (and me) wanted to remove that and the only way possible was via adb. That was about a year ago though.

For a company that has the crappiest software on the planet, they have to make it the most tedious process ever just to unlock the bootloader. I love how it's an option in the dev menu even though you need to jump through countless other hoops, download and install lots of shady apps and drivers, and then jump through even more hoops just to get TWRP running.

Never will I buy another ZTE phone. They pretty much nail the stereotype of "crap Chinese" software/ hardware. I am very happy to see that their duo screen phone failed miserably. LOL. Morons.
[ZTE Axon 7 Guides, News, & Discussion] Choose an username...:
Lol. You'll be missed.

The option in the dev menu is AOSP, nothing else. And do the major phone OEMs let you unlock the bootloader easily? Samsung as the prime example? (Let's not even talk about Apple, but I guess you know you're buying closed-garden stuff with them)

The hardware on this phone is 10/10, tell me what is wrong with it. The only thing you could possibly say anything bad about is the back camera, which is no "crap Chinese" camera, since it's even made by samsung. Hell, the phone even has a vapor chamber on the CPU

The software is obviously sort of bad, but you probably paid $250 for this (or less), so i don't know what you expected. An OP3/T would cost you at least $100 more.

Try the leaked betas before saying anything else, though. They are much better than stock M/N

For the screen thing, maybe you could try KCAL? The saturation setting won't make the colors pop too much, but it's better. I don't see it as less colorful than an IPS panel but that's your opinion i guess.
[ZTE Axon 7 Guides, News, & Discussion] Stoofvlees:
Getting there...

OK So fist thanks for great guide so far... and I read through nearly all previous posts so I think I'm at the end of what I can achieve..

A2017G on B11

MM

here, official downgrade from N (from ztedevices) just to be able to do this guide. Win10 64bit.

Followed step-by-step from OP works up to and including point 22 but stuck on point 23 (I have the 3 backup files).

PS - Zadig WinUSB trick was indeed necessary to finally get QUSB_BULK, but it worked.

(For any1 else stuk in earlier steps: make sure you're using administrator privledges for everything (cmd, zadig, ... everything) and just keep trying, QUSB-thing is really important - )

SO now stuk on point 23: black/blank screen after volume+ & pwr, with red led flashing. No way to "boot into TWRP" (point 23). Nothing to see. No old recovery mode with the small font. Ev. gone, blackness!

Holding down volume+ & pwr continued simply ZTE logo keeps appearing.

Normal start by pressing pwr alone works, then system just starts normally and gets into MM.

I used this "latest" TWRP from {outside link suppressed} "twrp-3.2.3.0-axon-7.img" because it was the link from LineageOS install guide and TWRP link from OP is broken 404 error (sorry, impatient...)

I think some signature recognition TWRP issue probably based on previous posts...

What should I do now, I want Lineage 15.1 on the device eventually... total n00b so talk to me like I'm a baby! No important data on phone, so wiping is fine.

I think TWRP version is the issue but how to proceed? Some people have said "flash TWRP again" but do I need to revert to the backups first? #confused.

Just to clarify:

On my A2017G with B08 tenfars recovery was the only one working prior to unlocking the BL. After it was unlocked, the official one also worked.

I think you can however also backup and restore stuff with tenfars TWRP, as long as it is only /system /data or maybe /cache. To that matter one usually would not need to backup anything else.

I myself restored /system once from a backup i made with tenfars and all is fine.

1. unlocking bootloader witn tenfars recovery.

For everyone that's stuck in edl mode because of axon7tool saying "Failed to connect" do the following:

4. when in edl mode open zadig 2.2 again and install driver
