G950U1 Oreo to Nougat Possible?

Is it possible to flash back to Nougat from the Oreo beta on the US S8?. I've tried searching but I could only find information on the international version.

Follow the SMG950U instructions. Basically getting BLQ1 nougat flashed on the phone and then getting the update.zip for CRB8 and applying that in the Vol UP+Bixby+PWR boot.

Connect to pc with smart switch and it will give a downgrade option. At least it does for mine...

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?

Flash this instead so you keep TWRP.

Thanks.
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.

EEA 10.3.30 to 10.3.2.0 = anti rollback brick?

Hello.
Hope you can help because I'm kinda confused atm
My device is redmi note 7 lavender, came stock with EEA (european global) rom.
I recently unlocked the bootloader, installed twrp, tried a few roms (xiaomi.eu, crdroid, phh-treble gsi, etc). Currently using crdroid without issues.
Previous to all this I was using stock EEA 10.3.2.0 firmware and then sideloaded ota for 10.3.3.0.
According to this post this phone has ARB
What I'm wondering is if I were to go back to stock firmware, would I brick my device? Because the only available fastboot version for EEA is 10.3.2.0 which is older I guess, but I'm not sure exactly how ARB works and it that would trigger it.
Thanks in advance

I recommend that you do not return to the previous version, sometimes the ota bring changes in the bootloader, and you can leave it hardbrick as it happened with several Motorola, even with devices that have a Qualcom processor. Expect that someone else has done it or that the software is released to an equal version.
start to investigate the changes that were added
I leave this link you fence to interest move from the EEA to the global version

If you're asking specifically about turning back from 10.3.3 to 10.3.2, then there is no problem (I went from 10.3.3 to 10.3.2 to 10.3.3 again and everything is ok).

My RN7 is global, came with 10.2.3.0 as stock, I updated via OTA to 10.3.5.0, and I was wondering if I try rolling back to 10.2.7.0 (As I didn't find any rom of 10.2.3.0 for global PFGMIXM) it will trigger the ARB? thanks in advance (both have lvl 4 in adb query)

Don't. Just bricked my phone.

Sorry to bother but, did you bricked going from which-to-rom, using TWRP or the mi-flashtool?

Rolling back firmware only through twrp, trying to get previous drivers for international version which bug less on proximity sensor.
As the phone is unlocked I might have found a way to restore from brick without physically opening the phone. Will keep you updated.
Edit/Update: yipeee!!
Need to completely flash the phone based on the procedure detailed here. And reflash whatever custom ROM afterwards as you get back to stock.

Just rolled back from Global 10.3.5.0 to 10.2.7.0 with MI Flash Tool (fastboot rom type). 0 problems, seems you can rollback from your MIUI 10 ROMS of the same version(EEA with EEA, Global with Global, etc, and of course that these roms have same ARB 4), at least worked for me, posting this future records.

Actually firmware tool (as opposed to twrp) is the way I reset ARB.

Unlock Bootloader and Root Axon 7 on Oreo

I've just been given this phone.It's my first zte phone.Im a little familiar with unlocking and rooting as I came from The Honor 8 years ago.However everything about this phone is quite new to me. Would like some help with the different processes in order to maximize this phone's potential. I've looked here and there to learn more but most resources I've found were quite outdated. Furthermore I have some thermal issues with the phone im hoping to correct. So where and how do i start?

I would recommend to downgrade to Nougat first (if you are using stock ROM, there is a downgrade package by ZTE), then once in Nougat, use Axon 7 EDL tool:

Going back to Indian stock from Global

I have an Indian Redmi K20 which was on 11.0.3 India rom. I unlocked the bootloader, rooted and installed the global 11.0.5 because I wanted to try a custom rom. Now I would like to go back to Indian rom but I'd like to keep the unlocked bootloader (assuming it doesn't mess with official ota updates).
I tried flashing the Indian 11.0.3 with miflashtool but got an anti rollback error, so I had to flash 11.0.5.
How do I go about it?
