Flashing Nougat with TWRP without losing TWRP - ZTE Axon 7 Questions & Answers

Hi, newbie question here. I just got my Axon 7. Unlocked the bootloader. Installed TWRP. Made full nandroids of stock and rooted firmwares.
I would like to flash the new Nougat update. What would be the best way to accomplish this without losing TWRP? and what is the correct firmware to use? ota? Also can nougat be rooted? Just dont want to brick my new phone. Thanks

No TWRP flashable file yet.....but I'm sure it'll be soon.
You will need to be on the Nougat bootstack, but you'll have to search for that info.

Install stock recovery back, then flash stock nougat zip.
no wipes needed.
you can download the ota from asus support site.

nougat

Hi all,
Noobie questions sorry.
I have a xt1625 us retail version and I'm getting prompted to take the OTA nougat update.
However, I have unlocked bootloader and TWRP installed so it fails.
1) Is the stock nougat available as a zip?
2) Is my best option to relock bootloader and go back to stock recovery, in order to take the OTA?
3)Is there a stable custom rom that is preferable?
Thanks very much
update;
I reflashed the stock firmware using fastboot and the 16 ish commands needed.
After this I took the OTA update without issues.
You can re root your phone and reinstall twrp now.

Yes. bootloader remains unlocked, so I can root later.
for now I am satisfied, stock rom isn't too bloaty

Planning to buy G935W8, had a few questions

Looking to buy this phone soon but I was just wondering about a few things. Im buying the canadian variant G935W8.
1. Can this device be rooted on nougat as well or only marshmallow? Im buying it brand new so I think it will probably be running the latest firmware.
2. Is there any issues with unlocking the bootloader? Is it neccesary to do so if you want root and custom roms?
the bootloader is not locked on the w8 as its the exynos variant and yes nougat can be rooted its the same as 935f

Thanks. Also another question I had. If the phone comes with marshmallow and I root it will I be able to install nougat roms directly or will I have to update the bootloader and modem? In that case would it be better to update it to nougat first and then root?
Updating your phone would cause you to lose root anyways as the file structure on nougat is completely different then marshmellow.
Rooting also prevents OTA updates, so you would end up having to install nougat manually.
I suggest you upgrade your software then root it. You can use systemless root from magisk. Using TWRP just flash the latest magisk file and you are rooted. The file will automatically root your phone as part of the installation process.

If you get it with MM (highly unlikely) just don't do anything and you should get an OTA notification otherwise you can download Odin, google it as I don't have a link and nougat from here https://www.androidfilehost.com/?fid=457095661767144483 and you can flash it yourself now rooting is a little different then it used to be do a search on the s7 edge for the info on that
the reason is yes you will need to download the BL not sure about modem but you might as well do it too
I just rooted my G935W8 running 7.0 by following the instructions in the first half of this video.

How to revert rooted XT1572 on Nougat to unrooted stock rom

Hi,
I am looking for a way to revert my rooted XT1572 to unrooted state.
I guess I just need to flash a stock rom. But I have the impression there are no stock roms released for the XT1572.
Flashing to stock marshmallow and next upgrading via OTA to nougat might have been a solution. But I read several messages that downgrading to MM and next updating via OTA will brick the phone?
Seems to me that I am stuck with my current rom? Or is possible to flash an XT1575 stock rom on a XT1572? (I don't care about future OTOA's). I am just trying to revert it to a little more 'default status' before selling the device.
Some added info:
Currently my build number says:
NPHS25.200-15-3
Googling this number directed me to following page:
http://guofeng.io/moto-x-style-7-0-xt1572_clark_retla_ds_7-0_nphs25-200-15-3-official-package-root/
There I find following file:
XT1572_CLARK_RETLA_DS_7.0_NPHS25.200-15-3_cid12_subsidy-DEFAULT_CFC.xml.zip
Would it be reliable to flash this to my device? Or should I also pay attention to other things?

Only for:
Latin America, Dual Sim.
Do you have twrp?
Magisk? SuperSu? Stock Twrp's backup?
You cannot take the Nougat update once you go back to MM. It will hard brick your phone. You kind of have to be on the same security path from what I read. Google has started to not let you downgrade do to security reasons. Sorry I have a MXPure but it almost identical as how to.....except for firmware. To unroot the phone completely you need the stock firmware associated with the phone or a stock unrooted TWRP.img.

Have TWRP, Magisk but stock backup (shame on me).
I wouldn't if the stock rom is from a different region but I guess a stock rom for dual sim will not work on a device with only one sim.
Would it be an option to use someone else TWRP backup?
If you didn't modify system partition - simply unroot with magisk manager app & format data/f.reset with twrp.
Stock recovery - you should ask here(or another thread) - maybe someone will upload it(can done with flashfire app).
I didn't see any backup for xt1572(Nougat). @blondie99
Thanks

From Nougat to MM for recovery

I have Custom ROM stock nougat
Can I install only the MM bootloader, do full wipe, and install a custom MM ROM, just for recovery?
Downgrade for recovery?
I'm confused about what you want to achieve, are you asking if you can downgrade to stock marshmallow from stock Nougat, to flash a custom marshmallow ROM?
If so, you could downgrade, but I would strongly recommend not using OTA updates on the stock marshmallow ROM if you downgrade, else you may hard brick your device. In most cases, you can't downgrade the bootloader in fastboot.
I'm not sure what you are asking for about recovery, can you elaborate?

You can even stay on nougat firmware, there's no need to downgrade as nougat is official released and available for all countries
