I downgraded from custom Nougat to stock Marshmallow as I discovered that the incall sound (hearing the caller from the ear speaker) is louder and clearer, so of course I lost TWRP recovery and root in the process which is normal. However, I now can't re-install TWRP as a .img file since although I can boot into Android Recovery I can't go into Fastboot mode (phone just re-starts every time) so of course it's no go whether I try Axon Toolkit or ADB via computer. I also tried the EDL route but same thing.
I have all the required ZTE and Qualcom drivers installed. My phone's model is the 2017G and the bootloader is still unlocked.
Only thing I can try is installing TWRP as a zip file through Android Recovery or directly from 'system update' via the phone's menu. Problem is I can't find a zip version of TWRP for the Axon 7
Any help/suggestions most grateful.

If you can use miflash there is a thread somewhere that has stock everything with twrp included. I'm on my phone so I can't find it right now. But if you can't find it by the time I get to my computer I'll look through my history to try and find it.

So the thread I found was actually not for the g model sadly. But, have you seen this thread?
https://forum.xda-developers.com/axon-7/how-to/download-center-factory-images-ota-t3606547/page10
Down a ways there is a "TWRP flashable bootstack/stock system images" section. I think if you can flash those (maybe with miflash?) You should then have fastboot available to flash twrp again.
When you unlocked surely you learned how to use the tools to flash twrp without fastboot.
You can use miflash, the toolkit, tenfar's tool or tenear's tool.
There's a million and one guides on how to to this plus the actual tool threads.
Even the twrp thread has a guide.

I took a look. Not sure which version I should download. Am on B10 and that section only has bootstack versions up to B9. Does it matter which one I choose or should I get the closest which is B9. Also, should I install the stock system that goes with the bootstack version or just the bootstack.
Thanks for the link.

Okay so since I was not paying that much attention (sorry) I just realized that those are bootstacks and stock systems that you can flash in TWRP. My bad. But I have been looking around and on that thread I just had you go to he mentions another thread with step by steps that may help you! Here it is. Good luck!

Ignore the fastboot part. Just reinstall twrp with axon7tool, then install raystef66's TWRP flashable B09 bootstack and stocksystem zips (plus magisk if you won't relock), then follow his guide on how to get rid of the 5 seconds screen to get fastboot and, well, get rid of the 5 seconds screen
p.s. I basically just found out that I said the exact same thing on that crappy Q&A thread...

The link you provided is titled 'Get TWRP and root after updating to Nougat'. As am on Marshmallow I'll have to first update to Nougat? . So do I go ahead and flash stock Nougat from ZTE's page before following the instructions on that page? Sorry for my confusion.
**Update** I followed instructions of link you provided to install TWRP but I came to a brick wall every time. Short story is no matter what I tried I cannot install anything with either ADB, Miflash or Axon Toolkit. The big problem here is the Fastboot issue which otherwise would make things so much easier. Only thing left for me to do is just to upgrade stock firmwares via the phone's update option and remain bootloader unlocked. The Axon 7 is still a great phone, it's just too much hustle getting things done so I'll just have to sell it. Samsung and HTC phones are much easier to work with when it comes to rooting/installing custom ROMs.
***Update 2*** Success!! I managed to install fastboot/bootloader mode by following the section 'Get Fastboot' from that same link you provided so now I have latest TWRP installed and the 5 second notice has also disappeared. Am back in the running now. Many thanks for your help

You could have bricked your device. I specifically told you not to follow that part. Also what has adb, axon7toolkit and miflash got to do with that guide? You have to use axon7tool just like a) it says there and b) i told you on the q&a thread

Yes you did warn me about the fastboot part but I was stuck as nothing else worked. By using the Fastboot instructions I managed to install TWRP and root the phone. I used Miflash to install the fastboot package which was successful. Now I can boot to Fastboot and bootloader via TWRP. Remember am on Marshmallow so I guess that helped not to brick the phone? I don't know but it worked.

