Upgrading from B170 to B313/Downgrading back to earlier version

Hi guys,
New to the forum here. I've flashed B170 a while back to get the most stable Lollipop edition, but I'd really like to try Marshmallow. The thing is, I can't figure out how to downgrade it back to B100/B121/B130 or to Upgrade it to B313. Is it possible to do either of those two things without an unlocked bootloader? There doesn't seem to be a way of flashing any packages on the phone, so I've sort of resigned myself to having to flash it via adb, but is this possible when I don't have an unlock code for the bootloader? Thanks for any help; I've really read through all the threads, but I couldn't come up with an answer.

Hi !
In order to upgrade to MM, you will have to downgrade to an upgradable version like B140. All the things you need are in the MM Upgrade topic of this forum.
In order to rollback from MM fo Lollipop, everything is explained in the same topic but you'll have to download a temporary system (B300) and then you'll be able to downgrade. Anyway, everything is in the MM Update topic.
I don't think you have to unlock bootloader to do all that but it would be easier because you would be able to use Honor 7 Multitool which is a software that does everything for you in no time
Good luck (MM version of the Honor 7 is awesome !)

Thanks for the reply! However, you can't use the B300 rollback on B170 (which is a Lollipop rom), can you? I've read the Marshmallow topic, and I was none the wiser - I can't seem to figure out if there's any way to get back to an upgradable version without flashing with the Honor tool (which requires an unlocked bootloader, non?). Sorry for the n00b-factor!

so many treads around here described the solution to do! Please use the search engine too
read following from there: http://forum.xda-developers.com/showpost.php?p=64673136&postcount=74
and...
try to flash the B313 Rollback file first!
Maybe it will stop with "not successful!" nearly ~93% but THIS DOESN’T MATTER! a reboot should bring you to interim B300. Then you should be able to flash the B121 Full update out of your dload folder from your internal SD. If this work, you should be able to update to B313. You do not lost your personal data, but make a backup to be sure!

NXTL-AL10 Firmware upgrade

Hello, ive been surfing this forum for a while, it helped me to change the firmware of my NXT-AL10 to the international versión, using Fastboot but the versión i was able to install is very old, (NXT-C900B133), it has a few bugs, but at least i got rid of the chinesee software.
Now im trying to update to the new Emui 4.1 the B320 firmware or the newest available, but i allready tried to updated using the dload method, but didnt work, i tried at least 3 diferent firmware version, the only version that i havent tried is the NXT-AL10 – NXT-AL10C00B350 because i believe that it will install again the chinesee version.
Can anyone point me on how to update my NXT-AL10 to the newest international version available without bricking my phone?
i apreciate!

It's supposed to be as easy as flashing the B321 firmware via twrp, just as you would flash any ROM regardless of which variant of the phone you've got. I'm not sure what you're doing wrong here.

Thanks, the truth is that i have technically zero experience with this, it was actually a miracle how i flashed it, i use this thread to find my way to do this: http://forum.xda-developers.com/mate-8/general/howto-load-international-mate-8-t3293619 but i have no idea on how to use twrp.
On the guide that i followed, it was very detailed, it had the download links, and i even had to pay 4 Euro to get my phone bootloader unlocked, but the guide was very explicit.
Now that the booloader is unlocked, and i have a flashed rom, what would be the method, is there a guide like the first one, but with the latest firmware?

What guide , rom should i use for A2017G Europe (IT)?

Hi everyone
I bought ZTE Axon 7 (A2017G) from Italy Amazon

The guide from Controllerboy works perfect ( advice read it more than once ) , the axontoolkit works too.
If you decide to go with custom rom you will loose ZTE Dolby,
but viper works good, but there are debloated stock roms which you can use with Dolby and root.
Unlocking the bootloader is always helpful, if you decide to use custom recovery and root, because if you mess up anything you're mostly lost with a locked bootloader.
Unlocking the bootloader will completely wipe your phone, better you copy your important stuff to PC.
If you just want to update your phone copy the latest official
firmware to the external SD card and use the update function.

This is a bit outdated, you can follow the guide on mm or n, doesn't matter. No need to down or upgrade before.

