Possible steps for updating to nougat b15? - ZTE Axon 7 Questions & Answers

Ok, hello everyone, I have a quick question. Would the steps for updating to nougat be?: 1) Download and install B29 modded in twrp to reset everything back to stock 2) If fastboot doesn't work flash bl_unlock file from twrp after using axon7tool to flash twrp to get fastboot back? 3) flash back stock recovery and download the update? 4) Install b15 and then go back to edl and install twrp and then flash the unlock again 5) flash modem fix2 to get partitions to work? 6)profit?
so would that work? i am half way through this. i just got back fastboot and was wondering if this would work to help get to B15. I want to see how botched the b15 update is. Feedback would be great for US peeps who did this already to get to b15 and if a better method is there that you used. by all means talk to me like a 5 year old, I am stupid when it comes to brickable chances with modding. And after i do it and get it from you guys help i will write a tutorial and publish on XDA

Sideload Marshmallow from Lolli 1.17.40.1106

Hi all,
needing help upgrading to MM.
I'm stuck on 1.17.40.1106 since I unlock the bootloader I can't receive further updates.
I've read that to be able to upgrade to MM you need to have .1531 firmware but since I'm stuck, can I sideload MM 21.40.1220 from Lolli 1.17.40.1106?
I have TWRP installed but not rooted.
First if you want sideload u must in "STOCK recovery"
And Seccond if you want update to MM u must have final firmware of LL. Go to asus.com check ur firmware version, If you are using last LL u just download MM firmware copy to sdcard and go to recovery-->apply update from sd card-->choose firmware MM and wait it update
.....
Dont flash firmware of asus.com if u use custom recovery it will brick your phone....
Thanks Val.
I'm having status 7 error both in stock recovery and twrp, another reason why Im stuck.
What are my options?
anyone?

you have twrp but no root? how does that work?
in any case, the Terms of Service of the Asus unlock tool says you will not be able to get OTA update after using. We have confirmed that the unlock tool communicates with Asus when you use it - we highly suspect it sends your phone information to Asus to prevent official OTA.
I would root phone and install ROM.
check this out for issue of installing official MM update with TWRP:

Thanks Eric.
I was reading the links you gave and have this questions:
1. Is it true that if I use custom recovery (TWRP) to sideload official firmware my phone will be bricked?
2. If I do "fastboot erase system" and flash full official firmware such as 1.17.1531, will it erase the custom recovery and go back to stock?
This way I can manually upgrade to MM once in stock recovery.

1)i think twrp will not flash the official firmware, like if you downloaded it from Asus or got the ota .zip.
2) i do not know that command but it scares me to look at it.
in the thread i linked to, was answer to y question about flashing the official MM stock image.

Ok.... I'm very confused:ZE551KL with 6.0.1 (MM)

Please forgive my stupidity - I'm a longtime Samsung Android user and this Fastboot/adb process is all new to me. Last time I used that was with Original TMOBILE Mototola G1!!
So, this is what I have: I had my device ( ZE551KL ) on LP, Bootloader unlocked with TWRP and rooted. 'Cause I first unlocked the Bootloader with the official ASUS app.
Then I installed the OTA ASUS MM version, but according to everyone, once one install the OTA upgrade, it relocks the Bootloader, correct? How can I test this??
This afternoon I put device in Fastboot mode and did a "fastboot boot twrp-3.0.4.img" and it worked!!!
It boot into TWRP and am busy making a backup now.
My Question: if my bootloader is still locked, how could I boot TWRP?
Can I try and 'Fastboot flash recovery twrp....' and will this work or am I going to brick the device?
Ideas? ( well, rather experienced advice, please)- as I would hate to brick my device.
The TWRP backup I am currently making - is that any good/helpful to anyone that can help us getting this device properly unlocked and rooted?
Thanks
I did try the official ASUS unlock tool on MM....
I forgot to mention that.
I did try the official unlock tool on MM, but the app just failed.
I opened an issue with ASUS regarding this, as their website specify version 1.16 'and later'
Does this mean I am good to flash TWRP??
Am I good to flash TWRP if I get this message??
You are good. I had unlocked the bootloader long time ago, and I have installed MM, they don't relock it back. It would be strange to do that, since once unlocked you lost the warranty... it would be like they will gave you back the warranty!
Dude, your bootloader is unlocked. You're good to go. Fastboot flash that recovery and go to town.
From your description it is clear that you have successfully unlocked your device. Once it is unlocked, you wont be able to lock it back. So there is no way to revert the process and it affects warranty. Now anytime you can flash TWRP with fastboot and install custom ROM. If you want to install Stock rom install stock recovery and use ADB sideload to install Stock ROM. if you have any other doubts visit my youtube channel [TheMobileShots] where i have provided the tutorial to do these things. Have a great day!

b25 Update

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.

By the system update.zip method?
Thanks
Also I would be happy to stay at b15 with TWRP and 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.

How to unbrick my ZTE Axon 7 mini b2017g

Dear Seniors.
I am facing great hardship because my phone is stuck at boot logo.
No booting in recovery mode to flash another rom.
I did unlock bootloader of it by using tuliptool with success. After that i flashed custom rom in it. after reboot it is happening that.
Please suggest to recover it.
Did you flash twrp after unlocking? Did you make backup of stock ROM? Perhaps find a version of the factory firmware and flash that.
Dear I have no backup and i flashed TWRP recovery.......
It is to aware you that i did relock bootloader now my phone is working properly. but i am unable to enter recovery mode. !!!
Now my phone is running android 6.0.1 B02
But i am failed to root this rom uptill now due above mentioned problem.

I found software update notification but when i update an error accruing while update. (This update not compatible with this device"
In easy words......... my recovery.img has been corrupted. I have no idea to get rid of this situation.
I planned to unlock my Mini's bootloader this weekend. After reading this post, I decided to act later until the root cause has been figured out.

Several people myself included have been able to use tuliptool to successfully unlock and root the device.
mine is hard bricked too. but I think it is worse than the case listed on the op.
if you want to hard bricked these are the steps:
follow the procedure to install the Spanish ROM 6.1, than another android m b12, than finally the android seven......use tulip tool and install twpr fine, root ect. amazing ROM.......buuuuut......I lost my IMEI somewhere in this process, and the original FTM which had a small menu changes to another static one, without the menu.
I needed this menu to open the com port to fix the IMEI. than I had the brilliant idea to re-flash android M via twrp (without modifying the zip file to remove the recovery, something I knew so well from the older axon mini).
results:
-lost twpr because the stock ROM wrote over it,
-cannot boot the OS because I flashed android m but the phone had the aboot 7.
-i now have a brick
I need a genious to sujest something to bring it back to life........sh....t...sh...t.....sh...t
any chances I could inject aboot7 via ADB through my dead recovery which somehow the phone recognises? ADB shell still seems to be working
thanks

Help installing TWRP as zip file (no go through Fastboot)

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.