Well again, if you want to be on Nougat, download raystef66's flashable B09 bootstack and stocksystem, flash them on TWRP with Magisk 15.2, and follow his guide on how to get rid of the 5 seconds screen (all in twrp, don't get out of it).
Just do all of that or you'll lose fastboot. Also that zip that you got from that ancient guide doesn't work on anything else than Marshmallow

Thanks for the advice. If I keep the phone I'll wait for a stable Oreo update. Nougat didn't impress me much.

Can someone walk me through how to Unlock the bootloader, root, and install TWRP? I'm so confused. I tried to do the newbie way, even though I'm not a newbie, and I lost my B29 Stock Recovery and can't find the download for it.
Sent from my ZTE A2017U using Tapatalk
I haven't done it yet but I've done a lot of reading and this seems to me the best guide.
Head over to this link which is the TWRP thread. https://forum.xda-developers.com/axon-7/development/recovery-official-twrp-zte-axon-7-t3515715
Once you're in there go to bootloader unlock section. Download all the necessary files and on the bottom of the guide there will be instructions link which will take you here https://build.nethunter.com/misc/axon7/INSTRUCTIONS.txt
Follow that and that should do it.
When i get a weekend off ill be using this method to get the Lineage OS 14.1 on my device.
Search, Read & Follow --CAREFULLY--.
It's been a while, but this worked great for me, starting from B29.
Goodluck
Let me tell you, this is the guide that should be pinned. It gives very easy/clear instructions on what you need to do to root/flash recovery and even going back to stock. Very well written and I wish I had seen it sooner. I was going to write a clear guide on this subject only to find.. it already existed.. --nolimit78
@amphi66 I am on 2017U B29 and want to unlock bootloader, install TWRP and root. I also read newbies thread. I am confused about one thing. which TWRP recovery image should I use? a2017u B27 http://d-h.st/kRgq or TWRP recovery 3.0.2-2 : http://d-h.st/dgWW ? There is no file for B29 on newbie's thread and in FAQ, the OP said B27 should work for B29. Which one did you use?
After reading, I also see some people said tenfar's tool is too dangerous and it may brick your phone. Some people also claimed the back up of TWRP recovery 3.0.2 provided on that thread has some bugs may cause you to loose your IMEI number when you do recovering. Do you have any issues? Thanks!

This was back last Nov, but I followed the guide, using the recommended files (was on B29, but used the B27 OK, then reflashed B29 at the end).
The warning involved backing up and then restoring the EFS partiton with tenfar's tool. DON'T! If you stick with system, data, and boot partitions you should be fine.
Good luck. You may want to check with @nolimit78. He has done this much more recently.
Yes, I agree with you @amphi66 that there is a lot of different places to get information about how to root/flash recovery for A2017U B29. Here's what I've done with two different A7's and both have worked each time.
1. Boot the phone to EDL Mode (Both Vol+Power on boot it'll quick flash the red notification light and then act like it's off.. it's not)
2. Use tenfar's tool to flash the recovery. (I renamed the updated TWRP img and named it "recovery". This used tenfar's tool to flash the updated TWRP on your device.
3. Once in TWRP, run the command (reboot disemmcwp and relaunch TWRP) and flash the package to use modifiable bootloader from B20.
4. Once that flashes now you can send the command in Fastboot "fastboot oem unlock" which will unlock the bootloader that doesn't trip anything notifying ZTE
5. At this point you can flash a B29 rom and have a grand ol' time. However, I would recommend using the LineageOS Rom that's available. Trumps everything else out there IMHO.
6. To do that You'll need to flash the Nougat Bootstacks for that rom to boot prior to flashing the Rom itself. I would recommend flashing the nougat bootstacks, reboot to TWRP, flash LineageOS, reboot.
Like I said, I've done with this with two different devices (Thanks ZTE) and both worked out just fine. I did this method with a device with b27 and b29, both ended up updated and flashed with CM/LineageOS with ZERO issues. This post here should also be pinned as the one true guide (THE KING OF THE NORTH) for unlocking/rooting a stock Axon 7. I spent probably about 4-5 hours working, trying to figure out how to get my device unlocked/rooted. However.. at the very end I wrote out instructions trying to help those who would come after me.. I searched the threads to make sure there wasn't already a thread out there.. and then.. it turns out there was.
Someone have the 5 files to unlock the bootloader 2017u on drive
Hey guys, first of all sorry about my english, im french.
So my problem is: I tried rooting my Axon 7 A2017U many times, with different guides. I always end up with a softbricked phone, having to restore to stock using MiFlash.
My bootloader is unlocked, i have stock recovery and stock rom for now.
Whenever i flash TWRP, either the signed one (from @tenfar) or unsigned (and up to date) ones, i can't go past the menu saying something like "your phone cant be checked for corruption, please lock your phone [...]" it just freeze. i did read somewhere that i should flash chainfire's root or a special .zip that, i guess, disabled some check that could prevent booting a phone with unsigned stuff/edited system (after flashing TWRP, so it could boot) that didn't work out. i think i found that information in some LineageOS thread here on XDA.
My ultimate goal would be to get a rooted stock nougat 7.1.1, up to date TWRP recovery and to be able to switch to LineageOS to try it out soon.
For what it is worth, i rooted many phones over the years, so while i'm no expert, i should be able to follow most of the steps you give me.
Thanks alot!