After you did the unlock, the twrp update and flashed the Los thread bootloader + modem you can use this rom, guess this is what you want:

@am2006 it seem strange that you don't receive OTA update. It is seem that the seller had done something with the phone (properly install A2017G on A2017 chinese model). Before doing anything, you must know you model, cause A2017G brick is pretty hard to fix

No I think the last update in Italy is MM, but I'm not sure, the device is new and I check the model and SN on the mobile and its cartoon, it is matching

I recommend using stock Nougat. Stock ROM has pretty good camera, Dolby, DAC which you will missing when using custom ROM. (Stock MM is bit crappy, ZTE has fix a lot after several update).
Beside, RR is very good custom ROM.
Official Xposed does not support Nougat yet, there is an unofficial one but not work with stock Nougat, I haven't try on RR

There are multiple iterations of Dolby made as a Magisk module. Magisk works perfectly on both LineageOS and Stock rom.

Back to stock ROM. How?

Hello guys,
Im using an ZTE Axon 7 with unkocked bootloader, rooted, and using a custom ROM and twrp. I **** to try the original and latest version of the official ROM to see how well the performance are. Is there a package for this that can be installed using TWRP and after it has been installed, my phone is in the original state again?
I saw an update on the ZTE website from 25/07/2018. (Version B35) Is this Android 8?
https://www.zteusa.com/axon-7
Can I install this package by using TWRP aswell?

Flash a zip package in twrp. But flash an twrp image after the rom. The stock rom overwrites the twrp with stock recovery.

Thanks! So, no matter wich bootstock Im using, I can just install the zip from te ZTE website using TWRP and that's it?
EDIT: on the website, there is only A2017U model. No G or A. Does this matter?

That is also an option. But I still prefer the latest version from te website as I hope that this is Android 8 and want to really have it at factory stock again.

The B35 (U-version) is 7.1.1
Try this : https://forum.xda-developers.com/axon-7/development/rom-slm-dfnr-t3744388
It's totaly stock or at least derived from the B35 that you want.
Or make your day and try this 8.0.0 : https://forum.xda-developers.com/axon-7/how-to/official-beta-android-8-0-0-v2-10b12-t3797085
Beta, U version based but definitely worth a try
Or go back to factory with the @djkuz EDL Tool. The B35 is in the OP. https://forum.xda-developers.com/axon-7/development/axon-7-edl-tool-flash-backup-restore-t3750759

B35 (from that site) is Nougat, not Oreo.
Oreo was not released officially so you won't find it in the ZTE website.
The current release (B12) is a -buggy- beta and missing some features. It's really not worth it. Battery life is atrocious (probably less than 2hs SoT).
You're better off with B10 (latest for A2017G) or B35 (latest for A2017U).
Those are the latest official firmwares for the phone and both are Nougat 7.1.1. Pay no attention to the numbers, as B10 is identical (update wise) to B35. Flash whatever you like. There's really no other option.
If you prefer the original stock experience with nothing touched or removed/added, you will have to flash a firmware via EDL mode. But that way you lose TWRP unless you replace recovery.img with a compatible TWRP version before flashing with Xiaomi Flash and your device is completely erased.
Forget about Oreo for the moment.

Okay sounds cool I'll rebrand the question remained is what brand has the latest update?(Please provide a link to .zip update) and the last question is,if I rebrand before I install oreo what exactly happens I turn on my phone and it has a frimware from Africa but its brand is now China!Will that be able to turn on?Or I should use TWRP to install Chinese firmware from SD card.

Since I'm an android developer I need to have multiple os if possible.Has anyone tried this Or any better one?Can I use it in this case?

https://forum.xda-developers.com/mate-8/general/guide-how-to-downgrade-mate-8-emui-5-to-t3515202
I found this and it says the nougat version must be b500 but mine was b560 and tried to install the rollback and it failed again.I don't know what to do?I need my phone.
Couldn't find any download link of b500 did you do that on your b500 or b560?
If b500 please give me a link of NXT-L29C185B500

Tried again and it didn't give me error this time the point is that it doesn't run on B500 it makes your device B500!

After installing marshmellow the bootloader is locked again!