Okay. Download and flash this one alone via fastboot and see what happens. This is one the I personally use. It is required for any of the newer versions to work properly.
twrp-3.0.2-2-a2017u.img
You can choose to rename it to just recovery.img, then:
1. fastboot flash recovery recovery.img
or
2.
if you choose to work with the same filename:
fastboot flash recovery twrp-3.0.2-2-a2017u.img
Select reboot to recovery from the bootloader menu now and try again.
Either way, should work fine. I know you mentioned you knew the basics, but just want to be sure.
Also forgot to mention. If TWRP works but you still can't get your phone to boot, you need to follow this guide here
You can start from the part that says:
-----------------------------------------------------
UPDATING FROM B20_Boot / B20 / B27 / B29 / B15(N)
-----------------------------------------------------
Again, that's the ROM I personally use if I want to go back to stock, not the one from the ZTE site.
Gonna try it and give feedback. thanks for taking time to help!
edit: im downloading the rom from the link you shared.
like you said, i can get TWRP to boot but not the phone.
So if i use full stock from ZTE, it can't boot with modified recovery?
edit 2: i don't know what worked, i think it might be the bootstack. or the rom by DrakenFX. now i can boot to the rom with a TWRP recovery installed. It worked, but i soft bricked again trying to flash SuperSU. So now i'm retrying with an updated TWRP.
I haven't tried that yet, but I really suspect that's the reason you're having problems. I rarely use pure stock ROMs. Like you, I'm not an expert in Android Development so I can't tell you why. Just been a flashaholic for years so made a few observations.
Which supersu are you installing? If you're swiping to the right in twrp, you need to install the dm-verity zip or supersu 2.79. There's some issues with newer builds.
Everything is working like a charm! Now im going to finally give lineageOS a try
I used Chainfire's SuperSU 2.79 stable.
Edit : Everything is working flawlessly! I'm running the lastest LineageOS nightly with root (Chainfire's 2.79). Followed their instruction and installation was smooth as butter. I should also point out i flashed the lastest official TWRP which seems more stable than the one @KwesiJnr suggested. The one he suggested was giving me some "can't read X partition" in red text everywhere in the log section, which the official one doesn't do. It was doing his job properly anyway though.
I can't thank @KwesiJnr enough, it helped me find the single mistake i was making.

Yeah, like I mentioned before that was the base TWRP you needed to flash first, before any of the newer ones. You weren't intended to use it indefinitely.
There's a lot of Dev love for our device now and support is growing ... exciting new ROMs cropping up. Don't hesitate to try them out.
I have a new (3 day) that updated to b25. Was and is totally stock. Not happy.
Mar was way better on battery and performance. I have downloaded and renamed
b15 factory ota and placed in the sdcard. System update reports a valid update but before I
commit to doing this I wanted to verify with the community that it is safe to do.
After I do this update I am wondering if I can find a factory ota of mar if I can do the same thing again.
Thanks in advance

It's really simple actually: if you install B15 your data will be wiped, after that just skip everything and update to B29 (is B29 the latest? I have a G, dunno) and then use it. What you describe is not the actual performance that it should have, it's your specific case obviously.
I know what you want to do - if you want to remain TOTALLY STOCK I think you are out of options as I don't know anywhere that you can still download the stock ZTE B29 marshmallow. If you are willing to unlock your bootloader and install TWRP then somewhere in here DrakenFX has a B29 rollback that works great - it just won't work with stock recovery

All I really want is to remain stock but rooted and with TWRP for recovery for Nandroid backups. The B25 will not let me unlock the bootloader with Fastboot and when running MiFlash the phone is visible but getting "Hello packet error" I have read another method with fastboot but have not tried it yet (below). Somewhere I read that B25 was the problem and you had to downgrade and the MiFlash method was recommended.
adb reboot bootloader
fastboot devices
fastboot oem unlock
fastboot reboot
I did everything but the first entry.
Thanks for any suggestions.

Go ahead with your rollback to B15 - that will let you unlock and install TWRP. Once you have TWRP go to this thread https://forum.xda-developers.com/axon-7/development/rom-guide-updates-to-stock-files-via-t3469484 and in post #2 you will find A2017UV1.0.0B29_RollBackModded.zip. Flash that, then flash TWRP again (you have to flash TWRP again ONLY if you want to keep TWRP as this flash file will automatically reinstall stock recovery). Also note on B29 I had to use SuperSU 2.65 (not the current one) for root.

Wait - you wanted to stay stock? You didn't actually have to unlock if you wanted to. Just by using the update.zip method with some Marshmallow zip you could get to MM, and then you can update to N and you surely won't get the same problems that you've been having...
For example my G is on 7.1.1 and I get 6h+ of battery (right now, 3h36m with 41% left) so your problem is just that your installation was bad. If you unlocked you might as well just do the process that the guy above described though.

OK on the A2017U units you need the official marshmallow B29 package to roll back, and that only works with stock recovery on a clean B15 N install. The Rollback package I told you to use earlier will roll you back to B29 marshmallow NO MATTER WHAT YOU ARE USING (I have used this a lot, and OBVIOUSLY there are differences between the the A2017U version in North America and the A2017G version in Europe). If you want stock and rooted, I personally recommend B29 marshmallow over B15 Nougat, but either way go for it (I think the marshmallow had a much better radio than any of the Nougat packages). If you are interested in TWRP and root, I found B29 marshmallow much easier for both, and the marshmallow version of android also gives you Xposed, but back to your first post, you mentioned wanting marshmallow, and this is the best way to get it.
Step by Step method
1. Roll back to B15. Use the update.zip method. It will factory reset your device so backup everything you can't lose
2. Use MiFlash to unlock and install TWRP - check that thread on XDA for instructions.
3. (If desired) In TWRP, install the B29 marshmallow rollback. Do not reboot into system afterwards.
4. (If step 3 is done) In TWRP, flash TWRP. The marshmallow rollback will overwrite recovery with stock recovery
If you do this you will have exactly what you wanted in your original post. I can personally tell you this works, as I have tried every custom rom on here and always wind up back at B29 marshmallow when all is said and done. It has never failed me, and it will never fail you either.
Hey guys, I wanted some help on flashing LineageOS 14.1 to my Axon 7 A2017G.
I've looked at a bunch of guides but they all seem outdated or way too confusing.
I tried to follow the guide under the "Axon 7 Toolkit " thread where there were some instructions on how to flash a rom for noobs and when going to test for fastboot, it says I don't have fastboot.
Tried to get fastboot by following some guide and using miflash but ended up doing something to my device where android asked for a password when i booted up, where as I didn't have a password and had to end up factory resetting my device. LOST ALL MY DATA
If someone could please give me a simple, easy to follow guide on how to unlock bootloader, and flash custom rom, I would be immensely grateful.
Also if there is a guide on how to restore back to stock rom and factory settings in case I need to send phone back to ZTE at any point that would also be helpful.
:good:
The toolkit guide is probably the easiest one.
Read the whole thread and try again.

LOSING ALL YOUR DATA will be something normal actually. If you want to go to LineageOS you will probably lose it a bunch of times...
Well it turns out the toolkit is not the easiest way. Do this:
You didn't seem to search. Use "Unlock bootloader easily" by WesTD. After that simply go to the LOS thread, and download the ROM, the Universal Bootloader, and the modem file for your phone (for the G). Get Magisk too. and GApps for arm64. ) Then enter TWRP, ensure that it's 3.2.1-0 or more, else update it (get the newer .img for ailsa_ii or axon7 and Install - Install image - Recovery partition). Format data, and make sure that it formatted with ext4 (it'll say -formatting with make-ext4fs or sth). flash the bootloader, then the modem, then ROM, then Magisk, then GApps. After that boot.

Or try this tool to unlock your bootloader....way more advanced by the way thnx @djkuz
Just install the axon 7 drivers, this tool and....UNLOCK with ease :good:
Also all files to revert back to stock, flashing modem, recovery... etc are well discribed there. Just take a peek there...
Just another advice : do read all threads carefully, no matter what you're doing, do backup regularly and all will be OK :good:

Followed your steps and managed to unlock the bootloader successfully. Afterwards I tried to flash TWRP using the Axon Toolkit and this error appears. Have 0 clue why. A little help please.

EDIT: nevermind, tried to boot into recovery and twrp booted, not sure why the error appeared though. thanks for the help!
Hi i've spent all of yesterday evening trying to piece together what to do from a bunch of threads and websites but really struggling.
I hope someone is willing to help me.
last year i successfully installed Oreo B01. I followed some random guides off Reddit and somehow after a lot of trouble and false starts, got it working.
I unlocked the bootloader, flashed TWRP 3.2.1-6 'by NFound', and updated to B01.
The TWRP version is weird, for some reason some of the buttons in 'advanced' section look like its in russian writing, and If i go to Advanced>More>Root and try and flash either Magisk or SuperSU, it doesn't work.
It says 'Error updating zip file '/rootdev/unmagisk.zip' and i cannot root the phone.
I want to install the latest B04 update OR even try Lineage OS 16, Or the Pixel experience ROM, or any other ROM.
Ideally i just want to install a Pie based ROM.
However I am nervous because it looks like you have to have the right bootloader to install the right things, or the right versions of TWRP to install certain things, and it is all very confusing.
Everyone on here seems to have about 10 different ways of doing things and i'm getting really lost in every single thread I read. Use EDL mode, No need to use EDL. Use the toolkit, Don't use the toolkit, use command prompt and fastboot, But my fastboot is broken, what fastboot do i need, etc..etc.etc............my brain is melting.
Can someone please explain which version of TWRP do i need to install any of the above?
Can i just install a new version fo TWRP and it will overwrite previous?
Can I install B04 or any another ROM from the same TWRP version or do i need different TWRPs/Bootloaders for different things?
EDIT: I also appear to have a broken fastboot - I have the same problem this guy has, first post.
https://forum.xda-developers.com/axon-7/help/help-fastboot-mode-missing-t3844466
so i'm worried if i try and flash a new TWRP it'll mess everything up because its not right the way it is now - even though i can get into recovery, i can't get into fastboot???
Then i'm even more confused - about all this 'use EDL' .......i don' thave an EDL cable, do i really need to buy one and install stuff in these modes?
